IBM User's Guide, Thirteenth Edition

1 Introduction to UTCC

The mission of UTCC

The University of Tennessee Computing Center (UTCC) is charged with providing computing facilities and services for research, instructional, and administrative functions for the University of Tennessee system.

A brief history of UTCC

UTCC was established at the Knoxville campus on June 30, 1960, with the aid of a National Science Foundation grant. Two other grants have been received from the National Science Foundation for upgrading UTCC computing facilities. UTCC first occupied about one half of the area that is now the Remote 8 user work area (Remote 8), located in the Glocker Business Administration Building. UTCC's first computer, an IBM 1620 Model I with 20 kilobytes of memory, was installed in early 1961. On a typical day, about twelve users would come in to run programs written in one of the two languages supported: an assembler language called the Symbolic Programming System and a primitive version of FORTRAN. There were three full-time employees on the UTCC staff. Today, UTCC runs seven mainframe computers and over 200 microcomputers and workstations. More than 3000 user batch jobs and timesharing sessions are processed each day. Now there are more than 98 full-time employees on the UTCC staff. UTCC occupies the first two floors of Stokely Management Center (SMC) and areas in Dunford Hall. Remote user work areas are maintained on the Knoxville campus. UTCC also provides computer resources and services to the computing centers on other campuses in the University of Tennessee system and provides access to the National Science Foundation supercomputer centers.

UTCC organization

UTCC is divided into five main groups: Administration, Network Hardware Engineering, Operations, Systems and Network Software Engineering, and User Services.


Administration is responsible for the maintenance of computer records, charges and budgetary matters, direction with respect to policy, recommendations for expansion of facilities, and the allocation of resources.

Network Hardware Engineering

Network Hardware Engineering (NHE) is responsible for the installation and maintenance of network hardware, including physical connections to the "DCA" network and to the UTK Ethernet-based local area network (LAN). These two networks are described in sections and NHE also administers the campus installation of office LANs running the Novell Netware operating system and AppleTalk or EtherTalk LANs; such a LAN may be connected to the UTK Ethernet-based LAN. NHE administers a high-speed, statewide, wide area network called EdNet, which connects UT Knoxville, UT Memphis, UT Martin and the UT Space Institute, as well as the State Data Center in Nashville. EdNet is described in section


Operations manages the physical operation of all computer hardware, the reception of input, the distribution of output, and management of the tape library. Staff members are responsible for the daily scheduling of jobs, maintenance of the equipment, and staffing of UTCC microcomputer labs and remote facilities.

Systems and Network Software Engineering

Systems maintains the several operating systems at UTCC. This includes the documentation of installation-dependent characteristics of the supervisory system, assemblers, compilers, and other software systems at UTCC. The systems groups have the responsibility to remain alert to changing computer technology and its potential advantages to UTCC. Network software engineering functions include evaluation, recommendation and maintenance of networking software products.

User Services

User Services provides consulting services on supercomputing, microcomputers, mainframes, workstations, networking, mathematical software, statistical packages, programming languages, graphics software, word processing, and many other areas. User Services staff members are also engaged in the production of user documentation, the maintenance of application software, educational services, and statistical consulting. Persons who wish to open an account or require additional information about UTCC systems or services should call (615) 974-6831.

UTCC user's guides

The IBM User's Guide , U01-0001, and the VAXcluster User's Guide , U01-0572, are reference manuals for beginning and experienced users of UTCC facilities. The IBM User's Guide describes the use of the IBM VM/CMS and IBM MVS/ESA systems; the VAXcluster User's Guide describes the use of VAX/VMS. Each manual explains administrative policies and operational procedures for all users of UTCC facilities, and each specifies other sources of information about UTCC. The IBM User's Guide and the VAXcluster User's Guide are sold at the UTK Book and Supply Store.

UTCC documentation (U01s)

UTCC produces documents, commonly called "U01s," which describe the use of the software available on the UTCC computers. The majority of these documents are available online and can be accessed using the PRTDOC facility. For information on PRTDOC, enter help prtdoc on CMS. U01s that are not online are available from User Services, 200 SMC, 974-6831, at the UTK Book & Supply Store, or on the UTCC Macintosh CD-ROM server (see section For a complete list of U01s currently available, see Index to UTCC Publications , U01-0415, available online through PRTDOC or from User Services at 200 SMC. For online information on CMS, enter u01index

UTCC Newsletter

The UTCC Newsletter is published monthly and contains items of interest to UTCC users. There is no charge for the Newsletter, and users may subscribe to it by sending their names and campus addresses to the UTCC Newsletter editor, 200 SMC. Copies of the current issue of the Newsletter are available at the receptionist's desk at 200 SMC.


Many sections of this document contain references to commercial manuals for further information. UTCC makes every effort to place documentation manuals where they can be accessed by users. Nearly all remotes and terminal rooms on the UTK campus have a list of the manuals that are available and their location on campus. This list is contained in the manual rack; consult the index to the manual rack at the remotes. The manuals at UTK are kept current with the existing UTCC systems and with all technical newsletters issued for any manual in the set. The manual set also includes recent issues of the UTCC Newsletter , the IBM User's Guide and the VAXcluster User's Guide Users on other campuses should contact their computing installations for information on the availability of manuals.

Material on reserve

Manuals for mainframe computer and microcomputer hardware and software have been placed in the reserve section of the Hodges Library, and are available for three-day checkout by anyone with UT library privileges. The manuals are listed in the library card catalog and also in the UTCC document "Documentation and Reference Materials at UTCC," U01-0628, available through the PRTDOC facility.

UTCC Help Sheet

"The UTCC Help Sheet," U01-0627, which contains a list of facilities, available microcomputer software, and a map showing their locations, is available through the PRTDOC facility.

Literature from other organizations

UTCC receives literature and newsletters from other computing centers and many national and international organizations. These materials are available for examination at 200 SMC. Interested users should contact their UTCC consultant at 200 SMC, 974-6831.

Obsolete manual giveaway

UTCC frequently has manuals that have been rendered obsolete by publication of a new version and/or the installation of a new release of the software. As such manuals become available, they are placed at Remote 8 each Monday. The manuals are given away on a first-come, first-served basis while the supply lasts. Most of these manuals are upwardly compatible with the newer ones; however, determining their usefulness is the responsibility of the user.

Educational services

CAFE (Computer Access for Education)

CAFE accounts are available for University of Tennessee, Knoxville, students, faculty members and staff on the University of Tennessee Computing Center (UTCC) computers. The CAFE account, provided at no charge to the user, can be maintained as long as the individual is a UTK student or employee. (Accounts are available on both the VAX/VMS and the VM/CMS systems. UNIX accounts should become available during the 1992-93 academic year.) These accounts are designed to provide enough resources to carry out many tasks. There are limits, but in normal operations CAFE users should be able to use services such as electronic mail on campus and to other universities, online conferencing, word processing, text formatting, and printing. CAFE accounts are not a replacement for research or class-related computer accounts with UTCC and should not be used as such. Class and research accounts should continue to be opened as in the past through departments sponsoring research and offering courses with computer-related work. CAFE accounts are designed for a moderate level of computer use to give the account holder access to services such as electronic mail; they should not be used as a substitute for departmentally opened and funded accounts.

Getting a CAFE account You can obtain a CAFE account by registering for and attending a one-hour orientation session. You must bring the current edition of the appropriate user's guide (the VAXcluster User's Guide for VAX/VMS accounts and the IBM User's Guide for VM/CMS accounts) and your valid UT ID to the orientation session for which you register. User's guides can be purchased at the UT Bookstore.

CAFE orientation and registration During the orientation session a UTCC consultant will explain the Code of Computing Practice, how CAFE accounts work, what resources are available, where to get help, and how to use the user's guide. Registration for an orientation session is done by computer. You can access the registration program from a UTCC terminal or a microcomputer connected to the "DCA" network. Terminals are located across campus in academic buildings, residence halls, and the Hodges Library (see section 1.6.3 for locations of facilities).

The registration procedure

1. Turn on the terminal and wait for the OK message to appear on the screen. 2. Press the RETURN key until the prompt ENTER HOST NAME OR HELP> appears. 3. Type the word VAX and press the RETURN key. 4. When the prompt USERNAME: appears, type the word CAFE and press the RETURN key. 5. When the initial screen of the registration program appears, follow the directions and enter the information according to the prompts. Please note that you must see the screen "CAFE registration completed" to be registered successfully for an orientaton session. For more information concerning CAFE, contact a CAFE consultant in UTCC User Services, located in 200 Stokely Management Center, by calling 974-6831.

Intensive training seminars (ITS)

Intensive training seminars in mainframe VAX/VMS and IBM MVS/ESA utilization are conducted for faculty, staff, and students who will use UTCC facilities. One of the courses is taught the week before the Spring term and the other before Fall term classes start. Contact UTCC at 974-6831 for more information.

Short courses

UTCC offers noncredit short courses each semester on UTCC application software and operating systems. These short courses are free to UTK students, faculty, and staff. A schedule of all short courses is published by UTCC each semester and is available at 200 SMC, at all UTCC remotes, and online on all mainframe computer systems. Short course topics include the use of timesharing facilities, the use of microcomputers, word processing, statistical packages, mathematical programs, and vector processing available at UTCC. Special short courses designed to meet the requirements of particular groups of users may be scheduled. For more information, contact the Short Course Coordinator at 200 SMC, 974-6831.

Videotaped short courses

A number of short courses are available on videotape in the audiovisual department of the Hodges Library. Handouts for the videotape courses are available at 200 SMC. For more information on UTCC videotaped short courses, see "UTCC Short Courses on Videotape," U01-0443.

Computer-aided instruction (CAI)

There are a number of Computer Aided Instruction (CAI) courses for software on the various operating systems at UTCC. Some of these CAI courses are listed in the table below. For detailed information on a particular operating system, refer to the appropriate user's guide or U01.

Course System CAI Help

Consulting services

All project codes issued by UTCC are assigned a UTCC consultant. Users may contact their consultant to make appointments for consulting services or to get information. To receive adequate consulting assistance, users should make appointments with their consultants. UTCC consultants serve as a liaison between users and UTCC's computer software. The consultants can direct users to the appropriate software, but the techniques required should be clear in the users' minds before they make appointments with their consultants. UTCC consultants are available to assist users who are unable to determine the cause of program errors. In particular, users should contact their consultants for assistance if they suspect that hardware, software, or operator errors have occurred during the execution of their jobs. UTCC consultants can help users design the formats of questionnaires and data sheets so that transfer of the data to machine readable form will be as easy as possible with a minimum of errors. This service also applies to data that will be optically scanned. A consultant may suggest a program modification which may not be helpful. In such cases, the department is still responsible for any charges which may be accrued. Users who wish to change consultants should contact the Manager of User Services, 200 SMC, 974-6831. The consultant assigned to a class project code can aid in the selection of programming languages and compilers and in the explanation of control statements. The consultant can help the instructor with the preparation of programs and the allocation and release of tape and disk space. The department offering the class is billed for the time the consultant spends working on the project code at the educational consulting rate shown in the "UTCC Schedule of Charges," U01-0562. This includes consulting with the instructor and students.

Statistical consulting

User Services includes a group of applied statisticians and a faculty associate from the UTK Statistics Department. The statistical consulting group offers many of the services performed by formal statistics laboratories at other universities. This group assists researchers on matters pertaining to research design and statistical planning; data management, analysis, and interpretation; and the effective presentation of statistical information.

AppleShare network installation services

UTCC, in cooperation with the Office of Administrative Computing (OAC), supports the use of AppleShare servers for Macintosh microcomputer LANs using AppleTalk/EtherTalk protocols. AppleShare and the AppleTalk/EtherTalk network protocols can operate across the UTK extended Ethernet. A needs analysis team is available to discuss Macintosh LAN options with individual departments. Call UTCC for information about planning an AppleShare LAN.

Novell network installation services

UTCC, in cooperation with the Office of Administrative Computing (OAC), supports the use of Novell Netware as the primary network operating system for PC-based machines at UTK. This operating system is supported as a LAN and across UTK's extended Ethernet. A needs analysis team is available to discuss LAN options for individual departments; Blanket Purchase Orders have been established to purchase the needed components to install a Novell Netware LAN. Call UTCC for information about planning a Novell network LAN.

LISTSERV capability at UTCC

Portions of the following text were adapted from "Revised List Processor (LISTSERV@FRECP11), Release 1.5d," written by Eric Thomas of the Ecole Centrale de Paris in 1986. UTCC has installed software to enable its users to own and moderate a LISTSERV discussion group locally. LISTSERV, which stands for "list server," is a mailing-list server which was designed to make group communication easier. People with a common interest (e.g., network protocols, issues related to handicapped people in education, system administration problems) are grouped in a list, which is stored on LISTSERV. They then can communicate with all the people on the list by sending mail to a special network address (e.g., SAS-L@BITNIC). Any piece of mail sent to these special userids is automatically distributed by the list server to the people on the list. LISTSERV is a convenient way to meet people and participate in interesting discussions/forums. For more information about establishing a LISTSERV discussion group, call your UTCC consultant at 974-6831. It should be pointed out that there are hundreds of LISTSERV groups already established at other institutions, to which UTCC users can subscribe by sending electronic mail to the list coordinator. For more information about these LISTSERV groups, on CMS enter HELP BITNET or HELP INTERNET and select the topic "Information about LISTSERV discussion groups."

Public data bases

In cooperation with the University libraries at UTK, UTCC maintains tape copies of data made available by various state and federal agencies. All data tapes which are available at UTCC are cataloged and classified in the catalog of the Hodges Library, Knoxville Campus. Users who need standard tapes of this type but cannot locate them in the library catalog should call their UTCC consultant at 974-6831 to determine if they are available. If sufficient need exists, the library can obtain the data tapes.

Data tapes available to UTCC users are listed below. Documentation describing the use of the data tapes is available through the PRTDOC facility for those tapes that list a U01 number under "For Information."

User software

Users who wish to acquire mainframe software for their own use should first determine whether the needed program capabilities are already available, either directly from the UTCC program library or from some other user who has already acquired the desired software. Users who acquire software may place it in their own program libraries. Users who wish to make their software available to other users may publicize this fact in the UTCC Newsletter by contacting the editor. If after using the program a user feels that a particular software item should be supported by UTCC, a written request for UTCC program support should be made to the Director of UTCC, 200 SMC. The request should be accompanied by complete documentation of the function of the software, the methods used, maintenance procedures, computing system requirements, and user instructions. The request will be evaluated on the basis of the software's capabilities in relation to existing software, the number of users, and the frequency of use. It is the user's responsibility to solicit enough use of a piece of software to warrant its inclusion in a UTCC program library. If UTCC assumes support for a software item, it will be placed in the appropriate program library and made available for all UTCC users. If the request for software support is denied, the documentation will be returned to the user along with a statement as to why the software was not deemed suitable for inclusion in a UTCC program library.

User comments

Users may make comments concerning UTCC procedures or inquire about existing policies through the COMMENT facility on VM/CMS, VAX/VMS and Sun/SunOS (UNIX); through the comment boxes located in SMC M1, Remote 1, Remote 2 and Remote 8; or by letter to the UTCC Newsletter Editor, 200 SMC. All comments are answered. Users are requested to give their name, address, and telephone number with the comment, since it is sometimes necessary to obtain more information about the comment before it can be answered. If the information is useful to other users, the comment will be published in the UTCC Newsletter policies and procedures by contacting the Director of UTCC, 200 SMC, 974-6758.

Computing and office systems reports

UTCC subscribes to reports from Datapro Research Corporation. These reference manuals comprise a source of up-to-date information about computing and office system hardware, software, services, and companies.

Computer Select database on CD-ROM

The following description of the Computer Select database was adapted from Computer Select User's Guide , 4th Edition, edited by Johathan Pollard (Cambridge, MA: Lotus Development Corp., 1988). The Computer Select database on CD-ROM is located in the UTCC commons area at 200 Stokely Management Center. This database gives immediate access to current information in over 150 computer-related periodicals. With it, you can access information about product specifications, reviews, technical tips, manufacturers' profiles, and industry news. Computer Select consists of six sections:

Users who want to use the Computer Select database should contact their UTCC consultant.

Operations input/output assistance

Operations staff can assist users at SMC M1 (Remote 0) with the following:

1. Provide general information to users.
2. Supply information concerning job status.
3. Cancel jobs.
4. Receive reports of problems with UTCC-owned equipment.
5. Receive reports of network problems.
6. Receive user-owned tapes to be run on the UTCC system.

Operations staff can be reached at 974-6771 during the hours of UTCC operation.

Output delivery service

UTCC provides a delivery service to selected locations on the Knoxville campus for output produced at Remote 0 (Stokely Management Center). The approximate departure times from SMC and the destinations served are listed below. Delivered output is sorted to the bin (or bins) provided at each delivery site.

Knoxville campus: 9:00 a.m., 12:30 p.m., and 4:00 p.m., Monday through Friday

*RMT1 (Ferris) Bins *RMT2 (Estabrook) Bins *RMT28 (Physics) Bins outside Room 209 *Dougherty Room 508 *Human Ecology Room 23 *RMT8 (Glocker) Bins Andy Holt Tower Room P204 (8:30 a.m. and 12:00 noon)

*Only as required when output is produced at Remote 0.

Note Agriculture campus provides its own pickup/delivery service. Because the runner delivers on foot, users are requested to limit materials sent through this service. On each run, the runners deliver only as much as they can carry. Users wishing delivery of a large amount of output through this service should allow several days each way for the delivery. If it is mandatory that input or output arrives at a certain destination at an exact time, the user should make other delivery arrangements. Users at remote centers not on the Knoxville campus should contact their local computing center for information about routing and delivery of jobs for their facility.

Hot line

To inform users of the operating status of the UTCC computers, UTCC has established a "Hot Line" at 974-4237. A recorded message describes the status of the systems for both timesharing and batch processing. The message will contain information about known system problems and system outages. The hot line information can also be displayed at a terminal, workstation, or microcomputer. How you access it depends on how you are connected to the UTK network. If you have a direct serial connection (i.e., when you turn on your terminal and press the RETURN key you see the ENTER HOST NAME OR HELP> prompt), then enter HOTLINE as a host name. If you are connected via a DECserver or Xyplex server (i.e., you see the local> prompt), then issue a C HOTLINE command. If you are using a workstation, or if your microcomputer is connected to the UTK Ethernet, you can access the Hot Line directly using its IP address,, or its fully qualified domain name,

Electronic mail directory

The function of the electronic mail directory is to facilitate the location of correct userids for use in electronic communications. The directory contains user name, userid, and node information. It may contain additional information, including the user's department abbreviation and office telephone number. To get more information about the directory, enter HELP UTSERVER on CMS.

Networks at UTCC

The following discussion is divided into two categories: local area networks that provide connectivity on the UTK campus and/or within the UT system, and wide area networks that provide access to other campuses and research institutions outside the UT system.

Local area networks on the UTK campus and within the UT system

On the UTK campus, the major networking tasks have been to connect users at remote sites to the UTCC mainframe computing facilities at Stokely Management Center and to connect scattered users to each other and to distributed computing resources. Presently, these tasks are accomplished through the use of three networking strategies. One is an Ethernet-based network using primarily the TCP/IP protocols; most new network connections are currently made to this network. Another, and older, medium is a terminal switching network based on software from Racal-Milgo Corporation; this second network medium is widely and informally known to UTCC users as the "DCA" network, because for many years the software used was from Digital Communications Associates. New connections to these two networks are managed by the Network Hardware Engineering section of the Computing Center, in cooperation with User Services. These two campus networks are discussed in the next sections, and A third networking medium for connecting remote UTK users to IBM mainframe facilities is based on IBM's Systems Network Architecture (SNA) specifications. Most of the more than 1,000 terminals connected to IBM hosts via SNA are for administrative use.

The Ethernet-based network at UTK

Ethernet is a high-speed, local area communications network medium. At UTK, the Ethernet-based network connects personal computers, workstations, mainframes, printers and terminal servers, enabling communications between nodes and with the UTCC timesharing systems (the VAXcluster, CMS, MVS, and Sun/UNIX) and access to larger networks, such as the Internet. The Ethernet medium provides a high data rate and rapid access to data in remote locations, making large file transfers practical. The growing campus Ethernet network presently connects many of the major administrative and academic buildings. The Ethernet medium is also used on campus for networks of personal computers, called LANs, or local area networks, connected by Novell Netware software or Apple software. An office LAN may or may not include connectivity with one of the larger, campus-wide networks. These networking services can be established in cooperation with the Network Hardware Engineering Group and User Services. Ethernet supports many different protocols, including TCP/IP, LAT, DECnet, IPX, SPX, AppleTalk, EtherTalk, and XNS. The choice of connection protocols determines the network services that are available. Some of these protocols are briefly described in the following sections.

AppleTalk is a network system designed by Apple Computer, Inc. to connect Apple Macintosh computers, printers, and a variety of network services in a local area network (LAN). AppleTalk is supported on several media, including LocalTalk (from Apple Computer, Inc.), PhoneNet (from Farallon Computing), and Ethernet. AppleTalk nodes (computers, printers, servers, etc.) can access the campus-wide Ethernet either directly (e.g., using Ethernet boards), or indirectly through LocalTalk/Ethernet gateways. Using Shiva FastPath gateways, several AppleTalk networks on the UTK campus have access to the campus-wide Ethernet, thus forming a large AppleTalk internet. When directly connected to the Ethernet, an AppleTalk node usually runs EtherTalk (AppleTalk on Ethernet), but other access methods are also supported.

DECnet is a system of networking software and hardware that allows several forms of communication between Digital Equipment Corporation (DEC) computers. The Administrative Information Systems VAX, the UTCC VAXcluster, the Sun server (UNIX), the College of Engineering VAX, the Space Institute in Tullahoma VAXes, and the Biomedical Information Transfer Center at Memphis VAXes are connected by this network. Functions available to users include: accessing files on remote nodes, logging into remote nodes, using utilities such as PHONE and MAIL to communicate with users on remote nodes, and communicating between tasks on separate nodes.

IPX/SPX (Novell Netware)
The IPX and SPX protocols are the native networking protocols for Novell Netware. These protocols are supported across the UTK extended Ethernet. Packet drivers are used to allow the concurrent use of IPX/SPX and TCP/IP. This allows simultaneous use of TCP/IP software like FTP or Telnet and access to a Novell server.

Digital's Local Area Transport (LAT) protocol operates on Ethernet to provide access to computing resources. The most frequent use of the LAT protocol is between terminals connected to terminal servers and LAT hosts, i.e., the UTCC timesharing systems (VAX/VMS, CMS, MVS/TSO, Unix). Other connections supported on the UTK campus include those between LAT terminals and the "DCA" network and between LAT hosts and printers attached to terminal servers.

TCP/IP, or Transmission Control Protocol/Internet Protocol, is a suite of networking protocols. TCP/IP is the predominant method for connecting dissimilar hosts and is the primary networking protocol in use at UTK. These protocols are required for access to Internet and some other networks. TCP/IP protocols have been established on UTCC's VM/CMS, VAX/VMS, MVS/ESA, and Sun/SunOS (UNIX), and on more than 2,000 workstations, IBM PCs and Macintoshes on campus. The TCP/IP protocols provide a high-speed link for remote login and file transfer (TELNET and FTP). Remote login is a service not provided by some other networks, such as BITNET.

"DCA" network (Racal Milgo Series 300 network)

Access to all UTCC timesharing services (the VAXcluster, CMS, MVS, Sun/UNIX) is available through a terminal port selection and multiplexing network called the Racal-Milgo Series 300 system. As mentioned above, by well-ingrained habit, UTCC users still refer to this network as the "DCA" network, and, for clarity's sake, this document will do so as well. Terminals in the UTCC remotes and user work areas, as well as a few hundred "leased-line" terminals in many campus buildings, are connected directly to the "DCA" network. Alternatively, a terminal can connect to the "DCA" network via a telephone and modem. Note that the word "terminal" is used here to describe both actual terminals and microcomputers emulating terminals. The "DCA" network also permits access to the UT Library online catalog (choose host name LIBRARY) and permits dialout access to other systems (see section

Dial-in access to the "DCA" network
A terminal or microcomputer can connect to the "DCA" network by using a modem and telephone line. Connections are available through the following telephone numbers:

Supercomputer center access

As part of the national supercomputing initiative, the National Science Foundation has set up supercomputing centers at Cornell University, the University of Illinois, the University of Pittsburgh/Carnegie Mellon, and the University of California at San Diego. The University of Tennessee is an affiliate member of the Cornell, Illinois, and Pittsburgh/Carnegie Mellon centers.

Cornell National Supercomputer Facility

The Cornell National Supercomputer Facility (CNSF) configuration consists of two IBM ES/3090 600J supercomputers, each with six processors and vector facilities. Both machines run an extended version of the AIX/370 operating system. AIX/370 is IBM's version of UNIX for IBM/370 architectures. The Transparent Computing Facility (TCF) connects the two 3090's as sites in a cluster. The TCF cluster consists of one interactive 3090 site, two Networking Queuing System (NQS) batch 3090 sites, and two PS/2 sites which provide dialup access to the cluster.

Allocations UTCC is affiliated with the CNSF through the "Smart Node Program." This is a consortium set up by Cornell to serve groups of users at other institutions. Because UTCC is a Smart Node site, Cornell makes pre-allocated, non-renewable accounts available to UTCC users on Cornell's machines. The purpose of the pre-allocated accounts is to provide a means for UT researchers to evaluate the usefulness of the Cornell system for their projects. For additional time on the CNSF, all requests should go directly to the Cornell Theory Center, not to the NSF, and will be reviewed by scientific peers. This review process takes about eight weeks. Proposals requesting large amounts of time will be reviewed and subject to final approval by the Allocations Committee, which meets three times per year. Forms and additional information are available from UTCC.

Special support programs CNSF is dedicated to bringing high-performance parallel computing to the forefront of scientific and engineering research. To complement the two IBM 3090 parallel computers, during 1992 CNSF will incorporate into their production environment other UNIX high performance machines, such as a cluster of IBM RS6000s and a KSR1 scalable parallel machine from Kendall Square Research. Special support programs available through CNSF include training workshops, a visitors program, a strategic user program, and NSF sponsored summer institutes. Training and workshops for new and experienced users of the CNSF resources are offered at the Cornell campus and at remote sites on a regular basis. For more information about these programs, consult the Smart Node consultant at UTCC.

Education accounts The CNSF is committed to the training and education of researchers and students in the effective use of advanced computational systems. To achieve that goal, CNSF welcomes applications from instructors who would like to use the supercomputer facility in either undergraduate or graduate course work. For more details, please contact the UTCC Smart Node consultant.

Software list CNSF supports an extensive base of over 300 mathematical, science, and engineering libraries, applications, and graphics packages. A list of software supported by CNSF can be obtained from the Smart Node consultant at UTCC.

National Center for Supercomputing Applications (Illinois)

The current hardware configuration at the National Center for Supercomputing Applications (NCSA), located at the University of Illinois at Urbana-Champaign, includes a CRAY 2S/4-128 with four processors and 128 megawords of central memory; a CRAY Y-MP4/464 with four CRAY Y-MP4/464 processors, 64 megawords of central memory, and a 128 megaword solid-state storage device (SSD); a Connection Machine (Model CM-2) with 32,768 processors, 256 megabytes of memory, 1000 32-bit floating-point accelerators; and a 10-gigabyte DataVault, two frame buffers, and three Sun 4/490 front-end systems; a Convex C3840 with 4 processors and 2 gigabytes of main memory; and six IBM RS6000-550s, each with 128 megabytes of main memory and 1 gigabyte of scratch space. All of these systems have a UNIX-based operating system. An Amdahl 5860 serves as a mass storage system.

Allocations UTCC has joined the Academic Affiliates program at the NCSA. Startup accounts for exploration and training on the CRAY Y-MP are available to the UT community. Requests for larger accounts on the Y-MP or accounts on the CRAY 2 or CM-2 can be submitted to either the National Science Foundation or to the NCSA directly. Applications are available from UTCC.

Special support programs The NCSA has two special emphases, workstation use and visualization. The NCSA encourages their users to use workstations for their development work, then use the supercomputer for actual production work. Workstations can also be used for visualization of data. Visualization allows large amounts of data to be analyzed in a faster, more holistic manner. The NCSA's commitment to visualization also includes the Scientific Visualization Program which provides scientists with the ability to produce videotapes and films of research results. NCSA's Software Development Group has developed software for use with workstations and personal computers including communications packages, image analysis and display tools and presentation tools. This software is in the public domain and available through anonymous FTP, from NCSA or from UTCC. Other support programs available through NCSA include training workshops, a visitors program, a research scientist program, and an NSF sponsored summer institute. For more information, contact the NCSA Affiliate at UTCC, 974-6831.

Software list A wide variety of chemistry, engineering, graphics, and mathematics software is available for scalar, vector, and parallel processing on the NCSA system. A list of software supported by NCSA can be obtained from the affiliate consultant at UTCC.

Pittsburgh Supercomputing Center

The current hardware configuration at the Pittsburgh Supercomputing Center, jointly operated by the University of Pittsburgh, Carnegie Mellon University, and Westinghouse Electric Corporation, includes a CRAY Y-MP/832 and a Connection Machine (CM-2). PSC recently acquired a CM-5 and they plan to replace the Cray Y-MP with a C-90 in October 1992. The CRAY Y-MP/832 consists of eight processors, 32 million 64-bit words of memory, and a 128 million word Solid-state Storage Device (SSD) which can transfer data at 156 Mwords per second. The Y-MP runs under UNICOS, a UNIX-based operating system, with two clustered DEC VAX computers which act as front ends. The VAXes run under ULTRIX and VMS operating systems. The Y-MP has been configured so that it looks like a fast batch queue to front end users, although it is possible to log in directly to the Y-MP. The Connection Machine (CM-2) is a massively parallel 32,768-processor computer from Thinking Machines Corporation. It can be partitioned in quadrants of 8,192 processors, each running a totally different program. Within each partition, each instruction sent to the CM-2 is executed simultaneously by all of its processors. Each processor has a local memory of 32K bytes, making a grand total of one gigabyte of memory on the whole machine. Each processor operates on the data stored in its own memory, but may access the data in the memories of other processors. Driving the CM-2 are two types of front ends: A DEC VAX 6420 and a Sun 4-47 workstation; each runs a UNIX operating system. Connection Machine applications are controlled by processes running on the front ends, which transfer instructions and data to the parallel processing unit of the CM-2. Codes can be distributed between the CRAY and the Connection Machine. Applications using this capability have achieved speedups of between 5 and 10 times compared to using each of the machines separately. The current configuration of the CM-5 includes 256 SPARC processors. Each processor has 16 Megabytes of local memory, and each processor runs at 5 MegaFLOPS, for an overall computational rate of 1.3 GigaFLOPS. This new architecture allows processors working on the same job to carry out different instructions. During late 1992, floating point accelerators will be available which will use vectorization techniques to speed up the SPARC processors to run at 128 MegaFLOPS. This will increase the overall computational rate of the CM-5 to 32 GigaFLOPS. The machine is scalable up to 16,000 such processors. PSC plans to replace the CRAY Y-MP with a C-90 in October, 1992. The C-90 has 16 processors, running at 4 nanoseconds, with an overall rate of 16 GigaFLOPS. It will contain 256 Megawords of memory, a 512-Megaword SSD, and 50 Giagabytes of disk space.

Allocations UTCC is a member of the Pittsburgh Supercomputing Center (PSC) Academic Affiliates program and the Partnership for Academic Consulting and Training (PACT) program. Both are programs for on-campus liaison and support. Researchers who wish to become familiar with the PSC facilities can either apply for computing time directly to PSC or make a request through the PSC affiliate consultant at UTCC. PSC will allocate up to five hours of CRAY processing time without extensive review of the application. Grants for time to support substantive research may be applied for from PSC. The following materials are available from UTCC:

"Applying for a Grant on the CRAY Y-MP/832"
"Applying for a Grant on the Connection Machine"

Special support programs Special support programs available through PSC include training workshops and NSF-sponsored summer institutes. PSC encourages scientists to visit the center in order to use specialized equipment and to get first-hand help from the consulting staff. Through a large grant from the National Institute of Health (NIH), PSC offers workshops to promote supercomputing for biomedical research.

Software list A list of software supported by PSC can be obtained from the affiliate consultant at UTCC.
