- The Cornell Theory Center at Cornell University is one of
- four National Advanced Scientific Computing Centers sup-
- ported by the National Science Foundation. The Theory
- Center's resources have been used by more than 5,000
- researchers in fields as diverse as aerospace engineering,
- economics, and epidemiology. Its staff offers technical
- expertise in software, visualization, vectorization, and
- parallel processing to its users, and investigates new,
- highly parallel processing resources for the scientific com-
- munity in order to increase the usability of these computers
- through systems development and through examination of tech-
- niques to improve performance. A variety of education and
- training programs are also offered to high school, undergra-
- duate, and graduate students, and their professors.
-
- The Theory Center, through its Cornell National Supercom-
- puter Facility (CNSF), provides a world-class supercomputing
- environment that includes traditional vector-scalar super-
- computing resources, in addition to scalable, parallel sys-
- tems. Theory Center resources were recently upgraded to
- include a single six-way IBM ES/9000-900 supercomputer (with
- 2.66 Gflops peak aggregate performance, 9 Gbytes shared
- memory). An important feature for many users who now access
- 1 Gbyte of virtual memory is that each user process may
- access up to 2 Gbytes of virtual memory on the ES/9000.
- Parallel resources at the Theory Center include a 32-
- processor KSR1, the 32-processor Parallel Visualization
- Server (PVS) and a Scalable Cluster of RISC Systems. The

-
- KSR1 is a scalable parallel system manufactured by Kendall
- Square Research and offers 1.28 Gflops peak aggregate per-
- formance, and a 1 Gbyte shared memory and 1000 Gbyte address
- space per processor.
-
- The Theory Center is a national center of expertise for
- IBM's PVS and the visual programming interface Data Explorer
- (DX). The PVS is a parallel computer that implements DX
- across 32 processors using a large global memory, and per-
- forming up to 2.5 Gflops. This processing speed combined
- with the portable, user-friendly DX software allows an enor-
- mous range of performance levels with no change in function
- for the user. The same DX is available, for example, on
- the Center's Scalable Cluster of RISC Systems (SCRS), which
- consists of multiple RS/6000 workstations connected via high
- speed networking.
-
- This RISC Cluster is being used for multiprocessing and
- parallel computing. The cluster presently consists of eight
- model 550s, each with at least 128Mb of memory and all run-
- ning AFS (Andrew File System). PVM is available to affect a
- message- passing parallelism. For those with X-capable dev-
- ices, the Center has a PVM workbench to facilitate use of
- the cluster. Express will also be available in the near
- future.
-
- In addition to the production operating environments, full
- support for communications across the NSFNET is provided via
- TCP/IP. Interprocess communications, including remote
- logins, FTP file transfer, and X Window System, are sup-
- ported. FORTRAN is the primary language, and is supported
- in scalar, vector, and parallel modes, with interactive
- debug and execution analysis. Scientific subroutine
- libraries are available, including vectorized and parallel-
- ized versions. Online HELP facilities, UNIX man pages, and
- a Cornell set of TUTOR examples assist users. Graphics
- software supports both local hardware and remote facilities.
- Several well-known application packages and a list of
- software are available upon request.

- The Theory Center's resources can be reached via the Inter-
- net (supporting remote login, file transfer, electronic
- mail, and graphics). Users can access the CNSF via direct
- dialups: 607-255-4141 provides 300, 1200, and 2400 baud
- service; 607-254-5454 provides 9600 baud service.

- All proposals for time on the Theory Center's resources are
- subject to peer review through the Theory Center's National
- Allocations Committee; researchers must submit an applica-
- tion for supercomputer time directly to the Theory Center.

- the Center's Corporate Research Institute may contact Linda
- Callahan at the address and phone number above.
