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.
Corporations interested in using the Theory Center through
the Center's Corporate Research Institute may contact Linda
Callahan at the address and phone number above.
