            The Cornell Theory Center-with  support  from  the  National
            Science  Foundation, IBM Corporation, the State of New York,
            and members of  its  Corporate  Research  Institute-provides
            supercomputing  resources  for  researchers nationwide.  The
            Center's resources include two IBM ES/3090 600J supercomput-
            ers,  staff,  and  related  programs that explore the use of
            experimental parallel architectures.

            Nearly four  thousand  researchers  (including  three  Nobel
            Prize  winners,  fourteen members of the National Academy of
            Science,  and  ten  members  of  the  National  Academy   of
            Engineering)  have  used  the Center's facilities to work on
            more than eight hundred research projects.  This  work,  led
            primarily  by  university  faculty  at more than one hundred
            fifty institutions, represents  a  diversity  of  scientific
            disciplines, from the physical to social sciences.

            The Center's two IBM ES/3090  600Js  each  have  six  vector
            facilities  and a peak performance of 827.6 megaflops.  Each
            has 512 megabytes of memory  and  2  gigabytes  of  expanded
            storage.   The total disk storage capacity is 266 gigabytes.
            The principle operating  system  on  the  supercomputers  is
            IBM's  implementation  of  UNIX, AIX.  Each user application
            may access up to 896 megabytes in AIX.   There  is  software
            support  for vectorization, including a vectorizing compiler
            and vector libraries.  Both interactive and batch modes  are
            provided  in  the  Center's  production environments.  Users
            interested in using parallel computing for their  production

            work are strongly encourged  to  consider  applying  to  the
            Strategic User Program.

            In addition to the production operating  environments,  full
            support  for  communications across the Internet 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; it is supported in
            scalar,  vector,  and parallel modes, with interactive debug
            and execution analysis.  A high-performance  C  compiler  is
            also  available.  Scientific subroutine libraries are avail-
            able, including vectorized versions.   Online  HELP  facili-
            ties,  UNIX  man  pages, and a Cornell set of TUTOR examples
            assist  users.   Graphics  software  supports   both   local
            hardware and remote facilities.  Several well-known applica-
            tion packages and a list  of  software  are  available  upon
            request.

            At Cornell, interactive  graphics  devices  include  TCP/IP-
            attached  workstations.   Hardcopy devices include videotape
            production,  35mm   slides,   plotters,   color   PostScript
            printers,  and X Window System screen-dump printers.  Remote
            researchers can use X Window System screen utilities or Tek-
            tronix  emulation to view images.  Remote users can also ftp
            various types of image files and metafiles to themselves for
            viewing  with  their  own  software.  Graphics software sup-
            ported on the supercomputers includes WaveFront and X Window
            System  in  AIX.  X Window System utilities include xim with
            WaveFront and volume-renderer  interfaces,  gnuPLOT,  and  a
            version of xmovie.

            Theory Center resources can be reached via NYSERNet, NSFNET,
            and associated regionals such as SURANet or Milnet (support-
            ing remote  login,  file  transfer,  and  electronic  mail),
            either  directly or through a Sun front-end running Berkeley
            UNIX.  The Theory Center provides file  transfer  and  batch
            job  submission through BITNET.  Terminal traffic may access
            Theory Center via direct dial-ups.

            All proposals for time on Theory Center resources  are  sub-
            ject  to  peer  review through the Center's National Alloca-
            tions Committee.  Researchers must submit an application for
            supercomputer  time directly to Pat Colasurdo, User Accounts
            Coordinator, at the address and phone number above.
