            The  Center  for  Theory  and  Simulation  in  Science   and
            Engineering   at  Cornell  University  (Theory  Center),  in
            cooperation with the National Science Foundation,  IBM  Cor-
            poration, and the State of New York, provides supercomputing
            resources for researchers nationwide.

            The Center's primary supercomputing  resource,  the  Cornell
            National  Supercomputer Facility (CNSF), consists of two IBM
            3090-600Es with 12 processors and attached  minisupercomput-
            ers,  giving  a  peak throughput of over 1.5 gigaflops.  All
            systems fully support  ANSI-standard  Fortran-77.  Each  IBM
            3090-600E has six vector facilities and gives a peak perfor-
            mance of 696 megaflops.  Each has 256  megabytes  of  memory
            and  1  gigabyte  of expanded storage.  Some 75 gigabytes of
            disk storage in total are available for users.  Each  appli-
            cation may use up to 1 gigabyte of virtual memory.  There is
            software  support  for  parallelization  and  vectorization,
            including  a  vectorizing  compiler  and  vector  libraries.
            VM/XA SP (CMS) is the operating system; both interactive and
            batch  modes  are  provided and parallel work can be done in
            either mode.

            The full set of operating system functions and utilities  is
            available  for  interactive  and batch jobs.  Communications
            are supported for a variety of dial-up terminals and  TCP/IP
            networks.  FORTRAN is the primary language, and is supported

            in scalar, vector and parallel mode, with interactive  debug
            and  execution analysis. Scientific subroutine libraries are
            available, including some vectorized versions.  HELP facili-
            ties  and  a  Cornell set of TUTOR examples assist the user.
            There is extensive host support for the attached  minisuper-
            computers.   Graphics  software supports both local hardware
            and remote facilities.  A number of well  known  application
            packages  are  available,  as  well as a public disk of user
            contributed packages.  A list of software is available  upon
            request.

            There are several graphics facilities located on the Cornell
            campus,  connected to the CNSF via a high-speed channel run-
            ning over a fiber optic link.  Each facility contains a wide
            range  of  graphics  hardware,  including  sophisticated IBM
            graphics workstations, various UNIX  (a  trademark  of  AT&T
            Bell  Labs)  workstations, printers, and plotters.  The cen-
            tral facility has equipment to allow researchers to  produce
            computer-generated  animation,  either  on  16mm  film or on
            video tape.

            The CNSF can be reached via NYSERNet, NSFNet, and associated
            regionals  such  as  SURANet,  Arpanet,  Milnet  (supporting
            remote login, file transfer, and mail), either  directly  or
            through  a  Gould  frontend running Berkeley UNIX.  The CNSF
            provides file transfer and batch job submission through Bit-
            net.  Terminal traffic may access CNSF via direct dial-ups.
