            The Pittsburgh  Supercomputing  Center  (PSC),  one  of  the
            national centers established by the National Science Founda-
            tion,  provides  advanced  supercomputer  resources  to  the
            scientific  and  engineering  research communities. PSC pro-
            vides computing resources and support facilities for work in
            many  branches of science. To date, it has supported work by
            over 1900 researchers at 375 institutions in 49 states,  and
            the  District of Columbia, representing virtually all fields
            of scientific and engineering endeavor.

            The Center currently offers:

               o+  a Cray Y-MP/832  supercomputer  which  features  eight
                  processing  units  sharing common memory of 32 million
                  64-bit words

               o+  a Solid-state Storage Device (SSD) which will hold 128
                  million  words and can transfer data at 156 Mwords per
                  second on each of two parallel channels

               o+  an IBM 4381-P21 with 30GB of disk storage for CFS,  an
                  archiving system

               o+  a Connection Machine CM-2, with 32,768 processors  and
                  one gigabyte of memory

               o+  a DataVault with 10 gigabytes of high speed storage

               o+  a Digital Equipment Corporation VAX,  CMVAX,  and  two
                  SUN  4470s, SUNA and SUNB, running Ultrix and Unix, as
                  front ends to the CM-2

               o+  two Digital Equipment Corporation VAXes running VMS as
                  front ends to the Y-MP, CMVAX and SUNs

               o+  two Digital Equipment Corporation VAXes running Ultrix
                  as front ends to the Y-MP, CMVAX, and SUNs

               o+  the Andrew File System,  a  distributed  network  file
                  system, serving the Ultrix front ends and the CM front
                  ends

               o+  high-function engineering workstations, personal  com-
                  puters,  and special-purpose graphics devices, such as
                  a Silicon Graphics IRIS workstation, SUN Sparcstation,
                  IBM   RS6000,  DECStation  5000,  Canon  CLC500  color
                  copier/printer, and Postscript laser printers, and

               o+  CGM-based animation system producing VHS tape and  and
                  videodisk animations, plus the ability to produce 35mm
                  color slides using a Matrix Instruments SlideWriter.

            The Center provides experienced user services  and  training
            in  scientific research. Consultants are available to answer
            users' questions Monday through Saturday. The Center  offers
            classes  and  workshops on different aspects of supercomput-
            ing, provides online and hardcopy documentation, produces  a
            monthly  newsletter  and  a technical bulletin, and annually
            publishes a booklet which highlights some of the  scientific
            research  done at the Center. The systems and software staff
            selects and installs  new  software  and  spearheads  system
            development efforts.
