            The Scientific Computing  Division  (SCD)  of  the  National
            Center for Atmospheric Research (NCAR) provides supercomput-
            ing resources and services  that  support  research  in  the
            atmospheric,   oceanographic,   and  related  sciences.   We
            emphasize facilities for the development  and  execution  of
            large  models and for the archival and manipulation of large
            datasets.

                 o+    Cray  X-MP/48  supercomputer  running   the   Cray
                      Operating  System  (COS)  with  256  megawords  of
                      solid-state storage.

                 o+    Dicomed graphical film processors capable of  pro-
                      ducing  high-volume  black-and-white microfiche as
                      well as black-and-white or color 16-mm  and  35-mm
                      film.

                 o+    Mass Storage System (MSS) using the IBM 3480  car-
                      tridge  system  associated  with  a disk farm that
                      provides  over  100  gigabytes  of  disk  storage.
                      Currently,  over  10  terabytes of information are
                      archived on the MSS.

                 o+    Xerox 4050 laser printers for text  and  graphical
                      output.

                 o+    A Cray X-MP/18 running the UNICOS  operating  sys-
                      tem.  (Available to users in 1989)

            The Internet Remote Job Entry (IRJE) and the MASnet/Internet
            Gateway  Server  (MIGS)  are  SCD-developed  facilities that
            allow the user to  access  SCD's  computer  resources  while
            using  their  own  local mainframe, workstation, or personal
            computer as a front-end.  The above systems are also  acces-
            sible directly via SCD's IBM 4381 front end computer.

            SCD offers:

                 o+    Consulting expertise on the SCD computing  facili-
                      ties via the Consulting Office.

                 o+    A user area for visiting scientists.

                 o+    Documentation, reference materials,  and  the  SCD
                      Computing News monthly newsletter.

                 o+    Training for users new to SCD's computing environ-
                      ment.

                 o+    Extensive software libraries for use on  the  Cray
                      computers,  such  as  IMSL,  NAG, FISHPAK, SLATEC,
                      ODEPACK, FITPACK, NCAR Graphics, and others.

            NCAR has access  to  several  national  networks  using  the
            TCP/IP protocol, including NSFNET (backbone node) and NASA's
            Science  Network.   NCAR  also  operates  and  manages   the
            TCP/IP-based University Satellite Network (USAN), which pro-
            vides NCAR with high-performance direct links to user sites.
            NCAR has a gateway to Bitnet and SPAN.

            SCD's computing resources are available  to  scientists  and
            researchers  with  NSF  projects in the atmospheric, oceano-
            graphic, and related sciences.  Accounts  must  be  approved
            through  SCD.  Once approved, resources are allocated.  Time
            on the X-MP/18 will be available to government agencies on a
            cost-recovery  basis.   Users with NSF grants should contact
            John Adams, NCAR/SCD, P.O. Box 3000, Boulder CO  90303,  for
            an application form.
