            The Ballistic Research Laboratory (BRL) has a  long  history
            of  participation  in the forefront of computing technology.
            At present, the BRL Super Computing  Facility  includes  two
            High Speed Processors: a Cray X-MP4/8 operating in unclassi-
            fied mode and a Cray-2 operating in classified.   Both  sys-
            tems  utilize  the UNICOS 6.1.12 operating system and imple-
            ment Cray's Network Queing System (NQS) for batch processing
            and Data Migration (DM) software.

            The Cray X-MP/48 has four processors with an 8.5  nanosecond
            clock rate, 8 Million 64-bit words of main memory, and a 128
            Million 64-bit word Solid State Disk (SSD) available to  all
            through  logical  device  caching and swap space.  The clock
            rate enables the machine to operate  in  the  range  of  250
            MFLOPS.   There  are  approximately  40 Gigabytes of on-line
            mass storage, and interfaces to IBM 3480 and IBM  3420  mag-
            netic   tape   devices.    Available  applications  software
            include: DISSPLA;  DISSPOP;  IMSL;  MPGS;  BRLCAD;  PICSURE;
            ABAQUS;   LINDO;   MSC/NASTRAN;  MSC/DYNA;  MSC/PISCES;  and
            LQGALPH. Available compilers include: CFT; CF77; Pascal; and
            C.  The Cray X-MP/48 is available 24 hours per day, 365 days
            per year; however, it is not attended during evening or mid-
            night shifts on weekends or holidays.

            The  Cray-2  has  four  processors  operating  with  a   4.1
            nanosecond  clock rate.  This machine has 256 Million 64-bit

            words of main memory, and operates in the range of 500  Mil-
            lion  Floating  Point Operations per Second (MFLOPS).  There
            are approximately 60 Gigabytes of on-line mass storage,  and
            an interface to IBM 3480 magnetic tape and to a MASSTOR M860
            robotic  tape  device.   Available   applications   software
            include: DISPPLA; DISSPOP; IMSL; MPGS; BRLCAD; PICSURE; CAD-
            PAC; and GAMESS.  Available compilers  include:  CFT;  CF77;
            Pascal;  SIMSCRIPT;  and  C.   The  Cray-2  is available and
            attended 24 hours a day, 7 days a week.

            The Cray X-MP is accessible via the Internet, and has  dial-
            up accessibility.  The Cray-2 occupies a node on the Defense
            Secure Network (DSNET), and has  dial-up  accessibility  via
            Secure Telephone Units (STU-III).
