            The Center for Experimental Research in Parallel Algorithms,
            Software  and  Systems  (CERPASS)  provides  an experimental
            facility for researchers on the Internet.

            The Center's parallel computing resource includes a  Connec-
            tion Machine CM-2 and a Symult Series 2010.

            The Connection Machine Model CM-2 is  a  massively  parallel
            SIMD  machine.  Its hardware consists of 16,384 data proces-
            sors interconnected via a hypercube network.  Each processor
            has  a bit-serial ALU and a 64K-bit local memory.  This CM-2
            has two front-end subsystems -- one VAX 6210 and one Symbol-
            ics  3600,  a  5-Gigabyte  mass storage system and a graphic
            color display device.  Half of the machine (i.e., 8,192 pro-
            cessors)  is  also equipped with floating-point accelerator.
            Programming languages  available  on  this  machine  include
            *Lisp, C* and Paris interfaces to Commonlisp and C.

            The Symult S2010 is a  message-passing,  distributed  memory
            MIMD  machine.   Its  hardware  consists of 32 computational
            nodes. Each node has a 32-bit Motorola 68020  microprocessor
            as  its  CPU, augmented by the Motorola 68881 floating-point
            coprocessors.  Each node has 8MB local memory, and  is  con-
            nected  with  other  nodes  via a high-speed message-routing

            Both the CM-2 and the Symult  S2010  can  be  accessed  from
            Internet via their VAX and SUN front-ends, respectively.
