SUPERCOMPUTER SYSTEMS INC. EMPLOYEES ANNOUNCE WORLD'S MOST POWERFUL SUPERCOMPUTER

 EAU CLAIRE, Wis., Feb. 5 /PRNewswire/ -- The employees of Supercomputer Systems, Inc. (SSI) have a shared dream. That dream was to build the "most powerful" supercomputer in the world. In the words of Bill Petefish, one of our head engineers, "We did it! The fastest computer in the world was designed and built in Eau Claire, Wis."
 The SSI machine, dubbed the SS-1, has a balanced, parallel, scalable systems architecture managed by an advanced parallel, vector and scalar optimizing compiler in a standard UNIX operating system. A unique characteristic of the SS-1 is its integrated parallel hardware, OS and compilers in a single architecture that is scalable from small to highly and massively parallel applications without major user software reinvestment. The well balanced design of the SS-1 and its superior sustained performance makes it a market leader in the general purpose, large scale production and research user environments.
 In his announcement to employees that SSI would be closing, Dr. Steve Chen, president and CEO of SSI, revealed that prior to being taken off line several benchmarks were run under the operating system at 2.5 nanoseconds achieving the world's highest performance for a single processor. The technology development successes achieved by both SSI and IBM in this partnership has produced a general purpose parallel architecture and system making possible the successful convergence of classical vector supercomputing and the massively parallel architecture proliferating in the country today.
 The SS-1 is a 32-CPU, shared memory system featuring 64-bit IEEE arithmetic, ultra high-performance I/O, and standard network capabilities. The system operates under SSI's multi-threaded, multi- task standard UNIX operating system and parallel optimizing Fortran and C compilers. The system is well balanced with greater than 50 gigabytes per second of I/O bandwith and maximum memory bandwidth greater than 400 gigabytes per second. The SS-1 architecture design also accommodates multi-system clustering with 128 CPU or more for solving a single large application. The SS-1 has a peak performance of 51.2 Gflops (billions floating point operations per second), expandable to more than 200 Gflops with clustering.
 In standard industry benchmarks, the SS-1 achieved greater than 48 Mflops (millions of floating point operations per second) harmonic mean on the Livermore Loops. The SS-1 machine has already demonstrated close to 400 Mflops on the Linpack 100x100 single processor performance with our compiler; it is estimated that production models will perform at speeds greater than 640 Mflops.
 With a 2-CPU machine working now, SSI anticipated shipping its first production models in November 1993.
