GF11 SUPERCOMPUTER.

Abstract

GF11 is a parallel computer currently under construction at the Yorktown Heights Research Center. The machine incorporates 576 floating-point processors arranged in a modified SIMD architecture. Each processor has space for 2 Mb/s of memory and is capable of 20 MFLOPS, giving the total machine a peak of 1. 125 Gb/s of memory and 11. 52 GFLOPS. The floating-point processors are interconnected by a dynamically reconfigurable nonblocking switching network. At each machine cycle any of 1024 preselected permutations of data can be realized among the processors. The main intended application of GF11 is to a class of calculations arising from quantum chromodynamics, a proposed theory of the elementary particles which participate in nuclear interactions.
