The GF11 supercomputer

Abstract

GFI I is a parallel computer currently under construction at the Yorktown Research Center. The machine incorporates 576 floating-point processors arranged in a modified SIMD architecture. Each processor has space for 2 Mbytes of memory and is capable of 20 MFLOPS, giving the total machine a peak of 1.125 Gbytes of memory and 11.52 GFLOPS. The floating-point processors are interconnected by a dynamically reconfigurable non-blocking switching network. At each machine cycle any of 1024 pre-selected permutations of data can be realized among the processors. The
