h8E6dqt5lkL9o The parallel algorithms were executed on the Connection Machine model CM-2 --- a single-instruction multiple data (SIMD) parallel computer which, in its largest configuration, contains 65,536 bit-serial processors and 20 Weitek floating-point units (FPU's). The bit-serial processors are clustered together into groups of 16 within a single integrated circuit, and these IC's are connected together in a 12-dimensional hypercube. Two IC's, or 32 processors, share a single Weitek FPU. Note that a fully configured CM-2 contains 2048 times as much floating point hardware as a conventional computer containing a single Weitek FPU (e.g., a SUN-4).
