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 2048 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).
