Summary

This paper describes the ACPMAPS computing system -- its purpose, its hardware architecture, how the system is used, and relevant programming paradigms and concepts. Features of the hardware and software will be discussed in some detail, both quantitative and qualitative. This should give some perspective as to the suitability of the ACPMAPS system for various classes of applications, and as to where this system stands in the spectrum of today's supercomputers. The ACPMAPS project at Fermilab was initiated in 1987 as a collaborations between the Advanced Computer Program (now the Computer R D department) and the lattice gauge physicists in the Theory department. ACPMAPS is an acronym for Advanced Computer Program Multiple Array Processor System -- this acronym is no longer accurate, but the name has stuck. Although research physics computations were done on ACPMAPS as early as 1989, the full-scale system was commissioned as a reliable physics tool in early 1991. The original ACPMAPS was a 5 Gflop (peak) system. An upgrade by a factor of ten in computer power and memory size, but substituting a new CPU board, will occur during early 1991 -- this is referred to as the new ACPMAPS Upgrade or 50 GF ACPMAPS. The appellation ACPMAPS II has also been applied to the upgrade; this is somewhat of a misnomer, since only one of five major components was changed.
