Particle physics theoretical and experimental studies

The Advanced Computer Program at Fermilab has developed a multiprocessor system which is easy to use and uniquely cost effective for many high energy physics problems. The system is based on single board computers which cost under $1500 each to build including 2 Mbytes of on board memory. Expansion to 6 Mbytes is now available. These standard VME modules each run experiment reconstruction code in Fortran at speeds approaching that of a VAX 11/780. The first system, now with 100 processors, has been operated for six months, with essentially no down time, by computer operators in the Fermilab Computer Center. An interface from Fastbus to the Branch Bus has been developed for online use which has been tested error free at 20 Mbytes/s for 48 hours. ACP hardware modules are available commercially.
