Abstract
A parallelization study of Quantum Chromodynamics (QCD) simulation on a non-dedicated MIMD computer, Fujitsu AP1000, is reported, The AP1000 is a highly parallel computer with distributed memory, Data communica tion is fast not only among the nearest neighbor processing units, but also between widely separated ones, We study SU(3) quenched QCD simul ation with lattice sizes of 32(4) and 32(3) x 48, on the 512-processor AP1000, and report parallelization techniques and physical results fo r a renormalization group study and hadron spectroscopy, The AP1000 is efficient for these QCD simulations and shows good performance. A bot tleneck occurs in the current simulation as data is passed to the fron t-end processor for storage.
