Abstract

A new algorithm of two level parallelization for direct simulation Monte Carlo is elaborated for solving unsteady problems of molecular gasdynamics on shared and hybrid memory multiprocessor computers. The first parallelization level (parallel statistically independent runs) is implemented with the aid of MPI library. For the second level (data parallelization) the standard UNIX interprocess communications are employed. Two versions of static load balancing are used for the second level. The study on speedup is carried out by solving one typical test problem of molecular gasdynamics. The computation is performed on shared memory HP/Convex SPP-1600 (8 processors) and hybrid memory PARITET (4 two processor nodes).
