[文摘]:The dramatic improvement in the execution time for the direct simulation Monte Carlo (DSMC) method by the use of parallel processing is demonstrated. Three algorithms are considered: (1) an algorithm in which the collision processes within a cell and the molecular motions are carried out in parallel, resulting in a ninefold reduction in execution time on 32 nodes; (2) an algorithm in which the computational domain is partitioned among the processors so that each processor carries out a distinct but coupled DSMC method calculation on a unique subspace, resulting in a fivefold decrease in execution time on 32 nodes; and (3) an algorithm in which the flowfield is distributed over the processors, but the cell is assigned to a processor based on the amount of time spent calculating collisions in that cell, resulting in a 16-fold decrease in execution time on 32 nodes. (R.R.)
