| Abstract: | A fluid field computation program was parallelized by means of "fluid field decomposition" , and ran successfully in a transputer-based parallel computer, with a parallel efficiency as high as 80%. Field decomposition is based on data parallelization, which has an advantage over program parallelization in that each node program is very similar to the original sequential program. So programming is quite easy. The formulas for speedup and parallel efficiency evaluation are proposed. It is shown that high parallel efficiency can be reached by choosing appropriate computation / communication time ratio. |
