Parallel implementation of a low Mach flow simulator and its performance analysis
Zheng Wang · Kongqi donglixue xuebao · 2002
We parallelized LM_NS3D, a program for three dimensional low mach flow simulation, with PVM as the message passing environment. Communication is carefully optimized. Data locality is achieved. Load balance is considered. Tests done on tow parallel platforms show that the program has a good scalability and a high speedup. Analysis of the results is given. Several routes to improve the performance of parallel programs are discussed. Methods for the parallel implementation for CFD program of this type are summarized.
