PVM Performance Optimum and Experiment Analysis Based on Task Control and Message Routing
Yu Liu · Journal of Guilin University of Technology · 2010
PVM is one of the most popular parallel programming environments.But the default setting of PVM system is not the best in some specific cases.Matrix multiplication is one of the most typical operations in the fields of computing parallelization.By testing the example of matrix multiplication on PVM platform,this paper provides the test data of PVM performance improvement under different task division,message package/route and task distribution conditions.It is suggested that PVM task granularity should match the scale of cluster.Choosing message package/route strategy properly can improve communication performance.Increasing the effective running time of each node is the key to improve the performance of PVM.
