An Improvement Method of MPI Parallel Program Performance Optimization
Xin Nie · Modern Computer · 2011
MPI is an ideal parallel programming model,which has been confirmed on distributed storage system.Because MPI is based on message passing and adopts the method of message passing to realize the communication between every node,the performance of MPI parallel program is deeply depended on the efficiency of communication.By using the cluster communication to replace the peer to peer communication function and using the derived datatype to create new communication domain,puts forward a common method of optimizing MPI parallel program via the experiment on improving on the MPI parallel program of DNS twice and advancing the performance of it.
