Research on MPI Parallel Programming and Algorithm Implementation in Linux

Parallel computing realizes solving some complex problems. The improving parallel programming technology is applied to a good many domains. MPI is a programmatic model based on message passing and standard that is used widely to write message-passing programs .It is extended to be a good parallel programming language. The basic concepts and methods about parallel programming are introduced briefly. The parallel programming environment and modes of parallel programming of MPI are discussed in detail. The parallelism of MPI is analyzed and the configuring method of MPI programming environment is offered. At last, an instance of implementing a parallel algorithm using MPI is offered. It is easy to implement complex parallel algorithms using MPI in PC Cluster for Linux and better performance Jun be achieved through analyzing the result of experimentation program.
