This paper has firstly analyzed the foundation of parallel-computing,it mainly includes the system structure of the software and the hardware,the programming model,the algorithm and so on, it refers to some new technology in parallel-computing, and also includes some traditional algorithm.We chose MPI as the parallel-computing environment after compared the advantages and disadvantages among MPI、 PVM、OpenMP.Finally,we exec several examples in the parallel Matlab platform ,it shows the high efficiency and conveniency of the parallel-computing.
