Nowadays, the applications of MPI-based clusters are used widely, such as the damage prediction of nuclear explosion and gene decryption. However, the usages of MPIbased heterogeneous cluster are nearly reported in contrast to the MPI-based homogeneous clusters due to the immature technology. This paper focuses on building a MPI based heterogeneous cluster with the MPICH2, which is released last year and has not supported the heterogeneous cluster yet. Beside, we give the reasons and test results in the paper to illustrate the benefits of using the MPI-based heterogeneous cluster without virtualization.
