| Abstract: | This paper proposes using multi-core processor as a computing node in the SMP cluster system,and studies the MPI+OpenMP hybrid programming model which is suitable for this system.To compare the performances of hybrid programming model and the pure MPI algorithm,two different matrix multiplication algorithms on both models are designed and tested in laboratory.The results show that the hybrid programming model can provide better performance. |
