摘要
对采用多核处理器作为SMP集群系统的计算节点的系统上的一种混合编程模型─MPI+OpenMP混合编程模型进行了深入的研究。建立了两个矩阵乘的混合并行算法,在多核集群平台上与纯MPI算法分别进行了实验,并进行了性能方面的比较。试验表明,混合编程具有更好的性能。
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.
