摘　　要：负载均衡技术是并行计算系统的关键技术之一,其主要思想是将计算任务合理分配到各节点,以避免由于某个节点的计算速度慢而导致的整个系统的性能瓶颈。为了使系统达到更优的结果,提出了一种基于MPICH的负载均衡模型,构建了一个异构Beowulf并行计算系统,并且用一个适合异构环境的矩阵分块相乘算法进行了性能测试。实验结果表明,此算法比使用传统的矩阵相乘算法执行效率更高。从而证明了系统能够把计算任务高效合理地分配到各个节点。Ioad balancing technology is one of the key technologies of the parallel computing system, and its main idea is computing tasks will be assigned to each node reasonably, to avoid the bottleneck of the whole system due to a node of slow. To enable the system to better results, presents an MPICH- based load balancing model of a heterogeneous Beowulf parallel omaputing systems, and with a heterogeneous environment suitable for the block matrix multiplication algorithm was tested. Experimental results show that the algorithm is more efficient than traditional matrix multiplication algorithm implementation. To prove that the system can assign tasks to each nodes reasonably.
