Abstract :
To improve the total performance of a PC cluster or a supercomputer with multi-core scalar CPU, not only parallel efficiency among computational nodes or CPUs, but also efficient utilization of processor cores of CPU are becoming more important than ever before. In this paper, we implement the BDD method by three kinds of programming styles to evaluate parallel performance on a multi-core CPU node. We demonstrate some numerical examples using a multi-core CPU. Especially, by changing the design from memory access intensive approach to matrix storage-free one, the parallel performance is improved.
