摘要: 本文给出适合寄存器—寄存器加工方式向量机的有效并行直接积分算法。在YH-1机计算表明,当问题总自由度仅为1600阶时,加速比接近30。结合YH-1机特点,在并行计算中部分使用汇编语言,加速比将提高到50。

Abstract: An efficient parallel direct integration algorithm is presented. Computational results for a model in YH-1 computer show that for the model of degree of freedom of 1666, the speed of the parallel algorithm is 30 times faster than of traditional serial algorithm, and if the features of YH-1 computer considered and the assemble language used, it is 50 times faster in the same model case.
