| 摘 要： | 本文旨在讨论ＧＰＣ算法［１，２］的并行化问题，通过对原串行算法的数据流及数据相关性的分析，得到了一种三角阵列的并行算法。该算法自然导致Ｓｙｓｔｏｌｉｃ结构，并具有良好的数值稳定性。对于一个 ｎ阶系统而言，本算法采用Ｏ（ｎ２）阶的处理器单元互连成三角阵列，可以把计算时间由原来的Ｏ（ｎ３）阶（内积运算）时间提高到 Ｏ（ｎ）阶，因而具有 Ｏ（ｎ２）的加速比，其处理器的利用效率得到了很大提高。

| Abstract: | In this paper, the parallel problem of GPC algorithm is discussed. By analyzing of the data flow and data correlation of the original string algorithm, we obtain a parallel algorithm of tringular matrix sequences. The algorithm results in the systolic structure, and it has excellent numerical stability. For a system of degree n, the algorithm uses the processor unit of degree O(n2) to link tringular matrix sequence. The computation time was decreased from O(n3) to O(n). So it has accelerated proportion of O(n2). The efficiency of the processor has increased greatly. |
