Abstract

In this paper, a data-parallel computer is used to provide the memory and reduction in computer time for solving large finite-difference bidomain problems. The finite-difference grid is mapped effectively to the processors of the parallel computer, simply by mapping one node to one (virtual) processor. Implemented on the connection machines (CM's) CM-200 and CM-5, the data-parallel finite-difference algorithm has allowed the solution of finite-difference bidomain problems with over 2 million nodes. Details on the algorithm are presented together with computational performance results.

摘要

在本文中，使用数据并行计算机来提供内存并减少求解大型有限差分双域问题的计算时间。通过将一个节点映射到一个（虚拟）处理器，有限差分网格被有效地映射到并行计算机的处理器上。在连接机（CM）CM - 200和CM - 5上实现的数据并行有限差分算法，使得能够求解节点数超过200万的有限差分双域问题。文中给出了算法的详细信息以及计算性能结果。
