数据并行计算机用于提供内存和减少计算机时间来解决大型有限差分双主问题。有限差分网格被有效地映射到并行计算机的处理器，简单地通过将一个节点映射到一个（虚拟）处理器。在连接机CM-200和CM-5上实现的数据并行有限差分算法允许解决具有超过200万个节点的有限差分bidomain问题。详细的算法一起提出的计算性能结果。
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.
