本文讨论了基于拉普拉斯方程的边界元法的离散化问题。采用快速多极子方法对线性方程组进行压缩。众所周知的并行化标准OpenMP用于共享内存计算机，而新标准Cluster OpenMP用于计算机集群。这两种标准都是基于多线程的，并且非常有效地利用了多核处理器。Cluster OpenMP是OpenMP的增强版。在那里，计算机集群上的多处理被虚拟线程隐藏，虚拟线程使用分布式内存计算机上的虚拟共享内存。
Parallelization of a boundary element method for the solution of problems, which are based on a Laplace equation, is considered. The fast multipole method is applied to compress the belonging linear system of equations. The well-known parallelization standard OpenMP is used on shared memory computers and the new standard Cluster OpenMP is used on computer clusters. Both standards are based on multithreading and exploit multicore processors very efficiently. Cluster OpenMP is an enhancement of OpenMP. There, multiprocessing on a computer cluster is hidden by virtual threads, which use a virtual shared memory on a distributed memory computer.
