Workload decomposition strategies for shared memory parallel systems with openMP

摘要

A crucial issue in parallel programming (both for distributed and shared memory architectures) is work decomposition. Work decomposition task can be accomplished without large Programming effort with use of high-level parallel program- Ming languages, such as OpenMP. Anyway particular care Must still be payed on achieving performance goals. In this Paper we introduce and compare two decomposition strate- gies, in the framework of shared memory systems, as applied To a case study particle in cell application.
