Conteúdo: | Parallel programming systems provide the users of parallel computers with a friendly environment in which to develop and run their applications. They achieve this goal by adding an extra software layer between the operating system and the user allowing the latter to write his applications with minimal knowledge of the workings of the machine architecture. In these systems, the distribution of parallel work among the processing units is usually achieved through the implementation of some scheduling algorithm. Efficient scheduling algorithms are essencial when trying to get the best performances out of these systems. In this paper we present a portable parallel programming system, the pSystem, that we have implemented as a testbed to study and compare the performance of various scheduling algorithms on commercial shared memory parallel machines. We describe and give solutions to some difficult issues that were raised when implementing the system. Four scheduling strategy algorithms are presented and their performance evaluated on a set of classical benchmark programs we have written.
