The goal of this paper is to determine how e ciently we can implement an adequate parallel programming environment on a workstation cluster without modifying the existing operating system. We have implemented a runtime environment for parallel programs and gang-scheduling on a workstation cluster. In this paper, we report the techniques used to implement gang-scheduling on a workstation cluster...
