Implementation of Gang-Scheduling on Workstation Cluster

The goal of this paper is to determine how efficiently 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 an efficient runtime environment and gangscheduling on a workstation cluster. The most important technique is “network preemption.” A unique feature of our approach is that the gang-scheduling is also written in a parallel language. Our evaluation shows that gang-scheduling on workstation clusters can be practical.
