TASK SCHEDULING FACILITY FOR PVM
Bu‐Sung Lee, A. Heng, Wentong Cai, Tai-Ann Tan · Parallel Processing Letters · 1996
Whilst the concept of a virtual metacomputer over a networked collection of heterogeneous computer systems has slowly emerged. there are still some shortcomings of these systems. For example. some systems are still incapable of balancing the load amongst the workstations; the problem is accentuated by the heterogeneity of the computers. In this paper. we first discuss the design issue of our centralized task scheduler. and then present our implementation details. To use the task scheduler. some new library routines are provided. The task scheduler is layered above PVM; this has the advantage of retaining its portability. Since load-balancing is considered in task scheduling. our approach has been also proven to be more effective than the existing PVM round-robin task allocation scheme.
