Abstract
The increasing popularity of a Cluster of Workstations (COW) for the execution of parallel applications can be attributed to its impressive price to performance ratio. Unfortunately, currently available software to manage the execution of parallel applications on COWs do not provide satisfactory levels of performance, nor do they provide the application developer with a friendly programming environment. This final problem can be attributed to the lack of transparency provided by these systems when managing distributed resources such as parallel processes, processors and memory. This paper presents a unique process instantiation approach that addresses the shortfalls in currently available SPMD parallelism management systems for COWs by employing a combination of process duplication, process migration and group communication services; all built on and supported by a distributed operating system.
