PVMWebCluster: Integration of PVM Clusters Using Web Services and CORBA

We propose a new architecture and its implementation called PVMWebCluster which enables easy parallelization of PVM task execution both onto geographically distributed PVM clusters and within them. Task submission is done by calling Web services that negotiate the best cluster(s) for the task and communicate with clusters via CORBA method invocation. PVMWebCluster supports tightly-coupled high performance demanding parallel applications by using PVM/DAMPVM, implements the idea of controlled cluster sharing among users as in grids and multi-tier applications and finally integrates the components using the latest Web services approach. This architecture gives flexibility, easy access for many users through simple code from many languages and operating systems and future development possibilities. We have implemented a testbed application and evaluated it on a testbed platform consisting of four clusters and eight nodes. Multiple copies have been run on the clusters and also parallelized within each of them using DAMPVM also implemented by the author.
