Towards a portable cluster computing environment supporting single system image

Cluster computing environments, e.g. DSE, NOW, created out of commodity-off-the-shelf computer and networking hardware have gained wide popularity as a cost-effective solution to high performance computing. Considering the recent trends in cluster computing technology and for practical usability, the need to provide a single-system image is important where users can freely use these cluster computing systems without knowing the underlying system architecture. We cite some related works and present our approach. We describe the modified software organization of DSE, discuss the experiments and results of parallel applications on different UNIX-based platforms. Finally, we give our concluding remarks and future directions.
