Enabling JaSkel skeletons for clusters and computational Grids

JaSkel is a skeleton-based framework to develop efficient concurrent, parallel and Grid applications. It provides a set of Java abstract classes that implement recurring parallel interaction paradigms. The key feature of JaSkel is to use aspect-oriented external tools to address distributed execution, by injecting code to support communication middleware into JaSkel built-in skeleton implementations. This feature, when combined with the ability to develop nested skeletons, can help to tailor JaSkel applications to efficiently run on a grid of clusters systems, by taking advantage of inter/intra-cluster and/or intra-node communications. This paper describes the JaSkel distributed execution tools and how they interplay with the JaSkel framework to transparently run applications on a wide range of computing platforms, from multi-core to computational grids. Results are presented to show the feasibility and scalability of this approach.
