We propose a grid programming approach using the ProActive middleware. The proposed strategy addresses several grid concerns, which we have classified into three categories. I. Grid Infrastructure which handles the resource acquisition and creation using deployment descriptors and Peer-to-Peer. II. Grid Technical Services which can provide non-functional transparent services like: fault tolerance, load balancing, and file transfer. III. Grid Higher Level programming with: group communication and hierarchical components. We have validated our approach with several grid programming experiences running applications on heterogeneous Grid resource using more than 1000 CPUs.
This paper argues that algorithmic skeletons are a suitable programming model for multi-core architectures. The high-level abstractions offered by algorithmic skeletons provide a simple way for non-parallel programmers to address parallel programming.Previous algorithmic skeleton frameworks and libraries have addressed distributed computing environments such as Clusters and Grids. This paper proposes a parallel skeleton library, Skandium; and concludes, after an experimental evaluation, that algorithmic skeletons are an effective methodology to program multi-core architectures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
