Managing MPI Applications in Grid Environments

摘要

One of the goals of the EU CrossGrid project is to provide a basis for supporting the efficient execution of parallel and interactive applications on Grid environments. CrossGrid jobs typically consist of computationally intensive simulations that are often programmed using a parallel programming model and a parallel programming library (MPI). This paper describes the key components that we have included in our resource management system in order to provide effective and reliable execution of parallel applications on a Grid environment. The general architecture of our resource management system is briefly introduced first and we focus afterwards on the description of the main components of our system. We provide support for executing parallel applications written in MPI either in a single cluster or over multiple clusters.
