Efficient execution of parallel applications in grid with MPI library

Grid technologies offer powerful computing and storage resources, but the development or adaptation of applications for Grid environments is a difficult task due to the heterogeneity of the resources involved and that these resources need different access control policies. In this paper we present experiments and results for the execution of parallel applications in Grid environments using MPI library. This approach offers high programmability and performances of parallel application, hiding the heterogeneity of the system.
