Abstract
The success of Grid technologies depends on the ability of libraries and tools to hide the heterogeneous complexity of Grid systems. MPI-based programming libraries can make this environment more accessible to developers with parallel programming skills. In this paper we present MGF, an MPI library which extends the existing MPICH-G2. MGF aims are: to allow parallel MPI applications to be executed on Grids without source code modifications; to give programmers a detailed view of the execution system network topology; to use the most efficient channel available for point-to-point communications and finally, to improve collective operations efficiency introducing a delegation mechanism.
This work has been partially supported by Italian Ministry of Education,University and Research (MIUR) within the activities of the WP9 workpackage “Grid Enabled Scientific Libraries”, part of the MIUR FIRB RBNE01KNFP Grid.it project.
