MGF: A grid-enabled MPI library with a delegation mechanism to improve collective operations

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. © Springer-Verlag Berlin Heidelberg 2005.
