Abstract

This article presents an evolution of classical SPMD programming for clusters and grids. It is named "object-oriented SPMD" as it is based on remote method invocation. More precisely, it is based on an active object pattern, extended as a typed group of active objects, to which SPMD's specificities are added. The proposed programming model is more flexible: techniques to postpone barrier and to remove any explicit loop make it possible to privilege reactivity and reuse. The resulting OO-SPMD API has been implemented in ProActive. Good scalability and quite competitive performances, compared to what is obtained using C-MPI, are demonstrated.
