Abstract

Ensemble-1 has been proposed for composing applications, consisting of MPI based components and external composition directives. Composed applications may be executed on any MPI distribution. Ensemble-1 followed the “static” principles of MPI-1; there is no dynamic process creation or destruction. In this paper, we propose Ensemble-2 supporting the composition of dynamically created processes following MPI-2 standard. The composition is based on construction of intercommunicators and establishing communication channels using either the parent/child or the client/server process relationship model.
