Early implementation of Para++ with MPI-2

Abstract

Gives an overview of the implementation of Para++'s dynamic process management on top of an early MPI-2 implementation. It is currently implemented on top of LAM 6.0. After a presentation of the Para++ concepts, a presentation of the internal implementation of Para++ on top of both PVM and MPI-2 is made. This implementation uses the dynamic process chapter of MPI-2, and makes intensive use of the inter-communicator operations. The highlights given in this paper should help people to better understand how Para++ 2.0 works as well as giving an exhaustive example of an MPI-2 application.
