Dynamic Interoperable Message Passing

摘要

In this paper we present two solutions to dynamic interoperable MPI communication. These solutions use the Inter-Cluster Interface library that we have developed. The first solution relies on the MPI-2 Standard; specifically on general requests, threads and "external32" encoding. The second solution discusses adjustments to the first solution that allow its implementation in environments where some parts of the MPI-2 Standard are not implemented, and can even work independently of MPI. We have successfully implemented these solutions in a number of scenarios, including parallelizing SAT solvers, with good speedup results.
