P2P-MPI is developed by the ICPS group part of the LSIIT laboratory (University of Strasbourg and CNRS). The project has also benefited from support from INRIA.
The standard Message Passing Interface specification has no bindings for Java, but the HP Java project proposes an mpiJava API (local copy). P2P-MPI API tries to follow closely this proposal and currently provides a subset of this API.
