Proposal status
MPIService has been available in Ccaffeine (in the ccaffeine package scope) since 1999. Two other implementations are now also available.
There are three implementations of proposed port MPIService:
MPIService in ccaffeine, by Ben Allan. (see cca-forum.sourceforge.net)
MPIService as a stand-alone, bocca-generated component available from the tutorial repository. (see cca-forum.sourceforge.net)
MPIService in Scijump by Kosta Damevski.
Pending an endorsement by CCARB, MPIService is ready to vote.
There is one (component) implementation of MPISetup, a port allowing reuse of the same service in communication agnostic frameworks such as decaf and ccaffeine (when not configured with built-in mpi support). The working group does not propose (or see the need to propose) making MPISetup a part of the CCA specification interfaces.
