-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Does anyone have experience writing parallel Java code (using MPI) with calls to C libraries which also use MPI? Is this possible/sensible? Is there a big performance hit relative to doing the same in C++? I'm considering writing some parallel code to do fluid flow in porous media, the heart of which is solving systems of sparse linear equations. There are some good libraries in C which provide the parallel solver (e.g. PETSC), but I'm trying to resolve which language to use for my code. The choice is between C++ and Java, and although I'm favouring Java at present, I'm not sure about its performance in this context.
