[mpich-discuss] MPICH-enabled JWM?

[Mandar Gurav]

Recently, we wrote some compute intensive sample programs both using
C(openmp) and java(Multithreading). And found that the Java programs
took about twice of the time for execution than C. And as compared to
this kind of worst performance the openmp and MPI seem to have good
performance.
