MPI is a standard MPICH implement MPI as much as possible it is also the testbed used for MPI normalisation. today it support MPI1.1 and some MPI2 extensions. >The basic MPI commands, I believe, should stay >the same - only the implementation and execution of the files should differ. MPI command are note part of the standard. only language mapping and operation behavior is normalised. >Any thoughts/advise is appreciated. Look at the MPI FAQ, or even the MPI site. it must be referenced here in the periodic FAQ message of this group.
