I was just wondering how to use MPI with g95. I have 3 old I386
computers connected via 100mbps ethernet, and I was going to see if I
could run an MPI program. Can I use Windows 2k or do I need to use a
linux distribution? I also have access to 3 computers with SPARC
processors. Can these be used together with the I386's? Any help is
greatly appreciated.
windows, g95 and mpi should be fine, I use g95 with mpich2 on an XP
laptop and that seems to work well. sparc + i386 may be more tricky,
never tried that. I vagely remember seeing that e.g. LAM MPI has the
restriction that the data types must be of the same size, which could
give you trouble since your SPARC is probably 64bit, while i386 is
32bit. I guess you will need to use MPI of the same brand across the
machines. MPICH or LAM are good implementations.
