does red hat 5.0 support MPI


I would like to know if there is a command or any other method to check if my platform (red hat 5.0) supports MPI based parallelization. Please advise.

Thank you

It is for the kernel to support MPI. .. Many distros are available for parallel computing/programming and clustering. Use them.

Rock Cluster Linux, etc

You can use RHEL or clones, but it will be better to compile a new kernel in them.

I don't think that's true. I think you need the kernel to support multiple processors and need to install an MPI implementation (like Open MPI).

Is there a way I can verify if the kernal already supports an MPI implementation such as Open MPI?? Thanks for your suggestions

Again, it's not the kernel that needs to support MPI. I'm not sure of the best way to check whether you've got an MPI implementation installed, but one way would be to do a "locate mpi.h" and see what that gives you. On the systems I use for my work, we've got MPICH installed and doing "locate mpi.h" gives me the following:

/opt/mpich/include/mpi.h
/usr/include/dfftw_mpi.h
/usr/include/drfftw_mpi.h
/usr/include/H5FDmpi.h
/usr/include/sfftw_mpi.h
/usr/include/srfftw_mpi.h
/usr/lib/gcc/i586-suse-linux/4.1.2/include/jvmpi.h
/usr/lib/jvm/java-1.5.0-sun-1.5.0_update14/include/jvmpi.h
/usr/src/linux-2.6.18.8-0.9/drivers/message/fusion/lsi/mpi.h

You could of course just ask your system administrator, though.

Thanks for your suggestions. I typed "locate mpi.h" and found that I have a hp-mpi implmentation installed.
