Oppss, i missed an 'I', i want to say OpenMPI, which is already in

With the 3rd party vendor closed source tools little can be done if
they are not convinced about the freebsd market capabilities. With the
open source ones, some of them are already ported to freebsd or don't
need a port to work, but you are right, in this "league" we go behind.

For the HPC compiler, gcc is still the main compiler and OpenMP
(without the I ;)) is supported since version 4.2 if i remember
correctly but i haven't tried it under FreeBSD only in Linux. Open-MPI
is in ports too.

Don't know the status of Infiniband drivers, are there drivers?

Yes, but the freebsd community must develop it before a it can be
delivered. There's a HPC mailing list, completly abandoned, only spam.
There isn't a directory on ports with hpc programs neither.

I'll ask these administrative questions on other mail thread on this
