Reading documentation, thanks b. f. I'm already on freebsd-hackers
list. Is that the correct list for this topic?

Not only compilers for Fortran or other languages but for new
architetures, Cluster of SMP CPUs with GPU attached.

I want to be on that ship, and think that more than only porting
software is needed, live-examples of use, modify the kernel to allow
nvidia/ati (even intel) develop drivers and of course, marketing and
bechmarking (aren't them the samething?)

For now i'm going to port my hpc app to FreeBSD.
