Reading documentation, thanks b. f. I'm already on freebsd-hackers list. Is that the correct list for this topic? >=20 > >> 2) HPC ready compiler..

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. >=20 > b. Thanks
