Have you tested this first hand?
Is there 32bit Fermi? (Sorry, but I don't think the HPC world can
really live off 32bit applications)
There's 2 types of code in a "cuda application" there's host code
produced by the native compiler (gcc/intel/pathscale.. etc) and the
device code.. produced by nvidia's toolchain.. I would make a pretty
nice bet that the nvidia userland toolchain will not compile code on
freebsd right now.. (not be negative here, but I'm intimately familiar
with it..) Worse case you'd be copying code built on linux over and
also the runtime libs.. (not to mention debugger, profiler. etc)
Anyway.. as mentioned before we'll have a native working solution before
the years end and anyone interested to help alpha/beta test is welcome
to contact me offlist..
