Well, 32-Bit isn't realistic in a scientific environment! There are some
'tricks' and 'tweaks' out making CUDA working on FreeBSD with Linux
binaries, but, simply for instance, portions of our computing system
rely on OpenLDAP and I do have severe problems making OpenLDAP
authorised users available to some IDL applications running on FreeBSD
boxes within the linuxulator. This is only one small but very effective
trap one can step into.
There are some other, very serious questions. AMD calims that they made
the specs of their 3D chipset internals public. There is OpenCL as an
open standard, there is the CLANG/LLVM project even for FreeBSD to
become the new standard compiler and, not at last, there is work done on
drivers for AMD graphics boards but there is no, not even rudimentary,
support for GPGPU. I preferr a clean open source solution, but at the
moment, it seems to be the best and easiest path to switch to an
operating system that is fully supported, even 64 bit.
