Hi Christopher,

PathScale and CAPS recently announced HMPP as a new manycore GPGPU
open standard and there's a chance you'll see it ported to FBSD. In
addition to this you could see other open standards working well on
FBSD, but that depends on market demand and feedback.
Do we need with this suite a nvidia/ati driver that executes the
CUDA/OpenCL/Stream code? If yes, we'll have the same problem.
I havn't looked deeper into AMDs offerings, but I guess since it's
silent around OpenCL and AMD-based GPGPU, even with Linux there
isn't much.
I'm not very close to the GPGPU scene, we even start thinking about
porting and developing some mathematical stuff into libraries and
thought about OpenCL.
Unluckily, in my team I'm the only one utilizing FreeBSD.
Maybe someone out here has solved some problems and could email me.
Even AMD seems to be a white spot in the subject of GPGPU and
FreeBSD for me, maybe someone could shed some light on this.
What's blocking this from being available now
a) someone porting the kernel driver over or
b) us getting funding to do it.
Perhaps the FreeBSD Foundation can open a new project for it. Today it
can be seen like a "lost-time-addon" for FreeBSD, but not only
Maths/Physics/Chemistry can use GPGPU, it can be used by databases,
compilers, servers, and more in a nearer future. For example, all
algorithms to filter image and video (Scanner, PET, Astronomy, video
de/compression, etc) are being ported to gpgpu and i can't use FreeBSD
for this.
When we started working on the driver months ago one of the main
goals was to allow greater portability. Details for any interested
developers is available any time. In general I'd like to see more
open source OS diversity in the HPC industry and happy to help where
I can.
FreeBSD has better OpenMP capabilities by its network connections,
i'll like to use it in the next HPC era.
For those curious why NVIDIA doesn't port CUDA to FBSD... My guess
is that to do a high quality job it would take 1-2 man years of
effort. In the non-FOSS world that's expensive.
Best,
./Christopher
