OCaml and GPUs

OCaml and GPUs

Hello,

I was wondering if there has been any effort so far in interfacing OCaml
with GPU programming solutions like AMD Stream, or OpenCL.
I'm only aware of Daml (CUDA bindings).

I wrote some pieces of AMD Brook bindings a while ago to do very basic
read/write operations on GPU, plus some kernel calls.
I don't have much time to invest in this unfortunately.
With OpenCL's ability to compile kernels at runtime, bindings for Ocaml
could even offer the nice possibility to write the kernels in .ml files as
strings, which would save a lot of wrappers around kernel-only C files.

any ideas, comments, pointers ?

Guillaume.

Not aware of any other bindings. I think I got daml to a stage similar to your 
Brook bindings where you could allocate a floating point array in the gpu and 
then maybe do something with that array. I can't really remember. It's been a 
while since I looked at it.

I would have expected CUDA to have a similar ability but haven't checked.
