I think here it's more a question of compatibility (that is ~ 1.0 / [magnitude of effort]), rather than corporate selfishness >:) Consider memory buffers implementation - counter to CUDA in OpenCL they are some abstract containers, not plain pointers (cl_mem). So, to combine OpenCL with MPI, one first need to propose and adopt suitable API design solution. At least this one is not an easy task, IMO. - D. 2011/10/27 Durga Choudhury <dpcho...@gmail.com>: > Is there any provision/future plans to add OpenCL support as well? > CUDA is an Nvidia-only technology, so it might be a bit limiting in > some cases. > > Best regards > Durga > > > On Thu, Oct 27, 2011 at 2:45 PM, Rolf vandeVaart <rvandeva...@nvidia.com> > wrote: >> Actually, that is not quite right.
