External Email - Use Caution
Hi Richard,
That is a very good point. I knew it was being deprecated and there was talk of OpenCL but I have not been keeping up. Multicore systems were getting the most benefit from newer releases. Certainly, to run the existing CUDA code involved making sure your sysadmin would give you the older CUDA libs too.
Thank you for your input. I know it was a long time ago but I remember your GTC presentation for sure.
Cheers,
-Morgan

External Email - Use CautionSorry I'm coming to this a bit late.... I'm not sure that the CUDA implementation is supported these days. I've not done much work on em_ and ca_register since 2012; I'm not sure about the surface stream (I didn't do that port). Furthermore, I don't see CUDA being included in the new CMake build system. Some differences to the CPU stream are inevitable (floating point arithmetic and all that), but if the workflow in those binaries has changed since when I was working on them, then those changes may not be reflected in the GPU code.

Richard
