Re: GPU programming?

Hi Steve
I believe, this is one of the work packages of the Enterprise Working Group. I recommend reaching out to Greg Wallace. He should be able to loop you in, if you're interested in participating in the work.

Subject: Re: GPU programming?

See the second paragraph of my initial post.  AMD provides
ROCm and Nvidia supplies CUDA.  These appear to be available
for Windows and Linux.  Are there any software/hardware drivers
required to actually accomplish the offloading?
