Hii David, Let me summarise a discussion we (Oliver, Bernd, me) at E@H had on this:
> One API that's always available is OpenGL (and DirectX on Win). We think this assumption may not hold for (near) future or even present day accelerator products, (and accelerators in general are what we should be dealing with): We doubt that NVIDIA Tesla installations (those do not even have video out) or the upcoming Intel Xeon Phi (formerly known as MIC) cards will necessarily support OpenGL or DirectX. Same holds for headless setups in general. > Should we be using these (in addition to, or preferably instead of) > the other APIs, to enumerate GPUs? Probably not instead of, for the reasons given above. Just our 2 cents.
