Update:
Larrabee?? Several $billion of Intel R&D and they scrapped it ... Meanwhile, back at WCG we've had a few intial beta test runs of GPU for HCC, but it's a while since the last one. Obviously lots of problems. |

OpenCL is the wave of the future for GPU crunching because it is cross platform capatable. The HCC GPU betas are a good example. It would make no sense to code for OpenCl on ATI and CUDA on Nvidia for the same project when OpenCL will work on both. JMHO

I think (without knowing for sure) that the project scientists are taking the lead here. My understanding is that the HCC scientists started with CUDA but switched to OpenCL for reasons of their own. I do not think that WCG is being proscriptive about this. Instead, we attempt to accommodate the project scientists within reason.

Obviously lots of problems. I wonder has anyone approached the University of Waterloo, Ontario or the Karlsruhe Institute of Technology?

OpenCl still has awhile to go til it catches up with CUDA though. Agree cross platform is nice, but IMO it is probably at least one reason (among many) for the issues we've been having. Currently CUDA is more "mature". Hopefully we get a full project eventually or at least an extended beta.
Here's to hoping. |

On the balance, OpenCL is the smarter choice to start things off. Later, I also would want an optimized-for-AMD/ATI GPU-apps, and for nVidia fans, a CUDA-based GPU-app.

About the only reason for OpenCL that I know of is to avoid separate AMD and Nvidia GPU apps. Or to put it another way, if you were going to develop separate optimized apps for each of them, you wouldn't need OpenCL to begin with.

Or to put it another way, if you were going to develop separate optimized apps for each of them, you wouldn't need OpenCL to begin with. To be more accurate, you would only need the one app for AMD, nVidia, AND CPU (x86/64 + ARM). So, if you have a wide variety of hardware at your disposal, it would be smarter to lose a little efficiency to gain the extra hardware potential. However, it has been a very long and bumpy road for many projects to get the single app to accept both AMD and nVidia. Most get AMD to work and then lack nVidia.     |

There is hope for unity in the sense that the next generation Nvidia card (after Kepler) is Maxwell, which runs only on OpenCL as I am told, since it includes an ARM processor (don't quote me on that though). So that will force some unification, though I am sure there will still be differences between the efficiency of AMD and Nvida, but at least it will be easier to develop.

I hope nVidia does not fork OpenCL.
