Congratulations to the AQUA@home project, which has deployed the first OpenCL application on BOINC. OpenCL is a new programming system for GPUs and multicore CPUs.

Please link to something on Aqua that talks about this new app. Thanks

We have an OpenCL version of the aqua app. I have to emphasize that this is a test version and we may never deploy it on AQUA. It seems to run on my NVIDIA GTX 260 with no problems, but it needs to be tested further. Specifically, I am wondering how it would work on:

1) an ATI GPU.
2) a system with two or more GPUs (doesn't matter whether NVIDIA or ATI) to see if it can be set to run on one or the other GPU.

Would anybody with a suitable hardware setup and with OpenCL installed be able to test the app?

The scientists of the WCG Nutritious Rice project are also developing on OpenCL, but it may never get deployed into public grid computing.

I have also run AQUA's test offline on a Fermi (GTX 470). In my particular case (possibly slightly atypical hardware), the OpenCL version was approximately 10% slower than the CUDA version, and in addition used much more CPU resources.

I think that we are still at the 'proof of concept' stage - we await more mature OpenCL programming and runtime support. But it's good to know that the possibility exists.
