Hi everybody,

So, first of all: We will not use CUDA in our app. OpenCL can do everything CUDA can do and there's really no need to use it anymore (however that's my opinion). Apart from that we are working hard to get everything to work in Single Precision. So far our forcefields are exact in single precision with the exception of our Solvent Accessible Surface Area term, which will be deployed on the CPU for the moment. The new SASA forcefield is about 7 times faster than the old one on the CPU already though and during the next time somebody will be working to deploy it also on GPUs.

So the GPU part will be single precision and OpenCL; there's also no question whether we release first ATI or NVidia - these two releases won't be more than 1-2 days apart for sure, because the code is not different apart from optimization parameters. Personally I use the ATI Stream SDK on CPU for debugging bugs usually.

As to release dates: Well we were a bit off, when we estimated POEM++ to be done for the end of CASP, therefore at the moment we are hesitant to specify an immediate release date. The CPU part however is done and we are thinking to release it first, because it also gives already quite a speedup.

Best,
Timo
