Prof. Pande has posted an update on the progress of the new ATi Folding core, it's just waiting on the new v7 client and older cards need not apply.

We have been working to improve our support for AMD/ATI GPUs. AMD/ATI originally supported the Brook language for GPU programming, but has since moved to OpenCL, dropping support for Brook. This means that in order for FAH to support ATI GPUs, we have had to rewrite our ATI GPU core in OpenCL. This has been a huge undertaking, but is coming to fruition (check out http://simtk.org/home/openmm for details and a change log with progress updates). Due to ATI's decision to drop Brook in lieu of OpenCL, new FAH ATI GPU core development can only be done in OpenCL and thus can only run on GPUs which ATI supports with OpenCL.

We want to give ATI donors a heads up that ATI does not support all of its GPUs with OpenCL (the series 3xxx are not supported and the series 4xxx does not have sufficient OpenCL support for efficient FAH calculations). For the short term, we will support both the older (Brook coded) ATI core 11, and the newer (OpenCL coded) ATI core 16, but we cannot support the Brook-based core for much longer. We plan to support ATI core 11 until September 1, 2011 (hopefully longer, but we want to get this on donors' radars). Closing support for a given platform is never a popular decision, but in this case, we have no choice due to the lack of vendor support of that platform.

The good news is that ATI's support for OpenCL is very strong and we're excited about our new ATI openCL core (core 16), which is undergoing testing right now. ATI core 16 will be publicly released after the v7 client is released, as the core needs the new client.

why thank you for the heads up....should one expect good numbers from his 5 and 6 series card? :)

And me, the ATI fan who has 11 nvidia cards in his house right now. All were puchased for folding. Maybe I can buy ATI cards again. But saddly me thinks the nvidia cuda thingy will prevail. Hope I am wrong...we need ATI/AMD around or we will pay through the nose for stuff, so I will support them as much as I can. Next build....Bulldozer and 6970s....?

If it works through OpenCL, why can't that same client support NVIDIA GPUs?? OpenCL is a completely supported extension through CUDA.

You'd know the ins/outs better than the majority of us SKY, so please correct me if I'm wrong, but isn't there a good chance that running OpenCL on an Nvidia card would add an extra layer of coding and thus not be as efficient as running native CUDA?
