I'm trying to have SETI or Folding utilize my GPU- An AMD Radeon HD 6750M 512 MB in this case. There is widespread support on Windoze, but the Mac seems to be left out of the GPU party. I don't understand it, especially with decent GPUs now shipping in iMacs and even MacBook Pros, not to mention Mac Pros.

Has anybody gotten GPU to work with either of these projects? If not, perhaps I can find another worthwhile project that will indeed take advantage of my otherwise idle GPU.

The BOINC projects Collatz Conjecture, Einstein, and PrimeGrid all have GPU support in OS X, but only with Nvidia GPUs (and Apple currently does not sell any Macs with Nvidia GPUs right now). I am upset about this to because my Hackintosh has an AMD gpu and hope to do some distributed computing when the weather gets cooler.:p
Maybe because only Macs with AMD GPUs are for sale right now, AMD compatible projects will be developed.

As for folding, that may be part of the plan for a later v7 client.

Wherever my feet take me…
Awful how all the focus is on Windows, although I do understand it considering Windows has ~90% marketshare.

OT, sorry: Distributed computing is pretty cool IMO, but some reason for some projects go over my head. I'll admit, I'm no math whiz or anything. So what's the point of the Collatz Conjecture? I've also heard that stuff like SETI doesn't matter too much because any radio transmissions from other planets would have dissipated by the the time they got to Earth. I'm sure many of the projects have good reasons, but hell if I can understand.

Check out Einstein@Home, it uses BIONIC Manager and computes for NASA and University of Wisconsin

It's actually a lot to do with how difficult it can be to write and use decent OpenCL compilers for Mac for the purpose of creating dynamic and memory-effective GPU applications.

NViDIA is pretty good about saying "oh cool, you wanna write something in CUDA? for science? Absolutely, we'll help!!" while ATi kind of does their own thing.

In a way it's great that the newer Macs have the 67xxM series of Cayman cards, since it represents a huge increase in the raw DP-capabilities of GPU-accelerated Mac computing. It's sad that only the Mac Pro currently has the largest capability for actual GPU installation and use. NViDIA makes CUDA drivers for all sorts of Mac platforms and GPU installations, while ATi seems to hide their advanced OpenCL drivers.

Bear in mind that (I think) the APP and OpenCL drivers one would need for BOINC are already installed with your OS.

That said...at the moment only PrimeGrid has a functioning ATi (ati13ati) app for their PPS sieve, and I have not tested it myself yet.

Collatz's admin has long told me and others that if he ever gets a Mac he'll write a better CUDA app, but that nowadays seems moot since if he gets a Mac now it'll have ATi in. That's great, actually, since many projects like that are better suited to ATi cards and the types of math they do better.

You're welcome to try running a few of the BOINC projects (like PG) with ATi apps for Mac...or try your hand at getting Parallels to recognize your GPU, which I've never had success in doing.
