2) Message boards : News : OSX applications updated again to v0.31 (Message 40548) Posted 20 Jun 2010 by Alan Stafford Post: I have a 0.3 running. Sat 19 Jun 16:40:26 2010 Milkyway@home Resuming task de_11_3s_2_243371_1276861664_1 using milkyway version 30 Looks very strange Should I abort it or let it run? Using BOINC Manager 6.10.57, wxW. 2.8.10 Alan[/img] I had a system lockup not sure if it was related to a BOINK or MW. I had to do a hard reboot. After that was complete the task had been completed and was reported to MW. It showed in my tasks as waiting validation, but there are no tasks there now. Does not look as if MW is compatible with my system but I will try again. Alan

4) Message boards : Number crunching : Problems with GPU usage for a iMac11,1 with quad core Intel i7 processor and ATI 4850 GPU 512 MB.. (Message 40391) Posted 15 Jun 2010 by Alan Stafford Post: Developers target Windows first, Linux second and the Mac third ... DENETC at the moment is windows only (ATI, CUDA, and CPU) ... likely the next applications will be made available on Linux and only later can we expect to see a Mac version... Well, I'll unquestionably be making things work on Linux and OS X first where things actually work. I've been battling to get anything to even build on Windows for the past 3 days. It's quite painful. Yes I know and I have to work with the crap in my job. W7 not so bad though, only computer chess game I can beat at highest level. Found this paper at Aqua, OpenCL runs only slightly slower than Cuda. And support is available for all OSs; ATI, NVIDIA and other GPUs, though admittedly at an early stage. http://arxiv.org/abs/1005.2581

Soon you'll be racking up big credit numbers. Of course, you can attach to other projects too; BOINC will keep both your CPU and GPU busy. I have seen posts from people with macs running ATI cards as coprocessors. It is just not working with Snow Leopard as far as I can tell. I just double checked and none of the three projects listed in your message that has an ATI application has one for the Mac. These projects do have an ATI application for Windows, and in some cases also for Linux, but no one has an ATI application running on OS-X ... MW and Collatz can run on the Mac on the CPU side and there is the one CUDA application from Collatz that runs only on the GPU and the Einstein beta application that runs on the CPU and GPU ... AND THAT IS IT ... Developers target Windows first, Linux second and the Mac third ... DENETC at the moment is windows only (ATI, CUDA, and CPU) ... likely the next applications will be made available on Linux and only later can we expect to see a Mac version... The project with the widest applicability is Collatz... And I would look to them to be the first out with an application for the ATI cards on the Mac if anyone does it ... then likely MW ... but the limitation is that ATI has not released the right drivers yet for the Mac platform and until they do, nothing is going to happen ... It is not your fault. The BOINC download GPU projects listing is misleading, they should be more explicit about which operating systems and GPUs that are supported. Good luck with the Mac ATI GPU project etc as your post. Alan PS Hi Steven, Thanks for your reply. I will forward this on to the BOINC team. I suppose the kernel is strictly 10.3.0. They are using the wrong command. They and a few projects and some hardware monitoring software like atMonitor ( gpu% ) don't detect ATI GPUs at least on my iMac 11,1 .

Notes: Boinc uses this to resolve the operating system version but perhaps they should use another way? http://boinc.berkeley.edu/ Best way to identify GPU might be /usr/sbin/system_profiler but the output is long and will need to be awked or something.

(Message 40139) Posted 2 Jun 2010 by Alan Stafford Post: My RAC has plummeted from ~5000 to ~4000 since I have been trying to get ATI GPU going. I think I will upgrade Boinc and try once more. But if that does not work I will delete Aqua and Milkyway and return to just running Einstein. I will keep an eye on progress. I remember it took me a while to get Einstein making optimised apps for mac. Alan

(Message 40079) Posted 31 May 2010 by Alan Stafford Post: There is no brook drivers for OS X yet, the only way you would be able to use the GPU on Milkyway would be to boot into Windows and run it that way. I think we might even have to wait until OpenCL matures completely. Do Milkyway or Boinc use the BrookGPU? The only project I know that uses that is Folding@home and not for Apple Mac. I hate Windows, I did set-up a boot partition with the pre-release Windows 7 64 bit, and I retain a version of W7 under Vmware. But I only use it to unpack some content archives or installers that I can't do under MacOSX. Seems a bit extreme to have to change operating system to run your community projects. Thanks anyway for your reply. Alan

(Message 40078) Posted 31 May 2010 by Alan Stafford Post: Go to your preferences and select - use GPU while computer in use (in mgr) and on the web site - select Use ATI GPU if present. I had done that and there is no, "Use ATI graphics card option". Can't set it to zero as I get an out of range error. It is the, "Sun 30 May 22:48:02 2010 No usable GPUs found" that worries me. Thank-you Alan
