The difference is you are using an optimized AP application on your Mac but the standard (slow) version of the application on your server. If you want to the work units to run faster on your server install the optimized applications for Windows.

Just to be clear, your CUDA drivers are not in anyway interacting with the AP wu... There still aren't any (standard or optimized) CUDA seti apps available. Though we wait ever so patiently for them to appear one day...=) Chris ID: 1142692 ·

Last modified: 17 Aug 2011, 12:36:33 UTC Thanks for the heads up Richard! I will check it out. I do see that since enabling the CUDA drivers on my MacBook (4x CPU, 8GB Ram, CUDA GPU) I have now started getting AstroPulse workunits and they are completing in an average of 15 hours, where the server that I crunch on is taking ~72 hours for the same size WU... *"People sleep peaceably in their beds at night only because rough men stand ready to do violence on their behalf." - Orwell* ID: 1141577 ·

Does the 330M support double precision floating point math? Lion is supposed to have fixed a bug holding up some Open CL science apps for some projects using GPUs. Darwin Version 11.0.0 is I am sure OSX 10.7.0. Darwin is the name of the kernel for OSX. Version 10.x.x was OSX 10.6.x. I have not upgraded from Snow Leopard so mine is shown as Darwin 10.8.0 which corresponds to OSX 10.6.8 Darwin kernel version-----> OSX Version 11.x.x ----> 10.7.x 10.x.x ----> 10.6.x 9.x.x ----> 10.5.x 8.x.x ----> 10.4.x version before 10.4 not seen much in the wild any more. They had a change in version numbers for Darwin around the start of OSX around the 10.0 public beta and 10.0 final. I was not paying much attention at the time. ID: 1138867 ·

Einstien@home also can when they have work units. Good to know, maybe I can split and run that on the CUDAs while S@H crunches on the I7... *"People sleep peaceably in their beds at night only because rough men stand ready to do violence on their behalf." - Orwell* ID: 1138650 ·

Right now the only project that I know of with a Mac OS X CUDA application is Collatz. Thanks for the confirmation all... Hopefully that will come for SETI sometime in the near future... *"People sleep peaceably in their beds at night only because rough men stand ready to do violence on their behalf." - Orwell* ID: 1136217 ·

That answers my question, I read something about CUDA apps for Windows versions only, but there is an option in the Mac client to use the GPU for processing, so I wasn't sure if that was outdated info... I imagine it is present for the projects that do have MAC applications. I am not sure of which projects do at present.

I don't recognise 'Darwin 11.0.0' - I know that Charlie has been having difficulty tweaking BOINC for OS X Lion, but I don't know how the code names and numbers line up. And even if BOINC is working, that doesn't solve your problem finding a SETI CUDA application for OS X. Arkayn might know. ID: 1135999 ·

Assuming that you are talking about host ID 5953996, you can step through the pages of tasks sent to it here: http://setiathome.berkeley.edu/results.php?hostid=5953996 These pages show that you only have CPU tasks ATM (6.03). Not sure how that GPU stacks up against the minimum required, perhaps someone else would like to comment.... ID: 1135985 ·
