Topic 194007

The guys over at Orbit were having a fair bit of a discussion on GPU computing and BOINC. I was wondering if there was a GPU version of the science app in the works?

I vaguely remember some comments from the recent BOINC conference that (E@H) might be looking at one.

Hi!

The video of Bruce Allen's talk and now also the slides (which were kind of difficult to read in the video) are available for download: Boinc 2008 workshop proceedings.

The slides contain a hint on GPU app plans.

We have some code that doesn't compile with NVidias current SDK and last time it did it didn't give correct results. Might take a week of work to get this going at all, though the speedup is not that impressive. With some help from NVidia we also developed a new more promising approach optimizing memory access, but that's not gone into actual code yet. At the very moment nobody finds the time to drive this a bit further, due to a lot of other things with higher priority. It's definitely a pending item on Oliver's and my todo-list, but I don't know when we'll find the time to get back to that. Hopefully later this year.

I reckon it's just bonza that we're getting some input from NVidia on this. :-)

And I like the : "We will provide all the screensaver code nicely packaged so that
users can modify it or write their own. Based on new SDL graphics library (no more GLUT)."

Cheers, Mike.

Thanks a lot :-) looks like my card is on there... is this Windows only, or will there be a Linux version?

Looks like the CUDA SDK supports Windows, Mac, and Linux, so there's no reason a Linux app couldn't be made. Provided you're running the Nvidia drivers.

Actually the first version to come out will probably be for Linux. That's the platform the code is been developed on, both on our and on NVidias side. The Mac version should also be rather easy to derive from this; how to build an App for Windows out of that code is still a mystery to me, so that will probably come out last.
