1) Message boards : Questions and problems : run boinc and folding@home on same computer? (Message 30493)

BOINC and F@H usually play nice with each other on Windows. I set the CPU version of Folding at 50% cpu usage and it affects BOINC the least amount, yet manages to get its work done, too.

It will affect the output of both platforms a bit, but not it's tolerable with F@H backed off to 50% like that. I've never had either program crash or anything on WinXP Pro.

You can also run BOINC on the CPU and run F@H on an ATI card, as well. When I've done that, I could not detect any change in output from BOINC, as the GPU app didn't seem to use the CPU enough for me to register any change in output on BOINC. The ATI card will provide monster performance on the F@H GPU client.

Right now, my focus is BOINC and nearly all of my machines are running Linux, but in the near future I hope to set a machine back up with the above arrangement. It seems to be the best configuration if you want good F@H output without choking back BOINC output. I was using a Radeon HD3870 card when I had my WinXP machine set up this way.

Collatz is the only project currently with a 64-bit Linux GPU app for ATI cards, and I have been posting there, unsuccessfully, in my attempts to get BOINC to recognize the card.

I'm specifically looking for help from someone who has actually got an ATI card up and crunching on 64-bit Linux, hopefully Ubuntu.

I'm interested, too, in getting the boinc user added to the video group. The GUI tool lacks the necessary functionality, and the command:

sudo usermod -a -G video boinc

...also fails to do anything. This works in all versions of Linux I've ever used, but for reasons I can't fathom, fails to do anything in Ubuntu. I'm not optimistic about it making any difference, anyway. In spite of people's insistance on it working, for both Nvidia and ATI cards, I've never had to do it on the machines running Nvidia cards on 64-bit Ubuntu. But, worth a try if I can actually get it accomplished.

I put an ATI HD 3870 video card in an AMD Athlon 64 X2 5200+ machine running Ubuntu 9.10 64-bit and BOINC 6.10.17 and added the appropriate brooks libraries. I installed the latest 9.12 Catalyst drivers successfully and the card is working fine. I have reinstalled both the ATI drivers and BOINC to no avail. I'm getting the "no usable GPUs found" message in BOINC in spite of numerous efforts and much web research.

Has ANYONE gotten an ATI card crunching on 64-bit Ubuntu successfully?

I'd really like to get this up and crunching. I have applied every trick I could find, and have got Nvidia cards up and crunching GPU work on this OS, but I've reached a deadend here with the ATI card.
