1) Message boards : Number crunching : Running on ATI & Nvidia in the same rig? (Message 56476) Posted 12 Dec 2012 by DeathCom Post: LOL, I know, I just can't do this the easy way. I added app_info for both cards and its now running 4 WUs at once! Yay! PC is laggy as hell, both gpus at 100%, but thats what I wanted when Im not using it. :) After letting it run with this new setup a while, I have noticed that indeed my other observation is also a problem. Most often, MilkyWay is overloading the 5870 with WUs and the GTX260 doesn't get any because of that. Manually disabling future WUs for ATI allows nvidia units to download for a time, then I have to re-enable nvidia. So, I imagine there is some app_info code to set a max WU per GPU type?
2) Message boards : Number crunching : Running on ATI & Nvidia in the same rig? (Message 56470) Posted 12 Dec 2012 by DeathCom Post: Ok, I finally got WUs for both the 5870 and GTX260. It turns out the problem was actually SETI, they sent in enough WUs I guess to make BOINC think the 260 was too busy to get any more WUs. It's only getting about 5 Milkyway WUs at a time, but it's getting them. The usage of the 260 also seems to bounce between 40% and 80% constantly which is quite odd. It might also have been a shortage of nvidia WUs in general. Anyway, I can't seem to find a way to keep both cards working Milkyway and run a custom app_info to crunch two WUs at the same time per card (so 4 WUs total). If I put the app_info I used for my 5870 the 260 no longer gets WUs again. Now I was considering another option, I have a 3870 in another rig, I could swap the 260 for the 3870 and have both ATI cards in the same machine. But since the 3870 seems to need an app_info of its own to get WUs for the 32bit version of the app, I figure I'd have similar issues. (I sorta want to put the 260 in the other PC simply because it beats out the 3870 for everything outside of Milkyway.)

(Message 56218) Posted 17 Nov 2012 by DeathCom Post: Double checked all the settings, Milkyway is set to use both ATI and Nvidia, but not CPU (which it is adhering to). In fact, it used this same GTX260 fine when it was the only card in another PC. I tried adding the cc_config.xml suggestion, still no dice. It still just does not collect work for both cards, and favors the 5870 exclusively. As stated SETI@home will request work for both ATI and Nvidia, I stopped it from requesting ATI so Milkyway could have full use. I think it seems to relate to how Milkyway severely limits the total number of WUs you can get at a time. It gives you so many depending on how many (logical) cores your PC has. It's simply full when it tries to bother with getting work for the Nvidia card? Thanks for the suggestions so far though.

(Message 56167) Posted 12 Nov 2012 by DeathCom Post: While I know my Radeon 5870 destroys my GTX260 in terms of performance, I figure, why not get that extra 10K RAC or so from the 260? The problem is, I can't seem to get WUs for it. BOINC clearly has no issue with it for SETI@home gets units for both. Is there some magic I can work on the app_info to request units for both? While I'm at it, run two WUs on each card?
5) Message boards : Number crunching : Radeon 3870 no longer supported? (also a 7970M question) (Message 55093) Posted 12 Jul 2012 by DeathCom Post: Thanks guys, I think I got my old 3870 cruching again! The only issue is it seems to be running 2 WU's at a time... and I only have one card. So far so good though, will see if any of these get credited/complete...
6) Message boards : Number crunching : Radeon 3870 no longer supported? (also a 7970M question) (Message 55039) Posted 7 Jul 2012 by DeathCom Post: I noticed on my alternate PC I have setup that the 3870 in it no longer gets WUs for MilkyWay. It tells me in the event log Catalyst driver version is not OK for CAL application with this GPU / R600 does not support OpenCL. I know the 3870 supports double precision operations and worked with MilkyWay for years. Was it dropped due to MilkyWay or due to new drivers from AMD? Is there any way I can get this card working for the project, or is it time to retire it? Also, I hear the 7970M sucks for this but will it ever be supported? I notice it seems to think it is, but it continually gets computation errors.
