V10/11 of modified SETI MB CUDA + opt AP package for full multi-GPU+CPU use
elec999:
Is it worth running my AMD 3400+ and Intel P4 HT. Or are they just slowing down my other systems. Right now those two got work, and my other systems get no work.
Thank you
Marius:
A strange problem which occurs here from time to time is that sometimes when boinc 6.4.7 want to do some high priority tasks it starts a few new tasks but it seems to ignore the max amount of cpu's mentioned in the cc_config.xml (or is counting them wrongly). At such moments my q6600 and nvidia 9800gt are then running 5 cpu tasks + a gpu task (so 6 tasks in total).
Is this problem a boinc related problem or has it todo with a changed cc_config.xml or optimized client?
Any ideas?
Greetings,

Another problem i noticed; Sometimes the MB_6.08_mod_CUDA_V10.exe stops while its at 1 second of cpu (MB shows no activity in task manager and its using only 32.412kb of memory). It stays this way until i restart boinc. Is this a known problem/bug or can i solve/finetune boinc or nvidia software to avoid this?
It could be related to high priority boinc units which seem to overrule running threads (but i just as well be plain wrong)

Look this thread about CUDA app freezings: http://lunatics.kwsn.net/12-gpu-crunching/vbscript-fights-cuda.0.html
RottenMutt:
I'm running "stock" Boinc 6.6.17-64bit on my lappy, no optimized application installed yet. I immediately noticed that it will keep the GPU fed with work units, it also labels the Enhanced 6.08 work units as "(cuda)". It appears to me the latest Boinc runs cuda applications and fetches cuda applications as you would expect, woot!
I noticed in the c:/program data/.../setiathome.berkeley.edu folder there is not an app_info.xml file. If a install Raistmer's Opt V10a Pack along with a appropriate cc_config.xml file (or none) I end up running one more AP work unit then the number logical CPU's, rather then placing a 6.08 cuda work unit on the GPU.
So how can one use Raistmer's Opt V10a Pack and get it to behave the same as stock??? I think what is in the app_info file needs to be updated for the latest boinc.
what would keep me from renaming Raistmer's executables the same a the stock executable and copy the dll files? i really don't want to do that, they could easily be over written by Bionc.
