V10/11 of modified SETI MB CUDA + opt AP package for full multi-GPU+CPU use
elec999:
Just a Quick Question. In one of my system I have the GTX260 and 8800GT, boinc is seeing it as two 8800. Doest it matter.

OK. My file only has the character 1 in it. How do I identify a NX8500? And, just today I received a NX9800GTX for a new PC. How do I identify that?
In other words, what text does the GPU file expect to see other than the number of GPU's?
Or looking at it another way, where's a help page on how to identify a GPU?
BOINC knows about the GPU. I see it in Messages tab when BOINC starts up.
Thanks

My number of GPU file just says 2 for 2 GPUs.
Thank you

Did you forget question sign after end of sentence?
If yes - answer is no.
If it was your suggestion to other members - please, stop making incorrect assumptions about way pack is working. There should be NOTHING except single number.
It described in first post, plese, read already available info before start to invent something. This can lead only to more caches trashing...

Perhaps I just don't understand what is supposed to happen. I allowed AP and SETI WU in SETI preferences. I ask for 10 days of work in my cache.
Since then I have no SETI work at all, only AP. And I have only a maximum of 8 AP WU in cache, about one day of work (~12 hr/APWU). My GPU is continuously idle whereas before AP it was always at 100%.
What I expected to happen is some cores would do AP, some SETI, my GPU would be busy with SETI WU, and I'd maintain enough work for 10 days.
My operating conditions are as stated just 4 or 5 posts down:
Conditions:
XP SP3
Q6600 processor
<cc_config>
<options>
<save_stats_days>120</save_stats_days>
<ncpus>5</ncpus>
</options>
</cc_config>
number_of_gpu = 1
NX8500GT GPU
V10 installed.
From my perspective enabling AP is not a good thing. Not only have I taken a huge hit in RAC until if and when credit grants catch up but my GPU hasn't done a tick of work. It seems for many of my AP WU my wingman errors out, opts out before finishing, or is working with a P2-200 that can't possibly finish before the deadline. The RAC is nice at 1,250 per WU but not if its never credited.
I don't mind so much, waiting for credit grants to start flowing. But I do mind an idle GPU.
Is it accurate to say, if I want a hardworking GPU I need to disable AP?
Or, do I need an entry in app_info.xml or cc_config, that will permit CPU crunching of AP and SETI, and also SETI crunching on GPU - as the name of this discussion implies?
Thanks
