Title: laptop with quadro nvs 140m
Post by: chronek on 08 Apr 2009, 08:03:32 am

Hello
I have problem with gpu crunching on nvidia quadro nvs 140m - setiathome_6.08_windows_intelx86__cuda.exe use 100% of one cpu - i using 181.22 beta notebook cuda driver with inf update from laptopvideo2go site , boinc 6.6.20 , marks app_info.xml ... the same settings with laptop with gf 8600m gt working like a charm ... but here - cuda crunching use 100% of one cpu core...
Have someone the same problem?>

hmm i found , seti-cuda going to fallback because of not enough video card memory , but it is strange that cuda needs at least 256MB , when cpu crunching only 64Mb with system
Can someone tweak seti-cuda to run on video card who have only 128Mb ?

I was Beta Testing MB 6.07/6.08 with the CPU fallback mode on my 128Mb 8400M GS, very very slow, took up to 6 hours a WU, when AK_V8 takes a hour and a half or so,
Then there was the problem of Boinc 6.4.5 running 3 apps on the CPU (on a dual core), haven't tried running the Cuda app on Boinc 6.6.21 to see what happens, Yet.
I suppose the optimisers could try lowering the memory requirement, or finding ways to use less memory, But i don't think it would be very high on their Priorities.
