Latest drivers (NVidia and ATI)
Sutaru Tsureku:
Hmm.. O.K., I saw nVIDIA released the new 195.62 driver.
For CUDA_V3.0 .
Where I could get CUDA_V3.0 , and I could update my current opt._CUDA_6.08_V12_app with CUDA_V3.0 ?
Maybe one of the opt. crew is again kind and take the two .dll's out of the 'DL pack' and publish it also in the DL area here? :)
Or this CUDA_V3.0 must/should be 'modded' for SETI@home?
Jason G:
Hi sutaru. No significant speed advantage has been detected with 3.0. The improvements are primarily directed at unreleased hardware. We'll keep an eye on if the situation changes, but won't be rushing to build/release stuff for no advantage, or release SDK components under NDA (risking our nVidia licences. )
Sutaru Tsureku:
Thanks for reply! :)
Normally I don't like to use BETA software.
But.. if I know (and I know ;)), from where I could get the CUDA_V3.0_BETA - it would run well with the current opt._CUDA_V6.08_V12_app?
Or you would say.. no, better not to use CUDA_V3.0_BETA?
If CUDA_V3.0_final will be released in future, this two .dll's will be published in the DL area here?
It need to be modded, or just 'out of the box'?
I'm current with nVIDIA_driver_190.38. CUDA_V2.3 .
WinXP 32bit, 5x OCed GTX260-216. ;)
I would see a performance difference only with the new nVIDIA_driver_195.62 ?
AFAIK, new nVIDIA_driver are well for gaming people.
But, how it's with the only CUDA people? They profit from it also?
Sorry for my questions.. :)
Jason G:
Quite OK Sutaru. I would say no point risking task cache (especially with current project difficulty) until there is GT300 based card in your machine ;). 2.3 addressed a known cuda speed problem and helped us directly through the functions we use so made a big speed improvement. 3.0 doesn't, it adds more stuff we don't use (Yet, LoL ;) ).
Q: Do you currently run the GPUs flat out, and reschedule/kill VLARs? and leave CPU just mainly for feeding? If so I may have something worth for you to test soon, that may be a more important thing to study how it works. (after some school work is finished).
Sutaru Tsureku:
You didn't answered all my questions. ;)
My GPU cruncher:
http://setiathome.berkeley.edu/show_host_detail.php?hostid=4789793
4x EVGA GTX260-216 SSC supported by AMD Phenom II X4 940 BE @ 3.0 GHz.
(nothing on CPU, 4x CUDA)
My QX6700:
http://setiathome.berkeley.edu/show_host_detail.php?hostid=5069275
1x GIGABYTE GTX260(-216) SOC supported by Intel Core2 Extreme QX6700 @ 3.14 GHz.
(4x MB, 1x CUDA)
Here I use Fred's nice prog TThrottle, which increase the CUDA priority to 'normal'.
For max. GPU performance. :D
TThrottle? Small look in my profile: ;)

How would be the test?
It's 'safe' for the hardware/software? ;)
If PM, then please over the SETI@home site. There I'm every day.. ;)
