11) Message boards : Sieving : ppsieve/tpsieve CUDA testing (Message 27622)
Posted 3540 days ago by Profile LookASProject donor
my processing speed below 43000G is around 14.4Mp/sec and above 43000G is around 18.5Mp/sec

Interesting. The absolute distance between the 460s and the 470s does not change significantly in the higher ranges.

it gets faster with higher Gs. when i start 74000G-75000G range im getting this:
p=74005793644545, 19.94M p/sec, 0.16 CPU cores, 0.6% done. ETA 05 Nov 06:47
edit: 20.28Mp/sec when i leave pc alone.

i dunno what that is, but your result is this high because of nstep=33. from 43000G+ nstep has risen to 33 (from 32) and processing speed has risen as well.

my processing speed below 43000G is around 14.4Mp/sec and above 43000G is around 18.5Mp/sec

edit: also i`m experiencing at 43000G-44000G gpu usage drop from constant 98% to ~86-90%, along with temperature drop. dunno why.

in short what you need:
this cudart.dll
this ppsieve-cuda application.
app_info.xml from this post.

then you should be able to do CUDA work, but no other else, unless you edit that .xml

true, at least in my case. i still have to use app_info.xml.

This would come in handy to me right now as well :)

You could allways put the other apps from a normal client_state.xml into your app_info.xml and go on crunching other things on primegrid.

I did not have time to finish it. thx for pointing me the right direction ;)

I am using app_info.xml from this post with 'last' 0.2.1a app from here and it works fine (except i cannot obviously compute any other things on PG )


anyway in ma case with OCed GTX470 (760MHz GPU), Windows 7 Ultimate 64b, driver 260.63 -> 01:46 min

Anyone having graphics slowdowns with GTX 460/470 and my app? If not, I could try doubling the work-per-kernel and see what happens.

I keep thinking it might have to do with 48 vs. 32 threads per multiprocessor; but the latest CUDA Occupancy Calculator doesn't show anything like that.


No. The only problem I have with the card that I can get no regular WUs but thats slightly Off-Topic here...

same here.. no graphics slowdowns (...and no regular wu :( )
