BRP4cuda32 vs. BRP4cuda32nv301 performance
In the past weeks I have been using the 276.52 driver (released 2012.02.09) enabling me to run the BRP4cuda32 application. Using this driver/application it took my Nvidia Quadro FX1800 arround 6200 seconds to complete a WU and get the 500 credits.
After updating to the most recent 305.93 driver (released 2012.08.28) I am able to run the BRP4cuda32nv301 application. This seems to put more load on the GPU, since my system becomes less responsive. Therefore I would expect the runtimes to be shorter than when using the old driver. However, now a WU takes arround 19000 seconds to complete - and I still get 500 credits.
My questions are:
- Are my GPU performing better using the old driver and the BRP4cuda32 application?
- Or am I doing any better with the new driver (eg. crunching more numbers), and the credits are just not adjusted properly?
The "credit/time" might not be a very accurate measurement of performance.
