I have been testing the same code, on the same computer, for some reason when i measure times on both, the times have a very big difference.
Using the same configuration (CUDA 7.5) and exactly the same code on both SO. For example this it’s quite the results i have been getting during the testing :
Ubuntu : 38. 99 Seconds
Windows : 118.72 Seconds
Both SO have CUDA 7.5.
Ubuntu : 15.04
Windows : 10
Maybe the only difference it’s that Windows has the latest driver version and Ubuntu has the same version that came with the Nvidia 7.5 Driver.
Anyone can give a hint , why this is happening?..
Both programs have been compiled and run as release version.
