I am new in the cuda programming world. I am running a project that does some expensive computation on gpu cores or on cpu according to user input. The creators of the project claim it is faster on gpu ofcourse but they ran it on NVIDIA Fermi C2050 GPU while I am running on geforce 820 only 96 cores intel i5.
In my test the computation is faster running on cpu cores , is this possible or did I install the cuda and nvidia drivers wrong.
I am running on ubuntu 14.04 , cuda 7.0 , nvidia driver 346 . Also the screen was flickering so I installed a compiz refreshing package to fix flickering. Is this compiz package the reason of the slow performance or is it that my gpu card is so bad that cpu cores are better.
In the cuda samples folder I couldn’t find any project that compare speed of gpu with cpu , can you point me to a project that does this so I can be sure if it’s my hardware problem or their project’s problem.
