    Jocl OpenCL speed difference between processor and graphics card not what expected

    mordock2012

      Hello,

       

      I am using JOCL to run some kernel against both the CPU and the graphics card. The processing works fairly quickly for the processor but takes forever for the graphics card(Actually I have never waited for it to finish..and I've ran the code all night).

       

      Would anyone happen to know what could be causing a the speed difference between the graphics card and the CPU. I was expecting the graphics card to run things faster. As it stands, the processor finishes the task and the graphics card takes forever and has not finished yet.
