    floatn slow on gpu

    Sheeep

      Hi all,

      I try to speed up an opencl kernel, using vector data types.

      If I run the kernel on cpu, I get a speed up.

      but on gpu, the kernel is slower than with scalar data types.

       

      Is the use of vector data types on gpu unusefull?
