  BLISlab: A Sandbox for Optimizing GEMM

  

Efficient matrix multiplications or convolutions on CPU will use layered tiling to optimize registers, L1, L2 and TLB, L3 cache (if it exist). This improve speed by over 150x vs naive triple for-loop matrix multiplication and the same thing applies to convolution. See overview https://www.cs.utexas.edu/users/flame/laff/pfhp/week3-goto.html and actual exercises https://github.com/flame/blislab

As explained in https://github.com/NervanaSystems/maxas/wiki/SGEMM you need to do the same on GPUs.

Thanks, here is the code : https://github.com/Omeganx/Image-Convolutaion-OpenCL (I removed the other code I was using to make it focused around the convolution code)
