Tiled Matrix Matrix Multiply

Hello,

I have been trying to find a parallel (GPU+CUDA) tiled SGEMM, to solve big matrices which otherwise would not fit in GPU memory.

A friend of mine said he once saw a Magma version of tiled SGEMM, but I can't find it.

Does such implementation exist?

Thanks for your time...

Yes, there were tiled algorithms in MAGMA. These have been split off into the MORSE project.

Note that the regular MAGMA gesv (getrf) and posv (potrf) will handle matrices larger than the GPU memory, as well as multiple GPUs.
