KeplerAs is opensource now.

Hello, guys,

I am releasing my assembler for Kepler GPU now.

My assembler uses frontend of Maxas to parse assembly, I modify the code in order to compile assembly on Kepler.

Any one want to optimize application on Kepler for extreme performance can try my assembler.

I also give an example of how to optimize SGEMM on Kepler:

I optimized the SGMM performance at 3104Gflop/s(88%), which is 15% higher than cuBLAS.

I also provide an automatic method to crack several generations of GPUs(I’ve tested it on fermi, Maxwell GPU).

More documents will coming soon after my thesis defense.
