Hey again,
This is done :)
You can check on ./examples/autotuner/gemm_autotuning --help and tell me if
it is alright ! It is not heavily tested (I'm on my laptop) but he basic
tests suggest that it works.
I have added TCLAP , a MIT header-only cross-platform lightweight library
to parse command line arguments, this was in my opinion by far the cleanest
option, handling well optional/mandatory arguments, contraints etc...
Best regards,
Philippe
