I did tests with Torch7 few days ago to compare it with OpenBLAS library on multiple cores against CUDNN. Single core difference was around 100x. Using multiple cores improved the situation but there still was about 15x difference that did not improve by adding more cores (I tested with up to Xeon 64 cores on a single machine). I did not test with Intel MKL library as I did not have time for this. I wonder how much these instructions would improve the situation and does anybody here have experience with Intel MKL library.
