   Hi @chrishkchris , I am still working on this issue, but I am encountering something very
weird.
   
   I borrow the code from dnnl example and testing result shows similar performance compared
to mkldnn(conv forward in 5000~microsec).
   
   However, after some modification to the example code(just introducing Singa Tensor https://github.com/dcslin/singa/commit/06ec6ce8453f524640c704695d30d3f39fca0469),
I still can get reasonable performance(conv forward in 5000~ microsec). But the weird part
is, the result is not stable, out of 10 times testing, `segmentation fault` appear ~6 times.
