   > 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
dcslin@06ec6ce), 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.
   
   maybe can try adding s.wait() after each reorder, the stream process them one by one
