Hi,

I have been using the Intel Python Dist. for a couple of months. The first tests I ran with Python3 were impressive. Just by swapping Python distro I was getting 4x plus speedups using Theano/TensorFlow.

Today I installed the distro on a Xeon  virtual machine with 32 cores, and got the reverse surprise. So my IPD is 2x slower than cPython using Theano/TensorFlow. If I use explicitly TBB then it comes closer to cPython, but still a bit slower. Given this, I went back to test in my laptop (a core-i7, where I did not change the IPD, but have in the meanwhile updated the system cPython) and again IPD is slower than cPython.

I can only try to guess what happened, and I cannot reproduce exactly the environment I had before on my laptop. Maybe some bad update? How can I verify what may be going wrong?


Thank You!!!


I didn't find the right solution from the Internet.
