Titan X Maxwell (old) issues

Hi All, I am having a strange problem on all our Titan X Maxwell (older one) with pytorch:

We are on: Ubuntu 14.04.5 LTS

I can confirm we can run Torch7 on those machines with no issues.

Also on the new Pascal Titan X, we do not have this problem. Maybe an issues with driver?

Anyone else has the same issue?

We don’t support Python 3.4 Do you still have this issue with Python 3.5?

After @smth recommendation I updated nccl and was able to make one workstation work that way.
