So I just had the driver on the machine update to 370. I think this may have fixed the issue. I'll keep you posted.
A related question is do you know if anyone is working on nccl/tensorflow integration?
from nccl.
It appears the issue is completely resolved in the 370 driver. I'd close the issue but I'm curious on the answer to my tensorflow question.
from nccl.
@scott-gray adding NCCL to an existing computation-graph framework is pretty clean, e.g. https://github.com/caffe2/caffe2/tree/master/caffe2/contrib/nccl
from nccl.
