And I attempt to install from source or binary, but no change. And the OS is CentOS Linux release 7.3.16.11

What’s your PyTorch version? Also, did you try running e.g. with 4 OMP threads? I think the problem appears because when you’re using all the cores, they’re competing over cache space and can’t proceed as effectively.

My pytorch version is 0.1.10. And as you say, set the OMP_NUM_THREADS=4 and it works well. Thanks for your reply.
