Are you sure that all processes reach the allreduce statement?
If something like this happens to me, i insert print statements just

I have 3 computers with the same Linux system. I have setup the mpi cluster
based on ssh connection.
I have tested a very simple mpi program, it works on the cluster.
To make my story clear, I name the three computer as A, B and C.
