In trying to debug an MPI_Waitall hang on a remote
node, I created a simple code to test.
If we run the simple code below on 2 nodes on a local
machine, we send the number 1 and receive number 1 back.
If we run the same code on a local node and a remote node,
we send number 1 but get 32767 back.
Your code works fine for me.
Have you disabled iptables / any other firewalling?
