As for the --quiet flag, that's an option passed along to gretlmpi,

Ok,
I'm pretty sure that the problem is related with communication between
MPI nodes. In attachement there is an example, which:
1. On Linux with OpenMPI or MPICH works perfect.
2. On Windows 64 (I've tested 7 and 10) with current MS MPI (v10.1.1):
2.a. works perfect in case on 2 MPI nodes,
2.b. randomly works in case on 4 MPI nodes.
Switching off antivirus helped a little: processing time decreased.
Specyfying the port number (via "-p" flag) doesn't help.
Any ideas?
