There's huge differences between Open MPI v2.1.1 and v4.0.3 (i.e., years of
development effort); it would be very hard to categorize them all; sorry!
What happens if you
mpirun -np 1 touch /tmp/foo
(Yes, you can run non-MPI apps through mpirun)
Is /tmp/foo created? (i.e., did the job

The program is not executed, seems waits for something to connect with

To Whom It May Concern:
I have a program that I am running that has the MPI call fork() and when I run

run something in one computer. I just installed the new OS an openmpi in
two different computers, in the standard way, with the same result.
Hi Jorge
You may have an active firewall protecting either computer or both,
and preventing mpirun to start the connection.
Your /etc/hosts file may also not have the computer IP addresses.
You may also want to try the --hostfile option.

Hi Alan,
I do not have any experience building Open MPI with the new “flang” compiler
