I tested the execution of my code using the option -mca coll ^inter as you suggested and the program worked fine, even when I use 1 server instance.
What is the modification caused by this parameter? I did not find an explanation about the utilization of the module coll inter.
Thanks a lot for your attention and for the solution.
Thanks for the response. I just did not understand why the Barrier works before I remove one of the client processes.
I tryed it with 1 server and 3 clients and it worked properly. After I removed 1 of the clients, it stops working. So, the removal is affecting the functionality of Barrier, I guess.
Anyone has an idea?
