Hi Kosta,
I am not all that familiar with the udp conduit, and seeing as one of the
conduits (SMP) works, your installation is fine. I think the Berkeley team
can assist you further.

Hi Proshanta,
What I get from 'upcc -version' on both clusters has been attached
to the current e-mail.
So, the 'Working' file attached is what I get from the cluster where
I don't get any problems.
The 'NotWorking' file attached is what I get from the cluster where
I have the problem.
However, I have to mention here that I get this problem if I
compile my program with -network=udp. If I compile with -network=smp,
then upcrun works fine on both clusters. Just -network=udp gives me
problems on one of my clusters. Is there sth that needs to be enabled
that might not be enabled on one of my clusters?
