Subject: [OMPI users] simplest way to check message queues
From: Brock Palen (brockp_at_[hidden])

I have a code for a user (namd if anyone cares) that on a specific case will lock up, a quick ltrace shows the processes doing Iprobes over and over, so this makes me think that a process someplace is blocking on communication.

What is the best way to look at message queues? To see what process is stuck and to drill into.

Thanks
