Subject: [OMPI users] Strange Execution block each second
From: Mathieu westphal (mathieu.westphal_at_[hidden])

I've coded an mpi programm who run on 9 process. 7 process are in one
node, 2 other on another node.

It works really good, but sometimes it's kind like the 8th process block
for 10ms.

Here is the scheme of the error

Normal execution 1000 ms | 10ms BLOCK | 60 ms execution | 10 ms BLOCK |
1000 ms execution .... and so on.

It's always the 8th process who block the programm.

Do someone experience any similar behavior?
