Hi again,
after testing as suggested, it is indeed a massive slowdown rather than
a full-blown machine hang.
Would the next test be to run with debug flags for openmpi ?

Olivier Marsden

Hi Jeff, thanks for the response.
As soon as I can afford to reboot my workstation,
like tomorrow, I will test as you suggest whether the computer
actually hangs or just slows down. For exhaustive kernel logging,
I replaced the following line
kern.* -/var/log/kern.log
with
kern.* /var/log/kern.log
in my /etc/rsyslog.d/50-default.conf file, does that look about right?
I'd add another:
*.* -/var/log/everything.log
...because who knows what the actual problem is?
And/or, if you have another machine that can listen for syslog, remote syslog
to that machine so that you might be able to see the results more or less
immediately.
