I think IMPI sounds pretty worthwhile, although I don't have any first
hand experience with it yet. The abilities to reboot a hung system or
get decent statistics about this, that and the other thing, seems worth
the cost in many cases, and my management has decided to require it on
all of our ne

Vincent,
So, I just get back from vacation today and I find this post in my huge
mailbox. Reason would tell me to not waste time and ignore it, but I
can't resist such a treat.

IPMI nowadays comes for free on the mainboard, and if you don't want to
run a separate
infrastructure for the light weight control traffic, then you don't even
need to add
ports/cables/switches. In case of a scyld beowulf cluster the compute
nodes are on their
own private network switch anyways so

I don't have a solution for your case, but here's an idea: MPICH-GM (MPICH
for the Myrinet GM protocol) has an option to mpirun.ch_gm that would do
what you want, if you were running Myrinet/GM:
--gm-killKill all processes seconds after the first exits.
Other than that, a resource man

In which case, one might use a small platform to elevate oneself and
one's shoulders.

Hi all,
I use MPICH-1.2.5.2 to generate and run an FEM parallel application.
During a parallel run, one process can crash, leaving the other
processes run and OS commands have to be used for kill these zombies.
So, does someone have a solution to avoid zombies after a failed
parallel run: can
