Dear all,
The mpi_abort_delay parameters does deadlock the aborting process, as to ease
the manual attachment of gdb, only if the code does indeed call MPI_Abort.
Is there any similar command line trick to keep alive a process that is exiting
with assert() (or better with segfault etc) ?

A more detailed answer later, as it's late here. But one short note:

-pe orte 5-5 => the same

OK. Sorry for the delay. I needed to read through this thread a few times
and try some experiments. Let me reply to a few of these pieces, and then
I'll talk about those experiments.

Hello,
I have a process that creates other processes at different times (using
MPI_Comm_spawn). After, the initial process (creator of other processes) must
receive mesagens of created processes. However, there are one intercommunicator
for each created process.
The question is: how to unite
Recently the organization I work for bought a modest sized Linux cluster
for running large atmospheric data assimilation systems. In my
experience a glaring problem with systems of this kind is poor IO
performance. Typically they have 2 types of network: 1) A high speed,
low latency, e.g. Infinib
Hi all,
I noticed about 18 months ago in the user archives that the question of
heterogeneous support for clusters of Windows / Linux machines was raised,
and at that time this functionality was not supported.
Is this still the case? Are there any near term plans in this direction?

You were right about iptables being very complex. It seems that uninstalling it
completly did the trick. All my Send / Receive operations now complete as they
should. Just one more question. Will uninstalling iptables have any undesired
effects on my Linux cluster?
Thaks!

There is no iptables in my /etc/init.d.
It's most probably a communication issue between the nodes. However, I have no
ideea what it might be. It's weird though that the first Send / Receive pair
works and only subsequent pairs fail. Anyway, thankyou for taking the time to
help me out. I am gra
