Hi everyone,
may I have your help on a strange problem?
High performance computing is new to me and I have not much idea about OpenMPI
and OpenFoam (OF) which uses the "mpirun" command.
I have to support the OF application in my company and have been trying to find
the problem since about 1 week
Hello Andre,
It may be possible that your openmpi does not support threaded MPI-calls (if
these are happening). I had a similar problem, and it was traced to this cause.
If you installed your openmpi from available repositories, chances are that you
do not have thread-support.
Here's a small s
Hello,
It would be useful for the end user to use mpic++ to obtain the compile and
link flags for both release and debug builds.
There is a number of possible solutions:
1. add the showme flags of mpic++ and any other similar binary to
something like -showme:compile_debug -showme:compi
Hi,
I think I've found a bug in the hear revision of the OpenMPI 1.5
branch. If it is configured with --disable-debug it crashes in
finalize on the hello_c.c example. Did I miss something out?
Configure options:
./configure --with-pmi=/usr/ --with-slurm=/usr/ --without-psm
--disable-debug --enabl
Hprobably a bug. I haven't tested that branch yet. Will take a look.

hi,
when my wireless adapter is down on my laptop, only localhost is configured.
In this case, when I mpirun 2 binaries on my laptop, mpirun fails with this

Have you tried to specify the hosts with something like this?
mpirun -np 2 -host localhost ./my_program
See 'man mpirun' for more details.
I hope it helps,

The problem is that OMPI is looking for a tcp port for your computer. With no
network enabled, you don't have one, and so mpirun aborts. I don't know of any
way around this at the moment.

Well, I'm afraid I can't replicate your report. It runs fine for me.

After some searching, it turns out mpi4py tries to call MPI_Init_thread but
python in general has issues with threads apparently. I'm backing off from
threading at this point.

Hi, I'm having odd issues with my "cluster", I guess. This very simple example
works on one machine, but it gives a load of err
