Dear all,
I am trying to checkpoint an mpi application at specific points
in my program. So, i created a small function as follows:
void mychkpt()
{
system ("ompi-checkpoint -v `pidof mpirun`");
}
and I am calling it in my MPI application at specific points. e.g

Brock and I talked about this on IM -- the preferred solution would be
to set the cluster nodes limits.conf to allow interactive logins to
have unlimited locked memory. That would fix the OFED issue.

Dear openmpi-ers,
I lately installed openmpi to run OpenFOAM 1.5 on our myrinet cluster. I
saw great performence improvements compared to openmpi 1.2.6, however it
is still little behind the commerical HPMPI.
Are there further tipps for fine-tuning the parameters to run mpirun
with for this specia
I've never tried it. You might want to attach and see where it's stuck.

Yes, this could cause blocking. Specifically, the receiver may not
advance any other senders until the matching Irecv is posted and is
able to make progress.
I should clarify something else here -- for long mess
We have a case where we need to spwan many (random) allocated MPI jobs
within the same PBS job. (I have talked to the user about changing
this behavior).
The code will work If I do:
pbsdsh -n $(($GROUP*$JOBSIZE-$JOBSIZE)) \
mpirun \
-wdir $PWD/$GROUP \
This e-mail probably will not help you too much, but I'm pretty sure
1.2.6 worked just fine as I ran a simple MPI program with OpenMPI 1.2.6
and Debian Etch on top of ESX 4 without issue.

thanks,
Lenny.
mostlike that you compiled MPI with --with-openib flag, but since there are
no openib devices avaliable on
n06 machine, you got an error.
you can "disable" this message by either recompilnig Open MPI without openib
flag, or by disabling openib btl
-mca btl ^openib
or
-mca btl sm,self,tcp
