[OMPI users] checkpointing 2 or more processes running in parallel

2009-08-27 Thread Jean Potsam
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. On Aug 27, 2009, at 11:01 AM, Brock Palen wrote: We have a case where we need to spwan

[OMPI users] openmpiu 1.3.3. with OpenFOAM

2009-08-27 Thread bastil2...@yahoo.de
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

[OMPI users] Launch jobs with TM, but allocate with node files

2009-08-27 Thread Brock Palen
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. Lenny Verkhovsky wrote: Hi all, Does OpenMPI support VMware ? I am trying to run OpenMPI 1.3.3 on VMware

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 Lenny.
