Oscar,
As I mentioned before, I've never used SGE. So please ask
for Reuti's advise. Only thing I can tell is that you have
to use the openmpi 1.8 series to use -map-by slot:pe=N option.

Reuti,
Sorry for confusing you. Under the managed condition, actually
-np option is not necessary. So, this cmd line also works for me
with Torque.
$ qsub -l nodes=10:ppn=N
$ mpirun -map-by slot:pe=N ./inverse.exe
At least, Ralph confirmed it worked with Slurm and I comfirmed
with Torque as show

Hi, Filippo
When launching with mpirun in a SLURM environment, srun is only being used
to launch the ORTE daemons (orteds.) Since the daemon will already exist
on the node from which you invoked mpirun, this node will not be included
in the list of nodes. SLURM's PMI library is not involved (that

I have a problem that is related to the integration of OpenMPI, slurm and PMI

out why we were not able to obtain all H5 profile files (generated by

Hi
Well, with qconf -sq one.q I got the following:

Rio is using the kernel.org drivers that are part of Ubuntu/3.13.x and
log_num_mtt is not a parameter

Hello!
As i can see, the bug is fixed, but in Open MPI v1.9a1r32516 i still have the
problem

Just to clarify: OMPI will bind the process to *all* N cores, not just to one.

Reuti,
If you want to allocate 10 procs with N threads, the Torque
script below should work for you:
qsub -l nodes=10:ppn=N
mpirun -map-by slot:pe=N -np 10 -x OMP_NUM_THREADS=N ./inverse.exe
Then, the openmpi automatically reduces the logical slot count to 10
by dividing real slot count 10N by b

I have a performance problem with receiving. In a single master thread, I made
several Irecv calls:
Irecv(buf1, ..., tag, ANY_SOURCE, COMM_WORLD)
Irecv(buf2, ..., tag, ANY_SOURCE, COMM_WORLD)
...
Irecv(bufn, ..., tag, ANY_SOURCE, COMM_WORLD)
all of which try to receive from any node for messages
Reuti and Oscar,
I'm a Torque user and I myself have never used SGE, so I hesitated to join
the discussion.
>From my experience with the Torque, the openmpi 1.8 series has already
resolved the issue you pointed out in combining MPI with OpenMP.
Please try to add --map-by slot:pe=8 option, if
23 matches
