I built the current 1.6 branch (which hasn't seen any changes that would impact
this function) and was able to execute it just fine on a single socket machine.
I then gave it your slot-list, which of course failed as I don't have two
active sockets (one is empty), but it appeared to parse the li
How was OMPI configured? What type of system are you running on (i.e., what is
the launcher - ssh, lsf, slurm, ...)?

Dear users,
Maybe something went wrong as I was compiling OpenMPI, I am very new to linux.
When I try to run LAMMPS using the following command:
/usr/lib64/openmpi/bin/mpirun -n 16 /opt/lammps-21Jan13/lmp_linux < zigzag.in
I get the following errors:

Sure - just add --with-openib=no --with-psm=no to your config line and we'll
ignore it

I've looked in more detail at the current two MPI_Alltoallv algorithms
and wanted to raise a couple of ideas.
Firstly, the new default "pairwise" algorithm.
* There is no optimisation for sparse/empty messages, compare to the old
basic "linear" algorithm.
* The attached "pairwise-nop" patch add

You should not need to, we have OMPI compiled for openib/psm and run that same
install on psm/tcp and verbs(openib) based gear.
All the nodes assigned to your job have
or do i just need to compile two versions, one with IB and one without?

ahha, with --display-allocation I'm getting :

I think the system I compiled it on has different ib libs than
How did you configure OMPI? If you add --display-allocation to your cmd line,
does it show all the nodes?

Hi,
I'm submitting a job through torque/PBS, the head node also runs the
Moab scheduler, the .pbs file has this in the resources line :
#PBS -l nodes=2:ppn=4
I've also tried something like :
#PBS -l procs=56
and at the end of script I'm running :
