Current meaning 1.6.1, 1.9, 1.7,???

The root cause is that you didn't specify an executable to run.
However, we might have some help messages missing, too. What version of OMPI
are you running?

All,
I am quite new to using Open MPI as it is required by programs that I
use for research. While running a chemistry program through Terminal, I
inadvertently hit enter after I tried to run the program over multiple
processors and am now getting one of two errors when I try and run th

Thanks, Ralph,
the new syntax works well (I used "man mpirun", which displayed the old
syntax).
Also, the report displayed by --report-binding is far more human-readable
than in previous versions of OpenMPI
Out of curiosity, and also to supress the warning, I installed the
libnuma-dev package wit
You are using cmd line options that no longer exist in the 1.9 release - look
at "mpirun -h" for the current list of options.
FWIW: in your example, the correct cmd line would be:
mpirun -np 2 --bind-to core -map-by core --report-bindings uptime
Note the space in "--bind-to core" and the "-map-
Hi,
I have one more question.
I wanted to experiment with processor affinity command-line options on my
ubuntu PC.
When I use OpenMPI compiled from sourecs a few weeks ago, mpirun returns
error messages.
However, the"official" OpenMPI installation on the same machine makes no
problem.

Hi, Gus and John,
my code (zeusmp2) is a F77 code ported in F95, and the very first time
I have launched it, the processed disappears almost immediately.
I checked the code with valgrind and some unallocated arrays were
passed wrongly to some subroutines.
After having corrected this bug, the code
Apologies, I have not taken the time to read your comprehensive diagnostics!
As Gus says, this sounds like a memory problem.
My suspicion would be the kernel Out Of Memory (OOM) killer.
Log into those nodes (or ask your systems manager to do this). Look
closely at /var/log/messages where there wil
