Dunno. Do lower np values succeed? If so, at what value of np does
the job no longer start?
Perhaps it's having a hard time creating the shared-memory backing file
in /tmp. I think this is a 64-Mbyte file. If this is the case, try
reducing the size of the shared area per this FAQ item:

Sorry, I forgot to give more details on what versions I am using:

Hello list,
I am running a job on a 4 quadcore AMD Opteron. This machine has 16 cores,
which I can verify by looking at /proc/cpuinfo. However, when I run a job
with
mpirun -np 16 -mca btl self,sm job
I get this error:

I tried this and it still crashes with openmpi-1.4. Is it supposed to
work with openmpi-1.4
or do I need to compile openmpi-1.4.1 ?
Terribly sorry, I should checked my own notes thoroughly before giving
others advice. One needs to give the dynamic rules file location on the
command line:
It's almost midnight here, so I left home, but I will try it tomorrow.
There were some directories left after "make uninstall". I will give more
details tomorrow.
Thanks Jeff,
Andreea

I don't know what else should I try... because it worked on 1.3.3 doing
exactly the same steps. I tried to install it both with an active eth
interface and an inactive one. I am running on a virtual machine that has
CentOS as OS.
Any suggestions?

I have done this according to suggestion on this list, until a fix comes
that makes it possible to change via command line:
To choose bruck for all message sizes / mpi sizes with openmpi-1.4
File $HOME/.openmpi/mca-params.conf (replace /homeX) so it points to
the correct file:
coll_tune

This is especially dangerous because the Open MPI lists munge the

I tried the new version, that was uploaded today. I still have that error,
just that now is at line 405 instead of 399.
Maybe if I give more details:
- I first had OpenMPI version 1.3.3 with BLCR installed: mpirun,
ompi-checkpoint and ompi-restart worked with that version.
- I wanted to update to
On my machine I need to use dynamic rules to enforce the bruck or pairwise
algorithm for alltoall, since unfortunately the default basic linear
algorithm performs quite poorly on my
Infiniband network. Few months ago I noticed that in case of VASP,

Hi Charlie,
Glad to hear that you compiled it successfully.
The error you got with 1.3.4 is a bug that the CMake script didn't set
the SVN information correctly, and it has been fixed in 1.4 and later.
Thanks,

Hi...
still not working. Though I uninstalled OpenMPI with make uninstall and I
manually deleted all other files, I still have the same error when
checkpointing.
Any idea?
