I modified the patch (it missed a few places, some minor changes in
implementation, etc) and committed it to the developer's trunk. I'll check with
the release managers to see if this is something they want in the 1.4 series,
or if they would rather defer it to the 1.5 series due out soon.

Dear All,
I am facing very wierd results of OpenMPI 1.4.1 on Amazon EC2. I have
used Small Instance and and High CPU medium instance for benchmarking
latency and bandwidth. The OpenMPI was configured with the default
options. when the code is run in the cluster mode the latency and
bandwidth of
Okay, thanks. It's the same problem as the other person encountered. Basically,
it looks to OMPI as if you are launching > 128 independent app contexts, and
our arrays were limited to 128.
He has provided a patch that I'll review (couple of things I'd rather change)
and then apply to our develo
Hi!
Does anyone knows how to compile LAMMPS code with openMPI? Can you please post
the exact detail of installing
it in ubuntu 9.10 os.
Thanks.

Hi,
the program is executed as one application on 129 cpus defined by the
hostfile.
Than rank 0, inside the code, execute another program with 129 cpus, with a
one-to-one relation, rank0 of the spawined process runs on the same host of
rank0 of the spawning one and so on...
Excuting the spawning p

Since another user was doing something that caused a similar problem, perhaps
we are missing a key piece of info here. Are you launching one app_context
across 128 nodes? Or are you launching 128 app_contexts, each on a separate
node?
