FWIW: I have fixed this on the developer's trunk, and Jeff has scheduled it for
release in the upcoming 1.6 release (when 1.5 series rolls over). I don't
expect we'll backport it to 1.4 unless someone really needs it there.
Thanks!

Hi Frank, Lloyd
If all you want is to sort out from which process the output is coming from,
you can use the "-tag-output" switch to the [OpenMPI] mpirun.
Check it out with 'man mpirun'.
I hope this helps,

I think we need to add something to the FAQ so that it's googleable "The Intel
12.1 Linux compilers before 12.1.2 are busted. Upgrade to at least 12.1.2, and
OMPI should compile and work fine."

Hi Götz,
I don't know whether we can implement your suggestion; it is dependent
on the terms of our license with Intel. I will take this under
advisement. Thank you very much.

Hi Jeff,
Pending further testing, your suggestion seems to have fixed the
issue. Thank you very much.

Great, that works!! Many Thanks!

Ah - crud. Looks like the default-hostfile mca param isn't getting set to the
default value. Will resolve - thanks!

Sure:
reuti@pc15370:~> mpiexec --display-allocation -np 4 ./mpihello
== AL
Try out the attached wrapper:
$ mpiexec -np 2 masterstdout
mpirun -n 2
Is there a way to have mpirun just merger STDOUT of one process to its
STDOUT stream?

Could you add --display-allocation to your cmd line? This will tell us if it
found/read the default hostfile, or if the problem is with the mapper.

I don't know about using mpirun to do it, but you can actually call
mpirun on a script, and have that script individually call a single
