I'm way behind on my mail; apologies for the delay in replying.
Did you figure this out?
As a pure guess, it sounds like you have a heterogeneous setup --
nodes have different distros and/or versions. As such, your glibc's
may be different, etc. In such situations, it is definitely
recommended to have a separate installation of Open MPI *on each node*
(i.e., compiled/built for that distro/version/platform).
If you're copying the files from system A to system B and A and B are
different distros/versions, it could be a good reason why it fails to
work.
Hope that helps.

Hi everyone,
I am trying to build my own system for my nodes - minimalistic. I
tried
to make things easy so I didn't even recompile openMPI for it, I just
copied everything from my Ubuntu installation (I know, it's very
dirty,
but I stick to KISS :) ). Before, things just worked perfectly with
the
libraries. I only recompile executable binaries, not Glibc (not
openMPI,
I also didn't succeed compiling openMPI but that's a different story).
So, as I keep trying to run Hello world! program, I keep getting the
same error message every time. Everything in the system is fine from
my
point of view. The error message is this:
[user:24307] mca: base: components_open: component timer / linux open
function failed

It looks like opal_init failed for some reason; your parallel
process is
likely to abort. There are many reasons that a parallel process can
fail during opal_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):
opal_carto_base_select failed
--> Returned value -13 instead of OPAL_SUCCESS

I tried googling and searching the archives, nothing gave me a hint.
What might be missing? Should I really try to recompile openMPI? What
needs to be on/off in the kernel? Any ideas?
Thanks in advance,
bremby
