Hi,
Thank you so much. Well, the memory is enough. As I said, the jobs run
and the whole process is actually done without complaining about memory,
but they are not ended up correctly. I first tries to solve this using
this algorithm:
1. all processes except root will wait before MPI_Finalize

You'd probably see the same problem even if you strdup'ed the c_str()
and system()'ed that.
What kernel are you using? Does OMPI say that

This looks like you have two different versions of Open MPI installed
on your two machines (it's hard to tell with the name
"localhost.localdomain", though -- can you name your two computers
differently so that you can tell them apart in the output?).
You need to have the same version of
Joe,
You are correct this is a ROCKS cluster. I didn't use the the --sge option when
building (I tend to stay more generic, but I should have done that).
Not sure of the OFED release but I don't admin this cluster and the owners are
