I had the following strange problem.
I don't know if it is due to redhat or lam or ssh.
Looking through the archive I have the feeling that some other people had
the same problem before me and maybe they did not realize what happened.
I compile my code on a dual-processor redhat system
and upload it to a redhat cluster in order to run it.
I got error message
``...mpirun did not invoke MPI_INIT before quitting...''
due to programming error.
This is no big news, but the message stayed even after recompiling and
uploading a previously working version.
Only renaming the executable solved the problem.
It looks like that the OS (or lam) remembers the name of the
incorrect executable and does not want to accept it anymore as correct.
This is freaky.
I renamed the file back and forth with the same result.
