I know that we are sometimes a little slow to answer user emails, but you need to give us more than a few hours to answer before re-posting your mails. :-)

If you want to see if there are easy fixes to why 1.4.x and/or 1.6.x fail to compile, see this page: Send all the info listed on that page.

We say something quite similar in the (1.6.x) README file:

When verifying a new Open MPI installation, we recommend running three

1. Use "mpirun" to launch a non-MPI program (e.g., hostname or uptime)
   across multiple nodes.

2. Use "mpirun" to launch a trivial MPI program that does no MPI
   communication (e.g., the hello_c program in the examples/ directory
   in the Open MPI distribution).

3. Use "mpirun" to launch a trivial MPI program that sends and
   receives a few MPI messages (e.g., the ring_c program in the
   examples/ directory in the Open MPI distribution).

If you can run all three of these tests successfully, that is a good
indication that Open MPI built and installed properly.

Wow; configuration / compilation of Open MPI took *3 hours*? I'm guessing you have very old / low-power processors, or very slow network filesystem access...?

See this FAQ information on where to install OMPI:

It likely won't be approved. Send a smaller attachment, please, such as a compressed text file (see the support page, above). :-)
