I see that you also posted to the admin list as well; I will reply here.

You must subscribe to OMPI lists before posting to them (this post
was sent to ompi-docs-owner_at_[hidden]). Hence, if you reply to
this post before subscribing, it will be automatically discarded.
Sorry; this is a necessary anti-spam control for the modern internet...

This docs subgroup was just formed to create a comprehensive user-
level guide to Open MPI. So the effort is just starting. Most of
our current documentation consists of man pages and the web page
FAQ. This is not really enough, as you note -- we're working on it,
but it'll take a little while.

However, the principles of Open MPI are quite similar to LAM/MPI.
One notable difference is that there is no lamboot/lamhalt. You just
use the wrapper compilers (mpicc, mpif77, etc.) to compile your MPI
program and then use mpirun or mpiexec (both are exactly equivalent
in Open MPI) to run them. There is a man page for mpirun/mpiexec;
that should get you going.

You might want to send future questions to the general user's mailing
list; see this page for a description of OMPI's mailing lists:
