I wanted to install lammps parallel according to lammps sites’s instructions.
but after installing packages and run an example parallel I got this error:
It looks like MPI_INIT failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during MPI_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

This is an MPI problem, not a LAMMPS problem.
I suggest you find a local expert to help you.
Though as Steve said, though not related to the error you are having
I've attached a makefile I've been using which seems to work for me.
(I stole this makefile from the ubuntu forums. Copy it into the
I've read some ubuntu users complain about MPI problems after
upgrading from an earlier version of ubuntu. If it helps, I'm running
this on a fresh installation of ubuntu 11.10 (I had to install these
additional packages: mpich2, build-essential, fftw-dev, gfortran,
g++) Anyway, this works on a multi-core desktop. (I don't have a
cluster to test it on at the moment.)
