Okay, here goes a start:

Category: Platform Specific Questions | Debian/Ubuntu

$q[] = "Which Debian Open MPI packages do I need?";

$anchor[] = "debian-package-contents";

$a[] = "That depends on your use of Open MPI. If you are running a
pre-compiled MPI binary in one process, you simply need [libopenmpi1].
To launch jobs in multiple processes, you need [openmpi-bin], which
includes [orted], [orterun] (_a.k.a._ [mpirun]), and [ompi_info]. To
compile programs, you need [libopenmpi-dev], or if you need debugging
symbols, then [libopenmpi-dbg] with debugging symbols.<p> Note: if you
install, or have ever installed, mpich and/or lam packages, please be
sure you use [update-alternatives] to make sure that the \"[mpi]\" and
\"[mpirun]\" symlinks point to the Open MPI entries.";

$q[] = "How do I run Open MPI programs in a Debian chroot environment?";

$anchor[] = "debian-chroot-broken";

$a[] = "As of version 1.2.7, this does not work; see " .
aurchin_click("http://bugs.debian.org/494046") . "Debian bug
494046</a>.";

$q[] = "Is Ubuntu Linux a supported platform?";

$anchor[] = "ubuntu";

$a[] = "Unofficially, there are Open MPI packages in the Ubuntu
\"universe\" package section. Unfortunately, the packages in 8.04 LTS
Hardy Heron are buggy, so you should either get packages from Debian
Lenny or compile Open MPI yourself.<p> In general, Ubuntu gets its
\"universe\" packages from Debian unstable at a time set by their
release schedules, a time generally not known to the Debian package
developers, so the quality of the Ubuntu packages is generally not as
good as that of the packages in a Debian release.";

Dirk, any comments?
