[openfabrics-ewg] OpenMPI package

[Jeff Squyres (jsquyres)]

Several issues:

1. Since I am just entering this effort, I downloaded RC2 yesterday and
poked around inside for details on how Open MPI will need to be
packaged.  I sent an off-list mail to Tziporet last night asking a bunch
of technical questions (I probably should have sent this on-list,
sorry).  Here are the main questions from that e-mail:

- I downloaded RC2.  It looks like you are distributing source and have
some scripts to build RPMs and install the RPMs.  Is that correct / the
goal of IBED?

- The README appears to be quite out of date; I assume you will need
some Open MPI-specific information for it.  How should I get this to
you?

- It looks like the LICENSE file is incomplete -- shouldn't it contain
at least references to the license / copyright information of the
sub-packages?  (e.g., MVAPICH and others) 

- I see a bunch of top-level *.sh scripts -- these will need to be
expanded for Open MPI.  Who does that -- me or you?

- I see SOURCES/mpi_osu...tgz.  That contains a bunch of scripts and the
mvapich tarball.  I'm assuming that Open MPI needs to be bundled this
way as well...?  Is this documented anywhere?  Is there a reason why a
tarball contains another tarball?

- The mpi_osu...tgz file contains several MPI-independent utilities
(PMB, prestal, etc.).  Should these be moved out of the OSU MPI tarball
and into an MPI-agnostic tarball, and then compiled against each MPI
that is installed?

- What is the plan for having 2 MPIs in this distribution -- how will
users/sysadmins choose between them?  I.e., are we going to allow both
to be installed and make it a user-level decision which to use?  Or will
the sysadmin only pick one to install?  Or ...?

2. Some more questions that I did not include in my mail last night:

- Is there a source code repository for IBED somewhere?  What is the
model for developers to modify / test IBED?

- What version of MVAPICH is being used?  I see
mvapich-0.9.5-mlx2.0.1.tar.gz -- does this mean it's Mellanox's v2.0.1
of MVAPICH 0.9.5?  Are other vendors allowed to modify this?  (I ask
because all of our MVAPICH's are slightly different -- fixed bugs
specific to our customers, etc.)

- There appear to be multiple levels of indirection in the MVAPICH build
scripts -- what directory --prefix is it being installed to?  (this is
going to be influenced by the answer to the "2 MPI" question, above)

3. I would like to use Open MPI v1.0.2 for the IBED release (Gleb is on
the Open MPI mailing lists and probably saw me send that intention to
the Open MPI team yesterday).

4. Gleb sent me a proposed spec file for Open MPI -- we'll iterate about
this off-list.
