All built, looks like mips/mipsel had expired keys so will need a
reupload once that's sorted.

Failed (because mpqc was still built against lam, I think).  Should be

That would be very cool indeed! I had some chat with Jeff Squyres (Open

much hassle.[1]


I'll talk to Jeff. This had come up in another meeting last November and 
Jeff and I talked about doing this. But we never followed up on it; the 
problem is that this will require quite a few changes in one or both MPI 
implementations. More importantly, both MPICH2 and Open MPI have 
derivative implementations (Intel MPI, IBM MPI, Cray MPI, Microsoft MPI, 
MVAPICH2, etc., for MPICH2, and Sun MPI (renamed to Oracle MPI) for Open 
MPI) that we would need to coordinate with. This can potentially be a 
big change for them.


Also, there is some concern amongst MPI developers that we might need to 
break ABI compatibility once in a while. For example, we recently had to 
increase the value of MPI_MAX_ERROR_STRING, which breaks ABI 
compatibility, but was required. So, we need some sort of escape hatch 
to get around such issues.


I'll try to see what can be done, but no promises :-).

As Lucas already said, we're already happy with what MPICH2 provides.
But thanks for your offer!

Lucas, for this transition I will to fix the build systems, or at least
work around them. But we should get in touch after the release about
some MPI mini-policy.[2] I hope to have all patches working by the end
of the weekend, hopefully earlier.

Best regards,
Manuel

[1] Not that I'm for using proprietary stuff but I know some our users
do care for that. And so we should have that in mind. Getting to the
point where BLAS/LAPACK is (well, almost) would save us some serious
headaches. ;)

[2] There are a few more problems we do not have a solution for yet, but
getting rid of LAM and MPICH is one of the major blockers, IMHO.

Yes, sorry. Mpich2 provides enough configure options for us to put
the files where we want in any case. But since there's only a handful of
packages failing to build because of that, I still prefer to fix it in
the build system of those packages.

If we choose to do the first approach, what exactly needs to change in

Debian?



Still waiting for the day when MPI standardizes on ABI, not API… But
that may be wishful thinking.

Packages depending on MPICH2 are failing to build. This is not an issue
with MPICH2, but thanks for taking the time to look into it!

The problem is that a lot of build systems of MPI-using software want
the headers in $prefix/include and the libs in $prefix/lib, and on can
often only use $prefix to point to the location of MPI-relevant files.
The Debian package of MPICH2 uses $prefix/lib and $prefix/include/mpich2
which a lot of build systems do not like or handle correctly. This is
why the openmpi package uses --prefix=/usr/lib/openmpi to build and
symlinks the libraries to /usr/lib. This way, everything works as

Debian so far, or fix every broken build system out there. [0]

[0] Preferably, we would fix the build system. As far as Open MPI is
concerned, the /usr/lib/openmpi/{lib,include} hierarchy was requested by
a user since he had the very same problem.

We are currently using prefix=/usr and includedir=/usr/include/mpich2,

We could use includedir=/usr/lib/mpich2/include, but I'm still not sure

Ok, this is the part I didn't understand fully. Is MPICH2's build 
failing when includedir is specified as a different location? (I just 
tried that on my machine and it seems to work correctly for me.) Or did 
you mean some other package depending on MPICH2 is failing?

Hi Pavan,

Could you take a look at http://bugs.debian.org/573187 and at the
message below?

We would like to switch to using mpich2 on the arches where openmpi is
not supported, but some packages fail to build from source when using
mpich2. It seems that for some of them, it is caused by build systems
expecting to find mpi.h in /usr/lib/mpich2/include/ (as it is the case
for other MPI implementations), while it is shipped in
/usr/include/mpich2/.

This seems like something that would be better fixed upstream, even if I
agree that the file location in openmpi is a bit strange. What do you
think?

So, did you spend this time on doing fixes already? :-)

Yes, I indeed did. Not as much as I'd liked too, but nevertheless.


It would be great to see at least a few patches for the breaking
packages before the new defaults package is uploaded.

I'll just repeat the list of failing packages here and comment on them
group-wise.

Patch available:
  * rmpi: patch attached
  * blacs-mpi: patch attached
  * mumps: Can be rebuild against fixed blacs-mpi

CMake:
  * igstk
  * kwwidgets
CMake does some magic here which I do not understand yet. These seem to
fail because they look for a library openmpi provides but mpich2
doesn't. (Well, at least not under that name.) We might fix that via a
symlink in mpich2, or I've to dive deeper into CMake.

Wrong location of header file (mpi.h) at configure:
  * apbs
  * petsc: almost done, minor issue remaining
There may be more packages in this group, the already patched ones are
also of this type. Most upstream build systems seem to expect
a /foo/{include,lib} hierarchy, and you can only pass the location
of /foo to the build system. Some are flexible enough to work around
that (see patches) but I do not see how to do that for apbs easily.
(It's possible for petsc but my patch has some other issue I have to
track down.) This could easily be fixed it mpich2 would provide this
hierarchy, as we already discussed. It would make the patches much
simpler, some packages of these 11 wouldn't even need patching then. I
think we should reconsider the option of doing the change in mpich2.
(Note: MPICH and LAM did provide this hierarchy, too.)

Remaining packages:
  * life: Might be fixed with petsc, not sure yet.
  * gdcm: Not looked at yet
  * pgapack: Not looked at yet
  * scalapack: Seems to be of type "wrong location", may need no fix

This is the status as of now. I'm working on the remaining patches, but
the proposed change to mpich2 would save us some time here, as it avoids
patching about half of the packages at all. Please let me know what you
think about that.

Best regards,
Manuel

Bug#573187: transition: mpi-defaults

2010-04-06 Thread Lucas Nussbaum
Hi Pavan,

Could you take a look at http://bugs.debian.org/573187 and at the
message below?

We would like to switch to using mpich2 on the arches where openmpi is
not supported, but some packages fail to build from source when using
mpich2. It seems that for some of them, it is caused by build systems
expecting to find mpi.h in /usr/lib/mpich2/include/ (as it is the case
for other MPI implementations), while it is shipped in
/usr/include/mpich2/.

This seems like something that would be better fixed upstream, even if I
agree that the file location in openmpi is a bit strange. What do you
think?

Am Montag, den 05.04.2010, 17:22 +0200 schrieb Marc 'HE' Brockschmidt:

Yes, I indeed did. Not as much as I'd liked too, but nevertheless.

I'll just repeat the list of failing packages here and comment on them
group-wise.

Patch available:
  * rmpi: patch attached
  * blacs-mpi: patch attached
  * mumps: Can be rebuild against fixed blacs-mpi

CMake:
  * igstk
  * kwwidgets
CMake does some magic here which I do not understand yet. These seem to
fail because they look for a library openmpi provides but mpich2
doesn't. (Well, at least not under that name.) We might fix that via a
symlink in mpich2, or I've to dive deeper into CMake.

Wrong location of header file (mpi.h) at configure:
  * apbs
  * petsc: almost done, minor issue remaining
There may be more packages in this group, the already patched ones are
also of this type. Most upstream build systems seem to expect
a /foo/{include,lib} hierarchy, and you can only pass the location
of /foo to the build system. Some are flexible enough to work around
that (see patches) but I do not see how to do that for apbs easily.
(It's possible for petsc but my patch has some other issue I have to
track down.) This could easily be fixed it mpich2 would provide this
hierarchy, as we already discussed. It would make the patches much
simpler, some packages of these 11 wouldn't even need patching then. I
think we should reconsider the option of doing the change in mpich2.
(Note: MPICH and LAM did provide this hierarchy, too.)

Remaining packages:
  * life: Might be fixed with petsc, not sure yet.
  * gdcm: Not looked at yet
  * pgapack: Not looked at yet
  * scalapack: Seems to be of type "wrong location", may need no fix

This is the status as of now. I'm working on the remaining patches, but
the proposed change to mpich2 would save us some time here, as it avoids
patching about half of the packages at all. Please let me know what you
think about that.

Best regards,
Manuel

So, did you spend this time on doing fixes already? :-)

It would be great to see at least a few patches for the breaking
packages before the new defaults package is uploaded.

Sure. It might need some severe patching, though.

I do not see why it should. It's only relevant a compile time. The real
libs are in /usr/lib, where the linker will find them later, and rpath
is not involved. (The openmpi package has used that setup since
forever.)

Anyway, I'm OK with patching the rules file as well. Time spent on
arguing can be better spent elsewhere. ;)

Given the low number of packages that FTBFS with mpich2 as mpi-default,
I would say that this could be fixed in the failing packages' build
system, no?

"Fixing" that my providing symlinks might cause subtle failures later,
when the package is actually used and thinks that the libs are in some
place while they aren't.

No problem, same here!

I do not have everything sorted out yet but the issues seem to arise
from broken assumptions on where MPI stuff may reside. This is trivial
to fix in some cases and harder in others.

As an example, apbs expects {include,lib} in the same directory, which
is not the case for mpich2 currently. Lucas, do you think we should
"fix" this by providing this layout in the MPI -dev packages
under /usr/lib/{openmpi,mpich2}/? It seems that apbs is not the only
package assuming this but I did not generate numbers on that. It might
be worth to have some consistency here nevertheless, IMHO.

That would be great. The point is that transitions suck most once they
are half-started and preparing as much as possible helps to keep the
sucking phase short.

I'm with Lucas here. If we file the bugs before the upload, we should be
very explicit about the fact that it does not concern unstable yet. As a
compromise, we could prepare patches, upload mpi-defaults and file the
bugs with the respective patches. (Or most of them, did not check how
complex the changes are.) This would enable to fix these in a timely

As for user-tagging, we can use the old-mpi-eol usertag.

Erm. I'm very reluctant to filing bugs that can't easily be reproduced
in unstable. At this point, you need a custom mpi-defaults package to
reproduce them. Also, it is possible that some of them will not be
fixable before the new mpi-defaults is in unstable (= you can't upload a
fixed package that works if the new mpi-defaults isn't in unstable).

Could bugs about these issues be filed (with a usertag, so we can track

Good to know, thanks for your work.

I would propose that all (or at least) most of these bugs should be
fixed before we actually do the switch in unstable. Manuel, does that
seem OK to you?

Bug#573187: transition: mpi-defaults

2010-03-17 Thread Lucas Nussbaum
Hi,

As asked during yesterday's release team meeting, I did a partial
archive rebuild on amd64 with a modified mpi-defaults pointing to mpich2
instead of openmpi. The goal is to detect issues that will show up when
the slower arches are switched to mpich2. (I know the plan is not to
switch amd64 to mpich2)

After searching for /mpi/ in build-depends and depends, I rebuilt the
following 118 packages: advi apbs apron ara arpack
avant-window-navigator blacs-mpi blitz++ boost-defaults boost1.40
boost1.42 bytecode camlp5 ccsm coccinelle code-saturne

The following 11 packages failed to build:
apbs looks for mpi.h in the wrong place
blacs-mpi missing target 'build-mpich2' in debian/rules
gdcm ?
igstk No rule to make target `/usr/lib/libmpi_cxx.so' (?)

pgapack cd: 4: can't cd to lib/linux/
rmpi configure: error: "Cannot find mpi.h header file"
scalapack missing target 'build-mpich2' in debian/rules

So, it looks like it is mostly build system bugs, and it should not be
too hard to fix.

Bug#573187: transition: mpi-defaults

2010-03-09 Thread Manuel Prinz
Package: release.debian.org
Severity: normal
User: release.debian@packages.debian.org
Usertags: transition

Dear release team,

as requested by Marc Brockschmidt in <87ocj81kt4@solon.marcbrockschmidt.de>,
I file this bug for the mpi-defaults transition.

As discussed on the Debian Science list, we'd like to get rid of two old
MPI implementations, MPICH (mpich) and LAM/MPI (lam4). Both are not
maintained upstream anymore and have successors already in the archive,
MPICH2 (mpich2) and Open MPI (openmpi), respectively.

The current plan is to EOL MPICH and LAM by removing all reverse
dependencies on those packages. One big step in this direction would be
via mpi-defaults. The current version depends on LAM/MPI for arches
where Open MPI is not supported (yet). A package is prepared that will
depend on MPICH2 on these arches. After uploading that, binNMUs are
needed for the depending packages.

This transition will interfere with the hdf5 transition, as hdf5 does
build MPI-enabled versions.

Bugs have been filed for the remaining packages that do not use
mpi-defaults but depend on an MPI implementation directly. The can be
tracked via [1]. They need to be fixed by sourceful uploads, I only
mention them for reference.

If you have any questions, feel free to ask on the Debian Science
mailing list. And sorry for bringing it up so late in the release
cycle!

Best regards,
Manuel
