Description (last modified by )
The new atlas release now builds netlib lapack itself, so the lapack tarball is now included in the ATLAS spkg.
 Updated to newest upstream source, various patches are no longer required
SAGE_ATLAS_LIB=path
now searches inpath/libatlas.so
instead ofpath/lib/libatlas.so
so it works for people with atlas in/lib64
, too. Threading is now enabled by default
 Flush before
os.system
(#13210)
Upstream has made some attempt at changing the layout of the shared libraries, which is now different from the static libraries. The atlas spkg contains a stub autoconf/libtools project that unpacks the static libraries and repacks them into equivalent shared libraries.
By default, ATLAS will now try twice to get timings and fail immediately if throttling is enabled. If autotuning fails build with SAGE_ATLAS_ARCH=fast
, and if that fails with SAGE_ATLAS_ARCH=base
. On x86, the fast and base targets are the new ATLAS generic targets x86SSE3 and x86SSE2/x86x87.
The updated cvxopt spkg fixes a blas path issue on Darwin.
The current spkg version is at
http://www.stp.dias.ie/~vbraun/Sage/spkg/atlas3.10.0.spkg http://www.stp.dias.ie/~vbraun/Sage/spkg/cvxopt1.1.5.p1.spkg
Apply trac_10508_root_repo.patch to the SAGE_ROOT repository and 10508_doctest.patch, trac_10508_update_atlas_docs.patch to the Sage repository.
Remove the lapack and blas packages.

Yes, the lapack spkg can be removed.

BLAS can also be removed if we go with this. f2c which was used before we got ATLAS to provide cblas by f2cing the BLAS package should also be removed (I think it listed in scipy's dependency only).

This fails because ATL_NCPU
is not set. Do you have a singlecore processor? I guess the threaded libraries are not built in that case.

yes, it's singlecore. An old Pentium M. (Atlas 3.8 spkg does not build on it, at all)

I changed the spkginstall
to make only singlethreaded shared libraries if necessary. Should work now.
For simplicity, I made spkgs for cvxopts and sage_scripts. So you need to add
http://www.stp.dias.ie/~vbraun/Sage/spkg/atlas3.9.32.spkg http://www.stp.dias.ie/~vbraun/Sage/spkg/cvxopt1.1.3.p0.spkg http://www.stp.dias.ie/~vbraun/Sage/spkg/sage_scripts4.6.1.alpha3.p0.spkg
to $SAGE_ROOT/spkg/standard
and then
 replace
spkg/install
with the attached version (Note thatsage_scripts
overwrites this file during installation, aargh)  replace
spkg/standard/deps
with the attached version.
I'm still having doctest errors with linbox...

I do not know how many of them are Atlas related, though. The log is here: http://boxen.math.washington.edu/home/dima/tmp/testlongatl3.9.log
comment:12 followup: ↓ 13 Changed 10 years ago by
A lot of it is probably related. Was this a build from scratch? linbox calls seem to be particularly affected, there are a lot of failures in that path: sage.matrix.matrix_integer_dense.Matrix_integer_dense._charpoly_linbox stuff going through: sage.matrix.matrix_rational_dense.Matrix_rational_dense.right_kernel is also affected and that smells like atlas at work too.
I must say we have observed a number of failures related to ATLAS3.9.23 in sageongentoo: https://github.com/cschwan/sageongentoo/issues#issue/3 you have failure there too but not due to iml/ATLAS as far as I can see. https://github.com/cschwan/sageongentoo/issues#issue/6 more subtle. I see you have the failure with devel/sage/sage/finance/time_series.pyx you may want to look the comment I wrote about it in the section "known test failures for Sage on Gentoo": https://github.com/cschwan/sageongentoo/wiki/Knowntestfailures note that sageongentoo can use (c)blasreference, ATLAS or gslcblas or some combinations  in fact amd and intel libraries could in principle be used but no one I know has tried. http://www.gentoo.org/proj/en/science/blaslapack.xml
Not sure about the SIGFPE, it could come from a result rounded to 0 or the like.

yes, it's a build from scratch, on the same machine (old Pentium M) as already discussed above.

I wonder if these are Atlas bugs, or Linbox bugs...
One should try an OSX build.

I had forgotten about that. I checked the spkg and ATLAS is not built on cygwin and OS X. So it makes sense.

I get the same doctest errors. Most of them are linbox related. The SIGFPE is from converting a NAN into a GMP integer, but I haven't gotten to the root of the NAN yet. In trying to debug this I've noticed that there are a bunch of valgrind warnings in the linbox code path we are using. I've asked some more specific questions on the linboxuse mailinglist:
https://groups.google.com/d/topic/linboxuse/N3QNNOQuTAc/discussion
But so far no final conclusion.

Was your successful build using these parameters? I had in one instance a nonworking ATLAS because the cpu type was misdetected (wanted to use sse3 when it didn't have them). The build was curiously successful but the library was unusable.

The processor is Pentium M Banias 1.1GHz, http://ark.intel.com/Product.aspx?id=27600 (according to GotoBlas? installation procedure :))
The Atlas built is not totally useless, it works for many doctests. By the way, 3.8 also thinks it's a CoreDuo?. And it works. I saw somewhere a note that it's OK.

Converting a NAN into a GMP integer is exactly what was happening in https://github.com/cschwan/sageongentoo/issues/3 and it didn't happen when using gslcblas. I will do a full build of sageongentoo with 3.9.40 (or 41) and see if I can see anything.
comment:21 Changed 10 years ago by
Yuck, still got problems leading to linbox, I got the ones leading to iml too. Note that using another cblas like gslcblas/openblas/reference(netlib) all these problems disappear which seem to indicate that there is something going on in ATLAS itself or that all the others gets it wrong (I realise that on a stock sage you may have trouble compiling iml with anything else than ATLAS, it requires some patching to the configure script to be able to do so).
comment:22 Changed 10 years ago by
It may be worth noting that new released are available for both stable and development:
http://sourceforge.net/projects/mathatlas/files/Stable/3.8.4/Stable http://sourceforge.net/projects/mathatlas/files/Developer%20%28unstable%29/3.9.41/Unstable
comment:23 Changed 10 years ago by
I have 3.9.41 now, the only difference was it compiled faster because there was tuning for my cpu. But we could investigate 3.8.4. Thanks for pointing it is out, some of us (me at least) didn't think it would ever happen. We may have a stable ATLAS supporting newer CPUs at last, and it looks like I could test it quickly.
comment:24 Changed 10 years ago by
OK 3.8.4 doesn't suffer from any of the drawbacks that are apparent in 3.9.23+.
The big drawback is that it doesn't build lapack nicely on its own, provided we point to the sources like the latest 3.9.xx do. That means spkginstall would need a little bit more work.
Opinions?
comment:25 Changed 10 years ago by
Can we keep this ticket focused on the development version of atlas and discuss the stable ATLAS on #10226? I updated the spkg on the latter ticket to the new stable ATLAS release.
comment:26 Changed 10 years ago by
Sure. My current opinion and that's something I am pushing to sageongentoo users is to avoid ATLAS 3.9.xx for the time being. It is possible that ATLAS3.9.xx is doing something permissible that iml and linbox are not ready to catch. My line of thought is that I remember that some algorithm in iml takes the inverse of a result returned by cblas. If the result is 0 instead of a small value we may have our NaN, more likely some result from ATLAS is a NaN.
comment:27 Changed 10 years ago by
 Cc leif added
Note that you can copy updated spkgs into spkg/standard/
and then do
env SAGE_UPGRADING=yes make build
to rebuild all dependent packages.
(We should perhaps add make
targets for that to the toplevel Makefile and document them in the Developer's Guide, as this is currently just a sideeffect of the effort to make upgrading work.)
If you at the same time need to apply patches to the Sage library, things get a bit more complicated, as e.g. Sage switches to the main
branch before reinstalling the Sage library package. One safe way is to first apply the patches, create a new sagex.y.zwhatever
spkg (with devel/sage/spkgdist
) and replace the one in spkg/standard/
with that one (or at least make sure newest_version
will pick up the right one).
Note that the extension modules' dependencies in module_list.py
are currently far from complete. #8664 adds some in a generic way by adding them automatically in setup.py
, i.e. lets modules also depend on the headers of the libraries they use (which [only] works if the headers' mtimes get modified / updated during installation of their corresponding libraries). The dumb alternative is to run sage baforce
after an "upgrade" process.

 I haven't checked but I am quite sure from other reports that cblas_dgem{m,v} is still buggy (someone posted that R built against that Atlas lapack was giving them trouble and R upstream pointed the finger to Atlas).

I don't have any strong opinion on where to put the lapack tarball, except that our convention of only allowing a single src/
directory is shortsighted.
Note that I'm not using assertions for control flow, i.e. I'm not using
try: <command> except AssertionError: <alternative>
Note that you could theoretically also catch the SystemExit
exception, so sys.exit()
isn't different from assert
in that regard. I'm only using assertions to ensure the following contract holds: spkginstall
completes successfully only if the relevant atlas configure/make completed with rc==0
I'll replace the asserts by something that returns rc as exit code, though.

I think (IMHO but I might be wrong) that assertions should be used only in a situation where an assertion being false indicates a bug in the program. If rc != 0
in spkginstall
, that is an ordinary error condition, not a bug in the spkginstall
script.

The new spkg will attempt to build on OSX if SAGE_ATLAS_ARCH

I also am planning to allow SAGE_ATLAS_LIB=system
and use ldconfig p
to get the system atlas, if available. Though perhaps we should do that in a later version. This spkg seems to fix some build issues that people reported on the sage mailinglists so it might be good to get it in sooner rather than later.

In spkginstall
, I find it confusing that you have a function build()
which calls configure()
and make_atlas()
.
I would get rid of build()
and simply call configure()
and make_atlas()
directly.

About SAGE_FAT_BINARY
: at one point you are checking
os.environ.has_key('SAGE_FAT_BINARY')
and at another you are checking
os.environ.get('SAGE_FAT_BINARY', 'no') == 'yes' and conf['Intel?']
I think the correct check is
os.environ.get('SAGE_FAT_BINARY', 'no') == 'yes'
"SAGE_FAT_BINARY" has evolved to mean "build a generic binary on any processor", so it's not Intel specific anymore. Just call configure_base()
.

I've noticed before that the build time for the "generic" binary is rather long. Its not entirely generic, it is still doing timing for cache edges. But the result will be a working library, it won't probe funky asm implementations that other CPUs might not support. I'll ask on the ATLAS mailinglist for clarification.

I can beat that:

on an otherwise idle machine, an AMD Fusion E450 running Ubuntu 10.04.4 LTS x86_64.)
It took far more time than building all of Sage [in parallel, on that dualcore CPU], including the old ATLAS spkg. I currently have no figures for a separate ATLAS 3.8.4 build, but the timings from previous parallel Sage builds on that machine vary between
real 214m52.096s user 175m5.390s sys 9m56.210s Successfully installed atlas3.8.4.p1
and

(The LAPACK and BLAS spkg build times in these builds are a few minutes and less than one minute [wall time], respectively.)
I was actually hoping ATLAS 3.9.x / 3.10 meanwhile "knows" these AMD CPUs and therefore builds at least a bit faster...

If I set SAGE_ATLAS_ARCH=Corei2,AVX,SSE3,SSE2,SSE1 then I can also compile atlas3.10.0 in about 10 minutes. The issue is only with the "generic" archdefs, which seem to be not sufficiently specialzied. I've raised this issue on the ATLAS mailinglist.
comment:68 Changed 9 years ago by
The updated atlas spkg also installs a script atlasconfig
in $SAGE_LOCAL/bin
which can be used to compute new architectural defaults. I need somebody on Linux i386 to first install the new spkg and then run
SAGE_FAT_BINARY=yes atlasconfig archdef
to grind out the archdefs for the i386 "generic" target. I'm currently doing this for x86_64, but I don't have a i386 machine. This will use sudo to turn off CPU throttling so you need to be a sudoer.

The new version d33e9114156d8373fa61f957b379e029 changes the "fast" 64bit archdef to P4E64SSE3
.
It turns out that there are no 64bit generic archdefs, which might have been one reason for why ATLAS was slow to compile. The SPKG uses the existing 32bit archdefs or the 64bit one that I made. On x86 the spkg should produce a working ATLAS library within 1030 mins, and only go through the tuning process if either
 CPU throttling is disabled (
scaling_governor=performance
, needs root), or  SAGE_ATLAS_ARCH is explicitly set to something different from "base" / "fast".

Well, there's at least room for nitpicking (a couple of typos and some inconsistencies as well as superfluous code in spkginstall
and probably configuration.py
, don't recall)... I'll maybe take a look at it again tomorrow, and probably provide a patch (provided Volker doesn't plan to make further major changes to these files).
How about also installing a user script for convenience to save the built ATLAS libraries to another place (for later use with SAGE_ATLAS_LIB
)?
Regarding the mentioned excessive tuning times, I also wonder whether we should use something like SAGE_ATLAS_ARCH=fast
(or base
) by default, i.e., only do selftuning if the user explicitly asks for it in some way. I guess the Sage Installation Guide needs to get updated anyway w.r.t. ATLAS and environment variables.

 Leif, are you working on a patch? In
configure_fast()

 Francois: the weird messages are normal. The rpaths are set by libtools and are what libtools likes to set. As long as we set
LD_LIBRARY_PATH
this doesn't matter except when we distribute the binaries. This needs to be fixed some day in all shared libs but not on this ticket.

But after sys.exit(512)
, Python has return code of zero, on sage.math, OS X, and OpenSolaris. So sagespkg thinks the spkg installed correctly, which it clearly didn't. From the documentation for os.system, it looks to me that its output should be divided by 512 to get a return code suitable for sys.exit, but I'm not sure about that. However you want to fix it, it has to be changed: it's not acceptable for the compilation to fail but for spkginstall to have a return code of zero.

Sure. Although ATLAS currently consumes only <= 9W ;)
Unfortunately ATLAS is built quite late (due to its odd dependency on Sage's Python  while your script is apparently designed to support Python 2.4 as well), so a fair amount of the time spent building Sage only one core is used (because the remaining packages directly or indirectly depend on ATLAS).

Well, as long as also the shared libraries are present, they're (usually) preferred over the static ones (i.e., unless one explicitly asks for linking against the latter), so copying these into $SAGE_LOCAL/lib/
IMHO shouldn't hurt. (The static libraries are btw. needed to compare different ATLAS installations; the only way to "keep" them is to reinstall the ATLAS spkg with ./sage f s ...
or to set SAGE_KEEP_BUILT_SPKGS

Note that previously installed static ATLAS libraries currently don't get removed. Don't know whether that may cause trouble (e.g. with upgrading); see above.

Its true that it doesn't hurt to have the static libraries as long as you don't use them. This is like saying that a knife doesn't hurt until you are stabbed with it. True, but why put a sharp blade under the couch pillow in hopes that nobody will sit on it?
It would be nice to have some system to compare different atlas versions and compile runs, but thats definitely for another ticket. Ideally the atlasconfig
python script could save the atlas libraries in a private directory, for example by setting a special environment variable while building atlas. And then have some way to tabulate the performance of different installs.

As I explained previously, thats not true. We have to change things to make them better. But we can't unlink the static linkage that has happened previously, so when you upgrade from an existing spkg you potentially keep the old code. And there is nothing a new atlas spkg can do about this. If you want to be sure that you don't have cruft statically linked you'll have to do a clean install. This is precisely why it was a bad idea to install static libraries previously.

We can use a preinstalled ATLAS library on the buildbots. Given that this is by far the slowest part of the compile cycle, I think thats reasonable. We even do this officially on OSX where we always use the systemprovided BLAS. But perhaps easier would be to update the Itanium archdef so that it doesn't have to tune. I just started a compile on iras, but don't expect the answer too soon ;)

You mean the (reproducible) segfaults on some AVX CPUs? These can be solved by reinstalling the ATLAS spkg (one or two times)  which doesn't take that long, as these CPUs are fast... ;)
No, seriously, as a temporary "solution", we could at least put the old ATLAS, BLAS and LAPACK spkgs into the experimental branch, such that (e.g.) Itanium users can still access them (to be installed manually with ./sage f ...
of course).
W.r.t. the "dead archictecture": It's IMHO always good to test on a broad range of platforms, as that might expose real bugs that just incidentally don't show up on the "mainstream" (Intel, AMD, meanwhile perhaps also ARM); if one day GCC does no longer support Itanium, the situation will be different.

Thats quite a speedup. I guess in your earlier test ATLAS failed to use the SAGE_ATLAS_ARCH=fast
build because of system load (first attempt), then tried SAGE_ATLAS_ARCH=base
which is the old Itanium (not Itanium 2), which then did a full search for timings. Something like that must have happened, the compile is not just 30x faster without background jobs running.
So I guess all problems are solved?

Technically if we want to use atlas on OS X a number of spkg including cvxopt needs to be updated.

On the first try, this built successfully for me on iras, lena, and hawk. (I've built it at least twice on iras and hawk, with no failures.) On the other hand, cicero (Linux x86) and flavius (Linux x86_64) both fail to build, with essentially the same error. Log file here. They also both took a long time (about 17 hours for cicero) trying to build the ATLAS spkg. I think we need some new different settings, because the build times for cicero, flavius (almost 19 hours), and iras (34.5 hours this time) are way too long.
comment:149 followup: ↓ 152 Changed 9 years ago by
Oh I see, cicero/flavius have only a single CPU core. Talking about a blast from the past! In that case ATLAS doesn't build threaded static libraries, so we can't build threaded shared libraries. They are also so old that ATLAS can't figure out whether CPU throttling is enabled, so the full timings are collected instead of immediately falling back to a predefined archdef. Instead of trying to catch this in the ATLAS spkg and potentially not running the tuning in cases where we ought to, I think we should just configure the buildbot to set SAGE_ATLAS_ARCH=base
on these ancient machines.
comment:150 Changed 9 years ago by
I thought one of the purposes of the buildbot was to test that Sage builds "out of the box" on a variety of platforms, so tuning environment variables for use with the buildbot machines doesn't seem like the right solution. But maybe I'm not thinking about the buildbot the right way.
Also, supporting "ancient" machines is important: if we want mathematicians in underdeveloped countries, for example, to be able to use Sage, they may not have access to anything better.

Well nobody stops you from tuning ATLAS for a day if you have an ancient computer. Its just annoying on the buildbot if you want to test something else than the ATLAS build.

well, 37 hours for a single package sounds like buildbot abuse. And I think that the default for slow machines with a single CPUs should be a basic Atlas install, with as little tuning as possible. There should be however be good documentation available on how to improve Atlas performance on a host, by rebuilding the spkg.
And I don't consider singlecore machines ancient.
One way or another, singlecore machines do not need many features of the new Atlas. Perhaps it's time to think about versioning possibilities: a metapackage Atlas that installs an appropriate for the architecture version?

comment:155 Changed 9 years ago by
Is there some sort of preliminary testing which could be done in spkginstall to try to catch machines which might take many hours to build ATLAS? For those machines, we could set the appropriate environment variable to skip as much tuning as possible, and then for quicker machines, we do more tuning. Something like
if [ z "$SAGE_ATLAS_ARCH" && machine_is_too_old ]; then SAGE_ATLAS_ARCH='skip tuning' # or whatever fi
(For 'machine_is_too_old', maybe just seeing if it only has one core would be enough.) Then the user can force tuning by setting SAGE_ATLAS_ARCH to something appropriate. I'm not sure this the the right variable, but anyway, I hope you understand the idea. Is this workable?
comment:156 Changed 9 years ago by
The old machines are slow because they are old and because there are no uptodate architectural defaults for ancient hardware. None of this can be fixed by a magic environment variable (except pointing SAGE_ATLAS_LIB
to the system atlas libraries). Basically, you can't skip tuning sparc just because you have i386 archdefs. There is a lot of assembler code that will be unhappy.
Also, I don't think there is an easy way to know that atlas would take a long time without actually building it. We could just install a reference blas on all nonstarteoftheart machines (say, less than 4 cores and 2GHz). But this will be a major rewrite of how Sage builds its BLAS libraries.

Oh I see, cicero/flavius have only a single CPU core. Talking about a blast from the past! In that case ATLAS doesn't build threaded static libraries, so we can't build threaded shared libraries.
Is that a bug in ATLAS or a bug in
spkginstall
? The version of ATLAS currently in Sage doesn't have this problem.
comment:160 Changed 9 years ago by
The current ATLAS does not work fine for some modern CPUs (search the mailinglist for reports), nor does it have AVX support. Realistically, if you want to have a fast BLAS then you need to track upstream pretty closely since a lot of linear algebra performance boils down to having a good (asm) implementation tuned to your particular hardware.
The build failures that I have seen logs for were just bugs in the Sage buildscript that I'm working on fixing.

The updated spkg fixes the issue with singlecore processors. Builds fine on cicero.

Builds on cicero and flavius. On mark (Solaris), I see a problem building scipy. Could this be related? Log here.

Yes totally ATLAS related. May you could also post ATLAS's log or at least the end bit of it where it builds lapack.

I've added archdefs for Itanium2, now build time is a lot faster:
vbraun@iras:~/opt/iras/sage5.3.beta0> SAGE_ATLAS_ARCH=fast ./sage f http://www.stp.dias.ie/~vbraun/Sage/spkg/atlas3.10.0.spkg [...] real 44m44.170s user 41m47.156s sys 2m42.456s
Though if you don't specify SAGE_ATLAS_ARCH
it will still run, by default, a full tuning. If that fails for any reason it will try SAGE_ATLAS_ARCH=fast
next.

I am not sure what happens at all. I am not convinced that the original lapack archive is getting relinked along with the C interface from ATLAS but that's not easy to establish from the log because of the size. I would need to spend some time looking at it carefully.

The OSX 10.4 issue is a cvxopt bug. Where is BLAS in the ancient vecLib and why didn't Apple call it libblas? In any case I don't have access to a museum Mac, so somebody else will have to figure that out.
Reporting for duty! Currently building MPIR, with with changes in this ticket (except the doctest/doc patch, which is no biggie).
Would this issue only come up if someone did set SAGE_ATLAS_ARCH=base
or at any rate set it? I though that using the system ATLAS was still the default on Mac after this ticket  was that a misunderstanding? I might find out before I leave work today... but if it doesn't break without resetting that variable, I don't think that is as bad, since hopefully no one using this old of a machine is depending on it for fast linear algebra.

That would be a start but most of the spkg using blas have specific rules for OS X and we would need to change them before they start using ATLAS instead of veclib. From the top of my head:
 iml (actually that would solve some problems)
 linbox
 numpy
 scipy
 cvxopt
 R?
I believe sage itself can cope with the change as is but it should be checked.
comment:169 Changed 9 years ago by
My point was not that we should switch to ATLAS, but rather that it might be possible to have a different ticket for making ATLAS work optionally on Mac this way, if Sage builds and tests fine with this new ATLAS in the case where Mac does not actually build it. I don't know if that's true, though, since jdemeyer's report could perhaps have been with that env var set.

Correct, PowerPC G4, which I think is slightly different. It's currently compiling fine, I'll let you know the results.
In other news, #13408 seems to be a dup of this ticket. I don't know if we support "rhel 5" systems currently, nor whether this particular spkg fixes that person's problem, though.

Good as far as it goes! Is this the record for longest ATLAS build ever?
Typing make

So all we have to do is build ATLAS on OSX 10.4, then we don't have to figure out how to drive the ancient accelerate framework. Dima, can you change cvxopt to link against atlas on 10.4?
comment:176 Changed 9 years ago by
I see, so that's why the problem is the same. Sounds like either we would do this, or fbissey's idea of a different configuration now.
I've touched cvxopt and am trying to build the rest of Sage now, so don't hold your breath yet that this was a permanent fix (in addition to roughly doubling the build time of Sage, not that this would matter on this platform).

The last two errors are really a misconfiguration/miscompilation of numpy. If you look at /Users/student/Desktop/sage5.3.rc0/local/lib/python2.7/sitepackages/numpy/linalg/lapack_lite.so with otool L (I think) you may see something. In fact the deeper problem seem to be that the dynamic lookup doesn't find libatlas.dylib. I am not sure if explicit linking would solve the problem. We should look at the numpy spkg and also atyour numpy log to see how lapack_lite.so was linked.

For R it looks like a similar problem. R uses lapack and compile its own subset if not present. It also looks for ATLAS specific bits. Did you run otool from the sage shell? In this case I don't think it matters but you should look at those library problem from a sage shell to get the right LD_LIBRARY_PATH settings.

comment:185 Changed 9 years ago by
OK that's weird. According to your log of building numpy, lapack_lite.so was compiled against veclib rather than atlas and this is in accord with your otool output. So the problem may steem from a relinking or hiding of the veclib library by atlas. It is probably finding the symbols in the ATLAS install first. The problem in turn seems to be that libatlas.2.dylib is missing a symbol or that it should be provided by an extra library not provided. otool L r on libatlas.2.dylib? (I hope the r does what I except: same thing as r in ldd in linux), actually on lapack_lite.so while you are at it.

It's not. I am not sure there is an otool equivalent for "ldd r". Another point: from the error you get I am expecting that if you start python from the sage shell and then "import numpy" if will fail with a similar error. Starting python with "v" may show us what libraries get loaded exactly when you import numpy.

comment:190 Changed 9 years ago by
Hi,
now that I reread the comments here again, I seem to faintly remember this problem circle from my adventure with lmonade (Gentoo Prefix derivative) on OS X 10.4 last year. See my travel account about this, points "22." and "26." and especially the rant following that in:
https://groups.google.com/d/msg/lmnddevel/1ZqHx1JBY2Q/syAOZYtZN4IJ
 If my memory is correct, the symbol "_ATL_DecAtomicCount" comes from/is resolved in libblas(.dylib), this could be checked independently from the underlying OS. Where is libblas.dylib (libblas.so under Linux) located, is it something like .../lib/blas/reference/?
 KarlDieter, I try to catch up with what you installed and tried, but till then could you please try
"sage R"
anyway in the meantime (from the shell prompt) and print the result, probably an error message from the OS X 10.4 lessthanoptimal dyld dynamic loader?
 If this really is what the problem is about, some symlinks might suffice, but I do not remember exactly how and for which libraries (both R and maxima were affected in a weird way, and Volker's compilerwrapper intervenes in the lmonade setting, too).
Best regards,
Georg
P.S.: Later last year, I ultimately managed somehow to get some 64bit Sage (lmonade flavour) working on the 32bit OS X 10.4, so in the course, I definitely had to successfully build and link/reference some new "selfmade" 64bit atlas/blas, since OS X 10.4 only ships with a 32bit "system copy" of atlas/blas, so this is definitely doable. But even Python itself is not officially supported as 64bit version on OS X 10.4, so quite some more hackery was needed. (This only might be interesting, if one day the Sage project wants to get rid of the dependency of certain Apple system library headers, which come only with "XCode", or more precisely the "command line tools", on newer OS X versions  currently these are a prerequisite for building Sage on OS X.)

Yeah I remember those bits vaguely now. But lmnd never used libvec unless you hacked something (I have an ebuild to allow that but noone else has seen it). The location you mention in (1) is specific to gentoo and correspond to netlib blas (otherwise called blas reference) current lmnd uses a different scheme. A lmnd user could pick openblas or gotoblas these days.
The link idea is interesting, having $SAGE_LOCAL/lib/libblas.dylib pointing to libvec could help.

With OS X 10.4 on my MacIntel?, I ran with sage5.3.rc1 into the same problem as earlier reported here (for Sage5.2 and Sage5.1, I can confirm the problem exists already for Sage5.1):
The fix is trivial (once one knows what the problem is), in module_list.py there is a "lpari" option missing for the cremona.mat module (for the other cremona.xxx modules, the "lpari" option is listed with a comment about "Cygiwn might need this"  obviously the dynamic linker/loader on OS X 10.4 MacIntel? is comparably dumb). Once I sorted out creating a corresponding ticket, uploaded the fix there, and answered to the thread above, I'll continue with the atlas story here.
comment:194 Changed 9 years ago by
Hi all, it is really puzzling, why with current Sage5.3 on OS X 10.4 PPC (yesterday released, it's up on the servers), the cvxopt1.1.5 spkg finds during its build the blas.dylib  but with the changes of this ticket here, cvxopt1.1.5 does not find it anymore (see comments #142 and #170 here).
Some facts:
 On OS X 10.4 PPC, under the directory "/usr/lib/", there are no "atlas.dylib", "blas.dylib", "cblas.dylib", "lapack.dylib" files or links (on OS X 10.4 Intel, these four entries *do* exist there, as links).
 On OS X 10.4 (both PPC and Intel), Sage historically does not build atlas nor blas (nor cblas) nor lapack, so there are not corresponding dylibs either under "$SAGE_ROOT/local/lib/".
 In $SAGE_ROOT/devel/sagemain/module_list.py, there is some magic for the configuration of the "BLAS" and "BLAS2" macros. Given the above fact(s), on OS X 10.4 PPC, I read these as resulting to use "gslblas" (!!) provided by Sage, on OS X 10.4 Intel, I read these as resulting to use the system "cblas" and "atlas".
 On OS X 10.4 Intel, these "system" atlas, blas, and cblas libraries actually all link to one and the same "blas.dylib" located under /System/Libraries/Frameworks/Accelerate?.framework/version/A/vecLIB.framwork/version/A/ (or some permutation thereof, I can't look up the exact path right now at the moment). These libraries are also located there under OS X 10.4 PPC, but there do not seem to be any links.
 The old cvxopt1.1.4(.p1) lists "gslblas" as library to be linked to, but actually, it is unclear at least to me, which kind of "blas" library really got used in the end on OS X 10.4  maybe on PPC some different one than on Intel.
Is it possible that currently, the build of cvxopt1.1.5 on OS X 10.4 PPC succeeds only during a "whole" build of Sagte5.3, the linker somehow caching the libraries it finds in the course of the build (especially "blas.dylib" somewhen before cvxopt is built)  and with the changes of this ticket, the build sequence changes somehow so suddenly, "blas.dylib" is not anymore in this cache (or whatever kind of mechansim with the same result)?

Before this ticket netlib's blas (blas spkg) would be build on OS X if I am not mistaken. So an unoptimized blas would be present to be picked in SAGE_LOCAL/lib. cblas would indeed be provided by gslblas if nothing else.

hmm, no, I think on OSX there is native blas/lapack (veclib) which was used (and still is used, given the right settings used to build Sage).

I agree with Francois, we probably never used the ancient accelerate (OSX 10.4) framework correctly. In fact, this ticket makes it pretty clear that we did not.

as far as CVXOPT is concerned, it does use MacOSX veclib (there was a OSX 10.7related ticket which dealt with the fact that veclib changed some undefined behaviour when 10.7 was released, and CVXOPT got hit by this issue).

It is not necessary to "start a fresh 5.3 or 5.4.beta0". Instead, one can go to some Sage OS X PPC download page, http://boxen.math.washington.edu/home/sagemath/sagemirror/osx/powerpc/index.html , download from there e.g. "sage5.3OSX32bit10.4PowerMacintosh?Darwin.dmg", and look inside  on any OS X system/version. The result is ... surprising, to say the least:
sagebuilder$ otool L lapack.so lapack.so: /Users/buildbot/build/sage/moufang1/moufang_binary/build/sage5.3/local/lib/libgfortran.3.dylib (compatibility version 4.0.0, current version 4.0.0) /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /Users/buildbot/build/sage/moufang1/moufang_binary/build/sage5.3/local/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.1.12)
The two occurences of "libgcc_s.1.dylib" are somewhat fishy, but apparently nothing new, and I'd vote for that topic being a complete different story, and not to be treated here any further. The library "libSystem.B.dylib" is the C runtime on OS X, AFAIK. But then only libfortran.dylib  and no trace whatsoever of any *las.dylib?!?!? For comparison, on OS X 10.4 Intel, for Sage5.3.rc1 the analoguous result is:
sagebuilder$ otool L lapack.so lapack.so: /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libLAPACK.dylib (compatibility version 1.0.0, current version 192.15.0) /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib (compatibility version 1.0.0, current version 192.15.0) /Users/Shared/sage/sage5.3.rc1/local/lib/libgfortran.3.dylib (compatibility version 4.0.0, current version 4.0.0) /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /Users/Shared/sage/sage5.3.rc1/local/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.3.11)
I would conclude that it is problematic, that the OS X 10.4 PPC linker/loader builds at all the current cvxopt1.1.5 spkg contained in Sage5.3, producing results with such incomplete dependency information. Looking closely on the command line, it is told to use "undefined dynamic_lookup" (which seems to save us at runtime later, however only by chance, I guess), so essentially it does what it should  but then, why does that linker/loader under some very comparable circumstances error out with "/usr/bin/ld: can't locate file for: lblas"???
Of the different alternatives to come to an end with this ticket here (which is about the new atlas3.10 spkg), I like the "link idea" (see the comment 191 from Francois), i.e. the atlas spkg, generally on OS X (!), doing no more and no less than creating links in $SAGE_LOCAL/lib/  the same as exist in /usr/lib/, at least on OS X 10.4 Intel. More precisely, three links pointing to the "framework" blas library:
libatlas.dylib > /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib libblas.dylib > /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib libcblas.dylib > /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib
and one more link for the "framework" lapack library (all link targets being absolute, not relative):
liblapack.dylib > /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libLAPACK.dylib
A quick check shows that at least on OS X Intel, the absolute path to these framework libraries is the same for OS X 10.4, 10.5, 10.6, and 10.7 (I can't check for OS X 10.8), and even on OS X 10.7.3, there still is only one version "A", which is the "Current" version of that framework.
This change, for all OS X variants, would be a bit intrusive. But to me, it seems to bring the OS X world a bit closer to the situation on the other OSes. I offer to test a respectively updated atlas spkg on the OS X systems/versions I have access to. (In the "patches" subdir, one also might wish to delete the "edit" duplicates of two files, those with a tilde at the end of their file name.)
Thoughts?
comment:206 Changed 9 years ago by
I can't pretend to understand exactly what all the linking is doing here  it seems very much a black box. But those two absolute paths certainly exist on my box, and seem like a good alternative to trying to get ATLAS to build from scratch on OS X for now. I will naturally also volunteer to test on anything I have access to.

Replying to dimpase:
as far as CVXOPT is concerned, it does use MacOSX veclib
Are you sure? I think OSX 10.4 is rather different from modern OSX accelerate. Post the output of
otool L
on OSX 10.4 PPC or it didn't happen ;)
On 10.5 PPC it is veclib all right...
$ otool L lapack.so lapack.so: /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libLAPACK.dylib (compatibility version 1.0.0, current version 218.0.0)

So you mean that after
if conf['Darwin?'] \ and not os.environ.has_key('SAGE_ATLAS_ARCH'): print 'Skipping build of ATLAS on intel OS X' sys.exit(0)
in the spkginstall (well, before the exit) we should add the linking described comment:205? That would seem easy enough, though I don't know what the syntax would be (not just ln
, I assume).

 Description modified (diff)
 Status changed from needs_work to needs_review
I don't think we should be symlinking system libraries into local/lib if we can avoid it. Really cvxopt is broken, it should be linking against the accelerate blas but doesn't. In particular, we should correctly set BLAS_LIB_DIR
in cvxopt on Darwin. The update spkg fixes this. I've also changed the atlas spkg back to not build by default on Darwin. Please test the combination of both spkgs on your OSX machines.
Note that you cannot just use
sage f atlas3.9.32.spkg
to update atlas only. Many other spkgs use blas/lapack and must be rebuilt. The easiest way is to do a separate Sage installation...The cvxopt spkg needs to be updated to link correctly with this atlas release, see #10509.
