Description (last modified by )
Port Sage so that it builds and passes its full test suite on the new IBM Power 7 architecture running SUSE Linux.
This is the only test failure with sage-5.12.beta1:

fbissey -- do you want an account on skynet, so you can help us with porting to SUSE on a nice new "IBM Power 750 Express server" that we have?

We are getting 13 power755 locally but they'll go live at the end of September - I am currently installing a power720 that is meant to be a deployment server. Got a BlueGene?/L and BlueGene?/P as well but that would be another exercise :)
The big pity as far as I am concerned is that there is no Gentoo-prefix for linux-ppc otherwise I could have been up and running faster.
We currently have some power5 575 some of which are running suse 9 and that's awful, the latest gcc I have been able to compile is 4.2.4.

I notice in the build logs that you have gcc-4.6.1 on that box. Is it a manual install of gcc?

Yes. Here is some info about the machine. If you want an account on it, send me an email and I can arrange it.

I have created a spkg with the latest maxima in case that would make a difference but unsurprisingly it doesn't.

So big trouble coming from mpfr or possibly mpir underneath. Once we isolate that most of these will disapear.

I was hoping the mpir upgrade would deal with some of these. I'd like to try a vanilla compiler from SLES (gfortran is on a separate SDK DVD I discovered).

Replying to jhpalmieri:
With the new mpir spkg from #11964, Sage builds for me on silius, using gcc 4.6.2. I get a lot of test failures, though: I think that many of these are as reported before. See the log for full details.

FWIW, I previously managed to reduce the doctest errors to 7 files IIRC; from sage-release (Sage 4.7.2.alpha3 thread):

P.S.: The following tests even timeout when run individually (with the default timeout of half an hour on a quite fast box) in my current build: sage -t -long -force_lib sage/rings/real_mpfi.pyx # Time out sage -t -long -force_lib sage/rings/polynomial/polynomial_element.pyx # Time out sage -t -long -force_lib sage/rings/number_field/number_field_element.pyx # Time out sage -t -long -force_lib sage/sage/rings/number_field/number_field.py # Time out Interestingly also sandpile takes a long time, although this is SUSE Linux Enterprise Server 11 SP1 (ppc64), Kernel version 2.6.32.43-0.4-ppc64 and not Ubuntu. The other failing doctests are in: sage/misc/functional.py # 1 doctests failed (failing MPFR assertion) sage/interfaces/qepcad.py # 2 doctests failed (two funny errors) sage/plot/plot3d/list_plot3d.py # 2 doctests failed (two times "ValueError: negative dimensions are not allowed" in list_plot3d()) Note that there are further doctest errors in the files which timeout, i.e., before tests start to hang. -leif
I unfortunately cannot tell (at least at the moment) how I exactly built that version since I had trouble with various things like GCC 4.4.6 not recognizing -mvsx
(which ATLAS uses without first trying whether the command line option is supported) and the PolyBoRi spkg which didn't propagate LIBRARY_PATH
etc.

I cannot really post many details right now but the errors are similar to before. Problems with mpfr and scipy are the main culprits. Some details on the box used:

So we are expecting to catch some failure here in the first place and it doesn't go according to plan.

I am doing a complete test run with the new mpfi/mpfr combo but so far the results don't look any different. I looked a little bit more into the test that timed out (devel/sage/sage/rings/real_mpfi.pyx) with verbose and it stops dead there:
Trying: RIF(Integer(5)).gamma()###line 4133:_sage_ >>> RIF(5).gamma() Expecting: 24 ok Trying: a = RIF(Integer(3),Integer(4)).gamma(); a###line 4135:_sage_ >>> a = RIF(3,4).gamma(); a Expecting: 1.?e1
I'll look at the other killed test (libecm.pyx) a bit later.

Replying to zimmerma:

I did build both release candidates on Silius (Skynet); all [run] tests passed (although I don't recall with which GCC version; I guess I used my own build of 4.4.6).
I now see at least rc2 passed all tests with 4.3.4 and 4.6.1, too.
Same for MPFI 1.5.0?
Nope.

please could you check again with the 3.1.0 release? Alternatively if I have access to this machine (Silius?) I can try to investigate. William, is it possible?

IIRC there was no difference to the rc2 (except for version strings and the like), but I can probably retry a build tomorrow.
Alternatively if I have access to this machine (Silius?) I can try to investigate.
If you have a skynet account, you can log into silius from eno; otherwise you can ask Mariah Lenox for an account.

Please could you try with MPIR 2.1.3, which is as far as I know the version currently used by
Sage?

Well, that's the version GCC was built with, which doesn't matter here.
But I could rebuild and test MPFR 3.1.0 with (e.g.) MPIR 2.1.4 later.

Ok, I now also built MPIR 2.1.4 (changes w.r.t. 2.1.3 don't matter) and MPFR 3.1.0 with that version on silius; once without specifying any CFLAGS
(such that MPIR used -m64 -O3
, without any -march=
/-mcpu=
/-mtune=
), once with CFLAGS="-mcpu=power7 -mtune=power7 -m64 -g -O3
(but in both cases only with GCC 4.6.2).
All test suites passed, as expected.

Not sure how I ended with a crash in real_mpfi.pyx, there is a time out. But I don't see a crash anymore after a rebuild from scratch including mpfi-1.5.0. The time out may be caused by some other components.

if I modify the function mpfi_interv_z
of MPFI as follows:
int mpfi_interv_z(mpfi_ptr a,mpz_srcptr b,mpz_srcptr c) { int inexact_left, inexact_right, inexact=0; mpz_dump (b); mpz_dump (c); if ( mpz_cmp(b,c) <= 0 ) { inexact_left = mpfr_set_z(&(a->left), b, MPFI_RNDD); mpfr_dump (&(a->left)); inexact_right = mpfr_set_z(&(a->right), c, MPFI_RNDU); mpfr_dump (&(a->right)); } ...
then I get:
sage: RIF(1,2) 000000000000000001 000000000000000002 0.00000000000000000000000000000000000000000000000000000E65 0.00000000000000000000000000000000000000000000000000001E65 get_str.c:149: MPFR assertion failed: size_s1 >= m ...
thus clearly something is corrupted with GMP and MPFR, since we should get:
1 2 0.10000000000000000000000000000000000000000000000000000E1 0.10000000000000000000000000000000000000000000000000000E2
Note: I cannot reproduce the problem outside from Sage, thus it is probably due to the way GMP (i.e., MPIR) and/or MPFR are compiled within Sage.

Same thing with upper. But your remark about it working outside of sage makes me want to hack sage "provided atlas" style and see what happens.

comment:50 Changed 7 years ago by
FWIW, I've also built Sage 5.0.beta8 on silius (skynet), where GCC 4.6.3 meanwhile is the default compiler (although one still has to source /local/bin/skynet_bash_profile
, since otherwise a few packages, two IIRC, fail to build because of wrong libraries / not sufficiently set LD_LIBRARY_PATH
).
I've built once with MPIR 2.1.3 and once with MPIR 2.4.0[.p1], which doesn't seem to make a difference regarding the results of ptestlong
.
According to Bill, MPIR doesn't make (much) use of assertions; they mainly rely on their test suites (same for FLINT).
comment:51 Changed 7 years ago by
P.S.: I've of course built MPIR 2.4.0 (successfully) with SAGE_CHECK=yes
; the GCC on silius is itself built with MPIR 2.5.0 and MPFR 3.1.0.
I use -mcpu=power7 -mtune=power7 -O3 -g [-fno-strict-aliasing]
; with earlier Sage versions, I did build ECL with -mcpu=power4 ...
, which (besides other variations) led to less errors (doctest errors in only 8 files IIRC), but I currently can't give a comparison or more details.

All mpir/mpfr/mpfi tests pass (expect tget_set_d64 in mpfr which is skipped). One strange thing in mpfr
[tversion] MPIR: header 2.4.0, library 2.4.0 [tversion] MPFR tuning parameters from src/powerpc32/mparam.h
this is a powerpc64 machine (and I am sure mpir is configured 64bits), does it matter?
comment:55 Changed 7 years ago by
It doesn't seem to matter but I am not sure the configuration works as it should in mpfr, if both ARCH_PPC and PPC64 are present PPC64 is just ignored.
comment:56 Changed 7 years ago by
Francois,
I don't think it matters, since the mparam.h
file only contains tuning parameters,
however I will fix that in the development version. Thank you for pointing out this.

I've uploaded two config.log

- MPFR 3.1.0.p0 configured with MPIR 2.4.0 (p1 from #11616, otherwise Sage 5.0.beta9)
They don't differ except for the name of a temporary file.

Leif,
thank you. I did compare your config.log of MPFR 3.1.0.p0 configured with MPIR 2.4.0 with the one for a vanilla MPFR-3.1.0 configured with GMP 5.0.4:
(1) it seems your config.log does not extract CC and CFLAGS from gmp.h
(2) mine uses gcc -std=gnu99 instead of gcc alone
(3) your config.log uses -mcpu=power7 -mtune=power7 instead of -m64
(4) the linker used is ld in your case and /usr/local/binutils-2.21.1/ppc64-Linux-power7-suse-gcc-4.6.1/bin/ld
for a vanilla MPFR
I'd like to reproduce exactly your build with a vanilla MPFR but I cannot access some of your files:

It does, but MPIR takes (also) the flags I specified and hence writes these to gmp.h
:
leif@silius:~/.../sage-5.0.beta9-gcc-4.6.3> egrep "__(GMP|MPIR)_(CC|CFLAGS)" local/include/gmp.h #define __GMP_CC __MPIR_CC #define __GMP_CFLAGS __MPIR_CFLAGS #define __MPIR_CC "gcc -std=gnu99" #define __MPIR_CFLAGS " -g -O3 -mcpu=power7 -mtune=power7 -O3 -g -fno-strict-aliasing "
(This is the gmp.h
created by MPIR 2.4.0.p1. I know the one from MPIR 2.1.3 does look different: First of all, __GMP_CC
and __GMP_CFLAGS
are defined to strings as well, instead of referring to their respective MPIR macros, and -- which is a known bug -- __GMP_CC
doesn't contain -std=gnu99
, although __MPIR_CC
does.)
(2) mine uses gcc -std=gnu99 instead of gcc alone
This shouldn't matter; I could retry building MPIR and MPFR with CC="gcc -std=gnu99"
though.
(3) your config.log uses -mcpu=power7 -mtune=power7 instead of -m64
See above.

I'd like to reproduce exactly your build with a vanilla MPFR but I cannot access some of your files.
I've copied the headers and libs into /tmp/leif/sage-5.0beta9/MPIR-{2.1.3,2.4.0}/local/{include,lib}/
, so you should be able to configure MPFR with --with-gmp=/tmp/leif/sage-5.0beta9/MPIR-2.1.3/local/
etc.
[Sorry for the delay, had some network trouble.]

with MPFR configured with --enable-assert
within sage-5.0.beta9, I can simplify the
problem to:
sage: RIF(1,1) get_exp.c:29: MPFR assertion failed: ((x)->_mpfr_d)[(((((x))->_mpfr_prec)-1)/(64 - 0)+1)-1] & ((~(mp_limb_t)0) ^ ((~(mp_limb_t)0) >> 1))
This means that we compute the exponent of a number which is either NaN, infinite or zero. I will continue to investigate.

comment:63 follow-up: ↓ 64 Changed 7 years ago by
I have spent several hours on this and my conclusion is that the culprit is Sage (i.e. Cython).
In real_mpfi.pyx
one can read:
elif PY_TYPE_CHECK(a, Rational) and PY_TYPE_CHECK(b, Rational): rat = a rat1 = b # todo: The <object> coerce is evidently to get around a weird bug in SageX (?) mpfi_interv_q(self.value, <object>rat.value, <object>rat1.value)
and the same coerce is done in the integer case.
I am 99% sure that we hit that weird bug. Indeed with RIF(1,1)
the integers (mpz_t) which are
passed to mpfi_interv_z
are malformed, with SIZ=2
instead of SIZ=1
.
However I have no idea how to solve that weird bug, or how to find another workaround. Can we know who did write this comment?
It might be that the issue is related to the fact that the Power7 is big endian. Was Sage tested on other 64-bit big endian platforms?

Well, [SunOS/Solaris] SPARC (V9), but the 64-bit port (including x86_64) is still incomplete AFAIK. (There's some wiki page on it, and a couple of meta-tickets; or ask Dave Kirkby, who did most if not all of it on his own.)

Paul
comment:67 Changed 7 years ago by
I've sent a private mail to William. The bug seems clearly in Cython. In real_mpfi.c
I see:
__pyx_t_3 = ((PyObject *)__pyx_v_integ->value); __Pyx_INCREF(__pyx_t_3); __pyx_t_8 = ((PyObject *)__pyx_v_integ1->value); __Pyx_INCREF(__pyx_t_8); mpfi_interv_z(((struct __pyx_obj_4sage_5rings_9real_mpfi_RealIntervalFiel\ dElement *)__pyx_v_self)->value, __pyx_t_3, __pyx_t_8);
thus __pyx_t_3
is of the wrong type: it should be of type Integer and not of type Python object
(compare to the call to mpfi_set_z
in the same file).
Paul
comment:68 Changed 7 years ago by
I believe I understand what happens. The fact that __pyx_t_3
has the wrong type is not a problem,
since it is a pointer, like what mpz_t
expects as 2nd (and 3rd) argument of mpfi_interv_z
.
However my guess is that the __Pyx_INCREF(__pyx_t_3)
call is intended to increase a reference counter stored somewhere in the PyObject
struct. Since __pyx_v_integ->value
is not a Python object but a mpz_t
, this call makes a side effect on the mpz_t
structure, which has the
effect to increase its "size" from 1 to 2, which explains why the mpz_t
object seen by
mpfi_interv_z
is corrupted.
What is annoying is that this corruption also happens on other configurations (in particular
little endian). For some reason it gets unnoticed, maybe because the corrupted field is not the size
(maybe the allocated size). However one might be able to reproduce the problem also by changing the
order of the fields in the mpz_t
structure in gmp.h
. Putting _mp_size
first seems to
break Sage on 64-bit Intel processors.

./sage -b

Of course first make a copy of it, but I've patched C and C++ files generated by Cython a couple of times without problems.

thank you Leif. This confirms my guess: if I comment the two __Pyx_INCREF
before
the call to mpfi_interv_z

runs ok.
The problem is thus isolated, we now need somebody fluent in Cython to solve it or find another (platform independent) workaround.

The pyx just contains a type definition, and passes a null pointer to ecm_factor()
instead of some structure. Segfaults also happen outside of Sage; see below.
Is it possible to link libecm dynamically to Sage?
Of course, you just have to build a shared library (ECM_EXTRA_OPTS="--enable-shared"
); see below.
This is IMHO an upstream (or probably compiler/assembler etc.) bug.
Note that GMP-ECM's test suite segfaults in its first test when configured with --enable-shared
(and asm-redc enabled, which is the default). Same for a trivial stand-alone program just resembling Sage's doctest.
The segfaults vanish in both cases if I in addition pass --disable-asm-redc
. So Sage just exposes the problem, it doesn't cause it.
[FWIW, Sage's ecmfactor()
apparently works for even numbers, as well as interestingly 1025, while all other odd numbers between 950 and 1050 cause a segfault.]

The assembly code cannot work with dynamic linking, as all of its functions lack function descriptors.
I'll try to fix that tomorrow, although presumably not [yet] by an upstream-ready patch, as the .asm
(m4
) files are itself generated by m4

I've attached a patch to the three .asm
/ .m4
files all PPC64 assembly files are generated from. (FWIW, also applies clean to GMP-ECM 6.4.2.)
While the original files seem partially over-autoconf'd to me (e.g. TEXT
, defined in config.m4
after configure
), I've currently "hardcoded" the ELF function descriptors, i.e., haven't used new macros for them at all. Even if GMP-ECM currently only supports systems using ELF on PPC64 (I think; Darwin PPC is 32-bit, and asm-redc
is disabled on it, although it IMHO wouldn't have to be), one could at least write some m4
macros for [PowerPC] ELF![64] for convenience and put them into (e.g.) powerpc64/elf.m4
, then probably only "enable" them if configure
determines it's an ELF system. (I didn't want to mess with the autoconf
files anyway.)
One could also add some debugging info to the functions, i.e. traceback tables.
I haven't changed the broken indentation of redc.asm
, to keep the patch small and readable.
A preliminary GMP-ECM 6.3.p8 spkg (applying my patches) is here. Note that it is based on the p7 from #12830, which still needs review.
Patches
- ...
- mulredc.m4.patch, mulredc_1_2.m4.patch:
Add function descriptors to PPC64 assembler code to support dynamic linking.
(Even with a static
libecm.a
, Sage segfaulted with--enable-asm-redc
on Linux PPC64, because the [static] GMP-ECM library gets linked into a shared library, namely the Python extension module "libecm".) We patch the twom4
files the twenty.asm
files (insrc/powerpc64/
) are generated from; the latter are again macroprocessor files from which the (only temporary) real assembly files (.s
) are created during build. - redc.asm.patch:
Also add a function descriptor here, although apparently this code isn't
used by Sage, nor GMP-ECM's test suite, at least not currently (as of
GMP-ECM 6.3 / ecm-6.3.p8). (The function it provides is
ecm_redc3()
.)
ecm-6.3.p8 (Leif Leonhardy, April 24th 2012)
- #12830: Add patches to
src/powerpc64/{mulredc,mulredc_1_2}.m4
to support dynamic linking, otherwise the Python extension module "libecm" segfaults with--enable-asm-redc
on [Linux] PPC64, regardless of whether we build a shared and/or static GMP-ECM library. For consistency, also patchsrc/powerpc64/redc.asm
in the same way, al- though it doesn't seem that this code was currently used. (See also the Linux PPC64 meta-ticket #11705.)
I've only tested it on Silius, with --enable-shared
and --disable-shared
(--enable-asm-redc
is the default), with Sage 5.0.beta9 (plus some replacement spkgs and #12829) and GCC 4.6.3, FWIW.
Perhaps François could test the attached patch with vanilla GMP-ECM on AIX.

Reading configure.in

did someone test sage-5.0.rc1 on silius, to see which doctests still fail?

I did a test build and run of 5.1beta5 yesterday, with gcc-4.6.3 shipped with sage. There doctests failures in 4 files at this stage:
The following tests failed: sage -t -long -force_lib devel/sage/sage/functions/special.py # 2 doctests failed sage -t -long -force_lib devel/sage/sage/numerical/optimize.py # 6 doctests failed sage -t -long -force_lib devel/sage/sage/libs/libecm.pyx # 7 doctests failed sage -t -long -force_lib devel/sage/sage/plot/plot3d/list_plot3d.py # 4 doctests failed
Which I guess is fairly good and down from before the 5.0 release. I guess I should test an updated GMP-ECM next.

Are you sure, because I still get the 5 failures mentioned in the ticket description on Skynet silius.

That's very curious. I didn't have it in my doctest run. I must have done it wrong. The cvxopt does indeed still fail.
comment:115 Changed 7 years ago by
Sage's cvxopt spkg sucks. It's way overlinked everywhere. It probably won't help much with the tests but I will do experiments to bring it 1.1.5 and clean that mess.
comment:116 Changed 7 years ago by
Looking at special.py tests
sage: elliptic_kc(0.5) 1.8540746773 sage: elliptic_f(RR(pi/2), 0.5) elliptic_f(1.57079632679490, 0.500000000000000) sage: elliptic_f(1.57079632679490, 0.500000000000000) 1.8540746773
So in effect elliptic_f is not evaluated straight away on power7.
comment:117 Changed 7 years ago by
Just a note, it may not be power7 specific. I am building a debug version of sage with SAGE_DEBUG=yes and polybori-0.8.1.p0 compilation broke. So far that's the only thing that failed to build with SAGE_DEBUG.
comment:118 Changed 6 years ago by
Well, that was a long time to do anything. I have just build 5.7.beta3 + numpy-1.7. Apart from the expected stuff from numpy we have the same doctest files failing. But the number has gone down for two of them:
sage -t -long devel/sage-main/sage/libs/libecm.pyx # 7 doctests failed [was 10] sage -t -long devel/sage-main/sage/numerical/optimize.py # 2 doctests failed [was 6]
Now that we have a killer debugging system in place things may get interesting.

It has been down for a while, that's all I know.
I could possibly donate expertise to bring it back up depending on whether it can be dealt with remotely or not. But I would need more details on the way it is administered, I doubt there is an HMC or an xcat server for just one node.

Hi Paul,
Haven't tried yet and I certainly can provide detailed output and backtraces. I have just started a 5.7beta4 with SAGE_DEBUG. On beta3 we have this kind of failures currently:

AH reading spkg-install it doesn't imply testing of all spkg this one has a quick test suite that always run. And it didn't fail in beta3 without debug and now fails in beta4 with debug.

OK done. I am trying to figure out cvxopt problems again. I will split up the ecm issue since we have a fix. Is the fix included in newer ecm? sage is a bit behind it could be an opportunity to upgrade. I know that 6.4.2 compiles fine under linux and works with sage without changes - doesn't compile in my gentoo prefix on my imac core2 duo but I suspect the problem is the compiler.

We have a method that completely fail to converge. I had done some exploration in #12832 when I thought it was a problem in scipy and I will probably continue to track that one over there after a good editing of the issue description.

Francois, please could you try the new release candidate of GMP-ECM at http://www.loria.fr/~kruppaal/ecm-6.4.4-rc2.tar.gz? It includes the patch of this ticket.

I've tried to build Sage on another Power 7 running debian. This is a vanilla Sage 5.7 + ATLAS from #10508, I did not try to include any patch from here yet. No problem to build it. The log of "make ptestlong" is at http://boxen.math.washington.edu/home/jpflori/ptestlong-gcc110-power7-debian.log Ive not had a deep look but the failures look similar to what has been reported here.

You have more failures. In the tutorial translations curiously your gap install totally crashed. And the rings/arith.py failure is totally weird. I'll try to move to 5.8.beta to see if I can reproduce some of these. You don't have the failure in functions/special.py. I suspect gcc is involved. What gcc do you use?

Please note I used 5.7 (plus new ATLAS).

Its
gcc version 4.7.2 20121109 (Red Hat 4.7.2-8) (GCC)
And as you can see its not Debian but Fedora...

OK, I think getting a new gcc on board may help. Of course you are using a gcc provided by red hat for ppc so there may be specific fixes in there. We know that some version of gcc were leading to breakage in ecl earlier on.
The next thing is that in some circumstances your GAP is breaking. If it was just plain broken there would be more test failures.

You mean more recent that 4.7.2? That will be quite bleeding edge won't it?

Indeed, I can launch the built gap and compute 1+1

I retested arith.py individually and it just worked...
comment:145 Changed 6 years ago by
Same for all rst files except cvxopt.rst which still fails (prec problem which was already reported here on the Suse install).
optimize.py and libecm.py are still failing as expected.
special.py still does not fail.
comment:146 Changed 6 years ago by
I was going to ask you to re-test. Not reproducible, it may be a small problem with parrallel testing, possibly concurrent GAP sessions. Not sure for arith.py.
As for compiler I meant that I used 4.7.1 for my own build. You are using a recent so you could also have small bug fix in kernel or glibc that helps (on a not mainstream platform).
comment:147 Changed 6 years ago by
I tried 5.8.beta2 with gcc 4.7.2 and it is worse (no patch applied):
The following tests failed: sage -t -long -force_lib devel/sage-main/sage/groups/matrix_gps/matrix_group.py # Time out sage -t -long -force_lib devel/sage-main/sage/combinat/sf/k_dual.py # Time out sage -t -long -force_lib devel/sage-main/doc/en/numerical_sage/cvxopt.rst # 1 doctests failed sage -t -long -force_lib devel/sage-main/sage/libs/libecm.pyx # 7 doctests failed sage -t -long -force_lib devel/sage-main/sage/functions/special.py # 2 doctests failed sage -t -long -force_lib devel/sage-main/sage/numerical/optimize.py # 2 doctests failed
So I still get the special.py failure which means something esle fixed it for you (I suspect glibc/kernel). I also have two time out. I am doing a gcc 4.7.1 to see if they are compiler dependent.

I am planing to test the new e cm spkg ASAP but I am a bit buried into reporting at work. Upstream cvxopt provided me with a cvxopt 1.1.6beta to try to solve the issue. It is on my todo list as well. Finally from Jean-Pierre's test it look like the ecl/maxima problem is one last gcc issue on ppc. I heve to try patch from fedora to gcc to confirm this.

I'm using the skynet machine silius
, which is back online.
comment:161 follow-up: ↓ 164 Changed 6 years ago by
Is silius still running SLES11? If so which SP? It seems that Jean-Pierre had more luck with that last bug using fedora 18. So I am suspecting something in the toolchain - but it could be ld, glibc or even kernel stuff rather than just gcc.
comment:162 Changed 6 years ago by
According to /etc/issue
, it is SUSE Linux Enterprise Server 11 SP1
.

Finally from Jean-Pierre's test it look like the ecl/maxima problem is one last gcc issue on ppc. I heve to try patch from fedora to gcc to confirm this.
I suppose you are refering to the special.py
failure? Why do you think it is a GCC issue?

If there is another machine on which special.py
works, then we can really investigate. jpflori: can you retest with the latest Sage beta? If everything works there, is there any chance I could get access to that machine?
comment:165 Changed 6 years ago by
Yes, this is the last failure we observe. It is related to maxima/ecl. I have no proof of it being caused by GCC. Just a hunch based on the fact that the first hurdle we had in the port was that maxima wouldn't build because the version of GCC used miscompiled ecl. Furthermore Jean-Pierre Flori reports that he doesn't observe the failure on fedora 18 whose toolchain is based on gcc-4.8.0.
My gut feeling is that an element of the toolchain is responsible.

I've just launched a build of 5.10.beta5 (not official, but at least there is the latest ATLAS there). And yes I guess you can access it, it's gcc110 on GCC Compile Farm.

Did you try to build ECL with -mcpu=power4
(as opposed to power7
, say)? (Maxima will pick up ECL's flags, too.)
Although both Maxima and ECL have meanwhile been upgraded at least once, I previously did have more luck with that. (I'm not entirely sure, but IIRC GCC 4.4.6 did successfully build ECL and Maxima even without that, and with much fewer doctest failures, and especially ;-) not in special.py
. Same with later GCC versions and -mcpu=power4
.)
Note that distros' GCCs generally use more generic target CPU types than a GCC you build natively.

Ask for an account foolowing the instructions there: http://gcc.gnu.org/wiki/CompileFarm saying you're working on (the GPL licensed) Sage. The guy in charge is quite reactive.

5.12.beta1 on SLES11SP1 with gcc 4.8.1 and binutils 2.22. Still problems in functions/special.py - there is one more failure there. I also got two timeout but I haven't checked yet increasing the time limit.
comment:176 Changed 6 years ago by
On gcc110, no problems at all with current git develop (6.1.beta2) :)
comment:177 Changed 6 years ago by
I spoke too fast, it seems it was with 6.0. I have problems with the ncurses ada bindings with 6.1 betas.
comment:178 Changed 6 years ago by
I'm getting noisy, in fact it was the converse, the problem was with 6.0, not 6.1 betas.
comment:179 Changed 6 years ago by
I still got the failures in special.py on sles11sp1. I have another amusing one that I can produce at will:

For a little bit of background, I used a compute node to build/run the test suite. Which means that the testing was submitted as a batch job using loadleveler (a batch queue manager from IBM). loadleveler starts jobs without a tty which cause these errors. testing from the command line proper the failures just disappear.

Did someone try to build pillow (included in latest betas)? It seems to fail on gcc110 with ld yielding "escamotage incompatible" which is very nice french but not that easy to decipher without context. Anyway it seems there is some 32/64 bit issue here, and the corresponding english error message would be "skipping incompatible library" which is more talkative.
comment:181 Changed 5 years ago by
Usually because you try to link a 64 bit object with a 32bit library. Yes it probably find the wrong version of one of the libraries (ziplib, png, jpeg) the setup script is not very smart but I thought we had ourselves covered. Would you by any chance have some of the aforementioned libraries installed in 32bit but not 64?
comment:182 Changed 5 years ago by
I'll have a look. Sorry for the rough report, I basically just wanted to know if that also happened to someone else, so I did not investigate it yet.
comment:183 Changed 5 years ago by
I have 6.1 beta3 built here with pillow and without a hitch. I honestly don't think it is a power7 issue per see. setup.py is not very smart at detecting stuff so you have to consider all corners. I have been in the latest gentoo bug concerning building pillow as well as the pillow ticket here. This stuff is fragile.
comment:184 Changed 5 years ago by
Ok, the problem is simply with liblcms install on gcc110. For some reason there is no liblcms.so in /usr/lib64 (although different versions of 64-bit liblcms.so.* are available there), but one in /usr/lib pointing to a 32 bit version.
comment:185 Changed 5 years ago by
That probably mean that there is a 64bit dev rpm not installed. But that's what I suspected.

So I finally pointed the finger to glibc/kernel headers. To build sage on SLES11SP1 and probably some other "enterprise distro" that are far behind in their toolchain stack on power7 I recommend IBM advance toolchain 7.0.3 and later. http://ibm.co/AdvanceToolchain It include its own glibc and that's the killer feature to get through the final issue I think. It is possible that gcc also includes a few IBM patches.
