the current graphite branch segfaults & ICEs on several files from CP2K.
Compiling with '-O2 -ffast-math -funroll-loops -ftree-vectorize -march=native
-fgraphite -fgraphite-identity'

To reproduce get 

http://www.pci.uzh.ch/vandevondele/tmp/CP2K_2008_12_03.tgz

untar and type make

at least on the following files:

mltfftsg.F
mltfftsg_tools.F
harris_force_types.F
ai_moments.F
cp_units.F
ps_wavelet_util.F
cp_fm_basic_linalg.F
ps_wavelet_kernel.F
ai_angmom.F
distribution_optimize.F
qs_util.F
atom_fit.F
atom_operators.F
dynamical_coeff_types.F
pw_spline_utils.F
pw_poisson_types.F
xc_derivative_set_types.F
cp_ddapc_methods.F
qs_all_potential.F
qs_operators_ao.F

I have ICEs.

The first one is:
ai_moments.F: In function ‘cossin’:
ai_moments.F:44: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
make: *** [ai_moments.o] Error

The same files compile fine with '-O0 -fgraphite -fgraphite-identity' so I
guess it is related to applying graphite to optimized code (or the other way
around).

Tobias, 

you might be interested to check if your recent patch also fixed these bugs.
Otherwise I should be able to give it a round of testing before the weekend.

Thanks for these test cases.

My commit fixed at least one failure, but there are more.

To help us it would be great to get a little bit structure in the failures.
Just get for every failing test a backtrace and create for every different bug
a new bugreport.

A little bit like Bub37894 for polyhedron.

It would be awesome, if you also could add one reduced test case and one
backtrace to every bugreport.

with current graphite, i see 4 files failing with -fgraphite
-fgraphite-identity:

lebedev.F, colvar_types.F, qs_linres_nmr_shift.F, constraint_clv.F

I'm assuming that these are all incarnations of PR38461, but can look into more
detail if that's considered useful.

all fixed with current graphite branch. The full CP2K sources now compile with
-fgraphite -fgraphite-identity

I'm adding -floop-block -floop-strip-mine -floop-interchange to the list of
options and will close this PR as fixed if this goes fine.

Unfortunately, '-fgraphite -fgraphite-identity -floop-block -floop-strip-mine
-floop-interchang' goes generate an executable, but it is miscompiled and
segfaults.

It can be reproduced with the testcase in the initial comment, adjusting the
FCFLAGS in the makefile and 

make clean
make
make test

After Sebastian Pop's fix for PR38492 the test run goes a bit further but
segfaults again, now with a different trace:

(obviously absent if compiled without graphite).

build_neighbor_lists (fist_neighbor_lists.F) is pretty loopy code, so well.. 
even though the routine is not so long, it wont be easy to reduce it, as it
depends on quite a few types defined elsewhere (it would be nice if the fortran
frontend could generate 'preprocessed' source without module dependencies,
they're similar to C header files.).

The testcase in PR38492 indeed works if I use:

gfortran -O2 -ffast-math -funroll-loops -ftree-vectorize -march=native
-fgraphite -fgraphite-identity -cpp -D__FFTSG -fno-strict-overflow test.f90

(i.e. no need for -fno-strict-aliasing) I'll give it a try on the full code.

Thanks for the update.  I suspect that this is due to -floop-block.
There are two more bugs 38559 and 38499 that we're looking at for
fixing -floop-block.

yes, I was able to derive a small testcase for this problem (PR38760), and it
requires floop-block to trigger.

Hi,

With the latest trunk CP2K compiles with -O2 -floop-block.  I tried to
run CP2K with -floop-block but I got an error due to the libblas
installation on my system (missing symbols in libblas that uses the
libgfortran of gcc 4.2 of my system).  I would have to install libblas
manually with current gcc trunk.  Could you try to run again the make
test and report the status of CP2K?

Thanks,
Sebastian

Hi Sebastian,

the testcase provide runs fine (AFAICT) with current trunk. I'll run the full
CP2K testsuite to test somewhat better.

Thanks,

Joost

Thanks for testing.  Can you close the bug after the CP2K testsuite passes?

Thanks,
Sebastian

unfortunately, there is still one runtime segfault, I have no reduced testcase
so far, but this is the backtrace:

Program received signal SIGSEGV, Segmentation fault.
__mc_moves_MOD_change_bond_length () at
/scratch/vondele/clean/cp2k/src/../src/mc_moves.F:1434

Created an attachment (id=17062)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=17062&action=view)
additional cp2k input 

With this CP2K testcase the segfault can be reproduced. After building cp2k,
just run:
cp2k.sopt canonical.inp
the segfault is almost immediate.

I had a further look into this. It is sufficient to compile the file mc_moves.F
without graphite to avoid the segfault, while compiling it with '-fgraphite
-fgraphite-identity' is  enough to get the segfault. I would therefore guess
this is unrelated to blocking and local to the file mc_moves.F. I'll see if I
can narrow down the problem to the single subroutine (change_bond_length) which
I suspect is the issue. [all of this with trunk 143207]

yes, just looking at change_bond_length should be enough.

I'm looking at the code generated for this function.
Thanks for the detailed analysis.

Re: [Bug middle-end/38431] [graphite] several ICEs with CP2K (summary)

Hi,

I compiled BLAS and LAPACK with the gfortran compiler of the graphite
branch such that I could test the CP2K benchmark.  On my laptop, that
is an amd64-linux, "make test" passes with the gfortran compiler from
the graphite branch.  However I'm not able to run the test that you
reported failing:

./cp2k.sopt canonical.inp
 CP2K: The specified file canonical.inp can not be opened, it does not exist.
STOP 1

Could you tell me where I can find the canonical.inp file, or how to
reproduce the fail?

Thanks,
Sebastian

you'll have to untar the additional_test.tgz which is attached here to the PR:

[-- Attachment #1: Type: text/plain, Size: 816 bytes --]

Thanks for the clarification, I managed to reproduce the fail.  The
problem comes from the fact that we do not generate code for a scalar
reduction that is not detected as a scalar reduction with the variable
connection$dim$1$lbound.

In the attached output from debug_loops (3) I selected the region of
code containing both the original loops: loop_3 and loop_4 and the
code generated by graphite with -fgraphite-identity: loop_22, loop_23.

In loop_22 the computation on connection$dim$1$lbound disappears.
I wonder what this variable stands for: it is not used elsewhere in the
debug_loops (3) output of change_bond_length function, and I suspect
that this is a global variable whose value is needed elsewhere outside
the change_bond_length function.

The bug is in the detection of scalar reductions.

Sebastian

Subject: Re:  [graphite] several ICEs with CP2K (summary)

Thanks for the clarification, I managed to reproduce the fail.  The
problem comes from the fact that we do not generate code for a scalar
reduction that is not detected as a scalar reduction with the variable
connection$dim$1$lbound.

In the attached output from debug_loops (3) I selected the region of
code containing both the original loops: loop_3 and loop_4 and the
code generated by graphite with -fgraphite-identity: loop_22, loop_23.

In loop_22 the computation on connection$dim$1$lbound disappears.
I wonder what this variable stands for: it is not used elsewhere in the
debug_loops (3) output of change_bond_length function, and I suspect
that this is a global variable whose value is needed elsewhere outside
the change_bond_length function.

The bug is in the detection of scalar reductions.

Sebastian

This variable is a local, I believe, it is part of the array descriptor of the
(local variable):
INTEGER, ALLOCATABLE, DIMENSION(:, :)    :: connection

while I'll apply it to current trunk, retest CP2K, and update this PR with the
results.

Looks like all CP2K tests pass with this patch installed!
