Examples all end with SIGSEGV #512

lopsided · 2021-09-14T15:11:53Z

Hi,

I'm trying to test my installation and check the different solvers are compiled correctly, but every one exits with Segmentation fault (core dumped).

This is an example log from journalctl:

[datetime] [pcname] systemd-coredump[458973]: [🡕] Process 458971 (hs071_c) of user 1000 dumped core.
                                                 Stack trace of thread 458971:

Some examples show the licence and the selected solver. In ScalableProblems I see the Number of nonzeros in.... lines and larger problems seem to take longer at least, but I can't tell if they are completing and just not exiting properly or if they are actually failing.

The text was updated successfully, but these errors were encountered:

Also (hopefully related) I'm seeing lots of failures in make test (including some seg faults):

Maybe try a debug build (--enable-debug --disable-shared) and run under valgrind.

points to this line in Ipopt::DenseVector::AmaxImpl():

   return std::abs(values_[IpBlasIamax(Dim(), values_, 1) - 1]);

Somehow IpBlasIamax, which just calls idamax from BLAS, seems to return 0 instead of some index >= 1, so the code tries to access values_[-1] ("8 bytes before a block of size 8 alloc'd").

Indices in BLAS are 1-based and Dim()>0 here, so something fishy seems to go on in your BLAS installation.

I'm trying to compile with MKL blas, but I don't think it is working. I've downloaded the MKL libs and can see the .so files in /opt/intel/oneapi/mkl/latest/lib/intel64. So I export MKLROOT=/opt/intel/oneapi/mkl/latest and then configure again with:

../configure --prefix=${PWD} --with-hsl-lflags="-L${HSLDIR}/.libs -lcoinhsl" --with-hsl-cflags="-I${HSLDIR}" \
  --with-lapack-lflags="-L${MKLROOT}/lib/intel64 -Wl,--no-as-needed -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lm"

as per the ipopt instructions. But in the configure output I see:

checking for LAPACK... yes: generic module (lapack.pc blas.pc)

Does this mean it didn't find MKL and is just using the netlib/openblas versions?

(Tests still segfault as before)

svigerske · 2021-09-15T12:36:47Z

There seems to be something wrong in configure that it didn't pick up your flags. I'll fix. But in the meanwhile, change --with-lapack-lflags to --with-lapack.

Figuring out what the issue could be with your /usr/lib/libblas.so.3 would also be worthwile. Maybe you installed a blas with 64-bit integers by accident.

lopsided · 2021-09-15T13:06:52Z

with
../configure --prefix=${PWD} --with-hsl-lflags="-L${HSLDIR}/.libs -lcoinhsl" --with-hsl-cflags="-I${HSLDIR}" --with-lapack="-L${MKLROOT}/lib/intel64 -Wl,--no-as-needed -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lm"

I get:
checking for LAPACK... yes: user-specified (-L/opt/intel/oneapi/mkl/latest/lib/intel64 -Wl,--no-as-needed -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lm)

and also:
checking for function pardiso_ in -L/opt/intel/oneapi/mkl/latest/lib/intel64 -Wl,--no-as-needed -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lm ... yes

But it is not in the library search path. Add MKLROOT to you LD_LIBRARY_PATH.

I see! OK that gets me back to some tests failing with segfaults still. Full vagrind debug output here: https://pastebin.com/zvtJ7g4D

And you have also rebuild HSL to use MKL?

That fixed it! Happy days :)

$ ./run_unitTests

So I guess there is a problem with openblas from the fedora 34 repos. I saw a few tickets on it (eg, OpenMathLib/OpenBLAS#2839) though I can't tell if they are related. But at least the issues seem fixed with MKL.

Thanks for all your help and patience!

Interesting development. I recompiled without --enable-debug --disable-shared. The tests still pass, but the examples are now giving seg faults again!

Recompiling with the --disable-shared flag fixes the examples again.

svigerske · 2021-09-15T14:19:03Z

Did you install before building the examples?

lopsided · 2021-09-15T14:21:00Z

Yes, I think it fails otherwise..?

svigerske · 2021-09-15T14:22:30Z

Or the examples are build against some older Ipopt installation.
Check what libraries the examples depend on.

Could also be that there are now both (broken) shared and (working) static libs installed, but the examples link against the shared libs.
