Hub_DF_square_nnn Seg Fault about opendf HOT 8 CLOSED

log suggests crash is due to resume failure.

script has text '--resume > log' which should be '--resume 1 > log'

Regardless, code SHOULD respond that --resume needs an argument.

Cannot reproduce error. So far checked revision from november ( 273428d )

Will check updated version.

from opendf.

Appears to work on updated opendf - linked against ALPSCore 0.5.4

Could be change in alpscore causing issue. Will followup.

Workaround - Install ALPSCore 0.5.4 and compile opendf linked to that, see if error vanishes.

works on ALPSCore jan 5th revision. checking most up to date.

Updated ALPSCore appears to work.

I'm not happy now that I look at the log with seeing the mention of 'pthreads'. Probably something in alps is using mpi, and opendf was not compiled with MPI.

Recommend installing ALPSCore with minimal options, MPI enabled, and compile opendf ALSO with mpicxx compiler.

Example script:

export ALPSCore_DIR=/home/jpfleblanc/alps_core/ALPSCore_updated/install
CC=mpicc CXX=mpicxx cmake
-DCMAKE_INSTALL_PREFIX=${ALPSCore_DIR}
-DENABLE_MPI=ON
-DCMAKE_CXX_FLAGS="-DNDEBUG -DBOOST_DISABLE_ASSERTS -DALPS_GF_DEBUG"
-DCMAKE_BUILD_TYPE="Release" ..

and then compile opendf

CC=mpicc CXX=mpicxx cmake -DALPSCore_DIR=/home/jpfleblanc/alps_core/ALPSCore_updated/install/share/ALPSCore/ -DCMAKE_INSTALL_PREFIX=/home/jpfleblanc/alps_core/opendf_debug/opendf/install/ -DCMAKE_BUILD_TYPE=RELEASE ..

Please let me know if this is not the issue.

I did compile both ALPSCore and OpenDF with the same mpicc and mpicxx. Here's exactly what I did:

ALPSCore:
HDF5_ROOT=/u/shared/ALPSCore_stuff/software/install/ CC=mpicc CXX=mpicxx cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/u/shared/ALPSCore_stuff/install/ -DCMAKE_CXX_FLAGS="-DNDEBUG -DBOOST_DIABLE_ASSERTS -DALPS_GF_DEBUG" -DBOOST_ROOT=/u/shared/ALPSCore_stuff/software/install/ -DBoost_NO_SYSTEM_PATHS=ON -DBoost_NO_BOOST_CMAKE=ON -DENABLE_MPI=ON ..
make
make install

OpenDF:
HDF5_ROOT=/u/shared/ALPSCore_stuff/software/install/ CC=mpicc CXX=mpicxx cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/u/shared/ALPSCore_stuff/install/ -DALPSCore_DIR=/u/shared/ALPSCore_stuff/install/share/ALPSCore/ -DEIGEN3_INCLUDE_DIR=/u/shared/ALPSCore_stuff/software/install/include/eigen3 -DFFTW_ROOT=/u/shared/ALPSCore_stuff/software/install -DCMAKE_CXX_FLAGS="-DNDEBUG -DBOOST_DIABLE_ASSERTS -DALPS_GF_DEBUG" ..
make
make install

Running OpenDF:
/u/shared/ALPSCore_stuff/install/bin/hub_df_square_nnn --input qmc_output.h5 --df_sc_cutoff 1.0e-8 --df_sc_iter 1200 --df_sc_mix 0.2 --fluct_diag 0 --nbosonic 32 --add_lattice_bubble 0 --mu 0.375 --tp 0.0 --resume 1

But this gives me the same seg fault error. Any other ideas for what to try / information I could give you guys to identify the problem? (James, this is all on Shakuras, in case you want to try it out yourself.)

After carefully recompiling OpenDF and all of its dependencies, the problem seems to have gone away. As you said, I had probably just used a different compiler for one of the dependencies.
