Hi Rainer

a reason for such segmentation faults is often a too small stack size. Check your stack size limit with (e,g. for bash with “ulimit –s”). It should be a large value or “unlimited”. I am using the latter setting.

Hi.

My name is Rainer. I am a cluster admin at the

University of Konstanz/Germany.



Last week i got the order to build cp2k for our

Chemical Cluster Justus. Compillation was fine,

I got no errors in the build process.



Unfortunately the tests are not running. I get





These are the modules i load:



# Load required modules for build process

module load compiler/intel/19.1

module load compiler/gnu/system

module load mpi/openmpi

module load numlib/mkl

module load devel/cmake



Toolchain options i used:



# ./install_cp2k_toolchain.sh \

  --math-mode=openblas \

  --with-sirius=no \

  --mpi-mode=openmpi \

  --with-cmake=system \

  --with-mpich=no \

  --with-libxc=install \

  --libint-lmax=6 \

  --with-fftw=install \

  --with-openblas=install \

  --with-scalapack=install \

  --with-reflapack=no \

  --with-mkl=no \

  --with-libxsmm=install \

  --with-elpa=no \

  --with-superlu=install \

  --with-quip=install \

  --with-plumed=install \

  --with-gsl=install \

  --with-libvdwxc=install \

  --with-spglib=install \

  --with-hdf5=install
