Hi, Foamers!

MPI error with damBreak fine mesh sample on openfoam7 with message "unable to create shared memory BTL coordinate structure",singularity instance stopping only manually, on openfoam2006 mpi failed with "Bus error" if I increase mesh cell number 10 times, basic sample work and 4 times increase work

singularity container build from docker container at home computer with same version docker and singularity as on sumercomputer
OS Centos 7 at home RedHat on supercomputer. sample run on one node with 39 core and 768 GB RAM
How solve this problem?




FOAM_SINGULARITY_IMAGE=work/OPENFOAM_7_SINGULARITY/openfoam7.sif
FOAM_BASHRC=/opt/openfoam7/etc/bashrc
singularity instance start ://openfoam7 --cleanenv

singularity exec $FOAM_SINGULARITY_IMAGE bash -c "source $FOAM_BASHRC && blockMesh -case damBreak"

singularity exec $FOAM_SINGULARITY_IMAGE bash -c "source $FOAM_BASHRC && setFields -case damBreak"

singularity exec $FOAM_SINGULARITY_IMAGE bash -c "source $FOAM_BASHRC && decomposePar -case damBreak"


singularity exec $FOAM_SINGULARITY_IMAGE bash -c "source $FOAM_BASHRC && mpirun -np 4 interFoam -parallel -case damBreak
singularity instance stop
