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 |
