Please see the attachments for the Par_file I used and the output generated
by the run.

thanks for the outputs! it seems to be a problem with the Stacey absorbing boundary setup becoming blocking when there are partitions without boundary elements. please try the updated version here on the devel branch - it should work now with PR #1136 |

Thank you for the updates. I tried in on our nodes with 16 cores. It is
working fine now.

Who may concern
I am running into a problem when I run the xspecfem2D using mpirun. I can run the code using 8 cores. However, if I would like to use more cores, say 16 cores, the xpecfem2D will run until the output says
"Preparing array allocations
arrays for elastic domains
done initialization"
Then it will hold it there, with no error output and no calculation results. I have talked to my department's IT group and we did not find any issues with the hardware side.
Does anyone of you meet this issue or can you help me figure it out?
