I have a script which runs fine on 1 node (24 cores) but fails on 2 or more.

It seems to die somewhere during the extruded mesh generation, with messages such as

OSError: /tmp/pyop2-cache-uid15427/9d8ebf65631aa626aeb3cd8098e2662f.so: cannot open shared object file: No such file or directory

Full output and error files attached.
