hi - I have an application that consistently segfault when I do "mpirun --oversubscribe" and the following message came AFTER application runs. My running environment: MacOS with openmpi 3.1.2.
Is this a problme with my application? or my environment? any help? thanks Oliver -------------------------------------------------------------------------- A system call failed during shared memory initialization that should not have.
