In the sample that code I am trying to run using mpirun, the mpi_init gives me an “error attaching to the shared memory object as a slave; Permission denied” message.
Is this because I killed the hanging processes on the cluster nodes. Does this not clear the shared memory usage?
Why is it that ipcs does not show any shared memory segments?
Is there a way to release the shared memory and clean up so I can run the mpirun command?
