Linktest does not work with OpenMPI, intialization fails
On JURECA, with OpenMPI/4.1.0rc1
, linktest will not start with the following error message:
*** An error occurred in MPI_Init
*** on a NULL communicator
*** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort,
*** and potentially your MPI job)
[jrc0510.jureca:31981] Local abort before MPI_INIT completed completed successfully, but am not able to aggregate error messages, and not able to guarantee that all other processes were killed!
srun: error: jrc0511: task 1: Terminated
srun: error: jrc0510: task 0: Exited with exit code 1
srun: Force Terminated job step 8964121.0
