Hello, I am trying to implement some graceful application shutdown in case mpirun receives a SIGTERM. With Open MPI 4.x, this works just fine, and SIGTERM is forwarded. With Open MPI 5.x I now struggle as prte seems not to forward SIGTERM by default. If I try to include this in the list of SIGNALS to be forwarded, I get the following error
mpirun -n 2 --forward-signals SIGTERM stopsignal -------------------------------------------------------------------------- The system does not support trapping and forwarding of the specified signal: signal: SIGTERM param: (null) Please remove that signal from the ess_base_forward_signals MCA parameter. -------------------------------------------------------------------------- The documentation/mpirun manpages for Open MPI 5.0 does not help here and seem outdated. Any suggestions on how to get this working, or is this an issue to be raised on GitHub?
