Open FG-TUM opened 2 years ago

FG-TUM commented 2 years ago

Issue

The problem

The timeout mechanic could potentially cause a deadlock with MPI: https://github.com/esa/LADDS/blob/220d60e795ac4904875d1aff23721d46bc12fa6f/src/ladds/Simulation.cpp#L391-L401

Expected behavior

No Deadlock

What needs to be done

[ ] Testing
[ ] Synchronization if necessary

How it can be tested or reproduced

Run a simulation that hits a timeout.
