MPI Sync timeout?

[FG-TUM]

Issue

The problem

The timeout mechanic could potentially cause a deadlock with MPI:

LADDS/src/ladds/Simulation.cpp

Lines 391 to 401 in 220d60e

	if (secondsSinceStart > timeout) {
	// FIXME: MPI SYNC THIS?
	SPDLOG_LOGGER_INFO(logger.get(),
	"Simulation timeout hit! Time since simulation start ({} s) > Timeout ({} s))",
	secondsSinceStart,
	timeout);
	// set the config to the number of completed iterations (hence no +/-1) for the timer calculations.
	config.setValue("sim/iterations", iteration);
	// abort the loop by increasing the loop counter. This also leads to triggering the visualization
	iteration = lastIteration;
	}

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.
