Is it possible for preCICE to visualize the load balancing of my individual solvers during parallel coupling schemes? There are various ways to change the workload of individual solvers and it would be nice to see/improve it for the coupled simulation.

I am currently updating to the most recent version and I know there have been changes, so I am not sure about this: But also for serial schemes, it would be nice to know, which solver spend how much time for his computation. The final output of my last preCICE version was just too extensive i.e. I couldn’t find the information.

Yes, you can visualize that. You need to convert the preCICE events to a standard tracing output and then use e.g. the chromium browser tool `chrome://tracing`. More information in the [wiki](https://github.com/precice/precice/wiki/Performance-Measurements). Please let us know if the documentation there is not enough.
