Exactly one participant needs to take `control` of the coupling. preCICE computes the convergence measures and the acceleration on this participant.
Exactly one participants needs to have `control`. preCICE computes the convergence measures and the acceleration on this participant. The controller participant needs to access all the data that is used in the acceleration and convergence measures. Therefore, related `m2n` connections and `exchange` tags should be properly configured. Currently, parallel participants are not supported to be used in multi-coupling scheme.

Prior to version 2.3.0, this controlling participant needs to be centric.
