      abstract     = {The MPI 4.0 standard introduced the concept of partitioned
                      point-to-point communication. One facet that may help in
                      encouraging application developers to use this new concept
                      in their programs is the availability of proper tool support
                      in a timely manner. In this paper, we therefore propose nine
                      new events extending the OTF2 event model to accurately
                      represent the runtime behavior of partitioned point-to-point
                      communication. We then demonstrate the suitability of these
                      extensions with three different use cases in the context of
                      performance analysis. In particular, we showcase a prototype
                      implementation of an extended waitstate analysis in the
                      Scalasca trace analyzer, and discuss further potential use
                      cases in the realm of trace visualization and simulation.},
