AB  - 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.
