It requires performance analysis made even more complex by the lack of (projections of) such exascale systems. However, many tools have been developed to this end, but in an uncoordinated way, each having its own focus, strengths, and limitations.=0A=0AThis BoF has two goals. First, we invite potential users for an informative overview of the existing tools through a series of short talks. Second, we gather tool developers to set up a working group to favor interoperability and foster cross-fertilization. SUMMARY:Performance Analysis and Simulation of MPI Applications and Runtimes at Exascale PRIORITY:3 END:VEVENT END:VCALENDAR
