In exascale scientic computing, it is essential to eciently monitor, evaluate and improve performance. Visualization and especially visual analytics are useful and necessary techniques in the exascale computing era to enable and enhance such a human-centered experience. In this work, we devise a visualization platform for performance evaluation of scientic workows toward the exascale scenario. We rst improve Tau instrumentation toolset to accommodate workow measurements. en we design new visualization methods to show trace and prole information of the workow. In order to support the scalability, a few level-of-detail visual methods are proposed with user interactions. Finally, an NWChem use case is adopted to verify our methods.
