To demonstrate the viability and robustness of the proposed interface and instrumentation tools we have developed, the OPARI tool and the pomp libraries for EXPERT and TAU are applied to example mixed-mode (OpenMP + MPI) applications. These types of application present an analysis challenge for performance tools because of the need to capture and present performance data for different parallel modes and their interaction.
