Description
This presentation provides an overview of the use of tools for verifying parallel performance and correctness at the DLR institute in Dresden.
Typical use cases, examples of identified bottlenecks and their performance impact as well as problems uncovered are shown for both individual and coupled applications.
Additionally, automated builds are demonstrated for coupled problems involving deep dependency stacks, ranging from non-instrumented stacks through builds with just one instrumented library to fully instrumented software stacks.
