Is your software ready for exascale? – How the next generation of performance tools can give you the answer
Traditional performance tools do a great job of evaluating the performance of a code for a given execution configuration on an existing machine. However, foresighted developers want to validate their design decisions and implementations also for future problem and machine sizes – and if needed revise their code as early as possible. In this talk, we will discuss new techniques for automated performance modeling and present case studies demonstrating their potential. As one of our examples, we will show how to systematically validate the scalability of state-of-the-art MPI implementations and put existing performance expectations to the test.
