Abstract:While transitioning to exascale systems, it has become clear that power management plays a fundamental role to support a viable utilization of the underlying hardware, also performance-wise. To meet power restrictions imposed by future exascale supercomputers, runtime environments will be required to enforce self-tuning schemes to run dynamic workloads under an imposed power cap. Literature results show that, for a wide class of multi-threaded applications, tuning both the degree of parallelism and frequency/ … Show more
