On the way to exascale systems, the usage of energy will be a crucial aspect. New approaches are needed to make HPC systems more energy efficient. System monitoring and management can not only help to optimize the usage of computing resources with a supercomputer, but also boost energy efficiency in HPC. In this episode of the DEEP podcast, Dr. Michael Ott from the Leibniz Supercomputing Centre will talk about the issues of system monitoring in HPC.
