The Periscope Tuning Framework (PTF) is a scalable online automatic tuner and analyzer of HPC applications' performance and energy. PTF performs automatic online search for performance bottlenecks and, when requested, automatically searches for an optimum of a given tuning objective by evaluating a space of tuning alternatives. At the end of the experiment, detailed recommendations are given to the code developer on how to apply the identified optimal configurations in production runs. Also detected performance bottlenecks, called properties, can be displayed in the PTF GUI.
