Original Abstract

This paper introduces the READEX project tuning approach which exploits the dynamic application behavior and its potential for energy savings. The paper is focused on themanual applications evaluation from the energy consumption optimisation point of view. As an examples we have selected one complex application, the ESPRESO library and two simplified applications from the ProxyApps benchmark tool suite. ESPRESO containsmany types of operations including I/O, communication, sparse BLAS and dense BLAS. The results show that static savings are 5.6-12.3% and dynamic savings are 4.7-9.1%. The highest total savings for ESPRESO are 21.4% as a combination of 12.3% static savings and 9.1% dynamic savings. The ProxyApp applications, Kripke and Lulesh, were presented for two configurations each. The first configuration of the Kripke saved 29.3% energy, almost only by static tuning. On the other hand, the second configuration shows us only 18.8% savings, but over a third of it was saved by dynamic switching CPU core and uncore frequencies. The Lulesh test cases saved 28.9%, respectively 26.7%.
