Designing Energy-Aware MPI Communication Library: Opportunities and Challenges
Feb. 9, 2016
Dhabaleswar K. (DK) Panda, Ohio State UniversityPower is considered the major impediment in designing the next-generation exascale systems. In recent years, the TOP500 and Green500 lists have been focusing on both performance and power consumption. To address the power challenge, researchers and engineers are proposing solutions along multiple directions including: 1) exploring revolutionary architectures that compute at near threshold voltage (NTV) to minimize leakage power; 2) developing user-controlled mechanisms to control power (power levers) such as dynamic voltage and frequency scaling (DVFS), and core-idling; 3) increasing the efficiency of cooling subsystems; 4) extending the job scheduler and resource management schemes …
