Can MPI communication runtimes be designed to be energy-aware? Can energy be saved during MPI calls without a loss in performance? These are two questions briefly examined by Dhabaleswar K. (DK) Panda, of The Ohio State University, in a blog post on the Top500 website today (Designing Energy-Aware MPI Communication Library: Opportunities and Challenges). Power, Read more…
