Checkpointing protocols have different energy consumption depending on parameters like application features and platform characteristics. To select a protocol for a given execution, we propose an energy estimator that relies on an energy calibration of the considered platform and a user description of the execution settings.
Future supercomputers will gather hundreds of millions of communicating cores. The movement of data in such systems will be very energy consuming. We address in this paper the issue of energy consumption of data broadcasting in such large scale systems. To this end, we propose a framework to estimate the energy consumed by different MPI broadcasting(More)
