We investigate the benefits that an energyaware
implementation of the runtime in charge of
the concurrent execution of ILUPACK —a sophisticated
preconditioned iterative solver for sparse linear
systems— produces on the time-power-energy balance
of the application. Furthermore, to connect the
experimental results with the theory, we propose several
simple yet accurate power models that capture
the variations of average power that result from the
introduction of the energy-aware strategies as well as
the impact of the P-states into ILUPACK’s runtime,
at high accuracy, on two distinct platforms based on
multicore technology from AMD and Intel. [-]
