We develop a new energy-aware methodology to improve the energy
consumption of a task-parallel preconditioned Conjugate Gradient iter-
ative solver on a Haswell-EP Intel Xeon. This technique leverages the
power-saving modes of the processor and the frequency range of the
userspace Linux governor, modifying the CPU frequency for some oper-
ations. We demonstrate that its application during the main operations
of the PCG solver can reduce its energy consumption. [-]
