Report on energy consumption evaluation. Deliverable D4.2 of the HORIZON-EUROHPC-JU-2021-COE-01 project MaX (101093374)

The deliverable's objection is to evaluate the energy efficiency of MaX codes on various HW platforms. Energy efficiency is defined as average performance (Floating point operations per second (FLOPs)) per average power consumption (Watt). The FLOPs are measured using performance counters, which are platform-dependent, measured from the complete application execution. The obtained results must be comparable despite each hardware platform providing a different power monitoring solution. For that reason, the energy consumption of the whole compute node is reported. To improve the energy efficiency of the MaX applications, static tuning of hardware power knobs was done on a subset of hardware platforms.
