Modules implementing energy probes (via the
EnergyProbe interface) must be positioned
in the evowluator/user/probes directory. This last step is only necessary
for energy footprint evaluation. Note that evOWLuator comes with two built-in probes that wrap
the powermetrics and powertop tools on macOS and GNU/Linux, respectively.
evOWLuator estimates energy consumption by running the reasoner binary and polling the probe until the process exits. The collected samples are then used to compute an energy footprint score as follows:
This provides a proxy of the energy used by the reasoner during its execution time, which can be leveraged for comparisons among reasoners run on the same device and using the same probe.
