Claim of US Patent No. 10,512,196

1. An apparatus comprising:power thermal awareness solution (PTAS) circuitry to:
receive information regarding a configuration for each of a plurality of cooling zones, each cooling zone including at least one fan, each cooling zone is associated with one or more devices;
initiate a test procedure that includes:
set a range of pulse width modulation (PWM) duty cycles for each fan in each cooling zone;
determine, for each PWM duty cycle, a fan speed for each fan in each cooling zone; and
determine, for each PWM duty cycle, a measured volumetric air flow associated with each cooling zone; and
for each cooling zone,
select an airflow prediction model from a plurality of airflow prediction models based at least in part on the measured volumetric airflow information for each cooling zone; and
determine, during operation of each cooling zone and the associated one or more device, an operational volumetric airflow based at least in part on the selected airflow prediction model for the cooling zone; and
cause a workload assigned to at least one of the one or more devices to be modified based on the operational volumetric airflow of each cooling zone.
