Detailed Description
Select frequency control settings that are expected to balance measured execution times. Assumes time impact of up to (frequency_old/frequency_new) percent. Workloads less frequency-sensitive than that should be able to go lower than the recommended frequencies. This is expected to converge toward those lower frequencies if it is repeatedly re-evaluated some time after applying the recommended frequency controls.

Return the recommended frequency controls given observed times while operating under a given set of previous frequency controls. The returned vector is the same size as the input vectors.
- Parameters
-
previous_times Time spent in the region to be balanced, measured by any domain. previous_control_frequencies Frequency control last applied over the region to be balanced, measured by the same domain as previous_times.previous_achieved_frequencies Average observed frequencies over the region to be balanced, measured by the same domain as previous_times.
Implemented in geopm::FrequencyTimeBalancerImp.
◆ get_target_time()
|
pure virtual |
return the target time last used to balance the frequencies.
Implemented in geopm::FrequencyTimeBalancerImp.
◆ make_shared()
|
static |
Allocate a FrequencyTimeBalancer instance.
- Parameters
-
minimum_frequency The lowest frequency control to allow in rebalancing frequency control decisions. maximum_frequency The highest frequency control to allow in rebalancing frequency control decisions.
◆ make_unique()
|
static |
Allocate a FrequencyTimeBalancer instance.
- Parameters
-
minimum_frequency The lowest frequency control to allow in rebalancing frequency control decisions. maximum_frequency The highest frequency control to allow in rebalancing frequency control decisions.
