Member Function Documentation

adjust_platform()

void geopm::PowerGovernorImp::adjust_platform ( double  node_power_request, double &  node_power_actual  )

overridevirtual

Calculates metric of DRAM power history, subtracting that value from the provided target node power.

Parameters

[in]	node_power_request	Total expected node power consumption.
[out]	node_power_actual	Achievable node power limit. Should equal

Returns

True if platform adjustments have been made, false otherwise.

Implements geopm::PowerGovernor.

do_write_batch()

bool geopm::PowerGovernorImp::do_write_batch ( void  ) const

overridevirtual

Implements geopm::PowerGovernor.

init_platform_io()

void geopm::PowerGovernorImp::init_platform_io ( void  )

overridevirtual

Registsters signals and controls with PlatformIO.

Implements geopm::PowerGovernor.

power_package_time_window()

double geopm::PowerGovernorImp::power_package_time_window ( void  ) const

overridevirtual

Get the time window for controlling package power.

Returns

Time window in units of seconds.

Implements geopm::PowerGovernor.

sample_platform()

void geopm::PowerGovernorImp::sample_platform ( void  )

overridevirtual

To be called inside of the Agent's sample_platform() method to read any values required when calling adjust_platform(). This method is currently a noop since no signals are required for this algorithm.

Implements geopm::PowerGovernor.

set_power_bounds()

void geopm::PowerGovernorImp::set_power_bounds ( double  min_pkg_power, double  max_pkg_power  )

overridevirtual

Sets min and max package bounds.

Parameters

[in]	min_pkg_power	Minimum package power.
[in]	max_pkg_power	Maximum package power.

Implements geopm::PowerGovernor.
