Member Function Documentation

adjust_platform()

virtual void geopm::SSTClosGovernor::adjust_platform ( const std::vector< double > &  clos_by_core )

pure virtual

Write CLOS controls.

Parameters

[in]

clos_by_core

Desired per-core CLOS.

Implemented in geopm::SSTClosGovernorImp.

clos_domain_type()

virtual int geopm::SSTClosGovernor::clos_domain_type ( void  ) const

pure virtual

Get the domain type of CLOS control on the platform. Users of the SSTClosGovernor can use this information to determine the size of the vector to pass to adjust_platform().

Returns

The domain with which CLOS will be governed.

Implemented in geopm::SSTClosGovernorImp.

disable_sst_turbo_prioritization()

virtual void geopm::SSTClosGovernor::disable_sst_turbo_prioritization ( )

pure virtual

Disable prioritized turbo frequency and core priority features. This is a no-op if those features are not supported on the platform.

Implemented in geopm::SSTClosGovernorImp.

do_write_batch()

virtual bool geopm::SSTClosGovernor::do_write_batch ( void  ) const

pure virtual

Returns true if the last call to adjust_platform requires writing controls.

Returns

True if platform adjustments have been made, false otherwise.

Implemented in geopm::SSTClosGovernorImp.

enable_sst_turbo_prioritization()

virtual void geopm::SSTClosGovernor::enable_sst_turbo_prioritization ( )

pure virtual

Enable prioritized turbo frequency and core priority features. This is a no-op if those features are not supported on the platform.

Implemented in geopm::SSTClosGovernorImp.

init_platform_io()

virtual void geopm::SSTClosGovernor::init_platform_io ( void  )

pure virtual

Registers signals and controls with PlatformIO using the default control domain.

Implemented in geopm::SSTClosGovernorImp.

is_supported()

bool geopm::SSTClosGovernor::is_supported ( PlatformIO &  platform_io )

static

Indicate whether this platform supports core priority and prioritized turbo frequency limits.

make_shared()

std::shared_ptr< SSTClosGovernor > geopm::SSTClosGovernor::make_shared ( void  )

static

make_unique()

std::unique_ptr< SSTClosGovernor > geopm::SSTClosGovernor::make_unique ( void  )

static
