Member Function Documentation

◆ createCpu()

virtual Cpu* simgrid::surf::CpuModel::createCpu	(	simgrid::s4u::Host *	host,
		std::vector< double > *	speedPerPstate,
		int	core
	)

pure virtual

Create a Cpu.

Parameters

host	The host that will have this CPU
speedPerPstate	Processor speed (in Flops) of each pstate. This ignores any potential external load coming from a trace.
core	The number of core of this Cpu

Implemented in simgrid::surf::CpuTiModel, simgrid::surf::CpuL07Model, and simgrid::surf::CpuCas01Model.

◆ updateActionsStateLazy()

void simgrid::surf::CpuModel::updateActionsStateLazy	(	double	now,
		double	delta
	)

overridevirtual

Reimplemented from simgrid::surf::Model.

◆ updateActionsStateFull()

void simgrid::surf::CpuModel::updateActionsStateFull	(	double	now,
		double	delta
	)
