Detailed Description

SURF cpu model interface class.

A model is an object which handle the interactions between its Resources and its Actions

Member Function Documentation

virtual Cpu* simgrid::surf::CpuModel::createCpu ( simgrid::s4u::Host *  host,
xbt_dynar_t  speedPerPstate,
int  core 
)
pure virtual

Create a Cpu.

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

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

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

Reimplemented from simgrid::surf::Model.

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

Reimplemented from simgrid::surf::Model.

bool simgrid::surf::CpuModel::next_occuring_event_isIdempotent ( )
inlinevirtual

Returns whether this model have an idempotent shareResource()

The only model that is not is NS3: computing the next timestamp moves the model up to that point, so we need to call it only when the next timestamp of other sources is computed.

Implements simgrid::surf::Model.
