Detailed Description

Base class for solver monitors.

The solver monitors serve for monitoring a convergence and status of various solvers. The solver monitor uses separate thread for monitoring the solver status in preset time period.

Member Function Documentation

isStopped()

bool TNL::Solvers::SolverMonitor::isStopped ( ) const

inlinenodiscard

Checks whether the main loop was stopped.

Returns

true if the main loop was stopped.

false if the main loop was not stopped yet.

refresh()

virtual void TNL::Solvers::SolverMonitor::refresh ( )

pure virtual

This abstract method is responsible for printing or visualizing the status of the solver.

Implemented in TNL::Solvers::IterativeSolverMonitor< Real >, TNL::Solvers::IterativeSolverMonitor< double >, TNL::Solvers::IterativeSolverMonitor< gko::default_precision >, and TNL::Solvers::IterativeSolverMonitor< typename Vector::RealType >.

setRefreshRate()

void TNL::Solvers::SolverMonitor::setRefreshRate ( const int & refreshRate )

inline

Set the time interval between two consecutive calls of SolverMonitor::refresh.

Parameters

refreshRate

refresh rate in milliseconds.

setTimer()

void TNL::Solvers::SolverMonitor::setTimer ( Timer & timer )

inline

Set a timer object for the solver monitor.

If a timer is set, the monitor can measure real elapsed time since the start of the solver.

Parameters

timer

is an instance of TNL::Timer.
