Detailed Description

template<class TagName>
class MueLu::MutuallyExclusiveTime< TagName >

This class wraps a Teuchos::Time and maintains a mutually exclusive property between wrapped timers.

This class is useful to exclude from a timer the execution time of a subroutine; when a MutuallyExclusiveTime is running, other timers are not running. Timers have three states (running, stopped, paused) to enforce the mutually exclusive property. When the running timer is stopped, the last active timer is restarted. A stack of timers is used internally to support this functionality. The template parameter of this class can be used to define several sets of mutually exclusive timers.

Note: Only one timer can be active at a time but all timers can be inactive at the same time. Timers cannot be destroyed when they are in 'paused'.

template<class TagName >

MueLu::MutuallyExclusiveTime< TagName >::MutuallyExclusiveTime	(	const std::string &	name,
		bool	startFlag = `false`
	)

Constructor.

Definition at line 31 of file MueLu_MutuallyExclusiveTime.cpp.

template<class TagName >

MueLu::MutuallyExclusiveTime< TagName >::~MutuallyExclusiveTime ( )

Destructor.

Definition at line 41 of file MueLu_MutuallyExclusiveTime.cpp.

template<class TagName >

MueLu::MutuallyExclusiveTime< TagName >::MutuallyExclusiveTime ( RCP< Teuchos::Time > timer )

private

This constructor is not public to prevent users from using Teuchos::Time::start()/stop() instead of MutuallyExclusiveTime::start()/stop(), if they have access to the underlying Teuchos::Time object.

Member Function Documentation

template<class TagName >

void MueLu::MutuallyExclusiveTime< TagName >::start ( bool reset = false )

Starts the timer. If a MutuallyExclusiveTime timer is running, it will be stopped.

Precondition: Timer is not already paused.

Postcondition: Timer is running. Other MutuallyExclusiveTime timers are paused or stopped.

Definition at line 53 of file MueLu_MutuallyExclusiveTime.cpp.

template<class TagName >

double MueLu::MutuallyExclusiveTime< TagName >::stop ( )

Stops the timer. The previous MutuallyExclusiveTime that has been paused when this timer was started will be resumed. This method can be called on an already stopped timer or on the currently running timer.

Definition at line 78 of file MueLu_MutuallyExclusiveTime.cpp.

template<class TagName >

void MueLu::MutuallyExclusiveTime< TagName >::pause ( )

Pause running timer. Used internally by start().

Definition at line 101 of file MueLu_MutuallyExclusiveTime.cpp.

template<class TagName >

void MueLu::MutuallyExclusiveTime< TagName >::resume ( )

Resume paused timer. Used internally by stop(). Timer is not reset.

Precondition: Timer is at the top of the stack.

Definition at line 112 of file MueLu_MutuallyExclusiveTime.cpp.

template<class TagName >

bool MueLu::MutuallyExclusiveTime< TagName >::isRunning ( )

Definition at line 124 of file MueLu_MutuallyExclusiveTime.cpp.

template<class TagName >

bool MueLu::MutuallyExclusiveTime< TagName >::isPaused ( )

Definition at line 133 of file MueLu_MutuallyExclusiveTime.cpp.

template<class TagName >

RCP< MutuallyExclusiveTime< TagName > > MueLu::MutuallyExclusiveTime< TagName >::getNewTimer ( const std::string & name )

static

Return a new MutuallyExclusiveTime that is registered with the Teuchos::TimeMonitor (for timer summary).

Definition at line 139 of file MueLu_MutuallyExclusiveTime.cpp.

template<class TagName >

void MueLu::MutuallyExclusiveTime< TagName >::incrementNumCalls ( )

Increment the number of times this timer has been called.

Definition at line 146 of file MueLu_MutuallyExclusiveTime.cpp.

template<class TagName >

void MueLu::MutuallyExclusiveTime< TagName >::PrintParentChildPairs ( )

static

Print std::map of (child,parent) pairs for post-run analysis.

This method print a std::map. Each key is a child, and the value is its parent. The (child,parent0) pairs can be used by the MueLu script ``mueprof.sh" to print a nice hierarchical tree that shows both runtime flow and time for each section.

Definition at line 149 of file MueLu_MutuallyExclusiveTime.cpp.

template<class TagName >

void MueLu::MutuallyExclusiveTime< TagName >::TopOfTheStack ( )

private

Check if 'this' is the head of the stack.
