Member Function Documentation

dumpCurrentStats()

virtual void Arcane::ITimeStats::dumpCurrentStats ( const String & name )

pure virtual

Displays statistics for an action.

Displays the statistics for action name as well as its sub-actions for the current iteration.

dumpStats()

virtual void Arcane::ITimeStats::dumpStats ( std::ostream & ostr, bool is_verbose, Real nb, const String & name, bool use_elapsed_time = false )

pure virtual

Displays execution time statistics.

It is possible to specify a value to get a time per iteration or per entity. If use_elapsed_time is true, it uses clock time; otherwise, it uses CPU time.

dumpTimeAndMemoryUsage()

virtual void Arcane::ITimeStats::dumpTimeAndMemoryUsage ( IParallelMng * pm )

pure virtual

Displays the current date and memory consumption.

This operation is collective on pm.

This operation displays the memory consumed for the current subdomain as well as the min and max for all subdomains.

elapsedTime() [1/2]

virtual Real Arcane::ITimeStats::elapsedTime ( eTimePhase phase )

pure virtual

Real elapsed time for phase phase.

Returns the real elapsed time (in seconds) for phase phase.

elapsedTime() [2/2]

virtual Real Arcane::ITimeStats::elapsedTime ( eTimePhase phase, const String & action )

pure virtual

Elapsed time for a phase of an action.

Returns the real elapsed time (in seconds) for phase phase of action action. The returned time includes that of the action and all of its children.

isGathering()

virtual bool Arcane::ITimeStats::isGathering ( ) const

pure virtual

Indicates if statistics are active.

Statistics are active between the call to beginGatherStats() and endGatherStats().

notifyNewIterationLoop()

virtual void Arcane::ITimeStats::notifyNewIterationLoop ( )

pure virtual

Notifies that a new iteration of the calculation loop begins.

This information is used to calculate times per iteration.
