Detailed Description

A timer class that starts when constructed and stops when the destructor is called.

Termination upon destruction lets this timer behave correctly even if scope is exited because of an std::exception.

NOTE: It is critical that this class only be used to time functions that are called only within the main program and not at pre-program setup or post-program teardown!

Note:

Teuchos::TimeMonitor uses the Teuchos::Time class internally.

Examples:

TimeMonitor/cxx_main.cpp.

Constructor & Destructor Documentation

Teuchos::TimeMonitor::TimeMonitor (  Time &  timer, bool  reset = false )  [inline]

Constructor starts timer.

Teuchos::TimeMonitor::~TimeMonitor (   )  [inline]

Destructor causes timer to stop.

Member Function Documentation

Teuchos::RCP<Time> Teuchos::TimeMonitor::getNewTimer (  const std::string &  name  )  [inline, static]

Wrapping of getNewCounter() for backwards compatibiity with old code. Examples: TimeMonitor/cxx_main.cpp.

void Teuchos::TimeMonitor::zeroOutTimers (   )  [static]

Reset the global timers to zero. Preconditions: None of the timers must currently be running!

void Teuchos::TimeMonitor::summarize (  std::ostream &  out = std::cout, const bool  alwaysWriteLocal = false, const bool  writeGlobalStats = true, const bool  writeZeroTimers = true )  [static]

Print summary statistics for a group of timers. Timings are gathered from all processors Note: This method must be called by all processors Examples: TimeMonitor/cxx_main.cpp.
