Detailed Description

Provides distributed log functionality.

When the file is written each process data is collected by rank 0 who writes the data to a single file in rank order.

The log works as an event stack. EventStart pushes the event identifier and its start time onto the stack. EventEnd pops the most recent event time and identifier computes the elapsed time and adds an entry to the log recording the event, it's start and end times, and its elapsed time. EndEventSynch includes a barrier before the measurement.

The log class implements the singleton pattern so that it may be shared across class boundaries. If the log instance doesn't exist then one is created. It will be automatically destroyed at exit by the signleton destructor. It can be destroyed explicitly by calling DeleteGlobalInstance.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

virtual void vtkParallelTimer::SetWriterRank ( int )

virtual

Set the rank who writes.

virtual int vtkParallelTimer::GetWriterRank ( )

virtual

Set the rank who writes.

virtual void vtkParallelTimer::SetFileName ( const char * )

virtual

Set the filename that is used during write when the object is used as a singleton.

If nothing is set the default is ROOT_RANKS_PID.log

virtual char* vtkParallelTimer::GetFileName ( )

virtual

Set the filename that is used during write when the object is used as a singleton.

If nothing is set the default is ROOT_RANKS_PID.log
