Detailed Description

template<class T>
class MemSetter< T >

Sets large amounts of values to a constant using multiple threads.

Member Function Documentation

template<class T >

bool MemSetter< T >::doPrepare ( int nrthreads ) [inline, virtual]

Called before any doWork is called.

Reimplemented from ParallelTask.

template<class T >

bool MemSetter< T >::doWork	(	int64_t	start,
		int64_t	stop,
		int	threadid
	)			`[inline, virtual]`

The functions that does the job. The function will be called with all intervals from 0 to ParallelTask::nrIterations()-1. The function must be designed to be able to run in parallel.

Parameters:

threadid

gives an identifier (between 0 and nr of threads -1) that is unique to each call to doWork.

Implements ParallelTask.

template<class T>

int MemSetter< T >::minThreadSize ( ) const [inline, virtual]

Returns:: the minimum number of computations that effectively can be run in a separate thread. A small number will give a large overhead for when each step is quick and nrIterations is small.

Reimplemented from ParallelTask.

template<class T>

int64_t MemSetter< T >::nrIterations ( ) const [inline, virtual]

Returns:: the number of times the process should be run.

Implements ParallelTask.
