Constructor & Destructor Documentation

MLAPI::Space::Space	(	const int	NumGlobalElements,
		const int	NumMyElements = -1
	)			[inline]

Constructor with specified number of global and local elements.

Constructs a space with linear distribution.

Parameters:

	NumGlobalElements	- (In) number of global elements.
	NumMyElements	- (In) number of local elements. If different from -1, then eithere NumGlobalElements == -1, or the sum across of processors of NumMyElements equals NumGlobalElements

MLAPI::Space::Space	(	const int	NumGlobalElements,
		const int	NumMyElements,
		const int *	MyGlobalElements
	)			[inline]

Constructor for non-linear distributions.

Parameters:

	NumGlobalElements	- (In) number of global elements. Set to -1 to compute it automatically.
	NumMyElements	- (In) number of local elements. Cannot be set to -1.
	MyGlobalElements	- (In) contains the global ID of each local node.

Note:

Global ID always starts from 0.
