Function Documentation

SetLoad() [1/2]

void SetLoad	(	Tessellation &	tproc,
		vector< Vector2D > &	points,
		OuterBoundary const &	outer,
		int	Niter = 100,
		double	speed = 0.04,
		int	mode = 2,
		bool	Rmin = false
	)

Corrects the load between processors based on number of cells per processor.

Parameters

tproc	The tessellation of the processors
points	The local cell points of the current rank (the points for this current cpu), may be redistributed among other cpus
outer	The geometric boundary conditions
Niter	The number of correction iterations to use
speed	How fast to make the correction each iteration in units of cpu cell size
mode	The operating mode, 1=Hybrid, 2=Pressure based, 3= Density based
Rmin	Optional, sets a minimum radius for a cpu point to be at. This is sometimes needed in order to prevent cpus with zero points.

SetLoad() [2/2]

void SetLoad	(	Tessellation &	tproc,
		vector< Vector2D > &	points,
		OuterBoundary const &	outer,
		double	TargetLoad,
		double	speed = 0.04,
		int	mode = 2,
		bool	Rmin = false
	)

Corrects the load between processors based on number of cells per processor, continues until target load is reached.

Parameters

tproc	The tessellation of the processors
points	The local cell points of the current rank (the points for this current cpu), may be redistributed among other cpus
outer	The geometric boundary conditions
TargetLoad	The target load balance, must be higher than 1, recommened to be 1.5
speed	How fast to make the correction each iteration in units of cpu cell size
mode	The operating mode, 1=Hybrid, 2=Pressure based, 3= Density based
Rmin	Optional, sets a minimum radius for a cpu point to be at. This is sometimes needed in order to prevent cpus with zero points.
