Function Documentation

void draw_bar	(	double	x,
		double	y,
		T	max_load,
		T	min_load,
		double	avg
	)

Draws color legend to figure out load imbalance.

Parameters:

	x	Coordinate -- distance from top.
	y	Coordinate -- distance from left.
	max	Maximum value in the input space. Maps to complete red color (255,0,0).
	min	Minimum value in the input space. Maps to complete blue color (0,0,255).
	avg	Perfect load imbalance value. Maps to complete white color (255,255,255).

void draw_footer	(	double	x,
		double	y,
		char *	instName,
		char *	cutName,
		int	proc
	)

Prints instance and cut filename, and processor count as text.

Parameters:

	x	Coordinate -- distance from top.
	y	Coordinate -- distance from left.
	instName	Instance file name.
	cutName	Cuts file name.
	proc	Processor count.

void draw_rectangle	(	double	x,
		double	y,
		double	w,
		double	h,
		std::string	color_in,
		double	stroke_width = 0.1,
		std::string	color_out = "0,0,0"
	)

Draws a single rectangle at a specified location, dimensions and color.

Parameters:

	x	Coordinate -- distance from top.
	y	Coordinate -- distance from left.
	w	Rectangle width.
	h	Rectangle height.
	color_in	Input color string in format "R,G,B" (This is the output of getColor() function)
	stroke_width	Stroke width in SVG. This looks like a frame around the rectangle. (0.1 by default)
	color_out	Stroke color.

void draw_rectangles	(	RectList< T, Pr > &	rl,
		const Pr &	pr,
		int	numProc,
		char *	inst,
		char *	cuts,
		T	min_load,
		T	max_load,
		bool	legend
	)

Draws a complete SVG image of Load imbalance chart with legends and other information.

Parameters:

	rl	Input rectangle list.
	pr	Input prefix sum array.
	numProc	Number of processors.
	inst	Instance file name.
	cuts	Cut file name.
	min_load	Minimum value in the input space. Maps to complete blue color (0,0,255).
	max_load	Maximum value in the input space. Maps to complete red color (255,0,0).
	legend	Set to true to draw a color legend.

void draw_text	(	double	x,
		double	y,
		std::string	text,
		double	font_size,
		std::string	anchor = "bottom",
		double	angle = 0
	)

Prints text on SVG.

Parameters:

	x	Coordinate -- distance from top.
	y	Coordinate -- distance from left.
	text	Text to print.
	font_size	Font size in SVG.
	anchor	Anchor in SVG. (bottom by default)
	angle	To rotate text in SVG. (0 by default)

std::string get_svg_header

(

)

Prints standard SVG header to the SVG file.

Returns:

SVG header that goes to the beginning of the .svg file.

std::string getColor	(	T	max,
		T	min,
		T	val,
		double	perfect
	)

Returns string in format "R,G,B" where R:Red, G:Green, B:Blue is the color code.

Returns string in format "R,G,B" where R:Red, G:Green, B:Blue is the color code. This is used to draw rectangles in SVG.

Parameters:

	max	maximum value in the input space. Maps to complete red color (255,0,0).
	min	minimum value in the input space. Maps to complete blue color (0,0,255).
	val	input value to be converted to color.
	perfect	perdect load inbalance value (that will map to white color).

Returns:

Color string in "R,G,B" format.

int main	(	int	argc,
		char *	argv[]
	)

Synopsis: spart_2d_visual <instance> <nbproc> <cut_file> instance: Begins with a line with number of tasks in X and Y dimension. The rest of the lines contain 1 task load per line. nbproc: number of processors cutfile: List of rectangle cuts

Parameters:

	argc
	argv

Returns:

Given 2d instance and cut rectangles, outputs SVG image of load heat map or partition scheme
