Function Documentation

int CheckI	(	const int	n,
		const int	x[]
	)

Checks whether the entries of a global integer vector are consistent over all processors. If not then a message with the approprate indices and values is displayed.

Parameters

[in]	n	number of elements of vector x (of my process)
[in]	x	local vector (double) on my process

Returns

0/-1 consistent or not

void DebugD	(	const int	n,
		const double	x[]
	)

Reads a integer number with the rank of a process from the terminal and writes the elements of vector x of this process onto the terminal. This will be repeated while rank number is valid, i.e., -1 stops the loop.

Parameters

[in]	n	number of elements of vector x (of my process)
[in]	x	local vector (double) on my process

void DebugI	(	const int	n,
		const int	x[]
	)

int ReadIn

(

)

Reads one integer from the terminal and broadcasts it to all processes.

Returns

a number read by root process 0 which is broadcasted to all processes
