Function Documentation

AllocateRefinementWorkSpace()

void AllocateRefinementWorkSpace	(	ctrl_t *	ctrl,
		idx_t	nbrpoolsize
	)

This function allocates refinement-specific memory for the workspace

AllocateWorkSpace()

void AllocateWorkSpace	(	ctrl_t *	ctrl,
		graph_t *	graph
	)

This function allocates memory for the workspace

cnbrpoolGetNext()

idx_t cnbrpoolGetNext	(	ctrl_t *	ctrl,
		idx_t	nnbrs
	)

This function gets the next free index from cnbrpool

cnbrpoolReset()

void cnbrpoolReset

(

ctrl_t *

ctrl

)

This function resets the cnbrpool

FreeWorkSpace()

void FreeWorkSpace

(

ctrl_t *

ctrl

)

This function frees the workspace

ikvwspacemalloc()

ikv_t* ikvwspacemalloc	(	ctrl_t *	ctrl,
		idx_t	n
	)

This function allocate space from the core

vnbrpoolReset()

void vnbrpoolReset

(

ctrl_t *

ctrl

)

This function resets the vnbrpool

wspacemalloc()

void* wspacemalloc	(	ctrl_t *	ctrl,

	)

This function allocate space from the workspace/heap

wspacepop()

void wspacepop

(

wspacepush()

void wspacepush

(

ctrl_t *

ctrl
