propMappSubtreeOn1P()

static void propMappSubtreeOn1P ( const propmap_t *  pmptr, pastix_int_t  rootnum, pastix_int_t  fcandnum, pastix_int_t  lcandnum, pastix_int_t  cluster  )

inlinestatic

Set the given candidates to all the subtree w/o conditions.

Parameters

[in]	pmptr	Pointer to the parameters of the proportional mapping algorithm.
[in]	rootnum	Index of the root of the subtree to be given to [fcandnum,lcandnum]
[in]	fcandnum	Rank of the first candidate attributed to this subtree.
[in]	lcandnum	Rank of the last candidate attributed to this subtree.
[in]	cluster	The cluster value for the subtree.

propMappSubtree()

static void propMappSubtree ( const propmap_t *  pmptr, pastix_int_t  rootnum, pastix_int_t  fcandnum, pastix_int_t  lcandnum, pastix_int_t  cluster, double *  cost_remain  )

inlinestatic

Apply the proportional mapping algorithm to a subtree.

Parameters

[in]	pmptr	Pointer to the parameters of the proportional mapping algorithm.
[in]	rootnum	Index of the root of the subtree to process.
[in]	fcandnum	Rank of the first candidate attributed to this subtree.
[in]	lcandnum	Rank of the last candidate attributed to this subtree.
[in]	cluster	The cluster value for the subtree.
[in,out]	cost_remain	Array of size (lcandnum-fcandnum+1). Stores the remaining idle time of each candidate to balance the load among them. On exit, the cost is updated with the affected subtrees.
