Function Documentation

coeftabAlloc()

void coeftabAlloc

(

pastix_data_t *

pastix_data

)

Allocates the entire coeftab matrix with a single allocation.

The different cblk coeftabs are assigned inside the allocation, each one with their right size.

Parameters

[in,out]

pastix_data

The pastix_data structure that describes the solver instance. On exit, the internal coeftab matrix is allocated.

pcoeftabInit()

void pcoeftabInit	(	isched_thread_t *	ctx,
		void *	args
	)

Internal routine called by each static thread to Initialize the solver matrix structure.

This routine is the routine called by each thread in the static scheduler and launched by the coeftabinit().

Parameters

[in,out]	ctx	The internal scheduler context
[in]	args	The data structure specific to the function cpucblk_zinit()

Definition at line 161 of file coeftab.c.

pcoeftabComp()

static void pcoeftabComp ( isched_thread_t *  ctx, void *  args  )

static

Internal routine called by each static thread to Initialize the solver matrix structure.

This routine is the routine called by each thread in the static scheduler and launched by the coeftabCompress().

Parameters

[in,out]	ctx	The internal scheduler context
[in]	args	The data structure specific to the function cpucblk_zcompress()
