This file contains the layout implementation.

Function Documentation

esdm_status esdm_layout_finalize ( esdm_instance_t * esdm )

Shutdown ESDM:

esdm_layout_t* esdm_layout_init ( esdm_instance_t * esdm )

Initializes the init component by allocating and populating the esdm_layout structure.

esdm_status esdm_layout_recommendation	(	esdm_instance_t *	esdm,
		esdm_fragment_t *	in,
		esdm_fragment_t *	out
	)

Splits pending requests into one or more requests based on performance estimates obtained from available backends.

esdm_fragment_t* esdm_layout_reconstruction	(	esdm_dataset_t *	dataset,
		esdm_dataspace_t *	subspace
	)

The layout reconstructor finds a reconstruction for subspace of a dataset.

The reconstruction should take performance considerations into account.
