Functions
int	chameleon_desc_init_base (CHAM_desc_t *desc, int myrank, const char *name, const CHAM_desc_storage_t *storage, const CHAM_desc_layout_t *layout)
	Initialize descriptor invariants shared by all descriptor creation paths.
int	chameleon_ipiv_init (CHAM_ipiv_t *ipiv, cham_side_t side, int mb, int m, int withidx, int max_m, int max_mt, int p, int np, void *data, blkrankof_ipiv_fct_t get_rankof)
	Internal function to create tiled descriptor associated to a pivot array.
void	chameleon_ipiv_destroy (CHAM_ipiv_t *ipiv)
	Internal function to destroy a tiled descriptor associated to a pivot array.
int	CHAMELEON_Ipiv_Create (CHAM_ipiv_t **ipivptr, cham_side_t side, int mb, int m, int p, int np, void *data)
	Create a tiled ipiv descriptor associated to a given matrix.
int	CHAMELEON_Ipiv_Destroy (CHAM_ipiv_t **ipivptr)
	Destroys an ipiv tile descriptor.
int	CHAMELEON_Ipiv_Flush (const CHAM_ipiv_t *ipiv, RUNTIME_sequence_t *sequence)
	Flushes the data in the sequence when they won't be reused. This calls cleans up the distributed communication caches, and transfer the data back to the CPU.
int	CHAMELEON_Ipiv_Gather (const CHAM_ipiv_t *ipivdesc, int *ipiv, int root)
	Gathers an IPIV tile descriptor in a single vector on the given root node.
int	chameleon_pivot_init (CHAM_desc_pivot_t *pivot, const CHAM_desc_t *desc)
	Internal function to create tiled descriptor associated to a pivot.
int	chameleon_pivot_destroy_submit (CHAM_desc_pivot_t *pivot, RUNTIME_sequence_t *sequence)
	Asynchronously destroy a tiled descriptor associated to a pivot array.
int	chameleon_pivot_destroy (CHAM_desc_pivot_t *pivot)
	Destroy a tiled descriptor associated to a pivot array.
