IN	type	type of the data map to be created (integer)
IN	global	global size of data array (integer)
IN	desc	detailed description of the data map to be created (array of integer)
IN	desctype	index type of datamap description array
IN	count	size of the description array (integer)
IN	flags	flags describing the data map to be created (integer)
OUT	datamap	new data map (handle)

C syntax:

int LIP_Datamap_create(int type, int global, void *desc, LIP_Indextype desctype, int count, int flags, LIP_Datamap *datamap)

Java syntax:
Class Datamap:

public Datamap(DataDistribution distrib, int count, int flags)
public Datamap()

LIP_DATAMAP_CREATE creates a datamap object which describes how a data array is partitioned among processors. The argument pair: (type, desc) can have the following values (which correspond to the data mappings usually used in data-parallel languages):

• (LIP_BLOCK, {local data size }),
• (LIP_BLOCK_N; { local data size of node 0, ..., local data size of node N }), not supported in version 1.0
• (LIP_CYCLIC, {}) not supported in version 1.0,
• (LIP_INDIRECT, {local data size}).

Valid flags values are: NULL or LIP_OOC.

• When LIP_OOC flag is set, the translation table is stored on disk.
