distribution_1d_types Module Reference

stores a lists of integer that are local to a processor. The idea is that these integers represent objects that are distributed between the different processors. The ordering is just to make some operation more efficient, logically these lists are like sets. Some operations assume that the integers represent a range of values from 1 to a (not too big) maxval, and that an element is present just once, and only on a processor (these assumption are marked in the documentation of such operations). The concrete task for which this structure was developed was distributing atoms between the processors. More...

Detailed Description

Function/Subroutine Documentation

distribution_1d_create()

subroutine, public distribution_1d_types::distribution_1d_create	(	type(distribution_1d_type), pointer	distribution_1d,
		type(mp_para_env_type), pointer	para_env,
		logical, intent(in), optional	listbased_distribution,
		integer, dimension(:), intent(in), optional	n_el,
		integer, intent(in), optional	n_lists
	)

creates a local list

Parameters

distribution_1d	the lists to create
para_env	parallel environment to be used
listbased_distribution	if each list has its own distribution (defaults to false)
n_el	number of elements in each list (defaults to 0)
n_lists	number of lists to create (defaults to 1, or size(n_el))
