Detailed Description

compute uniform partitioning of n-dimensional rectilinear

Function/Subroutine Documentation

uniform_decomposition_1d()

subroutine ppm_uniform_partition::uniform_decomposition_1d ( type(extent), intent(in) set_interval, integer, intent(in) nparts, type(extent), dimension(nparts), intent(out) parts, logical, intent(in), optional symmetric )

private

divide integer set interval into evenly sized sub-intervals forming a partition

Parameters

set_interval	interval to partition
nparts	number of parts to compute
parts	nparts sub-intervals
symmetric	if .true. partitions(i) will be same-size as partitions(nparts-i+1)

uniform_decomposition_nd()

subroutine ppm_uniform_partition::uniform_decomposition_nd ( type(block_decomposition), dimension(:), intent(out) pgrid, type(extent), dimension(:), intent(in) rect, integer, dimension(:), intent(in) nparts, logical, dimension(:), intent(in), optional symmetric )

private

Compute uniform divisions of rectilinear structure.

Parameters

pgrid	same dimension as rect and nparts, holds list of partition extents
rect	intervals for indices of rectilinear to partition
nparts	number of parts to compute in each dimension
symmetric	symmetry requirements for each dimension

uniform_partition()

elemental type(extent) function, public ppm_uniform_partition::uniform_partition	(	type(extent), intent(in)	set_interval,
		integer, intent(in)	nparts,
		integer, intent(in)	part_idx,
		logical, intent(in), optional	symmetric )

compute nth part of integer set interval

The interval is divided into roughly same sized sub-intervals forming a uniform partition.

Parameters

set_interval	global domain
nparts	number of parts to decompose into
part_idx	number of sub-interval to compute
symmetric	if .true. ensure that SIZE(uniform_partition(i)) == SIZE(uniform_partition(nparts - i + 1))

Returns

part range corresponding to part_idx
