Collaboration diagram for gs_crystal_plan::gs_crystal_plan_t:

Public Member Functions
procedure, pass(this)	init (this, send_pe, recv_pe, send_dof, recv_dof)
	Work out the routing plan for a gather-scatter schedule.

procedure, pass(this)	free (this)
	Release the routing plan.

Public Attributes
type(gs_crystal_stage_t), dimension(:), allocatable	stage
	The active stages, in order. Stages that neither send nor receive leave the buffer untouched and are not represented.

integer	nstage = 0
	Number of active stages.

integer	nwrk = 0
	Words each working buffer column must hold.

integer	nsmax = 0
	Words the send buffer must hold.

integer	ntotal = 0
	Words packed out of the shared vector.

integer	nfinal = 0
	Words delivered to this rank.

integer	final_sel = 1
	Buffer column holding the delivered words.

integer, dimension(:), allocatable	pack_keep_dof
	1-based indices into the shared vector of the words that stay local over the first stage, in the order they take in the working buffer

integer, dimension(:), allocatable	pack_send_dof
	1-based indices into the shared vector of the words sent by the first stage, in the order they take in the send buffer

integer, dimension(:), allocatable	unpack_dof
	1-based indices into the shared vector that the delivered words reduce into, in the order the words arrive

integer, dimension(:), allocatable	final_off
	Offsets into unpack_dof of each delivered record, 0-based.

integer, dimension(:), allocatable	final_len
	Lengths of each delivered record.

integer	nfinal_rec = 0
	Number of delivered records.

Member Function/Subroutine Documentation

◆ free()

procedure, pass(this) gs_crystal_plan::gs_crystal_plan_t::free ( class(gs_crystal_plan_t), intent(inout) this )

Definition at line 152 of file gs_crystal_plan.f90.

◆ init()

procedure, pass(this) gs_crystal_plan::gs_crystal_plan_t::init	(	class(gs_crystal_plan_t), intent(inout)	this,
		integer, dimension(:), intent(in)	send_pe,
		integer, dimension(:), intent(in)	recv_pe,
		type(stack_i4_t), dimension(0:), intent(inout)	send_dof,
		type(stack_i4_t), dimension(0:), intent(inout)	recv_dof
	)

Runs the recursive bisection of the crystal router over record metadata alone – three integers per slab rather than the payload – so the partner ranks, word counts and index lists of every stage are known before a single gs operation runs.

Parameters

send_pe	ranks this process sends to
recv_pe	ranks this process receives from
send_dof	per-rank lists of shared dofs to send
recv_dof	per-rank lists of shared dofs to reduce into

Note: Collective over NEKO_COMM, as the bisection is.
