procedure, pass(this)	free (this)

Public Attributes
integer	lvl = -1
	The level id.

integer	nnodes = 0
	number of nodes on the level

type(tamg_node_t), dimension(:), allocatable	nodes
	TreeAMG tree nodes on the level.

integer	fine_lvl_dofs = 0
	Number of dofs on the level(TODO:sum of dofs on each node?)

real(kind=rp), dimension(:), allocatable	wrk_in
	Work vector for data coming into the level.

type(c_ptr)	wrk_in_d = C_NULL_PTR

real(kind=rp), dimension(:), allocatable	wrk_out
	Work vector for data leaving the level.

type(c_ptr)	wrk_out_d = C_NULL_PTR

integer, dimension(:), allocatable	map_finest2lvl

type(c_ptr)	map_finest2lvl_d = C_NULL_PTR

integer, dimension(:), allocatable	map_f2c

type(c_ptr)	map_f2c_d = C_NULL_PTR

integer, dimension(:), allocatable	agg_ptr
	Transpose of map_finest2lvl in CSR form: agg_dof(agg_ptr(c) : agg_ptr(c+1)-1) are the finest-level dofs belonging to aggregate c. Lets the flat matvec restrict as a segmented reduction over aggregates (disjoint writes) instead of an atomic scatter over dofs.

integer, dimension(:), allocatable	agg_dof

real(kind=rp), dimension(:,:), allocatable	agg_part
	Per-thread partial sums, only allocated on levels with too few aggregates to give every thread one (the coarsest level has exactly one, from aggregate_end). Shaped (ldpart, nthrds) with the leading dimension padded up to a cache line so the columns do not false share; only rows 1:nnodes carry data.
