Detailed Description

Struct representing a node of the local KD tree.

This structure represents a node of the local KD tree, which organizes the data within a single MPI rank.

Member Function Documentation

◆ ext()

constexpr bool criptic::LocalNodeStruct_::ext ( ) const

inlineconstexpr

Flag if this node refers to packets on an external rank.

Returns: True if this node refers to packets on an external rank

This routine returns true if and only if the this node in the tree has children, but those children reside on another MPI rank and thus this node cannot be opened on the local rank.

◆ rank()

constexpr int criptic::LocalNodeStruct_::rank ( ) const

inlineconstexpr

Rank that owns the children of an external node.

Returns: Rank that owns the children of an external node

The results are only meaningful if called on a node for which ext() returns true. Results are undefined if called on a node for which ext() returns false.

Member Data Documentation

◆ bnd

RealBox criptic::LocalNodeStruct_::bnd

Tight bounding box for node

◆ box

RealBox criptic::LocalNodeStruct_::box

Bounding box for node

◆ cm

RealVec criptic::LocalNodeStruct_::cm

Box "center of mass" determined by packet weights

◆ count

IdxType criptic::LocalNodeStruct_::count

Number of packets in this node

◆ cov

RealTensor2 criptic::LocalNodeStruct_::cov

CR packet-weighted covariance matrix

◆ fQ

FieldQty criptic::LocalNodeStruct_::fQ[TREE_RIGIDITY_BINS]

Total contribution of packets in a node to field quantities, counting only packets above specified rigidity values

◆ lchild

IdxType criptic::LocalNodeStruct_::lchild

Index of left child

◆ order

IdxType criptic::LocalNodeStruct_::order

Order of this leaf in a breadth-first traversal of the tree; set to null for non-leaf nodes

◆ parent

IdxType criptic::LocalNodeStruct_::parent

Index of parent

◆ rchild

IdxType criptic::LocalNodeStruct_::rchild

Index of right child

◆ splitDim

int criptic::LocalNodeStruct_::splitDim

Dimension along which node splits; a value of -1 indicates the node is a leaf

◆ splitVal

Real criptic::LocalNodeStruct_::splitVal

Value at which the node splits

◆ start

IdxType criptic::LocalNodeStruct_::start

Index of first packet in the node

◆ w2Sum

Real criptic::LocalNodeStruct_::w2Sum

Sum of squares of CR packet weights

◆ wSum

Real criptic::LocalNodeStruct_::wSum

Sum of CR packet weights
