Witness fragment for aggregation

Compact representation of local cut/partition information that can be merged across tiles.

Fields

seed: TileVertexId

Seed vertex for this fragment

boundary_size: u16

Boundary size (cut edges crossing fragment)

cardinality: u16

Cardinality (vertices in fragment)

hash: u16

Fragment hash for consistency checking

local_min_cut: u16

Local minimum cut value (fixed-point)

component: u16

Component ID this fragment belongs to

_reserved: u16

Reserved padding
