Classes
class	sdfg::tiles::AxisSchedule
	Target-neutral cooperation facts derived from one loop's schedule. More...
class	sdfg::tiles::TileAxis
	One enclosing parallel loop of a tile: its schedule facts plus the tile-role (Private when its indvar addresses the tile base, Cooperative otherwise). More...
class	sdfg::tiles::Tile
	A container's staged region: source maps a tile coordinate to the global element, axes is the thread/value partition, and the read/write flags give the copy direction. More...

Enumerations
enum class	sdfg::tiles::Level { sdfg::tiles::Device , sdfg::tiles::Group , sdfg::tiles::Subgroup }
	Cooperation scope of a parallel axis, coarsest to finest — target-neutral tiers (OpenCL/SYCL vocabulary). More...
enum class	sdfg::tiles::Space { sdfg::tiles::Global , sdfg::tiles::Shared , sdfg::tiles::Register }
	Memory that backs cooperation at a level: Device/CPU -> Global (atomics/heap), Group -> Shared, Subgroup/none -> Register. More...
enum class	sdfg::tiles::Role { sdfg::tiles::Private , sdfg::tiles::Cooperative }
	Whether the tile is per-iteration-private or shared across a parallel axis. More...

Detailed Description

Schedule-aware tile vocabulary: a Tile is a Layout (geometry from MemoryLayoutAnalysis) partitioned over the enclosing parallel loop nest (TileAxis) and classified into a required memory Space.

Pipeline: AxisSchedule::classify → TileAxis::enclosing → Tile → Tile::placement (a LocalityPlan) → storage Space.
