Module multi_tile 

Multi-tile / multi-device dispatch for Intel Level Zero GPUs.

Intel Xe-HPC (Ponte Vecchio) and other large-tile Intel GPUs expose individual compute tiles as Level Zero “sub-devices”. This module discovers those sub-devices and distributes matrix work across them.

Overview

LevelZeroDevice (root)
  ├── Tile 0  (sub-device handle)
  ├── Tile 1
  └── Tile N-1

When sub-devices are not available (older GPUs, consumer Xe Arc), the MultiTileDispatcher transparently falls back to single-device dispatch.

Structs

MultiTileConfig

Configuration for the multi-tile dispatcher.

MultiTileDispatcher

Enumerates Level Zero sub-devices and partitions matrix work across tiles.

SubDeviceInfo

Metadata for a single Level Zero sub-device (compute tile).

TileWorkSlice

Work assignment for one tile during a GEMM dispatch.

Enums

WorkDistribution

How to partition a matrix operation across multiple compute tiles.
