Wavel: A Fast and Efficient Compilation System for Wafer-Scale Accelerators

Wafer-scale accelerators offer a new scaling point for AI infrastructure, but they also create a new compilation regime: communication cost varies sharply with location, and the space of possible placements and execution schedules is enormous. Existing GPU, distributed, and vendor compilation systems largely retain a sharding-oriented view and therefore fail to fully leverage these emerging accelerators, leaving the dominant physical scheduling decisions unresolved.
