Top Stories
Accelerator Architecture: Fusion-Aware Mapper (MIT)
One-sentence take: MIT researchers introduced the Fast and Fusiest Mapper (FFM), an optimal tool for finding fused mappings on tensor algebra accelerators, dramatically reducing latency and energy by pruning suboptimal search spaces.
What happened: Researchers from MIT published a paper on ‘Fast and Fusiest: An Optimal Fusion-Aware Mapper for Accelerator Modeling and Evaluation,’ introducing FFM, which efficiently navigates exponential mapspaces for AI accelerators by pruning suboptimal partial mappings while guaranteeing optimal fused mappings that keep data on-chip to minimize DRAM accesses.
Why it matters: FFM is over 1000x faster than prior mappers for Transformers, yielding 1.3-37x lower latency, enabling faster AI hardware design evaluation, reduced operational costs, and enhanced efficiency for complex models in edge AI and real-time applications.
- FFM runtime scales linearly despite exponential mapspace growth
- Fusion keeps data on-chip between steps to cut energy and latency
- Superior to prior art by greater than 1000x speed and better mapping quality
