The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experimental results show that ArcLight significantly surpasses the performance ceiling of mainstream frameworks, achieving up to 46% higher inference throughput.

C2weakest assumption

The assumption that cross-NUMA memory access is the dominant scalability bottleneck on many-core CPUs and that the proposed memory management and tensor parallelism will generalize without major tuning across different CPU models and workloads.

C3one line summary

ArcLight delivers up to 46% higher LLM inference throughput on many-core CPUs by addressing cross-NUMA memory access costs through efficient memory management, thread scheduling, and tensor parallelism.
