GPU and LPU Integration: Attention FFN Disaggregation (AFD) - Line hint:
119
Context Before
As state-of-the-art mixture-of-expert (MoE) models grow increasingly sparse, tokens can choose experts from a larger expert pool.
Evidence
As a result, each expert receives fewer tokens, leading to lower utilization.
Context After
This motivates attention and FFN disaggregation. If a GPU only performs attention operations, its HBM capacity can be fully allocated to KV cache, increasing the total number of tokens it can process, which then increases the tokens each expert processes on average.
② Atomic Claim
因此,每個 expert 分到的 token 變少,導致 utilization 降低。
