HomeMoonshot AI and Tsinghua University Propose PrfaaS Architecture for Data Centers
As large language models (LLMs) demand more computational power during reasoning, conventional service architectures encounter bottlenecks. Moonshot AI, in collaboration with a research team from Tsinghua University, has introduced a novel architecture called Pre-filling as a Service (PrfaaS), aimed at overcoming the constraints of data centers and computing resources in LLM services.
The reasoning process of large language models is generally split into two phases: pre-filling and decoding. Pre-filling is computationally intensive, where the model processes input and creates a key-value cache (KVCache). Decoding is memory bandwidth-intensive, generating outputs sequentially. Traditional setups require both stages to occur within the same data center, leading to constraints in computation and bandwidth.
PrfaaS enables efficient cross-data-center service by offloading pre-filling tasks to dedicated high-compute clusters, using a standard Ethernet network to transfer the generated KVCache to local decoding clusters. Research indicates that this architecture boosts processing performance, achieving a 54% increase in service throughput over traditional models. Real-world case studies also show lower latency and higher efficiency.
The PrfaaS architecture decouples the three main subsystems—computing, networking, and storage—managing each independently. A precise routing mechanism ensures efficient transmission of long requests, preventing congestion from uneven resource allocation seen in traditional approaches. Additionally, a dual-timescale scheduling mechanism adapts to varying traffic patterns, further optimizing resource usage.
As the demand for cross-data-center reasoning grows and new hardware continues to emerge, PrfaaS offers a promising solution for future AI applications.
