Priority-Based Scheduling in LLM Inference
Priority-based scheduling is a general strategy for managing LLM inference by allocating system resources according to the designated importance of certain requests or computational steps. This approach aligns resource usage with specific performance goals. For instance, decoding steps can be prioritized to minimize token generation latency for individual requests, whereas prefilling steps can be prioritized to maximize overall system throughput in batch-processing scenarios.

LLM Inference Scheduling Strategy
An LLM inference server is processing a batch of three long-running requests. In the middle of this process, after several computational steps have already been completed for the initial batch, a new, short request arrives. How would a system implementing continuous batching most likely handle this new request in the next computational step?
An LLM inference system is designed to maximize hardware utilization. Which of the following operational descriptions best illustrates the core principle of continuous batching, distinguishing it from a static batching approach?

An AI company operates a service that uses a large language model to summarize vast archives of legal documents. The primary business goal is to maximize the total number of documents summarized each day. The system receives a constant stream of new summarization requests. Given this primary goal, which scheduling approach for managing inference tasks would be most effective?
