Prefilling-Prioritized Strategy in Continuous Batching
The prefilling-prioritized strategy is a core characteristic of continuous batching where the scheduler adds new requests to the active batch as soon as the inference engine has available resources. By processing these new requests for prefilling as early as possible, this approach is designed to maximize system throughput. However, this prioritization comes at the cost of increased latency for ongoing requests, as the prefilling of new, long inputs can extend the overall processing time for the entire batch.

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?

Inference Scheduling Trade-offs
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?

Throughput-Latency Trade-off in Prefilling-Prioritized Continuous Batching
An inference server is managing a batch of several short, ongoing requests that are in the process of generating output. A new request with a very long input sequence arrives. The system's scheduler immediately incorporates this new request into the active batch to begin processing it, aiming to keep the hardware as busy as possible. What is the most probable consequence for the initial short requests already in the batch?
