Removing Completed Sequences in Continuous Batching
A key dynamic adjustment made by the scheduler in continuous batching is the removal of completed sequences from the active batch. Once a sequence finishes its generation, typically signaled by an end-of-sequence token, it is immediately removed. This action, performed between iterations, frees up computational resources for new or ongoing requests.

Overhead of Dynamic Batch Reorganization in Continuous Batching
An LLM inference system is processing a batch of user requests. An observer notes the following: At the start of one processing step, the active batch contains requests {A, B, C, D}. Immediately before the next processing step begins, the active batch contains requests {A, C, E}. Based on this observation, what is the most fundamental principle of this system's batch management strategy?
Inference Batch Management Scenario
An LLM inference engine processes requests in iterative cycles. Arrange the following events to show the correct sequence for a single cycle where the active batch of requests is modified.
Learn After
An inference engine is processing a group of three text generation requests simultaneously. After a few computational steps, two of the requests have finished generating their complete output, while the third, much longer request, is still in progress. To optimize overall system throughput, what is the most logical immediate next action for the engine's scheduler to take regarding this group of requests?
