Example of Reusing a Completed Slot in Continuous Batching (Iteration 6)
This diagram illustrates the sixth iteration in a continuous batching process, which occurs after request x₂ has completed. New requests, x₄ and x₅, arrive in the system. The scheduler dynamically adjusts the batch by using the resources freed up by the completed request x₂ to accommodate the new request x₄. In a single computational step, the system concurrently performs the prefilling phase for x₄ while also executing a single decoding step for the ongoing requests x₁ and x₃. This highlights a key efficiency of continuous batching: the immediate reuse of resources to interleave the processing of new and existing requests, thereby maximizing throughput.

Example of Reusing a Completed Slot in Continuous Batching (Iteration 6)
An inference engine is using a dynamic batching strategy to process three text generation requests simultaneously: Request A, Request B, and Request C. After a single, parallel decoding step is applied to all three, the system determines that Request B has finished generating its full output, while Requests A and C still require more steps. What is the most significant, immediate consequence of Request B's completion for the system's operation in the very next processing step?
An LLM inference engine is processing a batch of multiple, independent requests using a dynamic scheduling approach. One of these requests is about to finish. Arrange the following events in the correct chronological order, starting from the computational step that generates the final piece of output.

An inference system is processing a batch of requests using a dynamic scheduling method. At a specific moment, one request (Request A) completes its generation. The system still has two ongoing requests (Request B and Request C) that require further processing. At the same time, a new request (Request D) arrives. Given this state, which of the following actions by the system's scheduler represents the most efficient use of computational resources in the very next step?
