Adding New Requests in Continuous Batching
In continuous batching, the scheduler can dynamically incorporate new user requests into the active batch between processing iterations. This action is conditional on the inference engine possessing sufficient available capacity to manage the additional workload. This allows the system to maintain high utilization by promptly integrating incoming tasks without waiting for the entire current batch to complete.

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.

Dynamic Request Scheduling Scenario
An inference engine using a continuous batching strategy is actively processing a set of user requests. In the brief interval between two processing iterations, the scheduler successfully incorporates a newly arrived request into the active batch. What is the most critical condition that must have been met for the scheduler to make this decision?
In a system using continuous batching, a new user request that arrives while an existing batch is being processed must wait until all requests in that current batch are fully completed before it can be considered for processing.
