Tasks have different properties and require-ments in terms of time, e.g., WCETs, periods, and deadlines. Several tasks can be executing on the same processor, i.e., sharing the same CPU.
An important issue is to determine whether all tasks can execute as planned during peak-load.
By enforcing some task model and calculating the total task utilization in the system (e.g., the total utilization of the CPU by all tasks in the system’s task set),
or the response time of all tasks in the worst-case scenarios (at peak-load), it can be determined if they will fulfill the requirement of completing their executions within their deadlines. Examples of this are given in Section ..
