# Complexity of Uniprocessor Scheduling Analysis

- 3 Downloads

## Abstract

When designing a real-time system, a *schedulability problem* must be solved in order to show that it will meet all timing constraints at runtime. These are decision problems that, given a model of the system as input, answer whether all timing constraints will be met using a particular combination of scheduling algorithm and computer platform. Creating efficient algorithms for solving schedulability problems is a major focus of real-time systems research, but many of these problems are computationally intractable to varying degrees. Here we will review what is currently known about the computational complexity of schedulability problems for some common task models and scheduling algorithms on uniprocessors.
