Chapter 6: Controlling CPU Workload

This chapter describes how to use IRIX kernel features to make the execution of a real-time program predictable. Each of these features works in some way to dedicate hardware to your program's use, or to reduce the influence of unplanned interrupts on it. The main topics covered are:

"Using Priorities and Scheduling Queues" covers scheduling concepts, tells how to set nondegrading priorities, and explains affinity scheduling, gang scheduling, and deadline scheduling.
"Using Processor Sets" describes how to define sets of CPUs and how to assign them to specific kinds of work.
"Minimizing Overhead Work" discusses how to remove all unnecessary interrupts and overhead work from the CPUs that you want to use for real-time programs.
"Minimizing Interrupt Response Time" discusses the components of interrupt response time and how to minimize them.
