Part II. Application Architecture
The Red Hat Enterprise Linux for Real Time kernel provides a number of constructs that are designed to help software developers build an application that performs to the highest possible standards. This section discusses those features and how to use them.
Throughout this and the next sections, instructions are given for tuning the Red Hat Enterprise Linux for Real Time kernel directly. Most changes can also be performed using a tool called Tuna. It has a graphical interface, or can be run through the command shell.
Tuna can be used to change attributes of threads and interrupts, such as scheduling policy, scheduler priority and processor affinity. It is designed to be used on a running system, and changes take place immediately. This allows any application-specific measurement tools to see and analyze system performance immediately after the changes have been made.
