Chapter 5. Frequently Asked Questions
Q:
How can I save my configuration for threads other than kernel threads?
A:
T he command line interface can be used to add a series of operations to the startup script of any
program. Develop the series of commands for T una to run at startup, and pass it to the program
as a single command. T hreads created after the initial command will inherit the affinity and
scheduling policy of the thread that creates it. For an example of an appropriate startup script, see
Chapter 3, Using the Command Line Interface.
Q:
Can T una handle multiple sockets and multiple cores?
A:
Figure 5.1. T una window for a system with multiple sockets and cores
T una supports multiple sockets and sockets with multiple cores. If there are multiple cores on a
socket, they will often share the cache on that socket.
T he T una interface groups multiple sockets within a frame, so that operations can be done on
whole sockets or on specific cores.
