For just the main thread (or the thread of whatever PID you give). You need to set the PID of each thread individually. The "everything appears as a single PID" is just an elaborate parlor trick. Wool pulled over your eyes. > Can I used the thread IDs from /proc/<pid>/task/ to chrt the other > threads in my app to different priorities? You can use the PID's in /proc/<pid>/task/, yes. Or you can just set the PID of the main thread before it starts other threads, or use chrt to launch the program, or use chrt to set the PID of a shell script that starts the application: Scheduler properties are inherited.
