'chrt' and 'taskset'

The Linux scheduler utilities take advantage of the scheduler family of syscalls that Linux implements across various kernels. These system calls implement interfaces for scheduler-related parameters such as CPU affinity and real-time attributes. Standard utilities do not support these interfaces, thus 'schedutils.' 'Schedutils' includes 'chrt' and 'taskset'. Together with nice and renice (not included), they allow full control of process scheduling parameters. 'taskset' manipulates task CPU affinity; 'chrt' manipulates scheduling priority and policy. 'irqset' and 'lsrt' are no longer included.
