Provides interface for changing scheduler and IRQ tunables, at whole CPU and at per thread/IRQ level. Allows isolating CPUs for use by a specific application and moving threads and interrupts to a CPU by just dragging and dropping them. Operations can be done on CPU sockets, understanding CPU topology. Can be used as a command line utility without requiring the GUI libraries to be installed.
