eve deterministic latency (reduce task switching) and increase performance by ensuring application code and data remains local to the core cache. Processor binding can be done using the Linux <taskset> command which is used for setting or retrieving a process' CPU affinity. Input parameters are the Linux process ID (pid) and a mask that defines the allowed processor cores this process can execute on. More advanced features are supported through the cpuset concept. Note that binding applications implies that other applications are no longer capable of running on these cores. This may reduce performance for lower-priority applications that have fewer core resources available to them. Optimized implementations tune performance further by disabling os services that consume unnecessary behavior or can create unex- pected system behavior, or potentially all os services besides the explicitly needed ones. This includes background applications such as memory scrubbers (e.g., Patrol Scrub). Scheduler policies define which (out of multiple available) processes is run on the core. There are several possible Linux scheduler priorities including: SCHED_OTHER is the default scheduling policy for processes that do not have any priority/real-time requirements. SCHED_FIFO schedules processes until they relinquish control back to the scheduler and can only be interrupted by other, higher-priority processes. Chapter 5 System software SCHED_RR is like SCHED_FIFO but each process is allocated for a certain portion of physical time (its quantum) before it is placed at the end of the scheduling list for a given priority. Process priority can be set in software through the <sched_setscheduler()> API or through the Linux command line with <chrt> Some processors support a Turbo mode of operation given thermal and DC power headroom-potentially enabled by Dynamic Voltage and Frequency Scaling. For telecommunications-grade systems with high reliability and performance predictability requirements, this mode is often disabled. On the opposite
