About: Process Contention Scope

Process Contention Scope is one of the two basic ways of scheduling threads. Both of them being: processlocal scheduling (known as Process Contention Scope, or Unbound Threads—theMany-to-Many model) and system global scheduling (known as System Contention Scope, or Bound Threads—the One-to-One model). These scheduling classes areknown as the scheduling contention scope, and are defined only in POSIX. Processcontention scope scheduling means that all of the scheduling mechanism for thethread is local to the process—the thread's library has full control over whichthread will be scheduled on an LWP. This also implies the use of either the Many-to-One or Many-to-Many model.
