pthreads defines a set of C programming language types, functions and constants. It is implemented with a pthread.h header and a thread library. There are around 100 threads procedures, all prefixed pthread_ and they can be categorized into five groups: Thread management – creating, joining threads etc. Mutexes; Condition variables
GNU Pth (Portable Threads) is a POSIX/ANSI-C based user space thread library for UNIX platforms that provides priority-based scheduling for multithreading applications. GNU Pth targets for a high degree of portability.
A concurrent programming language is defined as one which uses the concept of simultaneously executing processes or threads of execution as a means of structuring a program. A parallel language is able to express programs that are executable on more than one processor.
Dispatch Sources are objects that allow the client to register blocks or functions to execute asynchronously upon system events, such as a socket or file descriptor being ready for reading or writing, or a POSIX signal. Dispatch Groups are objects that allow several tasks to be grouped for later joining. Tasks can be added to a queue as a ...
A process with two threads of execution, running on one processor Program vs. Process vs. Thread Scheduling, Preemption, Context Switching. In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. [1]
A sync statement indicates that execution of the current function cannot proceed until all previously spawned function calls have completed. This is an example of a barrier method. (In Cilk Plus, the keywords are spelled _Cilk_spawn and _Cilk_sync , or cilk_spawn and cilk_sync if the Cilk Plus headers are included.)

In computer science, a semaphore is a variable or abstract data type used to control access to a common resource by multiple threads and avoid critical section problems in a concurrent system such as a multitasking operating system.
