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
The POSIX pthreads APIs in PX5 RTOS offer support for various mechanisms, such as signals, condition variables, semaphore, mutex, and message queues. Furthermore, extensions like event flags, fast queues, tick timers, and memory management are also included. PX5 RTOS maintains a small footprint and exhibits rapid scalability.
Such languages provide synchronization constructs whose behavior is defined by a parallel execution model. 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.
[4]: 226 This is the simplest of the three threading models (1:1, N:1, and M:N). [4]: 215–216 New threads are created with the clone() system call called through the NPTL library. NPTL relies on kernel support for futexes to more efficiently implement user-space locks. [4]: 182
Often also called a replicated workers or worker-crew model, [1] a thread pool maintains multiple threads waiting for tasks to be allocated for concurrent execution by the supervising program. By maintaining a pool of threads, the model increases performance and avoids latency in execution due to frequent creation and destruction of threads for ...
This tool is implemented as a set of functions on the Emacs editor. All the activities related to program parallelization, such as selecting a target portion of the program, invoking an assistance command, and modifying the program based on the assistance information shown by the tool, can be handled in the source program editor environment.

A large language model (LLM) is a type of machine learning model designed for natural language processing tasks such as language generation. LLMs are language models with many parameters, and are trained with self-supervised learning on a vast amount of text. This page lists notable large language models.
The various languages and libraries offering a PGAS memory model differ widely in other details, such as the base programming language and the mechanisms used to express parallelism. Many PGAS systems combine the advantages of a SPMD programming style for distributed memory systems (as employed by MPI ) with the data referencing semantics of ...
