Parallel computing - Wikipedia
https://en.wikipedia.org/wiki/Parallel_computing- Parallel computing is a type of computation in which many calculations or processes are carried out simultaneously. Large problems can often be divided into smaller ones, which can then be solved at the same time. There are several different forms of parallel computing: bit-level, instruction-level, data, and task parallelism.

From Simple English Wikipedia, the free encyclopedia Parallel computing is a form of computation in which many instructions are carried out simultaneously (termed "in parallel"), depending on the theory that large problems can often be divided into smaller ones, and then solved concurrently ("in parallel").

- https://en.wikipedia.org/wiki/Parallel_programming_model
In computing, a parallel programming model is an abstraction of parallel computer architecture, with which it is convenient to express algorithms and their composition in programs. The value of a programming model can be judged on its generality: how well a range of different problems can be expressed for a variety of different architectures, and its performance: how efficiently the compiled programs can execute. The implementation of a parallel programming model can tak…

From Wikipedia, the free encyclopedia In parallel computing, granularity (or grain size) of a task is a measure of the amount of work (or computation) which is performed by that task. Another definition of granularity takes into account the communication overhead between multiple processors or processing elements.

From Wikipedia, the free encyclopedia For other uses, see Massively parallel (disambiguation). Massively parallel is the term for using a large number of computer processors (or separate computers) to simultaneously perform a set of coordinated computations in parallel. GPUs are massively parallel architecture with tens of thousands of threads.

- https://en.wikipedia.org/wiki/Message_Passing_Interface
MPI is a communication protocol for programming parallel computers. Both point-to-point and collective communication are supported. MPI "is a message-passing application programmer interface, together with protocol and semantic specifications for how its features must behave in any implementation."
