Concurrent computing is a form of computing in which programs are designed as collections of interacting computational processes that may be executed in parallel. Concurrent programs (processes or threads) can be executed on a single processor by interleaving the execution steps of each in a time-slicing way, or can be executed in parallel by assigning each computational process to one of a set of processors that may be close or distributed acros...

Concurrent computing is a form of computing in which programs are designed as collections of interacting computational processes that may be executed in parallel. Concurrent programs (processes or threads) can be executed on a single processor by interleaving the execution steps of each in a time-slicing way, or can be executed in parallel by assigning each computational process to one of a set of processors that may be close or distributed across a network. The main challenges in designing concurrent programs are ensuring the correct sequencing of the interactions or communications between different computational executions, and coordinating access to resources that are shared among executions. A number of different methods can be used to implement concurrent programs, such as implementing each computational execution as an operating system process, or implementing the computational processes as a set of threads within a single operating system process.
