concurrency mechanism
What is concurrency in operating systems?
Many operating systems allow a large number of tasks to be run concurrently and the simultaneous use of peripheral devices. The earliest applications of concurrency were in real-time systems such as operating systems, in which the software must perform actions at times determined by external events.
What is concurrency theory?
Concurrency theory has been an active field of research in theoretical computer science. One of the first proposals was Carl Adam Petri 's seminal work on Petri nets in the early 1960s. In the years since, a wide variety of formalisms have been developed for modeling and reasoning about concurrency.
How do concurrency control mechanisms work?
Concurrency control mechanisms firstly need to operate correctly, i.e., to maintain each transaction's integrity rules (as related to concurrency; application-specific integrity rule are out of the scope here) while transactions are running concurrently, and thus the integrity of the entire transactional system.
