Lamport's bakery algorithm is a computer algorithm devised by computer scientist Leslie Lamport, as part of his long study of the formal correctness of concurrent systems, which is intended to improve the safety in the usage of shared resources among multiple threads by means of mutual exclusion.
the Paxos algorithm for consensus, the bakery algorithm for mutual exclusion of multiple threads in a computer system that require the same resources at the same time, the Chandy–Lamport algorithm for the determination of consistent global states (snapshot), and; the Lamport signature, one of the prototypes of the digital signature.
Lamport's bakery algorithm uses a similar concept of a "ticket" or "counter" but does not make the use of atomic hardware operations. It was designed for fault tolerance rather than performance. Rather than all processors continuously examining the release counter, the bakery lock spins on examining the tickets of its peers. [3]
Dekker's algorithm; Peterson's algorithm; Lamport's bakery algorithm [7] Szymański's algorithm; Taubenfeld's black-white bakery algorithm [2] Maekawa's algorithm; These algorithms do not work if out-of-order execution is used on the platform that executes them. Programmers have to specify strict ordering on the memory operations within a ...
Peterson's algorithm (or Peterson's solution) is a concurrent programming algorithm for mutual exclusion that allows two or more processes to share a single-use resource without conflict, using only shared memory for communication. It was formulated by Gary L. Peterson in 1981. [1]
The Chandy–Lamport algorithm is a snapshot algorithm that is used in distributed systems for recording a consistent global state of an asynchronous system. It was developed by and named after Leslie Lamport and K. Mani Chandy .
A New York City bakery has responded to claims made by actor and The View host Whoopi Goldberg that her order was refused because of her political views.. Goldberg, who has been a co-host on The ...
In theoretical computer science, a certifying algorithm is an algorithm that outputs, together with a solution to the problem it solves, a proof that the solution is correct. A certifying algorithm is said to be efficient if the combined runtime of the algorithm and a proof checker is slower by at most a constant factor than the best known non ...
