Go has a memory model describing how goroutines must use channels or other operations to safely share data. [98] The existence of channels does not by itself set Go apart from actor model-style concurrent languages like Erlang, where messages are addressed directly to actors (corresponding to goroutines). In the actor model, channels are ...
This model of execution is called run to completion, or RTC. In the RTC model, the system processes events in discrete, indivisible RTC steps. New incoming events cannot interrupt the processing of the current event and must be stored (typically in an event queue ) until the state machine becomes idle again.
The consistency model defines rules for how operations on computer memory occur and how results are produced. One of the first consistency models was Leslie Lamport 's sequential consistency model. Sequential consistency is the property of a program that its execution produces the same results as a sequential program.
The memory model specifies synchronization barriers that are established via special, well-defined synchronization operations such as acquiring a lock by entering a synchronized block or method. The memory model stipulates that changes to the values of shared variables only need to be made visible to other threads when such a synchronization ...
A sample UML class and sequence diagram for the Flyweight design pattern. [6] The above UML class diagram shows: the Client class, which uses the flyweight pattern; the FlyweightFactory class, which creates and shares Flyweight objects; the Flyweight interface, which takes in extrinsic state and performs an operation
Single instruction, multiple data. Single instruction, multiple data (SIMD) is a type of parallel processing in Flynn's taxonomy.SIMD can be internal (part of the hardware design) and it can be directly accessible through an instruction set architecture (ISA), but it should not be confused with an ISA.
A circular buffer first starts out empty and has a set length. In the diagram below is a 7-element buffer: Assume that 1 is written in the center of a circular buffer (the exact starting location is not important in a circular buffer): Then assume that two more elements are added to the circular buffer — 2 & 3 — which get put after 1:
Diagram of a CPU memory cache operation. In computing, a cache (/ k æ ʃ / ⓘ KASH) [1] is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere.
