Most of the communication primitives presented in this article share a common template. [2] Initially, each processing element possesses one message that must reach every other processing element during the course of the algorithm. The following pseudo code sketches the communication steps necessary.
In computer science, inter-process communication (IPC), also spelled interprocess communication, are the mechanisms provided by an operating system for processes to manage shared data. Typically, applications can use IPC, categorized as clients and servers , where the client requests data and the server responds to client requests. [ 1 ]
The message-passing paradigm is attractive because of wide portability and can be used in communication for distributed-memory and shared-memory multiprocessors, networks of workstations, and a combination of these elements. The paradigm can apply in multiple settings, independent of network speed or memory architecture.
Unlike device communications, where the form of the message data is limited to protocols supported by the type and capabilities of the devices involved (for example in computer networking we have the TCP and UDP protocols, a walkie-talkie would sending radio waves in specific frequency, and a beacon would be flashing Morse code sequences that a ...
The communication time of the algorithm is βm + αlog p + √ 4αβmlog p, [7] so the startup latency is only one half of the startup latency of the two-tree broadcast. The drawback of the ESBT broadcast is that it does not work for other values of p and it cannot be adapted for (non-commutative) reduction or prefix sum.
Network architecture is the design of a computer network.It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used.
The Berkeley socket API is a general interface for networking and interprocess communication, and supports the use of various network protocols and address architectures. The following lists a sampling of protocol families (preceded by the standard symbolic identifier) defined in a modern Linux or BSD implementation:
CSP provides two classes of primitives in its process algebra: events and primitive processes. Events. Events represent communications or interactions. They are assumed to be instantaneous, and their communication is all that an external ‘environment’ can know about processes. An event is communicated only if the environment allows it.
