In software architecture, a messaging pattern is an architectural pattern which describes how two different parts of an application, or different systems connect and communicate with each other. There are many aspects to the concept of messaging which can be divided in the following categories: hardware device messaging (telecommunications ...
Ian Graham reviewed the first volume in the Journal of Object-Oriented Programming. [2] DBMS columnist David S. Linthicum found the first volume to be "the best book on patterns for application architects", while Bin Yang of JavaWorld thought it had "many interesting architecture and design patterns". [3] [4]
After (p-1) communication rounds, every message is distributed to its destination. The time taken by this algorithm is (+) (). [2] Here is the startup cost for a communication, and is the cost of transmitting a unit of data. This term can further be improved when half of the messages are sent in one and the other half in the other direction.
In computer science, Linda is a coordination model that aids communication in parallel computing environments. Developed by David Gelernter , it is meant to be used alongside a full-fledged computation language like Fortran or C where Linda's role is to " create computational activities and to support communication among them".
A programming model is an execution model coupled to an API or a particular pattern of code. In this style, there are actually two execution models in play: the execution model of the base programming language and the execution model of the programming model. An example is Spark where Java is the
Broadcast is a collective communication primitive in parallel programming to distribute programming instructions or data to nodes in a cluster. It is the reverse operation of reduction. [ 1 ] The broadcast operation is widely used in parallel algorithms, such as matrix-vector multiplication, [ 1 ] Gaussian elimination and shortest paths .
Collective operations are building blocks for interaction patterns, that are often used in SPMD algorithms in the parallel programming context. Hence, there is an interest in efficient realizations of these operations. A realization of the collective operations is provided by the Message Passing Interface [1] (MPI).
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.
