What is interconnection network in parallel computing?

An interconnection network in a parallel machine transfers information from any source node to any desired destination node. This task should be completed with as small latency as possible. The network is composed of links and switches, which helps to send the information from the source node to the destination node.

How the interconnection network assists parallel processing?

Interconnection networks are the network infrastructure for parallel processing. Networks connect processors to memory elements with optional switching elements. We also learned that parallel processing is parallel computing with computations on multiple processors that are executed at the same time.

What is an interconnected network?

An interconnect (generally speaking) is a physical or logical connection between two electronic devices or networks. In the United States, the term “interconnection” is identified as “the linking of two or more networks for the mutual exchange of traffic” by Title 47 of the Code of Federal Regulations.

What are different network topologies used in interconnection networks for parallel computers?

Interconnects are made of switches and links (wires, fiber). Interconnects are classified as static or dynamic. Static networks consist of point-to-point communication links among processing nodes and are also referred to as direct networks. Dynamic networks are built using switches and communication links.

What is an interconnection network in parallel computer architecture?

What is an Interconnection network in parallel computer architecture? The information is passed from any of the desired source node by using minimal possible latency, to any of the required destination node by using the interconnection network. Huge volumes of information are passed by this method several numbers of times.

How is information communicated in a parallel computer?

In parallel computer systems, the information is communicated among the processors by interconnection network. The interconnection networks are of two types – Direct connection networks – The nodes that are adjacent to each other are connected, which is known as direct connection networks.

What do you mean by interconnection network algorithm?

–Determines number of hops •Routing: Routing algorithm determines path(s) from source to destination B A Terminology •Network interface –Connects endpoints (e.g. cores) to network. –Decouples computation/communication •Links –Bundle of wires that carries a signal •Switch/router

How are network topologies related to parallel algorithms?

In this context, a network topology is essentially a discrete graph \ a set of nodes connected by edges. Distance does not exist and there is no notion of the length of an edge1. ouY can think of each edge as being of unit length. Network topologies arise in the context of parallel architectures as well as in parallel algorithms.
