Why do we use more dimensions in a torus network?

Why do we use more dimensions in a torus network?

The main motivation for more dimensions in a torus is to maintain a low latency when connecting a big number of nodes. For example, if you wanted to connect N=1000 nodes with a 2D torus, you would need a 32×32 grid.

What is torus in parallel computing?

A torus interconnect is a switch-less network topology for connecting processing nodes in a parallel computer system.

What is a topological torus?

Topologically, a torus is a closed surface defined as the product of two circles: S1 × S1. This can be viewed as lying in C2 and is a subset of the 3-sphere S3 of radius √2. This topological torus is also often called the Clifford torus.

What is the diameter of a torus?

Assuming a 2-D torus, the diameter will be the number of links required to get from the center to one of the corners (any further and we can just go in the opposite direction). Thus we will have to traverse (op-12) over each dimension, thus the diameter is D = /p – 1 for a p processor torus.

What is hypercube interconnection network?

In computer networking, hypercube networks are a type of network topology used to connect multiple processors with memory modules and accurately route data. Hypercube networks consist of 2m nodes, which form the vertices of squares to create an internetwork connection.

What is multiprocessor network topologies?

Multiprocessor system consists of multiple processing units connected via. some interconnection network plus the software needed to make the processing units. work together.

How many connections are there in a mesh network?

Suppose, N number of devices are connected with each other in a mesh topology, then the total number of dedicated links required to connect them is NC2 i.e. N(N-1)/2. In Figure 1, there are 5 devices connected to each other, hence the total number of links required is 5*4/2 = 10.

How many switches does a hypercube interconnection network with 64 processors have?

Fat-trees.

Property 2D mesh Hypercube
Max/Avg hop count 14/7 6/3
I/O ports per switch 5 7
Number of switches 64 64
Total number of links 176 256

What is multiprocessing in computer architecture?

multiprocessing, in computing, a mode of operation in which two or more processors in a computer simultaneously process two or more different portions of the same program (set of instructions).

Is the universe simply connected?

The usual assumption is that the universe is, like a plane, “simply connected,” which means there is only one direct path for light to travel from a source to an observer. A simply connected Euclidean or hyperbolic universe would indeed be infinite.

How many holes does the human body have topology?

For a normal human male, discounting pores, we have 9 holes. So our skin homeomorphic to a disk with 8 holes and has fundamental group the free group on 8 generators.

What is a human topologically?

Human Topology. Topology is the branch of mathematics that describes the fundamentals of networks, shapes and the general interconnectedness of things. Topologically speaking, the human body and a ring doughnut have exactly the same shape.

How many links are needed for 5 devices in a mesh topology?
