How do you calculate bisection bandwidth?

How do you calculate bisection bandwidth?

For Hyper-cube topology with n nodes, n/2 links should be broken to bisect the network, so bisection bandwidth is bandwidth of n/2 links.

What is full bisection bandwidth?

The full bisection bandwidth allows one half of the network nodes to communicate simultaneously with the other half of the nodes. Assume that half of the nodes inject data into the network at a rate B Mbps. When the bisection bandwidth is B then the network has full bisection bandwidth.

What is bisection width & bisection bandwidth?

● Bisection width = minimum number of links cut to. divide the network into two halves. ● Bisection bandwidth = bandwidth of above.

What is a torus network?

Abstract: Torus networks are an attractive topology in supercomputing, balancing the tradeoff between network diameter and hardware costs. The nodes in a torus network are connected in a k-dimensional wrap-around mesh where each node has 2k neighbors.

What is the bisection width of a topology?

Bisection-width: The bisection-width (bw) of a network is the minimum number of edges (or links) to be removed to disconnect the network into two halves of equal size. In case of an odd number of nodes, one half can include one more node.

What is network diameter?

Diameter of a network It is the shortest distance between the two most distant nodes in the network. In other words, once the shortest path length from every node to all other nodes is calculated, the diameter is the longest of all the calculated path lengths.

What is a 2D torus?

1D torus is a simple circle, and 2D torus has the shape of a doughnut. At one dimension, a torus topology is equivalent to a ring interconnect network, of a shape of a circle. At 2D, it is equivalent to a 2D mesh, but with extra connection at the edge nodes, which is the definition of 2D torus.

Is a donut a torus?

In geometry, a torus (plural tori, colloquially donut) is a surface of revolution generated by revolving a circle in three-dimensional space about an axis that is coplanar with the circle.

What is the different between bisection width and the diameter of a network topology for a distributed memory architecture?

Diameter: The diameter (diam) of a network is the length of the longest of all shortest paths between any two nodes. Bisection-width: The bisection-width (bw) of a network is the minimum number of edges (or links) to be removed to disconnect the network into two halves of equal size.

Which of the following is not a type of network topology?

The types of topology are bus topology, ring topology, star topology, mesh topology and hybrid topology. Connect is not one of them.
