What is bisection bandwidth give example?

In computer networking, if the network is bisected into two partitions, the bisection bandwidth of a network topology is the bandwidth available between the two partitions. Bisection should be done in such a way that the bandwidth between two partitions is minimum.

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 the bisection width for a 6d hypercube?

Bisection width It is given as 2m-1 for Hypercubes.

Why is bisection width important?

The bisection width of interconnection networks has always been important in parallel computing, since it bounds the amount of information that can be moved from one side of a network to another, i.e., the bisection bandwidth. Finding its exact value has proven to be challenging for some network families.

What is the diameter of an N node hypercube?

The attractiveness of the hypercube topology is its small diameter, which is the maximum number of links (or hops) a message has to travel to reach its final destination between any two nodes. For a hypercube network the diameter is identical to the degree of a node n = log2N.

What is a torus network?

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 a good bandwidth?

The FCC says the best ISPs for two or more connected devices and moderate to heavy internet use should offer at least 12 megabits per second (Mbps) of download speed. For four or more devices, 25 Mbps is recommended.

Is a high bandwidth good or bad?

Have plenty of bandwidth. When it comes to bandwidth, less is not more. If you always have more bandwidth than you actually need, you are increasing your chances for low latency and better internet performance when it comes to transferring data.

What is an n-dimensional hypercube?

In geometry, a hypercube is an n-dimensional analogue of a square (n = 2) and a cube (n = 3). It is a closed, compact, convex figure whose 1-skeleton consists of groups of opposite parallel line segments aligned in each of the space’s dimensions, perpendicular to each other and of the same length.

How many nodes are there in a hypercube structure for N 2?

The hypercube topology has multiple paths between nodes and a low overall diameter of n for a network of 2n nodes.
