Bisection Bandwidth

What is bisection bandwidth?The minimum bandwidth available between two equal-sized partitions of a network.

Bisection bandwidth is a measure of network performance, defined as the bandwidth available between two equal-sized partitions when a network is bisected. This measure accounts for the bottleneck bandwidth of the entire network, providing a representation of the true bandwidth available in the system. The bisection should be done in a way that minimizes the bandwidth between the two partitions. It is often used to evaluate and compare networks for parallel architectures, including point-to-point communication systems or on-chip micro networks.
