Fujitsu designs leaner supercomputer with fewer switches |
July 16, 2014
Fujitsu has developed an approach to cluster supercomputers that reduces the number of network switches by 40 percent without sacrificing performance.The approach centers on using a new communications algorithm that efficiently controls data transmissions as well as deploying a multilayer full-mesh topology in the arrangement of the network.Compared to a three-layer “fat-tree” network topology, which employs a tree-like structure of connections, the multilayer full-mesh topology eliminates a layer of switches through more efficient mapping.Meanwhile, scheduling data transfers avoids data collisions along the same paths when each server is communicating with every other server.To read this article in full or to leave a comment, please click here
