About: Torus fusion

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Torus fusion (tofu) is a proprietary computer network topology for supercomputers developed by Fujitsu. It is a variant of the torus interconnect. The system has been used in the K computer and the Fugaku supercomputer (and their derivatives). Tofu has a six-dimensional mesh/torus topology, a scalability of over 100,000 nodes, and full-duplex links that have a peak bandwidth of 10 GB/s (5 GB/s per direction). Each node is connected to its own InterConnect Controller (ICC) chip, which contains four Tofu interfaces (one for the node and three for connecting to other ICC chips) and a router.
