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.
Software support
Tofu's six-dimensional mesh/torus topology is abstracted by software to appear as a three-dimensional torus; it is supported by a Tofu-optimized version of the open-sourceOpen MPIMessage Passing Interface library. Users can create application programs adapted to either a one-, two-, or three-dimensional torus network. ==See also==
