Torus network topology9/17/2023 The torus-connected cycles topology (TCC) has been introduced after recognising this trend of the supercomputing industry. 1 as of May 2022, the Fujitsu Fugaku, have been relying on it. The K computer, using the features of the 6-dimensional mesh/torus topology, can maximize the computational power of its 80,000 or more CPUs without waste. Hierarchical interconnection networks, and especially torus-based ones have proven very popular: several highly ranked supercomputers, such as the world no. In other words multiple jobs can be assigned very flexibly and efficiently within the overall CPU population. Because the 6-dimensional mesh/torus topology network provides many communication routes between neighboring CPUs, the shapes of the jobs assigned to each CPU group can be flexibly changed. This resembles the situation where you pack as many boxes as possible in a warehouse efficiently, leaving as little wasted space as possible, even when the boxes are of different shapes and sizes. In the K computer, the job management software assigns respective jobs to the CPUs and controls the order of processes. But when assigning CPUs to many jobs, it is more efficient to ensure there is no unnecessary data communication between the CPUs. The K computer therefore assigns the required CPUs to each respective job, based on their process contents from its 80,000 or more CPUs. The K computer is expected to process computations (jobs) from many users simultaneously. Management functions to ensure efficient and maxim CPU performance
