As we enter the era of peta-scale computing, system architects must plan for machines composed of tens or even hundreds of thousands of processors. Although fully connected networks such as fat-tree configurations currently dominate HPC interconnect designs, such approaches are inadequate for ultra-scale concurrencies due to the superlinear growth of component costs. Traditional low-degree interconnect topologies, such as 3D tori, have reemerged as a competitive solution due to the linear… CONTINUE READING
