The US Department of Energy on Friday unveiled Summit, a supercomputer capable of performing 200 quadrillion calculations per second, or 200 petaflops. Its performance should put it at the top of the list of the world’s fastest supercomputers, which is currently dominated by China. From a report (thanks to reader cb_abq for the tip): Summit, housed at the Oak Ridge National Laboratory (ORNL), was built for AI. IBM designed a new heterogeneous architecture for Summit, which combines IBM POWER9 CPUs with Nvidia GPUs. It has approximately 4,600 nodes, with six Nvidia Volta Tensor Core GPUs per node — that’s more than 27,000. The last US supercomputer to top the list of the world’s fastest was Titan, in 2012. ORNL, which houses Titan as well, says Summit will deliver more than five times the computational performance of Titan’s 18,688 nodes.
