A ribbon-cutting ceremony in Princeton’s High-Performance Computing Research Center on Sept.30 kicked off the University’s official launch of its newest supercomputer,called Traverse,which joins four other distinct computing clusters available to the University research community.“We are delighted to unveil Traverse,our new Department of Energy(DOE)‘Leadership Class’compatible computing cluster,”said David McComas,vice president for the Princeton Plasma Physics Laboratory(PPPL)and professor of astrophysical sciences.“This is an important milestone in Princeton University’s increased collaboration with the DOE in support of basic plasma physics and the U.S.fusion energy mission.”Traverse is a1.4 petaflop High-Performance Computing(HPC)cluster that shares the same Graphics Processing Unit(GPU)and Central Processing Unit(CPU)architecture as the supercomputers at Oak Ridge National Laboratory(ORNL)and Lawrence Livermore National Laboratory.Traverse is currently one of the largest systems at Princeton and in the top 500 systems in the world.Curt Hillegas,associate CIO,Research Computing,Office of Information Technology and the Princeton Institute for Computational Science and Engineering(PICSciE)and amember of the PPPL advisory board who led the project to purchase and install the cluster,said:“Traverse is amini version of ORNL’s Summit,thereby providing astepping stone for the research community to one of the world’s fastest supercomputers.Getting experience using Traverse will allow our research groups to adapt their codes,so they can use the current leadership-class machines and be best prepared for the new exascale systems—capable of at least one exaFLOPS,or abillion billion calculations per second—expected to come online in the upcoming two years.”Exascale speeds are expected to help fusion researchers finally clear the remaining hurdles in the development of safe and sustainable fusion energy.“At that scale we will be able to simulate and optimize fusion reactors,speeding the deployment of fusion energy in the global battle against climate change,”explained Steven Cowley,PPPL director.“We are very grateful to the University for this marvelous facility.”Plasma,the hot ionized gas that fuels fusion reactions,must be heated to very high temperatures for the particles to fuse and release their energy.The focus of much fusion research is preventing the swings in density and temperature that cause instabilities such as plasma disruptions,edge localized modes and energetic-particle driven modes.Machine learning(ML)techniques are helping researchers create better models for rapid control and containment of plasma. 查看详细>>
