ISSP Deploys Six Generation Supercomputer System “Ohtaka”, Theoretical Operation Performance with 6.9 Petaflops, Open for All Users

The University of Tokyo

The Institute for Solid State Physics of the University of Tokyo, ISSP (Director Hatsumi Mori), has deployed the new supercomputer system “Ohtaka” provided by Dell Technologies to address computing issues for research including synthesizing new substances, fabricating new nanostructures, and developing unique measurement methods.

With a 6.9 PFLOPS theoretical calculation performance (2.6 times the performance of the old supercomputer system) the Ohtaka supercomputer system is one of the best in Japan. Ohtaka is expected to accelerate the efficiency of large-scale numerical calculations and simulations required for condensed matter physics research.

Having been adopted for ISSP’s core supercomputing system in August 2020, Ohtaka became fully operational and available to researchers nationwide from October.
