TSUBAME 2.0 supercomputer, a large scale heterogeneous system with Intel processors and > 4,000 NVIDIA GPUs, operation of which has started in November 2010. The main part of this system consists of about 1,400 compute nodes, each of which is equipped with two CPUs and three GPUs. The nodes are connected via full bisection fat tree network of Dual-Rail QDR InfiniBand. The theoretical peak performance reaches 2.4PFlops, 30 times larger than that of the predecessor TSUBAME 1.0, while its power consumption is similar to TSUBAME 1.0. We conducted improvement and tuning of Linpack benchmark considering characteristics of large scale systems with GPUs, and achieved Linpack performance of 1.192PFlops. This is the first result that exceeds 1PFlops in Japan, and ranked as 4th in the latest Top500 supercomputer ranking. Also TSUBAME 2.0 has received “the Greenest Production Supercomputer in the World” prize in Green500 ranking for its performance power ratio of 958MFlops/W.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"179","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS）"}],"bibliographicPageStart":"169","bibliographicIssueDates":{"bibliographicIssueDate":"2011-10-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"4"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:33:31.118575+00:00","id":78062,"links":{}}
