Green500:聯想AI服務器再次蟬聯全球最綠色算力
格隆匯7月14日丨根據最新Green500榜單顯示,美國紐約Flatiron研究所的Henri高性能計算集羣以65.40GFlops/W(每瓦654億次浮點運算)的能效,再次奪得Green500排行榜第一名。更重要的是,經過進一步的系統改進,Henri系統在TOP500榜單上的成績有了更優異的表現。其排名從去年11月份的第405位提升至第255位,當前HPL(高性能Linpack基準測試)得分為2.88PFlops(每秒2880萬億次浮點運算)。Flatiron研究所的Henri高性能計算集羣由聯想集團搭建。Henri採用了聯想ThinkSystem SR670 V2 AI服務器。這款AI服務器採用3U高密度設計,搭載兩個第三代英特爾至強可擴展處理器,不僅最早支持NVIDIA的Hopper旗艦型GPU,更可以支持龐大的NVIDIA Ampere數據中心產品組合。最新的Henri系統具備了14個計算節點,NVIDIA H100 GPU數量增至112套,在算力有效增強的前提下,能效也得到了進一步提升。聯想ThinkSystem SR670 V2是全球第一個採用NVIDIA H100 PCIe協議的AI服務器。SR670 V2獨特的體系結構沒有將PCIe顯卡“硬連接”到特定的CPU,而是允許將GPU動態分配給CPU。先進的系統設計思路,允許客户可根據其正在運行的作業,優化系統的GPU資源。
