HPC | 高效能運算

  • 是什麼?
    HPC是高效能運算(High Performance Computing)的簡稱,雖然基本元件組成與個人電腦的概念相似,但是透過軟體平行連結的機制串聯大量高速主機,便可以在更短的時間內完成大量複雜運算的工作,大幅提升應用程式的處理能力。

  • 為何需要?
    現代的HPC運算能力皆可以達到每秒兆級浮點運算次數(PFLOPS),目前世界排名第一的超級電腦甚至可以達到122.3 PFLOPS,一般電腦主機無法處裡的大型運算過程例如醫學生物基因比對、AI自駕車學習、太空衛星發射模擬、天氣氣候預測模型等等領域都會需要HPC的協助。

  • 誰會用到?
    技嘉一直是HPC領域設計的佼佼者,透過H系列超融合基礎架構G系列高效能運算伺服器妥善配置的散熱與高密度設計,以達到最佳的運算效能與能源效率,以台灣國家高速網路與計算中心的算圖農場(Render Farm)案例來說,就引進了技嘉的G481-HA0進行高速的平行運算,提供台灣更多藝術創作者高解析高效能的影音算圖需求。另一個運用的範例則是使用H262 AMD EPYC 7002 系列 "Rome" 2U4節點伺服器,每個節點搭載兩顆AMD EPYC CPU,僅用4個節點就可以在2U伺服器中達成512核 / 1024執行緒的高運算力,如果使用完整42U的位置(保留網路交換器的空間下)更可以達到10240核 / 20480執行緒的超高效能,明顯提升客戶的整體運算能力。
