Parallel Computing | 平行運算

  • 平行運算是什麼?
    平行運算(Parallel Computing )是指同時使用多種計算資源解決計算問題,在過程中讓許多指令同時進行的一種運算模式,基礎概念是將須計算的內容分割成離散部分,再運用多執行續的方式同時解決。

  • 為何需要?
    傳統的序列計算模式是指在單個計算機(具有單中央處理器)上執行軟體運算。CPU 照順序使用一系列指令解決問題,但其中同一時間只有一種指令可以執行運作。平行運算是在序列計算的基礎上演變而來,目的是模擬自然世界中的狀態:事件會同時發生並可以同時並行處理,依照此原理才可更加速複雜指令的處理速度,減少運算的時間。

  • 技嘉的特色
    技嘉的G系列伺服器有多種GPU運算加速卡擴充插槽的選項,運用GPU多核心的優勢更可以讓平行運算的效益呈倍數成長。G291-2G0能在2U機箱中容納多達16張NVIDIA T4加速卡。適用於人工智慧學習中推論的工作負載,例如:語音辨識、圖像與視頻處理、線上購物或影片串流的推薦系統等…應用。NVIDIA Tesla T4專門用來加速橫向擴充伺服器,減少10倍推論延遲,並提供比CPU高出40倍的驚人能源效率。

    GIGABYTE is pleased to publish our first long-form “Tech Guide”: an in-depth, multipart document shedding light on important tech trends or applications, and presenting possible solutions to help you benefit from these innovations. In this Tech Guide, we delve into the making of “Data Centers”—what they are, who they are for, what to keep in mind when building them, and how you may build your own with products and consultation from GIGABYTE.
    How to Pick a Cooling Solution for Your Servers? A Tech Guide by GIGABYTE
    As CPUs and GPUs continue to advance, they consume more power and generate more heat. It is vital to keep temperature control in mind when purchasing servers. A good cooling solution keeps things running smoothly without hiking up the energy bill or requiring persistent maintenance. GIGABYTE Technology, an industry leader in high-performance servers, presents this tech guide to help you choose a suitable cooling solution. We analyze three popular options—air, liquid, immersion—and demonstrate what GIGABYTE can do for you.
    Decoding the Storm with GIGABYTE’s Computing Cluster
    Waseda University, the “Center for Disaster Prevention around the World”, has built a computing cluster with GIGABYTE’s GPU server and tower servers. They use it to study and prepare for natural disasters, such as tsunamis and storm surges. Efforts go into understanding the tropical cyclones of tomorrow, which are thought to become more dangerous due to climate change.
