分布式計算(Distributed Computing)是一種通過多台互聯的計算機協同處理任務的系統設計模式。其核心在于将複雜任務分解為多個子任務,由網絡中的不同節點并行執行,最終整合結果。這種模式通過資源共享和負載均衡提升效率,同時具備容錯能力。
并行處理與任務分解
分布式系統将大規模計算任務(如基因組分析或氣候模拟)分割成小單元,分配給多台設備同時處理。例如SETI@home項目利用全球志願者的計算機資源分析射電望遠鏡數據。
去中心化架構
系統不依賴單一控制節點,而是通過共識算法(如Raft協議)或分布式哈希表(DHT)實現節點間的協調,典型應用包括區塊鍊網絡和Apache Hadoop框架。
容錯與可靠性
通過冗餘存儲和心跳檢測機制,系統能在部分節點故障時繼續運行。Google的MapReduce模型即采用數據副本和任務重啟策略保障穩定性。
該技術概念由計算機科學家Leslie Lamport在20世紀70年代的形式化研究奠定基礎,相關理論在《IEEE并行與分布式系統彙刊》中有系統性論述。
分布式計算(Distributed Computing)是一種計算機系統設計模式,其核心思想是将一個複雜的任務分解為多個子任務,并通過網絡連接的多個獨立計算機(節點)協同完成。這些節點可以是物理設備(如服務器、個人電腦)或虛拟機,它們通過消息傳遞或共享存儲進行通信和協調。
該技術正推動着邊緣計算、物聯網等新興領域的發展,其數學基礎常涉及分布式算法設計,例如拜占庭容錯問題的解決方案可表示為: $$ begin{cases} n geq 3f + 1 text{其中:} n = text{總節點數} f = text{最大容錯節點數} end{cases} $$
