If data needs to be moved to the execution node, then data movement may also need to be scheduled
如果需要將數據移動到待執行的節點上，那麼我們還需要對數據的移動操作也進行調度。 -
We give a new algorithm for dynamic process migration after comparing the existing algorithms ; offer the system users a transparent distributed - os interface by modifying linux kernel and adding a global operation module ; design a migrate protocol so that the client and server can give the consistent view of process and transparent remote execution, and handle link failure and node failure
通過對linux核心的修改，和globaloperation模塊的增添，為用戶提供了一個「透明」的具有進程遷移功能的分散式操作系統介面。設計了一套遷移協議，使客戶機與服務器能提供一致的進程觀點和透明的遠程執行，並處理了網路失敗和節點失敗兩類錯誤。 -
Each computing node can be both a master for locally created processes and a slave for processes migrated from other pcs. when a slave is no longer available ( i. e. being switched back to windows mode ), unfinished tasks are retrieved by the master for continued execution or dispatched to another available linux - pc
每個電腦節點既可以是自行產生程序的主機，也可以是由其他個人電腦轉移程序而至的從屬機。當某部從屬機不再可供使用時（即轉回到windows模式） ，主機將索回未完成的工作，或分派給另一臺已轉用linux系統操作的個人電腦，繼續進行未完成的工作。 -
Node ids in showplans identify each operation the query optimizer performs when it generates a query execution plan
Showplan中的節點id標識查詢優化器在生成查詢執行計劃時執行的每個運算。
