in the hierarchical storage manager, the process of copying data sets which have been opened for reasons other than read only access since the last backup version was created, and meet the backup frequency criteria 在分級存儲管理程序中,復制若干數(shù)據(jù)集的處理方法,這些數(shù)據(jù)集是指從上一個后備版本建立以來,不是由于只讀存取而打開過的,并且滿足備份頻度要求的數(shù)據(jù)集。
novel stack cache architecture and data-forwarding mechanism between it and the execution unit are also presented . the relationship between the capacity and the backup frequency of the stack cache is analyzed too 文中還設計了一種由多體靜態(tài)存儲器構成的堆棧緩沖結構,并在堆棧緩沖和執(zhí)行部件之間采用了數(shù)據(jù)重定向技術,還對緩沖容量和后援頻度的關系進行了理論分析。
