The max degree option on dsntip4 determines the maximum degree of parallelism maximum number of parallel tasks Dsntip4上的max degree選項決定了最大并行度(并行任務的最大數量) 。
I recommend that you evaluate the virtual storage capacity and constraints in your z os environment , and adjust this parameter as needed , so that db2 will not create more parallel tasks than your virtual storage can handle 我建議您先估計z / os環境中的虛擬存儲能力和局限性,這樣db2就不至于創建多于虛擬存儲所能處理的并行任務。
For example , an application consisting of many independent parallel tasks executes much faster when the tasks are spread across a large number of compute resources than by using a single server or cluster 例如,與使用單個服務器或群集執行的執行速度相比,包含多個獨立并行任務的應用程序在將任務劃分到大量計算資源上,其執行速度要更快一些。
Some improvements are made to enhance the generic algorithm ' s stability self adaptability and optimization efficiency . based on the ttg model , the co - synthesis method can map parallel task graphs to multiple processing unlts 本文提出了基于改進遺傳算法解決軟硬件協同綜合問題的新方法,基于ttg模型,該方法能夠實現多并發任務流在多處理單元結構上的映射。
As for the sequential and parallel processing , which exists in the field of cscw , temporal constrains are used to describe the temporal relations between the sequential and parallel tasks . an application , which contains sequential and parallel sub - tasks , is shown as an example at last 同時,文中分析了協同工作中存在的串行和并行工作,采用時態約束描述了串、并行任務間的時序關系,并描述了一個并行協同工作的實例。
Although this and my previous twelve scheduling tips are not an exhaustive list of ways to improve scheduling , i m confident that acknowledging and plotting your parallel tasks in this way will provide some ease to organizations that are taking on increasing workload 盡管這個和我以前的12點時間安排的提示都不是對改進時間安排的詳盡的方法列表,我相信用這種方法來承認和測繪并發的任務可以為那些負擔增加工作負荷的組織提供一些方便。
Firstly , we need consider more in cooperation and message - pass between parallel tasks . secondly , the parallel design pattern is different from that of sing - alone program . thirdly , parallel program has to call complicated apis to accomplish data transfer 首先,并行程序的分析與設計需要更多的考慮各并行任務的協同和消息通信機制;其次,并行程序的編寫模式與單機程序不同;最后,并行程序需要調用并行平臺的復雜的通信原語來完成數據的傳送。
In chapter 3 we construct two approximation algorithms which applying bin packing algorithms for scheduling problems , one is ff ( first fit ) algorithm used in parallel machine scheduling problem pm / / dj = d / n which has a lower bound of asymptotic worst - case performance ratio , another problem is scheduling independent parallel tasks in parallel identical machine systems to minimize the makespan , we use strip packing method for it and give an approximation algorithm with asymptotic performance ratio no more than 1 . 6 第一個算法利用裝箱問題中的ff ( firstfit )算法求解極大化按期完工工件數的平行機排序問題pm d _ j = d n - u _ j ,該近似算法具有漸近性能比下界。第二個近似算法利用二維裝箱中strippacking問題的算法求解以極小化makespan為目標的帶并行工件的平行機排序問題,該算法的漸近性能比具有下界1 . 5和上界1 . 6 。
It preestablish a parallel design pattern for each parallel project based on master / slave architecture , and the communication between computers is transparent to programmers . in another words , when programmers are developing parallel programs , they do n ' t need to learn any complicated primitives and write any codes related with communication between parallel tasks . just only set some parameters in the visual interfaces that provided by platform , and the codes will be generated by our system automatically and inserted to the fittest place in the files 系統為每一個并行計算工程設定了一個基于master slave架構的并行編程模型,并且使得各結點機之間的通信對于開發人員透明化,也就是說,開發人員在開發并行程序時,無需了解紛繁復雜的通信原語,不涉及任務之間通信的代碼,只需要在并行程序開發平臺提供的可視化界面上對數據的傳送進行設定,通信代碼將自動生成并插入到程序合適的地方。
