context n. 1.上下文;文章的前后關(guān)系[脈絡(luò)]。 2.(事情等的)關(guān)節(jié),范圍,場合,處境,條件;來龍去脈。 tell the meaning of a word from its context從一個字的上文下推知其字義。 in one context 在一定場合,在某一范圍內(nèi)。 in the context of 在…情況下。 in this context 關(guān)于這一點,在這種場合下。 outside the context of 在…之外。
Gets the amount of physical memory mapped to the process context 獲取映射到進(jìn)程上下文的物理內(nèi)存量。
Containing the number of bytes of physical memory mapped to the process context 包含映射到進(jìn)程上下文的物理內(nèi)存字節(jié)數(shù)的
Number of process contexts currently loaded or running on the operating system 當(dāng)前已裝載或正在運行于操作系統(tǒng)上的流程上下文編號。
The process context only needs switching if a reschedule is between threads in different processes 只有在重新調(diào)度是在兩個進(jìn)程間進(jìn)行的時候,進(jìn)程上下文才被切換。
The reason you may need to access memory outside the current process context is that some drivers create threads in the system process 你需要在進(jìn)程上下文之外訪問內(nèi)存的原因也許是一些驅(qū)動在system進(jìn)程中創(chuàng)建了線程。
This state includes not only the processor registers ( the thread context ) but also the address space accessible to the thread ( the process context ) 這個狀態(tài)不僅僅包含了處理器寄存器(進(jìn)程上下文)而且還包含了線程可訪問的地址空間(進(jìn)程上下文) 。
If you process a request in a different thread which is running in another process context , you would not be able to read user mode memory across process boundaries 如果你處理一個不同線程的請求,而這個線程卻又運行在另外一個進(jìn)程的上下文中,你也許不能正常的跨越進(jìn)程分界線來讀取用戶態(tài)內(nèi)存。
Then use these events to get the completion , orders data , and invalid orders data events by using the corresponding event group and qualifying it with the process context , obtained from the process start events 然后,利用這些事件,通過使用相應(yīng)的事件組并將事件組在流程環(huán)境中加以限定,來得到從流程啟動事件中獲得的完成、定購數(shù)據(jù)和無效的定購數(shù)據(jù)事件。
In this chapter , it puts forward a new system about checkpoint , avoiding the domino - effect and livelock . it realizes the storage of process context and other states with the form of executing file in the diskette by using checkpoint system and applying the page switching principles in linux . consequently , when the process has wrong at the checkpoint , it can move out the process in the fault machine , then choose other normal machine , continue to execute from the interrupted point , finally achieve the process migration and load balance of the system 同時提出一種新的檢查點機制,避免了多米諾效應(yīng)和活鎖,并且利用檢查點機制,應(yīng)用linux中頁面的換出原理,實現(xiàn)了對進(jìn)程的上下文以及其他狀態(tài)以可執(zhí)行文件格式保存在磁盤,從而使該進(jìn)程能在節(jié)點發(fā)生故障的情況下,將故障機的進(jìn)程遷出,然后選擇其他正常節(jié)點機,從斷點處繼續(xù)運行,最終達(dá)到對該進(jìn)程的遷移,并且實現(xiàn)系統(tǒng)負(fù)載平衡。
The formalization of workflow context is studied . the dissertation point out that workflow context is an integration of process context , sub - process context , activity context , role context , personal context and local working environment context . workflow context has an object structure of net shape in part and chain shape on the whole 提出并建立了企業(yè)工作流信息主動共享過程上下文(工作流上下文)的形式化描述,指出工作流上下文是過程上下文、子過程上下文、活動上下文、角色上下文、個人上下文和局部工作環(huán)境上下文的有機統(tǒng)一體,并且在組織結(jié)構(gòu)上是一個局部網(wǎng)狀、整體鏈狀的上下文對象網(wǎng)絡(luò)。
