The scene was mr . cruncher s private lodging in hanging - sword - alley , whitefriars : the time , half - past seven of the clock on a windy march morning , anno domini seventeen hundred and eighty . mr . cruncher himself always spoke of the year of our lord as anna dominoes : apparently under the impression that the christian era dated from the invention of a popular game , by a lady who had bestowed her name upon it 时间：安诺多米尼一干七百八十年三月一个刮风的早晨七点克朗彻先生总把“安诺多米尼”说成“安娜多米诺” ，显然以为基督教纪元是从一个叫安娜的女士发明了多米诺骨牌，而且用自己的名字为它命名而开始的。
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 同时提出一种新的检查点机制，避免了多米诺效应和活锁，并且利用检查点机制，应用linux中页面的换出原理，实现了对进程的上下文以及其他状态以可执行文件格式保存在磁盘，从而使该进程能在节点发生故障的情况下，将故障机的进程迁出，然后选择其他正常节点机，从断点处继续运行，最终达到对该进程的迁移，并且实现系统负载平衡。
