A main memory managing arrangement involves allotting a request program to one of three distinct areas of main memory by looking in an area managing table which stores head addresses and the capacities of the respective areas. The areas allocated in main memory correspond to a single OS area, ...
This is why main-memory database systems likeH-Store [2], Hekaton [3], HANA [4], HyPer [5], or Silo [6]eschew(avoid,forgo)buffer management altogether. Relations as well as indexes are directly stored in main memory and virtual memory pointers are used instead of page identifiers. This...

OSTO在实现的时候,尽量避免memory contention,比如以一种scalable的方式选择事务时间戳,避免持有全局状态字段的引用。使用Read-copy-update(RCU)技术[9]来进行内存回收,可以让事务继续安全访问已经被逻辑删除的记录,可以大大地降低读写冲突。RCU需要一种可以识别什么时候被逻辑删除对象可以被安全释放的技术。 图2列出了...
:PC机中的引导加载程序是由BIOS和位于硬盘MBR中的OS Boot Loader(比如LILO和GRUB等)一起组成的,BIOS在完成硬件检测和资源分配后,将硬盘MBR中的Boot Loader读到系统的RAM中,然后将控制权交给OS Boot Loader。Boot Loader的主要运行任务就是将内核映象从硬盘上读到RAM中,然后跳转到内核的入口去运行,即开始启动操作...
