Abstract

本发明实施例提供了多线程访问多副本的方法和装置。该方法包括：当进程的多个线程被分布到不同节点时，创建与进程的进程页目录表的内容相同的线程页目录表，每份线程页目录表包括用于指向特定数据的特殊表项和特殊表项之外的普通表项，其中每个线程对应一份线程页目录表，每个线程的执行基于相对应的线程页目录表，特定数据是在不同节点具有多副本的数据；对于每个线程在被调度时，当该线程的线程页目录表中的特殊表项未指向在该线程所在节点中存储的特定数据时，基于该特定数据的物理地址，修改该特殊表项以指向该特定数据。基于上述技术方案，可以使分布到不同节点的线程访问所在节点处存储的数据副本，从而提高系统性能。
