非均匀存储器存取（Nonuniform-Memory-Access，简称NUMA）模型 - - -**UMA模型** - -物理存储器被所有处理机均匀共享。所有处理机对所有存储字具有相同的存取时间，这就是为什么称它为均匀存储器存取的原因。每台处理机可以有私用高速缓存,外围设备也以一定形式共享。 - -**NUMA模型** - -NUMA模式下，处理器被划分成多个"节点"（node）， 每个节点被分配有的本地存储器空间。 所有节点中的处理器都可以访问全部的系统物理存储器，但是访问本节点内的存储器所需要的时间，比访问某些远程节点内的存储器所花的时间要少得多。 - - -#1.2 (N)UMA模型中linux内存的机构 -------- - - - -非一致存储器访问(NUMA)模式下 - -* 处理器被划分成多个"节点"(node), 每个节点被分配有的本地存储器空间. 所有节点中的处理器都可以访问全部的系统物理存储器，但是访问本节点内的存储器所需要的时间，比访问某些远程节点内的存储器所花的时间要少得多 - - -* 内存被分割成多个区域（BANK，也叫"簇"），依据簇与处理器的"距离"不同, 访问不同簇的代码也会不同. 比如，可能把内存的一个簇指派给每个处理器，或则某个簇和设备卡很近，很适合DMA，那么就指派给该设备。因此当前的多数系统会把内存系统分割成2块区域，一块是专门给CPU去访问，一块是给外围设备板卡的DMA去访问 - ->在UMA系统中, 内存就相当于一个只使用一个NUMA节点来管理整个系统的内存. 而内存管理的其他地方则认为他们就是在处理一个(伪)NUMA系统. - -

而不同处理器之前则通过总线进行进一步的连接, 因此相对于任何一个CPU访问本地内存的速度比访问远程内存的速度要快 - -Linux适用于各种不同的体系结构, 而不同体系结构在内存管理方面的差别很大. 因此linux内核需要用一种体系结构无关的方式来表示内存. - -因此linux内核把物理内存按照CPU节点划分为不同的node, 每个node作为某个cpu结点的本地内存, 而作为其他CPU节点的远程内存, 而UMA结构下, 则任务系统中只存在一个内存node, 这样对于UMA结构来说, 内核把内存当成只有一个内存node节点的伪NUMA - - -##2.2 内存结点的概念 -------- - ->CPU被划分为多个节点(node), 内存则被分簇, 每个CPU对应一个本地物理内存, 即一个CPU-node对应一个内存簇bank，即每个内存簇被认为是一个节点 -> ->系统的物理内存被划分为几个节点(node), 一个node对应一个内存簇bank，即每个内存簇被认为是一个节点 - -内存被划分为结点. 每个节点关联到系统中的一个处理器, 内核中表示为`pg_data_t`的实例. 系统中每个节点被链接到一个以NULL结尾的`pgdat_list`链表中<而其中的每个节点利用`pg_data_tnode_next`字段链接到下一节．而对于PC这种UMA结构的机器来说, 只使用了一个成为contig_page_data的静态pg_data_t结构. - - -内存中的每个节点都是由pg_data_t描述,而pg_data_t由struct pglist_data定义而来, 该数据结构定义在[include/linux/mmzone.h, line 615](http://lxr.free-electrons.com/source/include/linux/mmzone.h#L615) - - -在分配一个页面时, Linux采用节点局部分配的策略, 从最靠近运行中的CPU的节点分配内存, 由于进程往往是在同一个CPU上运行, 因此从当前节点得到的内存很可能被用到
