In non-uniform memory access (NUMA) architecture, a NUMA node is a fundamental component that includes a processor and local memory. These nodes are physically separate b
NumaNode 类型公开以下成员。 属性 展开表 名称说明 AffinityMask Gets or sets the affinity type for the NUMA node represented by this NumaNode object. Cpus Gets a collection of Cpu objects that belong to this NumaNode object. GroupID Gets the GroupID that is assigned to this NUMA node. ID...
使用NUMA 時,即使初始的免費記憶體不平均地分散在節點之間,SQL Server 也會以相當於非 NUMA 系統的比率,從作業系統接收記憶體。 緩衝集區嘗試盡量取得每一個節點的本機記憶體;不過,這樣做很難,因為 Windows 目前沒有 API 可從特定節點配置記憶體。 當記憶體指派至 SQL Server 時,您可能會注意到,有些節點得到...

Accordingly, hardware NODE 0 has less local memory available for other applications than the other nodes. This problem is accentuated when there is a large system file cache. When SQL Server starts on a computer with more than one NUMA node, it tries to start on a NUMA node other than ...
NUMA_NO_PREFERRED_NODE 0xffffffff 首选无 NUMA 节点。 这与调用CreateFileMapping函数相同。 返回值 如果函数成功,则返回值是文件映射对象的句柄。 如果在函数调用之前存在该对象,该函数将返回现有对象的句柄(其当前大小,而不是指定大小),GetLastError函数返回ERROR_ALREADY_EXISTS。
由于底层硬件架构和应用层 workload 的多样性,实际需要考虑和权衡的因素还有很多,而这一切,都是由一套被称为automatic NUMA balancing的框架来完成的(可通过"/proc/sys/kernel/numa_balancing"来打开或者关闭)。 AutoNUMA 的主要依据是尽量减少 remote access,但随着硬件技术的进步,跨 node 的内存访问延迟已经有了很...
使用libvirt绑定numa node 初学libvirt,感觉还挺方便的。它能够像daemon一样运行一个稳定的VM,相比直接用qemu命令行是方便多了。这里记录一下我如何绑定numa node。 不知道能不能直接在创建虚拟机的时候绑定numa,我是在xml中设置的。 安装libvirt,略去。在host上创建一个网桥,libvirt以它上网,我这里命名为virbr0...
