Uncore性能监视器表示per-socket资源,该资源不受操作系统执行的上下文切换和线程迁移的影响,建议监视软件代理建立固定的亲和力绑定,以防止不同uncore PMU的事件计数之间的串扰。 计数器寄存器和控制寄存器的编程接口属于两个地址空间: Accessed by MSR are PMON registers within the Cbo units, PCU, and U-Box, see ...
1:NUMA nodes per socket(NUMA NPS每个处理器插槽的NUMA的节点)绝大部分是应用在服务器处理器上的,譬如AMD 霄龙3255简单科普下吧:Non-Uniform Memory Access(非统一内存访问)首字母缩写就是:NUMA,是一种应用于CPU(绝大部分是服务器CPU)上的架构。在NUMA架构出现前,CPU开始是朝着主频越来越高的方向发展,但受到...
For information on how to setup a monitoring session, refer to Section 2.1, "Uncore Per-Socket Performance Monitoring Control". 2.2.2.1 UBox PMON Registers - On Overflow and the Consequences (PMI/Freeze) If an overflow is detected from a UBox performance counter and its overflow enable bit (...
To see uncore events that are attributed a group of PCIe devices on each socket, in the right corner of the timeline section, select thePackage/IO Unit/Uncore Event Short Name/Uncore Event Typegrouping. Use the formulae described earlier in this recipe to understand the behavi...
I would certainly recommend checking for the latest update for your system and then looking for the PCI configuration space registers for the QPI Link Layer counters. The easiest way to check is with the "lspci" command. There will be two entries for each socket in your system if ...
Is this per-socket or global-system wise? E.g., if an address is hashed into a remote socket's L3 slice, does it mean a local L2 miss needs to go across QPI/UPI? For local socket memory, it seems L3 slice will generate/collect snoops messages in the first round, and then send...
