Mainly responsible for collecting some basic information of the client, this is also fully customizable, can be customized in the client, and then automatically report up, you can also from the server-side definition and push down, after the acquisition, and then report up grains information is static; pillar and grains compare his flexibility, Define that definition, and then take the value.Usage of grains:1[email protected] ~]#

The KVM structure contains information such as Vcpus, memory, and Apic,irq,mmu,event event management. The information in this structure is primarily used inside a KVM virtual machine to track the state of a virtual machine.For a KVM, it corresponds to a thread.KVM takes full advantage of hardware virtualization technology to view information via Cat/proc/cpuinfo, and if it is an Intel processor, load Kvm-intel.koThe user state creates a virtual machi

"dispatch domain" (scheduling domains), but this does not affect our understanding of the thread switching mechanism. (2) In multi-core scenario, which CPU is interrupted? Soft interrupts (including dividing by 0, page faults, int instructions) are naturally generated on the CPU that triggered the interrupt, and there are two cases of a hard interrupt, one for each CPU itself, such as a clock, which is handled by each CPU itself, and an external interrupt such as IO, The

Only talk about external interrupts for Windows kernel Management, exceptions and traps are not listed in this article.1. Windows interrupts overall appearanceIn Windows, the physical interrupt source is abstracted into the kinterrupt structure. An interrupt source corresponds to a kinterrupt array in Windows, the length of the array is the number of CPUs, and if it is a single-core system, the array length is 1. The kinterrupt results are analyzed first.Windows stores IDT (Interrupt descriptor

Cat/proc/cpuinfo: you can see the actual number of cpu cores in detail. it should be the cpucores parameter value, the number of physical CPUs, and the number of non-repeated physicalids. There are several [user @ localhost ~] # Cat/proc/cpuinfoprocessor nb Cat/proc/cpuinfo to view detailed cpu information The actual number of cores should be the value of cpu cores, the number of physical CPUs.

Even if you have a 64-bit processor, you may not be able to run a 64-bit Windows XP operating system. A message from OS News said that Microsoft's latest 64-bit operating system cannot be installed on Asus laptops Based on the athlon64 platform. THG has been confirmed by Asus a few days ago. It is true that the software cannot run on existing devices. "We are currently trying to make windows 64-bit work on our laptop platform and will announce our support plans in the next few weeks," said As
