Linux CPU interruption [reprinted], linuxcpu reprinted Interruption is actually a signal sent by hardware or software called IRQ (interrupt request. The interrupt allows devices, such as keyboards, serial ports, and parallel ports, to indicate that they require CPU. Once the CPU receives the interrupt request, the CPU

Hyper-V 3 limits the CPU utilization of virtual machines. Windows Server 2012 is coming soon. The latest Hyper-V 3 brings us more surprises, in the next three blog posts, we will learn about the virtual machine CPU competition mechanism. Part 1: CPU resources allocated to virtual machines; Part 2: limits the CPU usage

/proc/cpuinfo File AnalysisAccording to the following content, we can easily know the current system about the CPU, CPU, the CPU is enabled Hyper-threading and other information. Logical Core: Cat/proc/cpuinfo | grep "Processor" | Wc-l//the ID of the logical processor(number of logical cores)Query systemNumber of CPUs: Cat/proc/cpuinfo | grep "Physical ID" | Sort

No free lunch in the world, this article reproduced in: http://cenalulu.github.io/linux/all-about-cpu-cache/ Let's take a look at a mind map of all the concepts in this article:Why do I need a CPU CacheAs the process has increased in recent decades, CPU frequency has been increasing, and is subject to manufacturing processes and cost constraints, the curren

In fact, as long as #include Long num = sysconf (_SC_NPROCESSORS_ONLN); You can get the current number of CPUs ... Judge the basis:1. CPUs with the same core ID are the same core hyper-threading.2. CPUs with the same physical ID are the same CPU-encapsulated threads or cores. English version:1.Physical ID and core ID are not necessarily consecutive but they unique. Any CPUs with the same core ID are hyperthreads in the same core.2.Any

CPU as the core of PC computer accessories, the probability of failure is not large. The CPU processor in normal use, if not overclocking, generally will not appear any problem. Of course, due to the cooling fan shutdown, the radiator and the CPU bad contact caused by the frequent panic, restart failure is often occurred. For some older

In Linux, you can view CPU and memory usage during system maintenance. you may need to view CPU usage at any time and analyze the system status based on the relevant information. In CentOS, you can use the top command to view CPU usage. After running the top command, CPU usage... in Linux, you can view

For modern CPUs, the performance bottleneck is access to memory. CPU speeds are often at least two orders of magnitude higher than main memory. So the CPU has introduced L1_cache and L2_cache, and the higher-end CPUs have joined the L3_cache. Obviously, this technique raises the next question:If the memory that a CPU needs to access at the time of execution is no

In the Linux operating system, we generally look at the CPU load of the system commonly used commands can be uptime,top, as well as vmstat and so on are all possible. The information provided by each tool is different,I'm going to talk about the CPU section here. Using the uptime command, you can get the operating system in the last 1 minutes, 5 minutes and 15 minutes of the

what is the normal temperature of the CPU? The normal temperature of the CPU AMD processors: AMD Althon, Althon Opteron, Duron and Sempron series AMD Athlon XP 1.33ghz+ 90 degrees AMD Athlon XP t-bred upto 2100+ 90 degrees AMD Athlon XP t-bred over 2100+ 85 degrees AMD Athlon XP Barton 85 degrees AMD Athlon 64 70 degrees AMD Athlon (Socket 939, 1.4 volts) 65 degrees AMD Athlon 70-degree FX AMD At

CPU's frequency, that is, CPU core working clock rate (CPU Clock Speed). It is commonly said that a certain CPU is how many MHz, and this number of MHz is "CPU frequency." Many people think that CPU is the speed of its operation, but it is not. The CPU's frequency indicates

Most users believe that the high-speed download of the Thunderbolt will occupy too high a CPU occupancy rate, which is completely committed to the empirical error. In fact, the thunderbolt can be achieved high-speed, efficient and exist, the overall reduction of CPU occupancy rate. First, traces of the Thunder Why can reduce CPU occupancy rate 1. Deep understan

1.0 OverviewIn the Linux/proc file system, you can see the time slices that start at startup, all CPU consumption, and the time slices that the process consumes for a process. This is a cumulative value that can be "non-blocking" output. The process CPU utilization during this time can be calculated by obtaining two statistics of a certain time interval. So, is there a simple, non-blocking way to get

CPU is one of the main factors affecting Linux performance. Vmstat command: displays brief information about the performance of various system resources.The r in the procs column indicates the number of processes that run and wait for the CPU time slice. If this value exceeds the number of CPU for a long time, it indicates that the

The key to monitoring the CPU and memory of the switch is to find the correct OID, please refer to the following blog post for how to find the OID.http://tryrus.blog.51cto.com/10914693/1788833Before looking at this blog post please make sure that you have an understanding of the basic operation of Zabbix, there is no clear place to read my previous blog post.http://tryrus.blog.51cto.com/10914693/1772271http://tryrus.blog.51cto.com/10914693/1782062Firs

Recently used PHP to do a server load monitoring of small things, on the server using Workerman to open a WebSocket service, and then in the browser to connect to the service. The service reads the information about the host every 10 seconds and sends it to the client for graphical display. The general idea is to use PHP to invoke the shell command and then parse the output of the command. Some minor problems were encountered while getting the CPU lo
