This article mainly with the vast number of computer enthusiasts to share without software how to see the CPU is a dual-core or a single core? Please see the relevant hardware knowledge Introduction: Software View Method: 1, in Task Manager, right-click the taskbar Point Task Manager, select the Performance tab, if the dual-
A question was discussed with a reader friend last night:on a multi-core CPU Web server, there is a load imbalance, in which the load of CPU0 is significantly higher than other cpux, further investigation indicates that the PHP-FPM suspicion is very large. I have previously documented a similar problem with soft interrupts, but in this case we can exclude suspects.Let's sample the data on a four-
1. What is "atomic operation ":An atomic operation is an uninterrupted operation or a series of operations that are not interrupted by the thread scheduling mechanism. There is no context switch during the operation ).2. Why do we focus on atomic operations?1. If an operation is determined to be atomic, you do not need to add a lock that will consume expensive performance overhead to protect the operation.-(clever use of atomic operations and implementation of lock-free programming)2. mutex can
, he can only work hard, increase productivity to the limit. Therefore, multithreading is more efficient than multiple cores. Do I buy a multi-core processor or a multi-thread processor? So when we purchase a CPU, do we purchase a multi-core CPU?) or a multi-thread CPU? I pe
Single-core, multi-core CPU atomic operationI. What is an "atomic operation":Atomic operations are: one or a series of operations that cannot be interrupted, that is, operations that are not interrupted by the thread scheduling mechanism, without any context switches during the run.Two. Why focus on atomic operations?1. If it is determined that an operation is at
When the Multi-Core CPU is installed on the accelerated route, it is only shown as a single core in the system. 1, if the CPU is indeed multi-core, motherboard support is not a problem, you may have a relationship with the BIOS settings, set the method as follows: Post, pre
Article Title: How does one determine whether the CPU is dual-core or single-core in Linux. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems, open-source, and other basic categories. In Linux, you can view detailed information about each
In linux, how does one determine whether the cpu is dual-core or single-core-general Linux technology-Linux technology and application information? The following is a detailed description. In linux, you can view the details of each cpu in/proc/cpuinfo. However, for dual-core
Friends recently equipped with a dual-core computer, so that the installed staff installed XP system directly after the home, the results inadvertently open Task Manager, found that the CPU use records only showed a core, suddenly panic, thought to buy a fake. Small series brought over to check, found in the Device Manager does have two

A recent study of virtualization technology inevitably encountered a problem: how to evaluate the capacity of virtual hosts on physical hosts? The ideas in the following article are enlightening. How to determine the number of virtual machines deployed on a CPU core? Abstract:This article describes the ideal number of virtual machines deployed on a CPU
example, No. 0, 1: mask=0x031th, 2: mask=0x06And so onIf the number of CPUs is insufficient, a modulo operation is performed. For example, a total of 4 CPUs, then mask=0x0010 and 0x01 the same.The advantage of this method is that multi-threading does not have to manually select the CPU each time, the disadvantage is that in the event of a high CPU load, then the program execution speed is slow (think alike
Dual core or qua core is very popular now, so everyone should understand the Cortex-A9 in the end. Cortex-A8 is a bit past in smartphone, Cortex-A9 is very popular now, but the real blockbuster application, expert prediction in 2013 ~ 2014. This articleArticleIs I reprint a cattle people abroad on the Cortex-A9 new feature summary, very useful. The arm Cortex-A9 CPU
: The number of logical processing penalty cores in the system. For a single-core processing penalty, the class is considered to be its CPU number, and for multi-core processing the penalty can be physical kernel, or the application of Hyper-threading technique virtual Logical kernelVENDOR_ID:CPU BuildersCPU FAMILY:CPU Product Family CodeModel:cpu belongs to whic
CPU is the soul of a computer, determines the overall performance of the computer. Now the mainstream CPU is multi-core, and some use multithreading technology (hyper-threading, referred to as HT). Multicore may also be easy to understand, believing that a lot of players can say why. But what does hyper-threading really mean, what is the difference between a
Interactive, a market research firm, shows that 48% of PC users are still at a loss about what the dual-core is after AMD has announced its Opteron plan for nearly three years. (Of course, within the industry is another case.) Data center managers and corporate CIOs are well aware of the capabilities that dual-core computing can bring to the enterprise. ) In a survey of home users, 42% of personal-compute
Three cores is simply 3 cores, the core is also called the kernel, is the CPU most important component. The three nuclear products were first developed by AMD. When AMD suddenly announced that it would launch its primary tri-core processor phenom Tripe-core in the first quarter of 2008, the entire industry felt somew
To buy a dual-core computer, you must first understand the dual core. Look at Intel and AMD's respective dual-core, we focus on learning their differences, only after understanding to know, choose which is better, or more cost-effective. To be correct, the use of Intel and AMD's caching is not the same, and can not be directly compared to the version of the cac
Dual-core CPUs and even quad-core CPUs are now quite popular, and Microsoft's latest release of Windows 7 is very well supported for multi-core processors. The survey found that most of the current Windows 7 in the startup process is slow, not fully play the dual-core
