1 socket, core, thread(1) Socket is the number of slots on the motherboard to plug the CPU, that is, the administrator said "road"The chip manufacturer encapsulates one or more cores on a chip, called a socket. Assuming a slot has two cores, the motherboard is plugged into 2 slots, which is the 4-core system.(2) Core is what we usually call "nuclear", that is, dual-core, 4-core and so on. Single-core (Single-core) and multicore (multi-core) are also k

In multiple CPUs and multiple cores, different serial numbe

Knowledge about Linux CPU and Linux CPU What is the difference between hyper-threading and multithreading? Hyper-threading is understood from the hardware layer, that is, a CPU component (which can be understood as a core) executes multiple commands at the same time, which means that multiple threads are executed at the same time.Multithreading is a concept at th

How to view CPU configuration information in Linux, and how to view cpu configuration in linux Enter the command: cat/proc/cpuinfo Check the number of physical IDs in the output result. If 0 is displayed, there is only one physical cpu; Check the number of processor output results. If there are 0 and 1, there are two logical CPUs. (1) Concepts ① Physical

This is a creation in Article, where the information may have evolved or changed. First, the conclusion is listed in the front: Golang performance can be very good, but some native package performance is likely to be retarded, such as RegExp and Encoding/json. If used in high performance requirements, we should optimize according to the actual situation. The use of ON-CPU/OFF-CPU flame dia

Under Linux/unix, CPU utilization (CPU utilization) is divided into user state, System State and idle state, respectively, the CPU is in user state execution time, system kernel execution time, and idle system process execution time. Usually referred to as CPU utilization refers to: the

Possible factors:1. Ambient temperatureThe cpu temperature has a lot to do with the ambient temperature. It will be a little higher in summer. Generally, the temperature is less than 50 ° when the CPU is idle, less than 65 ° when the CPU is busy, and less than 75 ° when the CPU is working at full speed. In

Http://bbs.xiyuit.com/thread-4143-1-1.htmlplease stay tuned for matching the CPU bandwidth and memory bandwidth! Don't let the memory slow down the CPU. Intel's CPU has certain requirements on memory bandwidth since P4. Why did Intel have to push Rambus to match P4? This is because both SDRAM and ddr ram are insufficient to meet P4's needs. For details, FSB is P

CPU scheduling and cpu schedulingBecause the processor is the most important computer resource, improving the utilization rate of the processor and improving the system performance (throughput and response time) depends largely on the Processor Scheduling Performance, processor Scheduling becomes one of the central issues in operating system design.I. Layers of Processor Scheduling1. Advanced scheduling: it

when you go to computer city to buy a personal computer when the shopping guide will ask you about the general use of computers, in fact, they are to help you calculate the computer performance you need, including the calculation of the maximum load on the CPU, of course, they will not be so to calculate, but according to the price, because the high-priced CPU often better performance, Then, they will ask

First, the concept① Physical CPUThe number of CPUs in the actual server slot on the physical CPU, the number of physical IDs that can be repeated is several② Logical CPU③CPU Number of coresThe number of chipsets that can process data on a CPU, such as the current i5 760, is a dual-core four-thread

Qualcomm ARM CPU vs. Intel x86 CPU Performance ComparisonWith the advent of the mobile internet era, arm-based CPUs such as Qualcomm (Qualcomm), Texas Instruments (Texas Instruments) have received more and more attention, while the former king's Intel x86 architecture seems to be struggling in the mobile internet due to power consumption issues.The Intel x86 architecture, compared to the arm architecture, i

CPU instruction design, in addition to naming, it is more important to analyze how the instructions can be achieved. For the CPU structure of Figure 3 1, if the instruction is pre-placed in the Irom, then the instruction is executed with one piece of irom removed from the IR instruction register and provided to the control for analysis execution. How each instruction is transformed into a machine action, th

CPU is the core of the computer hardware, but also the computer hardware in the heat, so the CPU cooling fan speed, the fundamental computer cooling. What about the CPU fan speed? Generally you will choose to see the BIOS settings, but the BIOS needs to restart the computer, and the operation is relatively complex. Today, the WiFi sharing master teaches you a ver

In the previous section, we talked about CPU usage control through PerformanceCounter. Last connection: http://www.bkjia.com/kf/201110/107758.html This section describes how to implement a sine curve for controlling CPU usage. Within a period of time, adjust the CPU usage display by controlling the CPU busy time. Co

CPU fan speed too slow on the CPU is very large, light will cause frequent computer crashes, heavy will cause the CPU burned, and even burned the motherboard and other electronic components, resulting in a great loss, but the CPU speed too fast on the computer and what effect? is the

CPU utilization good understanding, that is, CPU utilization, more than 75% is higher (also has the argument is 80% or higher). In addition to this indicator, but also in combination with the load average and context Switch rate, it is possible that the high CPU is due to the latter two high indicators. Load Average, this is hard to measure. Online Search a la

One, wall clock time, user CPU time, System CPU time definition and contactClock time (Wall clock time): The time that the clock passes from the start of the process to the end, which contains the time at which the process is blocking and waiting.User CPU Time: Is the user's process to obtain the CPU resources after th

With the improvement of computer performance, the CPU power consumption is also increasing, although now because of improved technology to achieve a certain degree of mitigation in power, but because of the increasing performance of the graphics card in recent years, also began to take the CPU power performance proportional to the old road, power consumption is still a worthy of attention, power consumption

　　the central Processing Unit (PROCESSINGUNIT,CPU) is the computing core and control core of a computer. CPU, internal memory and input/output devices are the three core components of computer. Its function is mainly to interpret computer instructions and to deal with data in computer software. The CPU consists of an operator, a controller and a register, and a b
