first section CPU utilization and CPU load
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 tim
CPU Ladder Figure 2016 the latest version of the CPU how to see performance?
How does the CPU look at performance? This is a problem that friends of computer enthusiasts often ask. Today, the script House finally brings up the latest version of CPU Ladder 2016, through the latest
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
the difference between CPU bulk and boxed
From the technical point of view, the bulk and boxed CPU is not the essence of the difference, at least in terms of quality and performance does not exist problems, more impossible to have a fake CPU (no manufacturers can counterfeit such high-tech products), of course, do not rule out profiteers after grinding to low fr
The CPU cache query tool in Linux and the cpu cache query in linux
In Linux, you can use the following tool to query the CPU cache:
Method 1:
$ Lscpu
L1d cache: 32 K
Method 2:
$ cat /sys/devices/system/cpu/cpu0/cache/index0/size32K
$ cat /sys/devices/system/cpu/cpu0/cac
Remove the installation of memory, graphics, etc. are not difficult, but remove the CPU on the motherboard is not easy, a little attention may damage the CPU and motherboard slots, each CPU and CPU fan installation is not necessarily the same, but the same. The following details the computer how to remove the

The relationship between the maximum memory and CPU supported by the computer, and the maximum memory cpu supported
When using a computer, the maximum supported memory is determined by the operating system and hardware.
In terms of hardware, the number of CPU address bus determines the IP address range of the CPU in th

The CPU is the most complex, most expensive SOC (chip) on the phone, which is also the location of the brain in the cell phone, and is the decisive hardware for the performance of the mobile phone. The development of smartphones to today, the major mobile phone CPU manufacturers from the spring and autumn warring States gradually to the current four-country separation of the Times (Qualcomm, MTK, Samsung, a

The most intuitive benefit of binding processes/threads to CPUs is to increase the hit rate of the CPU cache, thereby reducing memory access loss and increasing the speed of the program. I think that under the NUMA architecture, this operation has a significant impact on the speed of the system, and in the SMP architecture the promotion may be relatively small. This is mainly because both the cache, bus, the allocation of these resources are different
What is a computer CPU? Cup is the CPU (central processing unit), which is the computing core and control core of a computer. CPU, internal memory and typing/output devices are the three core components of the computer. CPU is the brain of the computer, more than 90% of the data information is done by it. Its speed of
The last article on how to use LoadRunner monitor Linux performance indicators, but the CPU on a few indicators are not clear, the following detailed said.
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
Understanding the system structure from the Java perspective serial, follow my Weibo (link) Learn about the latest developments it is well known that the CPU is the brain of the computer, which is responsible for executing the instructions of the program; Memory is responsible for saving data, including the program's own data. As we all know, memory is much slower than CPU. In fact, 30 years ago, the
From the software point of view of the CPU, it seems that the CPU is a series of instruction symbols. Therefore, we design a CPU, first of all to consider which instructions should be designed. The instruction system of the computer needs to be planned according to the requirement of the task, there will be arithmetic operation instruction, logic operation instru
High CPU usage is a frequent problem for netizens, CPU usage is actually the CPU resources that you run the program, which means that your machine runs a lot of programs at this time. Long-term use will make the CPU for a long time in the hot state will affect the impact of the CPU
In electronic technology, the pulse signal is a pulse signal continuously sent at a certain voltage range and at a certain interval. The interval between pulses is called a cycle, and the number of pulses generated per unit time (for example, 1 second) is called a frequency. Frequency is the metering name that describes the number of pulses that appear in a periodic cycle signal (including a pulse signal) per unit time. The standard unit of measurement for a frequency is Hz ). The system clock i
Do you want to know the performance of your CPU?Do you think the testing software is too troublesome?Do you think it would be great to have free testing software?
Now, you can download my own test_cpu program to test your CPU performance ~Simply run the test_cpu.exe program in double-click mode. Wait for 30 seconds to 2 minutes (depending on the performance of the machine) and you will see the result ~
