Depends on how the OS schedule threads to CPUs, and how applications set their threads 'processor affinity
In Windows, the operation system does the allocation for you based on CPU usage. you can set the affinity but, it will not determine which processor you run on. on the Xbox 360, the affinity is needed otherwise the 360 will not allocate your threadA s
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
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
The code used to control the CPU usage through C ++ in the previous section to display the sine curve is rewritten with C #, which is better.

Pay attention to the computer hardware description of the person, basically know that the cup is running speed, this speed is actually representative of the CPU in the normal working state of the speed. As with the car engine, because the manufacturer to protect the quality of the CPU, so the speed is not its fastest frequency, and more than the limit frequency is much lower, so the
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
Generally speaking, the bulk of the CPU does not have a radiator and the package is a year, and the boxed CPU is with the radiator of the quality package is three years. From a technical point of view, there is no essential difference between bulk and boxed CPUs, at least in terms of quality. Theoretically, there is no gap in performance, stability, and overclocking potential between boxed and bulk products
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 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
How to obtain the serial number of a specified CPU in a multi-core, multi-CPU systemSkyjacker(Please keep it intact and indicate the author and source)http://www.cnpack.orgCnpack IV QQ group:1309702007-01-23Thanks: Passion,bahamut, Good morning, air, skyjacker ...Without the Bahamut, there is no such article.In multi-CPU and multicore, different serial numbers ar
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 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
Q: Can the CPU fan be universal, if not general how to choose the CPU fan? (I use the Sai Yang 2.4G)
For:
The CPU fan is generic and is not generic. Common in the market is not universal fan, cheaper, universal fan belongs to high-end products, is recommended by DIY enthusiasts, the price is more expensive.1, if you just want to install a fan 2.4G, then go to t
