the motherboard. Therefore, FSB is the 533 main version! FSB is speed. Depends on the bus frequency. FSB (Front-End bus) Front side busWithin a PC, one device and the other transmit digital signals through the system bus. The CPU can communicate with memory, video card, and other devices through the front-end bus (FSB. The faster the FSB frequency, the more data the processor obtains per unit of time,

Memory Management Mode Intel's 80x86 series CPU manages memory segments. 1. Memory segmentsThe memory management unit of a computer is linear addressing in bytes,Byte is the basic unit for memory management by 80 x86cpu. To identify each storage unit, a number is assigned to each storage

This article describes how to use cgroups to manage CPU resources. Let's talk about the CPU usage of the control process. When running multiple programs on a machine that may consume a large amount of resources, we do not want a program to occupy all the resources, so that other programs cannot run normally, or the system is suspended for maintenance. At this time, cgroups can be used to control the resourc

0.01, by top-d We can set the CPU usage refresh interval to very low, such as 0.01 seconds. But is too low a refresh rate to be able to more accurately observe CPU occupancy? Is the CPU usage information provided by the Linux system accurate enough?Based on the previous analysis, we know that Linux calculates the CPU

always use the allocated time slice, so the CPU usage will be 100%. In fact, you only need to add a time. sleep (0.001) while the CPU can be lowered. The sleep function tells the operating system that this thread will discard the currently unused time slice and do not assign time slice to me in the next specified time. In fact, the processes in the entire operating system are waiting for sleep for most of

Generally, for processes that require a large amount of CPU computing, the higher the front-end pressure, the higher the CPU utilization. However, for I/O network-intensive processes, even if there are many requests, the CPU of the server may not be very good. At this time, the Service bottleneck is generally on the disk I/O. In a long view, the

Nowadays, there is no uniformity in the naming of the same thing on the Internet. It seems like there are many types of things, so it is necessary to clarify the clues first, find out the equivalence relationships between different names: 1. CPU external frequency = External frequency 2. CPU frequency = clock speed 3. Frontend bus frequency 4. System bus frequency 5. MultiplierRelationships: The externa

: Jiffies. Jiffies represents time. Its units vary depending on the hardware platform. A constant Hz is defined in the system, representing the number of minimum time intervals per second. So the jiffies unit is 1/hz. The Intel platform Jiffies Unit is 1/100 seconds, which is the minimum time interval the system can distinguish. Each CPU time slice, jiffies must

swap zone and then into the memory, but the used swap zone has not been overwritten. this value is the size of the swap zone where the content already exists. When the corresponding memory is swapped out again, you do not have to write data to the swap zone. Detailed information about each process is displayed at the bottom of the process information area. First, let's take a look at the meaning of each column. Serial number column name meaning a PID process id B PPID parent process id c RUSER

class) 61 is the combination of sub commands. Process a sequence of commands: Fetch) In the value phase, the instruction bytes are read from the memory and put into the instruction memory (CPU). The address is the value of the program counter (PC. It calculates the address of the next instruction of the Current Instruction in order (that is, the PC value plus the length of the obtained instruction) Decode) ALU reads a maximum of two operands from a
