In the last blog post, we talked about how to get the results of executing the command line in Linux, and eventually get CPU usage, but unfortunately it is:1) via Top-n 1 | The CPU usage obtained by the GREP CPU is not refreshed, and the results of the first execution are only available for each read.2) may cause a con
the code:As you can see, Max_prio is 140, which is the kernel-defined maximum priority.And Max_user_prio is 40, meaning that the normal process specifies a priority level of up to 40, as we said earlier-20 to +19.The nice value is-20 is the highest, which corresponds to how much static_prio? Nice_to_prio (0) is 120,nice_to_prio (-20) is 100.When the process has just been forked out by its parent process, the remaining time slices of its parent process are split evenly. After the time slice is e
phenomenaSometimes there is a very strange phenomenon, regardless of the configuration of a few CPUs, but in the Win7 system, only see 2 CPU: Configured 4CPU, in the processor to see is 4, but only use 2:
reason1. Windows 7 supports up to two CPU sockets and can have multiple core within each socket.

But the long test results are as follows: The horizontal axis of the ROS receives the number of event, in 40000 units. (x, Y) indicates that when Ros receives the x*40000 event, the bandwidth of the receiving end is Y gbits/s. Event size is 2KB. As can be seen
Nginx does not turn on using multicore CPUs by default, we can make full use of multicore CPUs by adding worker_cpu_affinity configuration parameters. CPU is the task processing, compute the most critical resources, the more CPU cores, the better performance.

principle of caching is that when the CPU needs to read a piece of data, it first looks for it from the cache. if it finds it, it immediately reads it and sends it to the CPU for processing. If it does not, it reads data from the memory at a relatively slow speed and sends it to the CPU for processing. At the same time, it transfers the data block of the data to
CPU scheduling, multi-channelProgramThe basis of the operating system.
The computer's throughput refers to the number of processes processed by the computer per unit of time.
CPU scheduling improves the computer throughput by switching the CPU between processes.

slices are only related to nice values. In fact, the kernel will have a dynamic adjustment of 5 to +5 for the initial nice value. What is the basis of this dynamic adjustment? Quite simply, if the CPU is using a lot of processes, the nice value is higher, which is equivalent to the priority lower point. The CPU uses less process, think it is the interactive process, then the nice value is lowered point, th
What is APU
The full name of APU is "Accelerated processing Units". The Chinese name is "Acceleration processor". The innovation of APU is to break the boundaries between CPU and GPU, and ultimately unify CPU and GPU from technology, production and application, in terms of structure, "obtain what is needed", "pay-as-you-go" on applications, and "merge into one" on products. But the performance of the two-in
