, which is not exactly the same thing as the threading ID that pthread_t in POSIX.The thread implemented by the POSIX line libraries in Linux is actually a lightweight process (LWP), which is the true PID of this thread.But it cannot be obtained through the getpid () function, which defines the Gettid () interface in Linux, but is usually not implemented, so it is necessary to obtain the TID in the following way.Program#include 1, CPU affinity (

Affinity PDO, affinity Network Cause I have never paid attention to database-related knowledge. A few months ago, I did not intend to open the following code: It was written N years ago. Later, it was also necessary for learning. It was no longer appropriate for a single mysql. So I searched the internet for a good method, and PDO came on the way. Temptation Whe

Windows Azure currently has eight big data centers worldwide (US West, US east, North Central US, South Central US, Nordic, Western Europe, East Asia, South Asia). There are two data centers in North and south of China. Each data center consists of several "containers", the inside of which is a cluster (cluster) and a rack (rack). Each container has a specific service, such as compute and storage, SQL database and service bus, access control services (an Access control service), and so on.Not on

Algorithm friend number pair for large number affinity pair, large number affinity pair After a couple of days of affinity, I finally got an ac connection this evening. It's not easy. Let's talk about my practices. I hope I can help you. The questions are as follows: Description Numbers 220 and 284 are a pair of youyuan numbers, because the sum of all factors of

Nginx uses the multi-process master/worker structure, the worker process number is the CPU number is the highest efficiency, nginx through the affinity for each worker process binds a CPU, avoids the process switching to bring the consumption, simultaneously can guarantee the cache hit ratio.Nginx configuration file conf/nginx.conf for the number of worker processes, and affinity configuration commands:Work

Since I first came into contact with Cognos, I have never understood "affinity". What is "affinity? I once asked Cognos technical support, and he did not give me a very clear answer. The following content is translated by me according to a document. There must be many places that are not in place, I hope you will give me more advice. Affinity connectionThe

Part 1: Background and preparation Roger Johansson of this "evaluating website Accessibility" trilogy, written is quite practical, for the Web site affinity is very suitable for the introduction. At the end of this article, there is a slight deletion. Special thanks to hlb and othree , hehe, this article thanks to them. Around the world, more and more countries are starting to ask governments and public service websites to be standards-based and to fo

The most intuitive benefit of binding a process to the CPU is to reduce cache synchronization and switching between CPUs, increase the hit rate of the CPU cache, and improve the efficiency of the Code.From the CPU architecture, NUMA has independent local memory, the nodes can be exchanged between the modules to connect and information interaction, so each CPU can access the entire system of memory, but access to remote memory access efficiency is greatly reduced, bound CPU operation on such syst

The method of adjusting affinity This section describes how to improve process-to-CPU affinity, CPU and memory affinity, and the affinity of virtual CPUs to physical CPUs. 1. Binding process For dedicated CPU mode, the binding process can be applied to the specified CPU. 2. Adjust CPU parameters For sharing CPU mode, d

as we all know, before the start of a new application project in the real world, we should configure the basic environment according to the requirements of the application environment, such as network, hardware architecture, etc. So in the Windows Azure environment, before we start an application project, we need to configure the virtual network and affinity group according to the requirements of the application environment. This blog post will be a d

In Linux, we know thatNice, reniceCommands change the execution priority of processes, and high-priority processes give priority to execution, so as to ensure the running of important tasks to a certain extent. In addition to Nice and renice, you can use CPU affinity to specify the processors on which processes are running. CPU affinity indicates the tendency of a process to run on a given CPU for as long
