In fact, as long as
#include Long num = sysconf (_SC_NPROCESSORS_ONLN);
You can get the current number of CPUs ...
Judge the basis:1. CPUs with the same core ID are the same core hyper-threading.2. CPUs with the same physical ID are the same CPU-encapsulated threads or cores.
English version:1.Physical ID and core ID are not necessarily consecutive but they unique. Any CPUs with the same core ID are hyperthreads in the same core.2.Any CPU with the same physical ID are threads or cores in the
Copan System is a leader in an enterprise-class intelligent storage solution.

Founded in 2002, the company's goal is to develop products based on the unique requirements of long-term
Sometimes you need to collect various information about the server, such as CPU information, memory information, Linux version information, and various software information installed. The following describes how to view the main indicators. 1. view the Linux release information [root @ pcmweb ~] # Cat/etc/issue

/cpuinfo | grep flags | grep 'lm '| wc-l4
(If the result is greater than 0, 64bit computing is supported. lm indicates long mode, and lm indicates 64bit)

1. Check whether your computer's CPU supports Virtualization:
grep -E "vmx|svm" /proc/cpuinfo
If the printed result is as long as the following:

/proc provide the latest information about the physical environment of the system. Although the files in/proc are virtual, they can still be viewed using any file editor or a program like ' more ' or ' less ' or ' cat '. When the editor tries to open a virtual file, the file is created from a thin air (on the fly) through the information in the kernel. Here are some interesting results I got from my system: $ ls-l/proc/cpuinfo-r--r--r--1 root root 0 Dec 11:01/proc/cpuinfo$ file/proc/cpuinfo/proc
