The number of Linux CPUs is judged by/proc/cpuinfo.Same Physical ID: determines a physical processorIf "siblings" and "CPU cores" are consistent, hyper-threading is not supported, or hyper-threading is not open.If "siblings" is twice Times "CPU cores", then hyper-Threading is supported and Hyper-threading is turned on.In fact, just#include Long num = sysconf (_SC_NPROCESSORS_ONLN);You can get the current number of CPUs ...Basis of judgment:1.

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.

How to identify the number of physical CPUs, a few cores, is hyper-threading or multi-core 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 same socket. Insta

CPU's operating speed also depends on the CPU's pipeline of various aspects of performance indicators. Of course, the frequency and the actual speed is related, can only say that the clock is only the performance of the CPU one aspect, and does not represent the overall performance of
