5/7/2023 0 Comments Cat cpuinfo![]() This command is very useful if you want to get more information about your hardware info, such as CPU or memory. To run it, just type the following command into your terminal: $ dmidecode -t processor | grep "Core Count" It is a command-line tool to retrieve device data that the Linux kernel exposes through MCU. Model name : Intel(R) Xeon(R) Platinum 8259CL CPU 2.50GHzĬheck the physical number of CPU: cat /proc/cpuinfo |grep "physical id"|sort |uniq|wc -lĬheck the number of vCPU: cat /proc/cpuinfo |grep "processor"|wc -l Check CPU cores with dmidecode command in Linuxĭmidecode command can be used to check the number of cpu cores in Linux. To view it, just type the following command into your terminal: cat /proc/cpuinfo This file also contains CPU vendor_id, model name etc. It will list a lot of information about the cpu, including the number of CPU cores on your system. Open the terminal and run this command: cat /proc/cpuinfo. $ lscpu | grep -E '^Thread|^Core|^Socket|^CPU\('Ĭheck CPU cores from /proc/cpuinfo File in LinuxĪnother way to check the number of cpu cores in Linux is by looking at the /proc/cpuinfo file. In the following examples, the number of CPU cores is 1 * 2=2 $ lscpuįrom this example, we can get that the number of CPU cores are 2 * 8 =16 It supports Intel x86, AMD Family 16h/18h, and ARM processors. The lscpu command displays either one single CPU family or all families detected by querying sysfs (on Linux kernels with CONFIG_SYSFS). It gives you a lot of information about cpu, including the number of cores, the vendor_id, model name etc.Įcho "Cores = $(( $(lscpu | awk '/^Socket\(s\)/') ))" Open the terminal and run this command lscpu. ![]() The best way to check the number of CPU cores in Linux is using the lscpu command. The number of vCPU = CPU cores * threads per coreĬheck CPU cores with lscpu command in Linux.The number of CPU cores = sockets * Core per socket.There are 2 threads per core in most of the current CPU architecture. This is different than the number of CPU cores, as it measures the number of tasks that can be processed at the same time. In Linux, threads per core is a way of measuring the number of threads that can be processed simultaneously on a single CPU core. However, it is important to note that not all processors support hyper threading. This can be useful if you are trying to optimize your system for performance, as it can increase the number of tasks that can be processed simultaneously. It allows a single CPU core to process multiple tasks at the same time by creating virtual cores. Hyper threading is a feature that was first introduced in Intel processors. Understanding CPU cores and hyper threading in Linux ![]() This can result in a significant increase in performance.īut the number of CPU cores is not the same as the number of processors. This means that, if you have multiple CPU cores, your system can process multiple tasks at the same time. In Linux, a CPU core is essentially a processor. When you are trying to optimize your system for performance, it is important to understand the concept of CPU cores. The following commands can be used to check the number of CPU cores in Linux. Let’s get started! Methods to get number of CPU cores in Linux ![]() This is useful information to have if you are trying to optimize your system for performance.Įach method has its own advantages and disadvantages, so be sure to read through all of them before choosing the one that is best for you. In this blog post, we will discuss 3 different ways to check the number of cpu cores in Linux. ![]()
