The lscpu command displays information about the CPU architecture, which is collected from the sysfs and the /proc/cpuinfo file.

Method-3: How to find the number of CPUs on Linux using the lscpu Command It is part of the GNU Coreutils package, which is installed by default on most Linux systems. It prints the number of processing units available for the current process.

This is the sample data I took from my system. See the following details for better understanding of this in real-time. This improves processor throughput and improves overall performance in threaded software. Intel’s hyper-threading technology makes it possible to use processor resources more efficiently by running multiple threads in each core (each core has two threads). Similarly, a quad core CPU has four central processing units and an octa core CPU has eight central processing units. Initially, CPUs use to come with single core, but manufacturers added more cores to increase performance, which is why the core came into the picture.įor example, a dual-core CPU has two central processing units, so it appears to be two CPUs per operating system.
This is called a physical CPU (central processing unit). What’s a CPU Socket?Ī CPU socket or CPU slot is a connector on the motherboard that allows a computer processor to connect to the motherboard. Hope this article helps you understand exactly what it is.
All Linux systems run on multi-core CPU processors, but many of us are confused to find or understand CPU, cores, and Threads information.
