It will work no matter what Linux distribution you are using. All the files in this directory are stored as virtual files and listed as zero bytes yet contain extensive information. Identifying the type of processor using the proc/cpuinfo file does not require installing any additional programs.

bash-3. The simplest way to determine what type of CPU you have is by displaying the contents of the /proc/cpuinfo virtual file. > import platform > platform.

Is my interpretation correct? -bash-3.2$ cat /proc/cpuinfo | grep 'physical id' 10 Answers Sorted by: 38 The platform.processor () function returns the processor name as a string. I interpret this as, core 0, 2, 4 and 6 are the 4 physical cores in processor 1, while core 1, 3, 5 and 7 are the 4 physical cores on processor 0. From the preceding output, we can see detailed information pertaining to the CPU that we ran the cat /proc/cpuinfo command against. It’s actually a virtual filesystem that contains runtime system information such as system memory, devices mounted, hardware configuration etc. Secondly, which core lies on which processor, as there are two quad core processors here, as it is a dual socket system with 8 cores in total. If you are aware of the directory structure in Linux, you already know that proc is a special directory in Linux. My question is which core is hyperthreaded here. So one should interpret this /proc/cpuinfo entry as a 4-core CPU with hyperthreading. If the kernel cares about a feature or KVM. My understanding so far has been that different cores within the same physical CPU would have different core id, and if core id s are identical, this is due to hyperthreading.

Model name : Intel(R) Core(TM)2 Duo CPU T6500 2.I have this info from /proc/cpuinfo (shown below). On x86, flags appearing in /proc/cpuinfo have an X86FEATURE definition in arch/x86/include/asm/cpufeatures.h. For example, /proc/cpuinfo contains information about the systems.
