What is physical ID in Cpuinfo?

/proc/cpuinfo is one of the few places where you get information about what hardware implements these threads of execution: physical id : 0 siblings : 4 core id : 0 cpu cores : 2. means that cpu0 is one of 4 threads inside physical component (processor) number 0, and that’s in core 0 among 2 in this processor.Click to see full answer. Moreover, what is siblings Cpuinfo?The number of siblings on a processor is the total number of execution units within that processor. This will include both additional cores and hyperthreading. For example, A Core 2 Duo will list siblings : 2 . Dual core, no hyperthreading.Additionally, how do I find the physical CPU count in Linux? You can use one of the following command to find the number of physical CPU cores including all cores on Linux: lscpu command. cat /proc/cpuinfo. top or htop command. nproc command. hwinfo command. dmidecode -t processor command. getconf _NPROCESSORS_ONLN command. Regarding this, what is a physical CPU core? Physical cores are number of physical cores, actual hardware components. Logical cores are the number of physical cores times the number of threads that can run on each core through the use of hyperthreading. for example, my 4-core processor runs two threads per core, so I have 8 logical processors.What is CPU family in Proc Cpuinfo?The file /proc/cpuinfo displays what type of processor your system is running including the number of CPUs present. cpu family – Authoritatively tells you the type of processor you have in the system. If your computer is an Intel-based system, simply place the number in front of “86” to determine the value.
