We can use the lscpu or nproc command to display the number of processing units available to the current process.
all server will not support this system .
nproc Example
The nproc command shows the number of processing units available:
# nproc
Sample outputs:
8
lscpu Command
lscpu gathers CPU architecture information form /proc/cpuinfon in human-read-able format:
# lscpu
Sample outputs:
Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 8 On-line CPU(s) list: 0-7 Thread(s) per core: 1 Core(s) per socket: 4 CPU socket(s): 2 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 15 Stepping: 7 CPU MHz: 1866.669 BogoMIPS: 3732.83 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 4096K NUMA node0 CPU(s): 0-7
/proc/cpuinfo
The /proc/cpuinfo and sysfs stores info about your CPU architecture ike number of CPUs, threads, cores, sockets, NUMA nodes, information about CPU caches, CPU family, model, bogoMIPS, yte order and much more:
# less /proc/cpuinfo
