This nproc command helps you find number of CPU-Cores in Linux directly without any grep or calculation as below. You can use several specific commands to pull CPU information from your hardware, regardless of whether you use bare metal or virtualized hardware. In the above out put it’s clearly mentioned number of CPU’s as 4 against the “CPU(s)” heading. The Linux CLI can provide you with detailed CPU information, such as the number of CPU cores, CPU architecture and CPU usage. Model name: Intel(R) Xeon(R) CPU E5-2676 v3 2.40GHz You can also find number of CPU-Cores in Linux using lscpu command.
#Linux get cpuinfo how to#
Here in this case we have got 4 CPU’s ,numbers ranging from 0 to 3. How to determine number of CPU sockets on my Red Hat Linux Use the grep command along with wc command and sort command as follows: grep physical. (See below for sample processor output. Processor : ~]# cat /proc/cpuinfo|grep processor|wc -l To see what type of processor/CPU your computer system has, use this Linux command: cat /proc/cpuinfo As you can see, all you have to do is use the Linux cat command on this special /proc/cpuinfo file on your Linux system. Hence to find number of CPU-Cores in Linux with exact details use below commands: ~]# cat /proc/cpuinfo|grep processor Model name : Intel(R) Xeon(R) CPU E5-2676 v3 2.40GHzįlags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx pdpe1gb rdtscp lm constant_tsc rep_good nopl xtopology eagerfpu pni pclmulqdq ssse3 fma cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand hypervisor lahf_lm abm fsgsbase bmi1 avx2 smep bmi2 erms invpcid xsaveoptĪddress sizes : 46 bits physical, 48 bits virtual /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. cat /proc/cpuinfo (Image credit: Tom's Hardware) This command will produce. This gives in depth information about the CPU such as vendor_id, cpu family, model, cpu MHz etc. One of the most common way to get CPU information is to check the content of /proc/cpuinfo. Use the cat command to display the data held in /proc/cpuinfo.
) In other words, they represent the four cores of a single Intel i3 CPU. (Note that they all have the same physical id. In order to get cpu information you need to simply cat “/proc/cpuinfo” file within proc. 3 Answers Sorted by: 17 The entries are logical processors objects used by the kernel internally, not necessarily tied to physical devices. To Learn more about Proc file-system follow this link. This proc is an pseudo filesystem which keeps track of run-time environment. In order to find number of CPU-Cores in Linux we can take help of proc file system. Question: How to find number of CPU-Cores in Linux. Now we are going to discuss about how to find number of CPU-Cores in Linux. In my earlier post we had discuss about how to find top CPU consuming in Linux.
