Linux命令(15)lscpu命令
lscpu命令
- 功能说明:显示有关CPU架构的信息
- 用法: lscpu
[root@node1 ~]# lscpuArchitecture: x86_64CPU op-mode(s): 32-bit, 64-bitByte Order: Little EndianCPU(s): 4On-line CPU(s) list: 0-3Thread(s) per core: 1Core(s) per socket: 2Socket(s): 2NUMA node(s): 1Vendor ID: GenuineIntelCPU family: 6Model: 60Model name: Intel(R) Core(TM) i5-4590 CPU @ 3.30GHzStepping: 3CPU MHz: 3292.419BogoMIPS: 6584.83Hypervisor vendor: VMwareVirtualization type: fullL1d cache: 32KL1i cache: 32KL2 cache: 256KL3 cache: 6144KNUMA node0 CPU(s): 0-3Flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss ht syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon nopl xtopology tsc_reliable nonstop_tsc 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 tsc_adjust bmi1 avx2 smep bmi2 invpcid xsaveopt arat
一些信息的说明:
- Architecture:指CPU的架构
- CPU(s):指CPU的核数
- Thread(s) per core:指的每个 Core 的硬件线程数,超线程,数值为1,表示不支持超线程
- Core(s) per socket:指的是CPU的核心(单个CPU的核心)
- Socket(s):指的是主板上CPU的插槽,服务器通常会有多个
以上信息显示为2个CPU插槽,2个核心,所以它是一个4(2x2)核的CPU。
