Thank you for visiting this page, this page has been update in another link lscpu list CPU architecture information
lscpu gathers CPU architecture information from sysfs and
/proc/cpuinfo. The command output can be optimized for parsing or for
easy readability by humans. The information includes, for example,
the number of CPUs, threads, cores, sockets, and Non-Uniform Memory
Access (NUMA) nodes. There is also information about the CPU caches and
cache sharing, family, model, bogoMIPS, byte order, and stepping. Here is the default output of the run# lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 12 On-line CPU(s) list: 0-11 Thread(s) per core: 1 Core(s) per socket: 6 Socket(s): 2 NUMA node(s): 2 Vendor ID: GenuineIntel CPU family: 6 Model: 44 Stepping: 2 CPU MHz: 2660.000 BogoMIPS: 5333.19 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 12288K NUMA node0 CPU(s): 0-5 NUMA node1 CPU(s): 6-11 Customized output format # lscpu -a -e=socket,cpu,core,address,online,configured SOCKET CPU CORE ADDRESS ONLINE CONFIGURED 0 0 0 - yes - 0 1 1 - yes - 0 2 2 - yes - 0 3 3 - yes - 0 4 4 - yes - 0 5 5 - yes - 1 6 6 - yes - 1 7 7 - yes - 1 8 8 - yes - 1 9 9 - yes - 1 10 10 - yes - 1 11 11 - yes - COLUMNS CPU The logical CPU number of a CPU as used by the Linux kernel. CORE The logical core number. A core can contain several CPUs. SOCKET The logical socket number. A socket can contain several cores. BOOK The logical book number. A book can contain several sockets. NODE The logical NUMA node number. A node may contain several books. CACHE Information about how caches are shared between CPUs. ADDRESS The physical address of a CPU. ONLINE Indicator that shows whether the Linux instance currently makes use of the CPU. CONFIGURED
Indicator that shows if the hypervisor has allocated the CPU to the
virtual hardware on which the Linux instance runs. CPUs
that are configured can be set online by the Linux instance. This
column contains data only if your hardware system and hyper- visor support dynamic CPU resource allocation. POLARIZATION
This column contains data for Linux instances that run on virtual
hardware with a hypervisor that can switch the CPU dispatch- ing mode (polarization). The polarization can be: horizontal The workload is spread across all available CPUs. vertical The workload is concentrated on few CPUs.
For vertical polarization, the column also shows the degree of
concentration, high, medium, or low. This column contains data only if your hardware system and hypervisor support CPU polarization. |
