/proc/cpuinfo

Processor: The number of the logical processing cores in the system. For a single-core processor, the class is considered its CPU number, and for multicore processors it can be a physical core, or a virtual logical core using Hyper-Threading Technology

Physical id  : The label of a single CPU
siblings      : Number of logical physical cores for a single CPU
Core id       : The number of the current physical core in its CPU, which is not necessarily contiguous

CPU Cores: The physical core number of the CPU at which the logical core is located

If the number of CPUs cores and the number of siblings are the same, hyper-threading is not enabled, otherwise Hyper-threading is enabled.

Number of query system CPUs: Cat/proc/cpuinfo | grep "Physical ID" | Sort | Uniq | Wc-l

Number of logical CPUs:
# Cat/proc/cpuinfo | grep ' Processor ' | Wc-l
