View CPU information in LINUX

Linux command: cat/proc/cpuinfo use the command to determine the number of physical CPUs and cores: number of logical CPUs: # cat/proc/cpuinfo | grepprocessor | wc-l number of physical CPUs: # cat/proc/cpuinfo | grepphysicalid | sort |...

 

Linux command: cat/proc/cpuinfo

 

Use commands to determine the number of physical CPUs and cores:

 

Logical CPU count:

# Cat/proc/cpuinfo | grep "processor" | wc-l

 

Number of physical CPUs:

# Cat/proc/cpuinfo | grep "physical id" | sort | uniq | wc-l

 

Number of cores in each physical CPU:

# Cat/proc/cpuinfo | grep "cpu cores" | wc-l

 

Is it hyper-threading?

If two logical CPUs have the same core id, hyper-threading is enabled.

 

The number of logical CPUs (possibly core, threads, or both) in each physical CPU:

# Cat/proc/cpuinfo | grep "siblings"

 

To sum up, read the physical CPU book, read physincal_id, and start from 0. then, check the number of cores of each CPU.

Core_id
