Linux to view the number of physical CPU, core, and logical CPU
Total number of cores = number of physical CPU X number of cores per physical CPU
Total logical CPU = number of physical CPU X number of cores per physical CPU X number of super threads
# check the number of physical CPU
Cat / proc/cpuinfo | grep "physical id" | sort | uniq | wc-l
# check the number of core in each physical CPU (i.e. the number of cores)
Cat / proc/cpuinfo | grep "cpu cores" | uniq
# check the number of logical CPU
Cat / proc/cpuinfo | grep "processor" | wc-l
# View CPU information (model)
Cat / proc/cpuinfo | grep name | cut-f2-d: | uniq-c
# View memory information
Cat / proc/meminfo
