# 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 (that is, number of cores) cat / proc/cpuinfo in each physical CPU | grep "cpu cores" | uniq

Check the number of logical CPU cat / proc/cpuinfo | grep "processor" | wc-l

View CPU information (model number)

Cat / proc/cpuinfo | grep name | cut-f2-d: | uniq-c

View memory information
