linux see cpu Number command
( one ) concept ① Physics CPU actual Server On slot in CPU number Physics cpu quantity , You can count non repeating ones physical id There are several ② logic CPU
/proc/cpuinfo Used to store cpu Hardware information The information contents are listed separately processor 0 –processor n Specifications . You need to pay attention here .
linux How to view cpu digit Linux see CPU Number of digits (32 position , still 64 position ) This can be achieved by the following command ： # query cup information , then grep Is search supported lmcat
/proc/cpuinfo | grep flags | grep ' lm ' | wc -l8# notes ： Result greater than 0, Description Support 64bit calculation .
linux How to check the card cpu Frequency of
stay linux see cpu The information steps are as follows ：
linux of cpu Information can be extracted from the file cpuinfo Caries reading Execute command : # cat /proc/cpuinfo
Generally seen processor It's a logical core . Its count is from 0 Started , For example, what you see here is 7, Then we usually say that this machine is 8 Nuclear , It's actually a logical core .
linux How to view with command CPU framework
see 386,686,x86_64 That's the message
get CPU Details of #cat /proc/cpuinfo cat /proc/cpuinfo Information in processor Logical processor id.
physical id Of physically encapsulated processors id. core id Of each core id. cpu cores Number of cores in processors in the same physical package .
siblings Processing in the same physical package
suse linux see cpu Dominant frequency command
see CPU information ：cat /proc/cpuinfo Other commands for viewing hardware information . View board information ：cat /proc/pci see PCI information ：lspci
( comparison cat /proc/pci More intuitive ) View memory information ：cat /proc/meminfo see USB equipment ：cat /proc/bus/usb/devices
View keyboard and mouse :cat /proc/bus
linux How much do you think cpu
cat /proc/cpuinfo Information in processor Logical processor id. physical id Of physically encapsulated processors id. core id
Of each core id. cpu cores Number of cores in processors in the same physical package . siblings Number of logical processors in processors in the same physical package .
