一. CPU信息

1. AIX

1.查看CPU核心数：# pmcycles -m

# pmcycles -m
Cpu 0 runs at 1900 MHz
Cpu 1 runs at 1900 MHz
Cpu 2 runs at 1900 MHz
Cpu 3 runs at 1900 MHz

2.查看逻辑CPU个数# bindprocessor -q

# bindprocessor -q
The available processors are: 0 1 2 3

3.查看CPU物理个数：

方法一：# prtconf|grep Processors

# prtconf|grep Processors
Number Of Processors: 2

方法二：# lsdev -Cc processor

# lsdev -Cc processor
proc0 Available 00-00 Processor
proc2 Available 00-02 Processor

3.查看单个CPU信息：# lsattr -E -l proc0

# lsattr -E -l proc0
frequency 1900098000 Processor Speed False
smt_enabled true Processor SMT enabled False
smt_threads 2 Processor SMT threads False
state enable Processor state False
type PowerPC_POWER5 Processor type False

2.Linux

1.查看cpu核数

grep -c 'processor' /proc/cpuinfo

2.查询CPU个数：

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