리눅스에서는 /proc/cpuinfo를 보면 된다. 들어있는 정보는 아래와 같다.
-----------------------------------------------------------------------------------------
processor : 7
vendor_id : GenuineIntel
cpu family : 6
model : 23
model name : Intel(R) Xeon(R) CPU E5450 @ 3.00GHz
stepping : 6
cpu MHz : 3000.089
cache size : 6144 KB
physical id : 1 -> 실제 cpu의 번호이다. 이걸로 cpu의 갯수를 알 수 있다.siblings : 4
core id : 7
cpu cores : 4 -> quad를 의미하며 1개의 cpu에 논리적으로 4개의 cpu의 역할을 한다.

IBM에 AIX OS에서는
* CPU확인은 lsdev -C |grep proc
proc0 Available 00-00 Processor
proc2 Available 00-02 Processor
proc4 Available 00-04 Processor
proc6 Available 00-06 Processor
proc8 Available 00-08 Processor
proc10 Available 00-10 Processor
proc12 Available 00-12 Processor
proc2 Available 00-02 Processor
proc4 Available 00-04 Processor
proc6 Available 00-06 Processor
proc8 Available 00-08 Processor
proc10 Available 00-10 Processor
proc12 Available 00-12 Processor
* CPU Hz확인은 lsattr -El proc0
frequency 2,301,696,000 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
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
* 메모리 확인은 lsattr -El sys0 -a realmem or svmon이다. 그런데 topas로 보는게 용의함
realmem 8388608 Amount of usable physical memory in Kbytes False
svmon
