如何查看IBM 小型机有多少个物理CPU

Question

如题所述

Answer 1

1、检查系统中的物理cpu和逻辑cpu的个数
# smtctl
This system is SMT capable.
This system supports up to 2 SMT threads per processor.
SMT is currently enabled. //说明开启了SMT
SMT boot mode is not set.
SMT threads are bound to the same physical processor.

proc0 has 2 SMT threads.
Bind processor 0 is bound with proc0
Bind processor 1 is bound with proc0

proc2 has 2 SMT threads.
Bind processor 2 is bound with proc2
Bind processor 3 is bound with proc2

proc4 has 2 SMT threads.
Bind processor 4 is bound with proc4
Bind processor 5 is bound with proc4

proc6 has 2 SMT threads.
Bind processor 6 is bound with proc6
Bind processor 7 is bound with proc6
//说明4个物理CPU对应8个逻辑CPU

2、# lsdev -Cc processor
proc0 Available 00-00 Processor
proc2 Available 00-02 Processor
proc4 Available 00-04 Processor
proc6 Available 00-06 Processor

# lscfg -vp|grep proc
proc0 Processor
proc2 Processor
proc4 Processor
proc6 Processor

# prtconf|more
System Model: IBM,9117-570
Machine Serial Number: 109161D
Processor Type: PowerPC_POWER5
Processor Implementation Mode: POWER 5
Processor Version: PV_5
Number Of Processors: 4
//4个物理CPU

3、查看逻辑CPU，8C
# pmcycles -m
CPU 0 runs at 1654 MHz
CPU 1 runs at 1654 MHz
CPU 2 runs at 1654 MHz
CPU 3 runs at 1654 MHz
CPU 4 runs at 1654 MHz
CPU 5 runs at 1654 MHz
CPU 6 runs at 1654 MHz
CPU 7 runs at 1654 MHz

Answer 2

打开任务管理器，有个性能窗口，显示一个就是几个CPU
