How to find exact number of Physical processors in HP Itanium

I am using HPUX11iv2, Itanium. Please give me the command to find
1. Physical and logical number of processors
2. Is multiThreaded enabled?
3. How many cores?

Shalom,

1-mstm,cstm, or xstm will identify the number of processors. You could also look in the box.

2-Always enabled.

3-Cores can be found from the answers to item 1. top normally shows number of cpus which corresponds to number of Cores.

Re: How to find exact number of Physical processors in HP Itanium

Hi,

1. use
/usr/contrib/bin/machinfo

example:
# /usr/contrib/bin/machinfo
CPU info:
32 Intel(R) Itanium 2 9000 series processors (1.6 GHz, 18 MB)
533 MT/s bus, CPU version C2
64 logical processors (2 per socket)

Memory: 523770 MB (511.49 GB)
...

2) No, 11.23 cannot work with HT enabled - only 11.31 can

3) see 1)


Hope this helps!
Regards
Torsten.

Re: How to find exact number of Physical processors in HP Itanium

Hello,

Answer to question 2:

For HP-UX 11.31 and above, in regards to
hyper-threading:

getconf _SC_HT_CAPABLE
getconf _SC_HT_ENABLED

And one more important note: Integrity VM
software cannot be started when
hyper-threading is enabled.

All these tests are part of my OAT script
for HP-UX :)

Re: How to find exact number of Physical processors in HP Itanium

I forgot one more command:

# setboot
Primary bootpath : 0/0/1/1/0.12.0
HA Alternate bootpath : 0/0/0/1/0
Alternate bootpath : 0/0/0/1/1
Autoboot is ON (enabled)
Hyperthreading : ON
...

Hi,

machinfo or dmesg | grep -v pro
or from cstm you can find the processor information.
