how to se all cpu's on superdome

[Simon Jespersen]

Hi
is it possible to se all cpu's on a superdome even though it has both vpart and npar configured.

best regards
Simon

Yes, it is viewable from the GSP.

Log on to the GSP and run PS on the cells.

[Torsten.]

After selecting the cells when running "ps", the result will look like this:

CPU Module Slot 0 1 2 3
Populated P P P P
Local 48V Good * * * *
Power Enabled * * * *
Power Good * * * *


(all 4 CPU modules are there in this cell)

[Torsten.]

Another tool to run:

parstatus

This will give you information about all the hardware across different nPars (and of course vPars):

...
Hardware Actual Deconf/ OK/ Cell Next Par
Location Usage Max Deconf Connected To Capable Boot Num
========== ============ ======= ========= =================== ======= ==== ===
cab0,cell0 Active Core 8/0/8 32.0/0.0 cab0,bay0,chassis0 yes yes 0
cab0,cell1 Active Core 4/0/8 16.0/0.0 cab0,bay0,chassis1 yes yes 1
cab0,cell2 Active Core 4/0/8 16.0/0.0 cab8,bay0,chassis0 yes yes 2
cab0,cell3 Active Core 6/0/8 32.0/0.0 cab8,bay0,chassis1 yes yes 3

Thanks for your replys, im not shure of how to drill down in all the info i get when i run those commands that you provided., i have to study for a litle while.

[Torsten.]

probably the best is "parstatus".

See this example:

cab0,cell0 Active Core 8/0/8 32.0/0.0 cab0,bay0,chassis0 yes yes 0

the part "8/0/8" is
"present_OK/deconfigured/max"

So calculate based on the first position (these are cores!) to get the total number.

In this example there are 11 dual-core CPU modules = 22 cores.

Hi Torsten!
Sorry i might be stupid but how do you calculate it,
cab0,cell0 Active Core 8/0/8 32.0/0.0 cab0,bay0,chassis0 yes yes 0

the part "8/0/8" is
"present_OK/deconfigured/max"

i can't se how you got 8/0/8 32.0/.0 to be 11 dual core cpu's

[Torsten.]

Sorry for confusion, it is this example:

cab0,cell0 Active Core 8/0/8 32.0/0.0 cab0,bay0,chassis0 yes yes 0
cab0,cell1 Active Core 4/0/8 16.0/0.0 cab0,bay0,chassis1 yes yes 1
cab0,cell2 Active Core 4/0/8 16.0/0.0 cab8,bay0,chassis0 yes yes 2
cab0,cell3 Active Core 6/0/8 32.0/0.0 cab8,bay0,chassis1 yes yes 3


8+4+4+6 = 22 cores

thank you very much, thats makes sense to me, the last thing i want to ask you guys, is how to dertermine wether it is single og dual core cpu's
Is there at cmd, that can be used from the shell of one of the partitions.

[Torsten.]

In case of Integrity systems, only Montecito CPUs are dual core (run "/usr/contrib/bin/machinfo" - the CPU family is 9000).
In case of PA-RISC all PA-8800 and PA-8900 are dual core.
