how to identify processor?

Costin Apostol — Mon, 13 Nov 2006 07:32:22 GMT

Hi,

How can I find out in hpux what processor do I have?

I can only find my machine type:
bash-2.03# model
9000/785/B1000

How do I get the processor type? I need something like PA8500...

It does not matter if it is C++ code or shell command...

Thanks,
Costin

Shalom,

model command.

Better yet, http://docs.hp.com

It says exactly what processor is in your system.

I really need a C++ code or shell command...

Thanks

Hi,

echo "selclass type proc;info;wait;infolog" | cstm

This should help you i think

Thanks,

C ostin,
please read the info in the link I provided.

In Procura's answer are a number of ways of getting the info:

echo "selclass qualifier cpu;infolog" | /usr/sbin/cstm | grep "CPU Module"

Try this:

MODEL=$(grep -i $(model | tr "/" " " \
| awk '{print $NF}') \
/usr/sam/lib/mo/sched.models \
| awk '{print $NF}')
echo $MODEL

Sorry, none worked :(

1. /usr/sam/lib/mo/sched.models does not contain B1000 on my machine.

2. cstm, mstm, xstm do not exist on my machine.

Do you think I have any chance to get the information I need?

bash-2.03# uname -a
HP-UX Janus B.11.00 U 9000/785 2014840735 unlimited-user license

bash-2.03# model
9000/785/B1000

Hi,

If there is now way to find it , why dont you hardcode it in your program.

9000/785/B1000 has the following processor
PA 8500 processor at 300MHz

Thanks,
siva

Re: how to identify processor?

Pete Randall — Mon, 13 Nov 2006 08:22:24 GMT

Well, I can tell you that your B1000 has a PA-8500 processor that runs at either 300 or 400 Mhz, if that helps.

Re: how to identify processor?

Peter Godron — Mon, 13 Nov 2006 08:23:01 GMT

Costin,
if it helps (from my machine):
$ grep B1000 /usr/sam/lib/mo/sched.models
B1000 2.0 PA8500

which cstm
/usr/sbin/cstm

I would suggest:
1. you load the cstm etc tools.
2. Update to 11.11 ,as 11.00 support ends 31/12/06

Re: how to identify processor?

Costin Apostol — Mon, 13 Nov 2006 08:27:08 GMT

The only way to find my information seems to be

bash-2.03# model
9000/785/B1000

bash-2.03# cat /usr/sam/lib/mo/sched.models | grep 785
785 2.0 PA8500

But can I trust this information?
In http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=558731
i find that:

d3:/wrk 105 > model
9000/800/D390
d3:/wrk 105 > grep -i d390 /opt/langtools/lib/sched.models
D390 2.0 PA8200
d3:/wrk 106 > grep -i d390 /usr/sam/lib/mo/sched.models
D390 2.0 PA8000
d3:/wrk 107 > echo "selclass qualifier cpu;info;wait;infolog" | /usr/sbin/cstm | grep "CPU Module"
PA 8200 CPU Module 5.1

Diffent commands, different values. Who do I trust?

The program will run on various machines, not only mine, and should give accurate results.

H.Merijn Brand (procura — Mon, 13 Nov 2006 08:57:49 GMT

did you try my script (1) that incorporates all the tests?
I have explained most of it in the FAQ (2)

1: http://mirrors.develooper.com/hpux/ux
2: http://mirrors.develooper.com/hpux/faq.html

# ux
a5 HP-UX 11.00/64 U 9000/800/A500-7X/64 PA8700/750(2) pa-2.0 2048 Mb

And when you're in doubt, the cstm command gives more reliable info the the grep from the static files. The above mentioned script prefers the files over the command, as that is both faster and never needs su permissions.

If you have the perl module Unix::Processors installed, try this:

# perl -MUnix::Processors -le'print join"\t",$_->id,$_->state,$_->type,$_->clock for @{Unix::Processors->new()->processors}'
0 online HP PA-RISC 2.0 750
1 online HP PA-RISC 2.0 750

but as you see, that won't give you the *exact* type.

perl also supports syscall ()'s, and in the "ux" script on line 58 and on, you see how that can be used to call syscall (239, ...) which is the SYS_pstat call, and the second argument being 10 is the PSTAT_PROCESSOR request, /usr/include/sys/pstat.h will show you more.

to get all your device info you can run this
as root

echo "selclass qualifier all;info;wait;infolog" | cstm | tee -a device.log

(It includes the model command)

And look for the cpu part in your device.log

Oops forgot to upload the output file:
The section you need to look for
in device.log

Re: how to identify processor?

H.Merijn Brand (procura — Mon, 13 Nov 2006 09:33:02 GMT

You can get the *exact* model with this C program snippet, but (for now) only as a code, not as a CPU type string ...

--8<--- xx.c
#include
#include

int main (int argc, char *argv[])
{
long sc = sysconf (_SC_CPU_CHIP_TYPE);
printf ("sysconf (%d CPU_CHIP_TYPE) = %ld\n", _SC_CPU_CHIP_TYPE, sc);
return (errno);
} /* main */
-->8---

Above code is unsupported on HP-UX 10.20

# cc +DD64 -O -o xx xx.c
# ./xx
sysconf (10023 CPU_CHIP_TYPE) = 616
#

Local tests here reveal:

PA8500 : 552 (0x00000228)
PA8700 : 616 (0x00000268)
PA8800 : 644 (0x00000284)
Itanium2 : 520225284 (0x1F020204)

Re: how to identify processor?

H.Merijn Brand (procura — Mon, 13 Nov 2006 13:33:06 GMT

That C snippet is (of course :) :) also doable from the command line

# getconf CPU_CHIP_TYPE
616

On 10.20 you still get
getconf CPU_CHIP_TYPE: Invalid argument

http://www.openpa.net/cpu.html#table lists the hardware combo's, but not those values.

That made me google on CPU_CHIP_TYPE, and though rather dated, still interesting:
http://unix.derkeiler.com/Mailing-Lists/HP-UX-Admin/2003-04/0003.html

And a useful reference to some older discussion here, so I don't need to repeat myself:
http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=21381

Now, 'man confstr', which should yield the string representation of the code found by getconf (), is wrong (all _SC_'s written as _CS_), but that aside, it still returns zilch:

--8<---
#include
#include
#include

extern void *calloc (size_t, int);

int main (int argc, char *argv[])
{
size_t l;
long sc = sysconf (_SC_CPU_CHIP_TYPE);
char *cs = calloc (80, 1);

l = confstr (_SC_CPU_CHIP_TYPE, cs, 80);
printf ("sysconf (%d CPU_CHIP_TYPE) = 0x%08lx (%12ld) '%s' (%d)\n",
_SC_CPU_CHIP_TYPE, sc, sc, cs, l);
return (errno);
} /* main */
-->8---

/tmp 111 > ./xx
sysconf (10023 CPU_CHIP_TYPE) = 0x00000268 ( 616) '' (0)
Exit 22

Another interesting snippet from http://www.unixguide.net/scripts/stats151
--8<---
# plan A (getconf CPU_CHIP_TYPE)
##################################
if [ "$OSVER" -ge 1100 ]; then
typeset -i2 bin

Since all methods you suggested to me use dictionaries, I decided to use my own dictionary, based on `model` output and http://hwdb.parisc-linux.org/.

Using sched.models is having the dictionary at user host.
Using cstm is imposible since it is not on every machine.
Using `getconf CPU_CHIP_TYPE` is still a dictionay method and it happens not to be too accurate.
