Processor Speed

Hi,

1. How can I check/identify my systems Processor speed?

2. How can I check/identify how many processor/s do I have in my system?

Thanks...

Hi,
Check the following

http://www1.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000062972855

Use top to get the no. of processors.

and

echo itick_per_usec/D | adb -k /stand/vmunix dev/mem

to get the processor speed

Srini.

you can also do this in sam.

performance monitors -> system properties.

look at the processor tab, which should be the one that comes up anyways.

Processor speed
echo itick_per_usec/D | adb -k /stand/vmunix dev/mem

You can get the number of processes a few ways.

top
glance

or using stm, will get you a little more info.

# "seclass qualifier cpu;info;wait;infolog" | cstm

If I can spell and type at the same time:

# "echo selclass qualifier cpu;info;wait;infolog" | cstm

This will actually give you both, divide the processor speed by 1,000,000

I must be having a brain day.....

Another way to see the number of processors is:

# echo "runningprocs/D" | adb -k /stand/vmunix /dev/kmem

Guys,

Just to summarize...

1. 1. How can I check/identify my systems Processor speed?

# echo itick_per_usec/D | adb -k /stand/vmunix dev/mem

2. How can I check/identify how many processor/s do I have in my system?

# echo "runningprocs/D" | adb -k /stand/vmunix /dev/kmem

BTW, with command #2 I have verified that I have 2 working CPUs. But when I issued command #1 it only gives me 1 processor speed. Why?

Hi,

You only get one processor speed reported because all the CPUs must run at the same speed in an HP9000.

We have a n-class with 360mhz processors.

We were told by HP that we could install 440mhz processors in the same machine but they would operate at 360mhz...

Is this not the case?

Hi,

Multiple processor on the same system are running at the same speed.

Hope this helps.

Hi,

You can also use,

db001:/etc# ioscan -fnkC processor
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
processor 0 160 processor CLAIMED PROCESSOR Processor
processor 1 166 processor CLAIMED PROCESSOR Processor

Hope it helps,

Robert-Jan.

You can actually get clock rate information for each processor with the pstat_getprocessor function.
That still reports the same speed for every processor. Here is a small example program.

#include
#include
#include
#include
int main(int argc, char *argv[])
{
struct pst_processor st;
int id;
for (id=0; pstat_getprocessor(&st, sizeof(st), (size_t)1, id)==1; id++) {
printf("processor %d- %d clock cycles per second\n",
id, st.psp_iticksperclktick * sysconf(_SC_CLK_TCK));
}
return 0;
}

ummm, I read about the stm that was just posted. I got into it, and can't get out! I know, I know...what a sad, sad post. Can somebody help me?

Thanks,

Hi Mary,

Don't be hard on yourself, we all have days like this.

Not sure whether you're sitting at a
cstm>
prompt or not.
If so just type quit & 2 returns to get out.
If you went into cstm via the echo/pipe routine a ctrl-C should get you out. If that doesn't do it try the delete key. If that doesn't do it try the ctrl-backslash.

Rgds,
Jeff
