Processor speed

[Ken Lee_1]

Can anyone tell me on how to check the processor speed instead of using "model"? I need to know the EXACT clock speed of the processor.

[Edward Alfert_2 · Accepted solution]

Per HP document on hp-ux 11.00:

To determine processor speed, use one of these methods:

- Option 1. Use this command:

echo "itick_per_usec/D" | adb /stand/vmunix /dev/kmem
itick_per_usec:
itick_per_usec: 60

- Option 2. Use SAM:

Sam -> Performance -&qt; Performance Monitors->
System Properties

clock speed = 60 MHz

Hi,

If you have STM installed on your system, you can get the info you are looking for easily.

Run and info on processor.

for that use stm in
xstm --> Graphical mode
mstm --> Character terminal mode
cstm --> Command line mode.

do "man cstm" or like that for mode info. STM is part of diag tools on the support plus CD.

Hope this helps.

thanks

Hi,
Use these commands:

- The model command shows that your system is a K220.

- The 'more /usr/lib/sched.models' command shows that the CPU
is a PA7200.

- This command will show the CPU speed:

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



Thanks

You can get processor speed from a program by calling pstat_getprocessor and sysconf. See the attached example.

[Ian P. Springer]

The below C program will print the first CPU's speed in MHz. It can be run by any user:

/* cpuspeed.c - To compile: cc +DAportable -o cpuspeed cpuspeed.c */
#include
#include
#include
#include
#include
#define CPU_ID 0
#define HZ_PER_MHZ 1000000
main()
{
struct pst_processor pst;
union pstun pu;

pu.pst_processor = &pst;
pstat( PSTAT_PROCESSOR, pu, (size_t)sizeof(pst), (size_t)1, CPU_ID);
printf( "%d MHz\n",
(int)((double)pst.psp_iticksperclktick * sysconf( _SC_CLK_TCK ) / HZ_P
ER_MHZ) );
}

Here's a script (hpmem) I use:

# Taken from the HP/UniGraphics FAQ
# You must be ROOT to execute this since it uses adb to
# examine the running kernel
