32-Bit or 64 Bit processor?

Daniel Navarro — Mon, 18 Feb 2002 18:10:52 GMT

How can I tell what processor I am using? I have
used the getconf command and it returns 32, but
others in my group are arguing that it is actually a
64-Bit processor running at 32-Bit. How can I verfiy this?

TIA,
Daniel N.

firstly, which model 900 are you using, this will tell us whether it can run 64bit, or even 32 bit.
Secondly, I believe you run the command getconf KERNEL_BITS
If it returns 32, you are running 32bit OS, if 64, then it is 64bit OS.

Hi:

# getconf KERNEL_BITS

...shows what kernel "bitness" you are running.

# getconf HW_CPU_SUPP_BITS

...returns what you "bitness" you *can* run.

Hi Daniel,

For finding out processor speed, use this command:

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

Also the getconf KERNEL_BITS will report the version (32 or 64bit) of your operating system, not your CPU speed

Hi,
Sometimes your print_manifest command can tell you if you are running 32-bit or 64-bit .. (if you have ignite loaded)

(you need to be root to execute this command)

Hi Daniel,

To find out if the kernel is 32 or 64 bits try this,

On 32bit systems you will get following:
# getconf KERNEL_BITS
32

On 64bit systems you will got following:
# getconf KERNEL_BITS
64

to find out if the cpu supports 32/64 bit,

start sam
goto Performance Monitors -> System Properties -> Processor
verify Kernel Width Support:

The following summarizes the HP 9000 Server implementations:

32-Bit Only: D, E, G, H, and I-class, K-class (PA7 x 00), T500, and T520.

32/64-Bit: K-class (PA8x00), and T600,

64-Bit Only:V2200, N-Class, L-Class

Hope this helps.

Hi,

I don't think getconf KERNEL_BITS will work on 10.20... It works for sure on 11.00 ...

You are correct

# getconf KERNEL_BITS

does not work on 10.20, but if you are running 10.20 you are running a 32-bit OS anyway, so it's a moot point.
