Find CPU Speed and Memory Size on Solaris

As I’m writing my thesis I’m running tests on an old SMP Solaris machine. Obviously, I need to provide the specs of this machine in the paper so that the readers can see my results in context (ie why everything is taking forever. On linux I would just use lshw which is your ultimate hardware information goldmine. If you don’t have it on your system, go install it now. You will thank me later.

The ancient Solaris machine I was working with did not have it, so I was forced to find other ways of finding information such as CPU speed and memory size.

First you can try prtdiag – it will tell you detailed information about all your CPU’s and memory banks. Unfortunately it is in a weird directory that is not in your $path so you will need to run it with the absolute path:

/usr/platform/sun4u/sbin/prtdiag -v

If you just want information on the CPU’s you can also try:

psrinfo -v

Finally, to just get your total memory size do:

prtconf | grep Memory

There might be better ways to do this, but these worked for me. Craig will probably be able to add to this list or correct me. :)

    Almost . . .

    The path to prtdiag depends on the architecture of the system. The one you listed works on any Sun with a sun4u microprocessor. Use the following instead:
    /usr/platform/`/usr/bin/uname -i`/sbin/prtdiag -v

    Running this on a CoolThreads machine will yeild some interesting data:

    czar / 3% /usr/platform/`/usr/bin/uname -i`/sbin/prtdiag -v | more

    thanks for this post

    The

    /usr/platform/sun4u/sbin/prtdiag -v

    command was quite useful
