I am running the command show cpu/full on OpenVMS VAX 7.2 and getting this information:-
STAR72, a MicroVAX 3100-90
Multiprocessing is DISABLED. Uniprocessing synchronization image loaded.
PRIMARY CPU = 00
CPU 00 is in RUN state
Current Process: DISCOVERY PID = 00001CAD
Capabilities of this CPU:
PRIMARY QUORUM RUN
Processes which can only execute on this CPU:
*** None ***
I want to find the Processor Clock Speed and Model information.
Is there any way I can do that? Any other command?
Thanks,
Vineet

Re: Finding processor information on OpenVMS VAX
See HELP LEXICAL for some of that information.
Fortunately folks have already put many procedures together to get and format much of that information in various ways, including as HTML output which can be served to any browser if you have a web server or a Pathworks or other shared file system area.
Some are at http://dcl.OpenVMS.org and others are in the various freeware collections, starting with http://h71000.www7.hp.com/openvms/freeware/ and http://mvb.saic.com/
For the published clockspeed, once you have nailed down the exact model (and I think the MV3100-90 may be it; I don't recall if there were any variants), then I would do a Google or similar search for the specifications.

Re: Finding processor information on OpenVMS VAX
Why does the speed matter?
For completeness, it is worth noting that emulated or simulated environments often report the identification of a real machine. Thus, performance, particularly in terms of CPU speed, may differ significantly from that of the reported processor.
One can use Google to determine the measured performance of a MicroVAX 3100-90, if the machine is indeed what is being reported.

Re: Finding processor information on OpenVMS VAX
As for the answer to your question on clock speed, there's always Google and Wikipedia.
http://en.wikipedia.org/wiki/MicroVAX
The answer to your clock speed question is included in Wikipedia, BTW. 72 MHz.
VAX systems generally do not have machine-readable serial numbers. (Some do have something similar, but you can set the value reported to the operating system to most anything you want.)

Re: Finding processor information on OpenVMS VAX
Thanks for your answers. I was wondering why don't we get information from show cpu/full on VAX because I am getting a whole lot of information when I run this command on a machine running OpenVMS Alpha. This is the output on Alpha:-

SolutionThe difference between VAX and Alpha reflects differences in the architeture. You can get more information directly from an Alpha chip than a VAX, so more & different information can be displayed by the SHOW CPU command.
In particular there is no mechanism for determining the clock speed from a VAX chip itself (short of deducing it by timing the execution of a known sequence of instructions).
You'll see a different set of information displayed on an I64 system.
Since the last VAX chips were produced last century, and they literally smashed the dies, this isn't something that will ever change!
