Montecito or Montvale processor

[Trojan36]

I need to add some CPU cores to my rx7640 server, but I forgot the type of CPU is currently in the rx7640. Is there a unix command I can use to let me know the type of CPU I currently have? I just know that is the 1.6GHz processor. The Montecito and the Montvale is not mixable even on a separate cell board, is that correct? Thx in advance.

Use

# machinfo

Example:

# /usr/contrib/bin/machinfo
CPU info:
32 Intel(R) Itanium 2 9000 series processors (1.6 GHz, 18 MB)
533 MT/s bus, CPU version C2
64 logical processors (2 per socket)

...
or

# machinfo
CPU info:
2 Intel(R) Itanium 2 9100 series processors (1.67 GHz, 18 MB)
666 MT/s bus, CPU version A1
4 logical processors (2 per socket)

...

9000 series processor = Montecito
9100 series processor = Montvale

Forgot to say the only system where you can mix different CPUs in different nPars under special circumstances is the superdome server.
