Gianluca,

There is a Red Hat Knowledgebase article titled "How do I determine if my x86-compatible Intel system is multi-processor, multi-core or supports hyperthreading?" that I think you will find useful.  It states:

  To determine whether a system is multi-processor, multi-core, has
  hyperthreading or supports a combination of the three, look at the
  physical id, siblings, core id and cpu cores values in /proc/cpuinfo
  on Red Hat Enterprise Linux 4 or on Red Hat Enterprise Linux 5 while
  running a non-Xen kernel.

It provides several examples that you could use to write and test your script.

Here's the link: http://kbase.redhat.com/faq/docs/DOC-7715
