I have to figure out what kind of cpu my HS20 have. Its /proc/cpuinfo output is below. Is that mean It has two IntelXeon units with two cores each ?

processor       : 0

Yes, you have 2 dual core processors which is the maximum configuration for a HS20.

You have two physical processors:

physical id     : 0
physical id     : 6

Each with two threads:

runqueue        : 0
siblings        : 2
...
runqueue        : 2
siblings        : 2

In that case, this is probably this cpu. What about # of Threads specified there. I see 1 thread, not two. – Kamil Z Aug 18 '11 at 9:07
I'm not certain about Hyper Threading, but I'm sure that those are two cpus that either have two cores or have HT. Dual cores are shown as cpu cores : 2 and core id : 0, core id : 1 with siblings : 2 on my single Core 2 Duo (with Linux 3.0) and Pentium4 has core id : 0 for both threads and cpu cores : 1 on Linux 2.6.26. – Hubert Kario Aug 18 '11 at 9:32
You could try running dmidecode, its possible it will provide more detailed information. – Hubert Kario Aug 18 '11 at 9:34
Oh, and the Pentium IV has siblings : 2 – Hubert Kario Aug 18 '11 at 9:44
