interpreting cpuinfo

Question

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 ?

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](http://ark.intel.com/products/27088/64-bit-Intel-Xeon-Processor-3_60-GHz-1M-Cache-800-MHz-FSB) cpu. What about `# of Threads` specified there. I see 1 thread, not two. – Kamil Z Aug 18 '11 at 09:07
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 09:32
You could try running `dmidecode`, its possible it will provide more detailed information. – Hubert Kario Aug 18 '11 at 09:34
Oh, and the Pentium IV has `siblings : 2` – Hubert Kario Aug 18 '11 at 09:44
