Processors on DL380 G4

Hi all,

I have a DL380 G4 with Linux Red Hat AS and 2 processors.

when I ran the top command, I can visualize 4 processors.

Why I can see 4 processors when physically they are just 2 processors?

Thenks,
Toscanini

Re: Processors on DL380 G4

Two possibilities:
- Hyperthreadimg is enabled (by deafault) in BIOS, so your OS sees two logical processors per ceach physical CPU
- your CPUs are dual-core, hence 4 cores alltogeter

I guess the former scenario applies to your case.

Rgds.
