Dual Xeons on DL360 with Linux RedHat 7.3

[Trevor Jennings]

Hello,

On our new DL360 server I noticed after installing RedHat 7.3 that the OS is reporting 4 cpus rather than 2. Anyone know why this may be the case and whether there would be anything to be concerned about?

[Mark Grant]

Are they prossibly dual core processors?. A dual core processor could well look like two processors to the OS.

Hi.

Mark is right it looks like you have 4 CPU's whan you in fact have two: check the dmesg command.

HTH,

Thats a very good question. The cpu's are 3.06Ghz Xeons with the 1Mb L3cache.

These processors are dual core which seems to fit in with what we see here

[Trevor Jennings]

Okay thanks for the replies. That does make sense with the hyper threading.

There are other reported cases of this happening in back Linux threads.

Are you using the smp kernel?

Yes, I am using the default 2.4.18-3smp kernel that comes with redhat 7.3.
