For some reason /proc/cpuinfo is only displaying one core from a 16 core processor. However hwinfo --cpu shows the 16 cores. I have ACPI enable in the bios and I have cleared the noacpi tags out of the grub.cfg file.
I just installed Ubuntu and my CPU fan is constantly spinning at 1200 Mhz:
Code:
cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 23
model name : Intel(R) Core(TM)2 Duo CPU T6600 @ 2.
I'm using Intel i5-2430M processor which is a dual core processor, but the output of /proc/cpuinfo shows four cores. Why? Is is because of hyper-threading?
If yes, is there any way I can see the actual number of cores?
Also, how can I see the sizes of L1 and L2 caches?

Hello.
I have just updated lubuntu to 12.10 beta and during that process I found out that a PAE kernel seems to be mandatory these days. Kernel version "3.2.0-30-generic" was kept so I can work with this machine.
What can I do? Is there a ppa with another kernel flavor available?
I am extracting two pieces of information from the following file: /proc/cpuinfo, that I need to merge into one report.
The first command:
grep -i processor /proc/cpuinfo | awk '{print $1$2,$3}'
yields:
processor: 0
processor: 1
processor: 2
processor: 3
The second command:
grep -i "model name" /proc/cpuinfo | awk '{print $4, $5, $6, $7, " ", $8, $9, $10, $11}'
yields:
Intel(
This doesn't look right. Also, XP reports it as .999.
Hi,
I recently bought an AMD A6-3500 (triple core), one of AMD's new APU range but just discovered that ubuntu cannot see the third core, and system utilities like top and screenlets showing CPU usage show odd percentages like '124%' and '3%' when playing flash videos.
Output of
Code:
uname -a
is:
Code:
Linux bach 3.0.0-14-server #23-Ubuntu SMP Mon Nov 21 20:49:05 UTC 2011 x86_64
The kernel I'm running is Linux 3.2.0-0.bpo.3-486 i686.
Hi,
i need to optimize my.cnf.
