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 have intel celeron d 3.06ghz processor . Now I am using 32 bit Ubuntu and I wish to upgrade to 64 bit Ubuntu if my processor allow. My doubt is how to identify 64 bit processor with cat /proc/cpuinfo command. it shows
clflush size : 64
Does my processor support 64 bit OS ?
I've tried to decide processor affinity rule for my applications according to /proc/cpuinfo , My redhat Linux showes
processor : 0 to 47 , means server has 48 processor unit
physical id : 0 to 3 , means server has 4 cpu sockets
cpu cores : 6 , means each socket has 6 cores
siblings : 12 , means each core has 2 hyperthreads
So totally , this server has 4 * 6 * 2 = 4
I have a linux server that apparently has two Intel Xeon X5670.
/proc/cpuinfo shows 12 CPUs but dmidecode shows only one CPU and the other one is in the Unpopulated status like it is showing that this is other CPU is because of the hyper threading.
My server is a HP Proliant DL380 G7 and it can have up to two CPUs.
My question is if my server has one or two physical CPUs or if there is a settin
I have a Sony Vaio laptop (VGN-FZ140E) running Ubuntu Studio 9.10, kernel 2.6.31-20-generic-pae SMP i686. I've been noticing some performance issues and was checking to make sure that both cores were active when I came across a discrepancy with the CPU core frequencies. According to /proc/cpuinfo, one processor is running at 800 MHz and the other at 1801 MHz.
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:

can any one please clarify the difference between actual no of processors and CPU cores.
in my case i am having Intel Xeon® Processor E5620 as per intels product page: its having
# of Cores 4
# of Threads 8
and cat /proc/cpuinfo |grep processor|wc -l is showing 16
so what is this 16 showing here?.
I am planning to virtualize this machine with xen to 4 vms,each with 4 cpu.So
Hi,
Could you please Tell me the command to find the number of cores in red hat box?
I have tried cat cat /proc/cpuinfo | grep processor | wc -l command to find the number of processers.
But need to fond the number of cores.
Is there any difference between core and processor?
Please help on this.
Regards,
Vikas.
2x Xeon E5620 .
16 Cores altogether.
/proc/cpuinfo shows cache is only @ 4096kb
According to intel this should have 12MB of "smart cache".
Doing searched for E5620 and CPUinfo shows the correct number:
cache size : 12288 KB
However mine shows this:
processor : 15
v endor_id : GenuineIntel
cpu family : 6
model : 44
model name : Intel(R) Xeon(R) CPU
