I have a web server with CentOS 5.8.
My hosting provider says that I have e6600 with 2.4GHZ.
I tried the following and I get different clock speeds each time.
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?
Output of /proc/cpuinfo: http://pastebin.ubuntu.com/1206427/
My box is using intel i7 with hyperthreading enabled. So it has 8 logical processors. I am confused about their numbering.
I checked the /proc/cpuinfo file, the processor id, core id, and siblings do not AT ALL give any information about the REAL topology of the processors (e.g., the processor ids range from 0 to 7, and all the core ids are 0).
Can anybody explain this to me?
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 am getting the following error message at boot:[ 2.859011] [drm:intel_lvds_enable] *ERROR* timed out waiting for panel to power onThe laptop is an HP DM4-3055DX.
How can I tell whether my processor has a particular feature? (64-bit instruction set, hardware-assisted virtualization, cryptographic accelerators, etc.) I know that the file /proc/cpuinfo contains this information, in the flags line, but what do all these cryptic abbreviations mean?
For example, given the following extract from /proc/cpuinfo, do I have a 64-bit CPU?
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
