General :: Determine Socket From /proc/cpuinfo?
Jan 13, 2010Is there a simple way to determine the CPU socket from the output of /proc/cpuinfo. Determining the type of processor is simple enough, but the processor I have (Celeron) has two different possible sockets. The output of /proc/cpuinfo is:
processor : 0
vendor_id : GenuineIntel
cpu family : 15
[Code]...
I've looked on the Intel processor finder web site with appropriate filters, but the stepping values do not appear to match anything.
General :: Will Proc / Cpuinfo Gives CPU Info Per Core Or Per Thread?
Jul 18, 2011My CPU has 2 cores, so I can see two parts in /proc/cpuinfo.But, I want to know if CPUs that support Hyper-Threading (or similar tech), will /proc/cpuinfo give CPU info per core or per thread (or call it sibling)?I only know that Windows Task Manager will give CPU usage statistics per thread if the CPU supports HT.

Sep 2, 2011There is a computer with two "Xeon(R) CPU X5550 @ 2.67GHz" CPU. The Hyper-threading is enabled, so it looks like 16-core system, but really there is only 8 physical cores.
I know that when hyperthreading is enabled, each physical core is splitted into two virtual cores. I want to know, which pair of virtual cores shares a physical core and which are not. Or, how (in what order) will Linux enumerate HT-cores comparing to real cores. (enumerating is done for sched_setaffinity and taskset masks).
I have a dump of /proc/cpuinfo file from the system.
I think there are possible:
CPU0-CPU7 are not sharing phys. core. CPU8-CPU15 too. But sharing is in pairs CPU0+CPU8, CPU(i)+CPU(i+8) and so on. or CPU0+CPU1 are from single physical, CPU2+CPU3, CPU(2*i)+CPU(2*i+1). or exotic CPU0+CPU15 sharing, CPU1+CPU14 ... or random?
The hard moment in this case is that there are 2 physical dies of CPU (two sockets), and usual recommendation of using "physical id:" field can't help
The cpuinfo:
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 26

Fedora :: Kvm Shows (vmx) In /proc/cpuinfo But Can't Load Into Kernel?
May 13, 2011I have fedora 14 installed and wish to use/learn kvm. I installed via groupinstall the virtualization group. I see vmx in /proc/cpuinfo. but when I start virt-manager I get a message that kvm is not installed or cannot be leaded into the kernel (to make a long message short). I am at a loss here as to what to do. I run cat /proc/modules and see "kvm 257420 0 - Live 0xffffffffa022a000". also after running modprobe kvm I run [root@fed14 ~]# lsmod | grep -i kvmkvm 257420 0 and see kvm there.

General :: CPU Speed Stepping And Nice Values?
May 25, 2010My cpu is set via Gnome-power manager to automatically speedstep under demand....
the thing is i have a few nice level 19 processes running most the time that eat up all the idle time, this forces my clock speed up and as such makes the fan noisy and uses more power...
basically what i would like to do is to ignore process load with a nice over a certian level when determining weather to speed step.

General :: Trying To Understand Where Bootloaders Are Installed
Apr 28, 2011In the beginning there is MBR. MBR looks for the active partition and tranfers control to the VBR of the active partition. MBR is where grub may be installed. which allows the user to choose an OS(a VBR) I am not sure what the program in the VBR does,but it manages to loads the OS. What am I trying to do: Backup. I ma tired of losign my partitions my bootloaders. I want to backup them all! partitions/MBR /VBR everything short of creating an disk image.
My questions:
1. say the ubuntu partition is formatted, will grub still load? if not is there a bootloader that would?am I making sense? i hope so...
2. what exactly does the VBR contain ?
2. How do I go about backing up? The mbr and the partiton table are backed up with a simple dd command. Then what else needs to be backed ? VBR's of every partition?

General :: How To Grab Tricky Fields In A String
Mar 28, 2010I'm writing a script that picks out the time offset in a string, but am trying to figure out a way to print a field based on a match (likely needs to be regex).
Here are some sample fields:
09.900. Either add -12:-1: 0 to existing offset, or restart the slicer with no offset or with offset=00
09.900. Either add -12:-1:30 to existing offset, or restart the slicer with no offset or with offset=00
09.900. Either add -10: 0:-47 to existing offset, or restart the slicer with no offset or with offset=00
What I need would be "-12:-1: 0" from the first line, for example. I was just using "awk '{print $4}'" originally but because of the damn space in the 1st and 3rd lines by the 0, that doesn't work for me. How to grab those fields correctly for all cases?
General :: Scripting: Modifying SQL Fields Dynamically?
Feb 22, 2010I'm looking for a way to dynamically modify a fied in the SQL file.
Example,
INSERT INTO `TABLE` VALUES(1AADFDF,DFF33D,10023,SOMEDATA, SOMEDATA);
INSERT INTO `TABLE` VALUES(1AADFDF,DFF33D,10098,SOMEDATA, SOMEDATA);
[code]....
The third field in this SQL file is what needs to change to n+1
"10023" needs to change to "1"
"10098" needs to change to "2"
"10123" needs to change to "3"
"10983" needs to change to "4"
etc...
I tried with awk and sed, but since both require the usage of ' (single quote), my variable fails to get updated. I know i can use cut and recreate the sql statememnt, but i believe there should be easier way using sed or awk. Would anyone know of any creative way to get this to work in one-liner? This needs to be a part of the script preferable without making call to external file.

View 1 Replies View RelatedGeneral :: Unable To Model The Power Consumption Of Various Components
Aug 3, 2011I am working on a traffic surveillance project which performs various image processing tasks with a number of visual sensors and a computing platform. My basic task in the project is the power optimization/management. I am using a ZOTAC-IONITX computing platform (Intel ATOM CPU + NVIDIA ION GPU). The problems that I am currently facing are:
I am unable to model the power consumption of various components e.g., processor, GPU, hard drive, memory etc, since there seems to be no way to measure the power consumption of individual system components. Since I don't have a power consumption model, I cannot come up with a power optimization algorithm. I am currently working on Linux. Is there any way to measure/model the power consumption of individual system component?
I have already checked powertop. It doesn't tells the power (watts) consumed by a component (e.g., microprocessor). It just gives information about the power state the processor is in (However there is no way to change the power state by the user) and the processors that cause processor to wakeup.
