I am using the standalone k10temp temperature sensor but it doesn't give the actual temperature of the cpu, just some "bogus" temp value that isn't very useful.Does anyone know how you can calculate the real temperature from this reading?
View 3 RepliesI have a notebook with AMD Athlon 64 QL-62 2 cores CPU. Normally the temperature is 50-52 Celsius in idle but with Ubuntu 10.04 beta 2 idle temp is 60 Celsius. /proc/cpuinfo shows both cores on 1GHz which is good but still temp is higher than usual. I tried to find solution using Google but I didn't find anything.

This is a Linux Box.
Here is the output and I need to know how many CPUs we have and how many cores per CPU.
When I was using Virtual Box in Windows 7, I could choose how many CPU cores to assign to the guest OS. Now I'm using Linux, and when I installed Virtual Box, I couldn't find that option. System Monitor shows that when the VM is busy only one CPU core goes to 100% while the rest are near 0%. How can I make Virtual Box in Linux use multiple CPU cores?

I am new to the forum and new to Linux.
I am trying to explore if Linux can be run on a multicore platform when the max frequency of one the cores is less than the others.
please give me some pointers or let me know if you have tried such HW configuration.
There 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
model name : Intel(R) Xeon(R) CPU X5550 @ 2.67GHz

Trying to install Ubuntu from CD. I choose my language and hit Install and come to a black screen with the Ubuntu symbol glowing (loading everything I assume) and after a minute my screen fills up with messages saying my CPU Temperature is 99 (gets progressively higher) degrees. Is there something else I need to do before installing?
I have windows installed on my C drive and I'm planning on installing Linux on another blank drive. The Ubuntu version is the newest one (9.10) I think.

View 3 Replies View RelatedCurrently my CPU temperature as measured by lm-sensors increases by 1-2 C upto 4-5 C when I start a new process - like a video, music, etc. The change takes place in less than a second. Is this normal or should the change be happening more slowly?
If it is indeed happening too rapidly, what could be the likely causes?
I'm running Ubuntu 10.04 with Core i5 430M.
Edit: I should add that these are temperatures from an HP laptop (dm4t).
It's from my /var/log/messages

I checked the temps with ln_sensors, KVM and DC temps, everything is running great. I didn't get any shutdown in the meantime. I basically need a way to disable those warnings but reboot is out of question, means no BIOS. Hope its possible to disable it from the console itself, with blacklistinh some kernel module(s) or something like that.
I have a Dell Precision M4500, Intel Core i5 CPU, running Linux (Ubuntu Lucid), and would like to keep an eye on CPU temperature. I've tried lm-sensors: sensors-detect didn't find any sensors; following its hint ("This is relatively common on laptops, where thermal management is handled by ACPI rather than the OS.") I tried acpi -V but got nothing thermal. The Gnome panel applet "Hardware Sensors Monitor" reports on GPU temperature but nothing else.

View 3 Replies View RelatedI'm trying to monitor the temperature of my GPUs (multiple ATI 5970) in my computation cluster. Problem is that the aticonfig tool does not work in headless mode
# /usr/bin/aticonfig --od-gettemperature No protocol specified ERROR - X needs to be running to perform ATI Overdrive(TM) commands
and even worse if I try to run aticonfig with my monitoring user (munin) it will ask to be executed as root. Is there a simple way to read the temperature of the GPUs without having to resort to X?
I'm thinking of designing a software that may need to change the current user to a normal user if run as root. But from what i've read, you can still switch back to root if you were root in the first place (meaning, the real UID is 0). I'd like to make this impossible. I think the solution is forking but i'd like you to confirm this.
My question is, does the real UID of the children is the effective UID of the parent at the time the fork is done? My manual lists what's inherited from the parent but doesn't states this. I'd like an answer about Linux kernel and about Unices in general (i'd like to make it at least POSIX-portable)
about VIP (Virtual IP) and real IP address used for load balancing. How they work and how to configure real IP.
View 1 Replies View Relatedknow of a way in Linux to have a virtual ethernet (e.g., eth0:1) appear as a "real" ethernet (eth1)? I ask because I have an old Shuttle box that only has one mobo ethernet and no way to add more. I'd like to use it in my Oracle RAC lab, but RAC requires two physical ethernets. You can't fool it with eth0 and eth0:1. RAC won't setup correctly if there's only one eth adapter, so I'm wondering if there is a way to fake two ethernets. I do not care about performance or reliability - it's my home lab. I fully realize that this violates every principle of HA, but I'm just using it to study. Worst case, I can get a USB dongle ethernet adapter, but I'd prefer to avoid the cost if possible.
View 3 Replies View RelatedI've got the following problem:
1. I start two bash windows
2. In one of them I start a script test1:
Code:
This script puts a natural number 5 times a second.
3. Then in the second bash window I type (as root):
Code:
The script test2 looks as follows:
Code:
While true; do
true;
done
During the following 15 seconds test2 is the process with the highest real-time priority. As far as I know the script doesn't perform any system calls so it shouldn't be suspended even for a minimal timeslice. My question is: why the process test1 manages to put a few numbers on the screen before test2 stops. I thought that test2 would exclusivly own the processor for 15 seconds.
