Ubuntu :: Support For 6 Core CPUs?
May 9, 2010I have just purchased an AMD Phenom II 1055T 6 Core CPU to replace my aging CPU. The problem is only 1 core is visible to Ubuntu, Does it actually support 6 cores?

Feb 20, 2011My setup:
HP XW8200
2x 3600MHz Xeon CPUs
4GB RAM
Quadro FX3800 PCIe graphics
Dual boot Ubuntu 10.10 32bit (primary use) and XP (gaming use only)
The issue I have is that the CPUs seem to run at 100% constantly in Ubuntu meaning that the CPU fans are constantly at high. This makes the machine sound like a wind tunnel!
It is nice and quiet in XP.
I installed GKrellM monitor which is what is telling me about the 100% CPU useage.
Would using the 64bit Ubuntu make any difference? (dont really want to reinstall tbh)

Ubuntu :: 10.04 Recognizes Two CPUs And Two Cores On Four Core CPU
Jun 23, 2010I'm using Ubuntu 10.04 x64, and I have an AMD Phenom 2 x4 940 CPU. First I have to underline that four cores worked perfectly in previous versions of Ubuntu as well as Windows.
When looking at system monitor it tells me that I have two CPUs/Cores, it should be four.
This is the output of CPU info:
Code:
processor: 0

Ubuntu :: 32 Bit And 2 X 1.66GHz Atom D510 CPUs
Jul 28, 2010I'm buying a new fanless desktop unit with 2 x 1.66GHz Intel Atom D510 CPUs. The vendor calls these a '64-bit processor'. But the unit has just 4Gb of memory and I don't want the fuss of 64-bit for the basic stuff I do. So I asked them to load Lucid-32.
Will the processors work with 32-bit?
The vendor tells me 32-bit won't make full use of the 4GB, only three and a half, but all else will be fine. So they'll load 32 and I'll try a live DVD of 64 in my own time. But I thought 32 bit was fine up to and including 4GB of memory?
Ubuntu Servers :: 10.04 I7 980x Not Showing 12 CPUs?

View 1 Replies View RelatedFedora :: CPUs Are Running About 60%?
Feb 13, 2011I've got some weird stuff going on with my F14 setup, I seem to be getting loads of CPU activity with nothing happening! Both CPUs are running about 60% as soon as I log in to my normal account. If I log into another account it drops to about 15%. Sometimes when I log out I get a message saying that 'an unknown process' is still running. Looking at processes it is not apparent what is causing this as nothing is using that much CPU. It does show some processes with no name, which seem to come and go and change ID. The only things I've installed recently are dropbox and myth tv. I've removed dropbox but no change. how I can find out where my CPU time is going!
View 3 Replies View RelatedUbuntu Multimedia :: Use Of Multiple CPUs During 1080p Playback?
Apr 21, 2010I have a high resolution file (1080p) encoded with H.264 and when I play it back, it lags at certain parts (and enough parts to destroy the job of watching the video).
I don't think that my computer is that crappy and it has been able to play many H.264 encoded files with high resolution - so there is always a possibility that this file is just encoded poorly (lacking a better computer, I cannot test).
For information, I'm running Ubuntu 9.10 64 bit. I have a Intel Core2 Quad CPU Q9550 (@2.83 GHz). I have 8 GB of RAM (forgot the speed off the top of my head). And a Nvidia GeForce GTX 280 (1 GB of memory).
During the playback, the RAM is far from being completely used; however, it seems that one (and only one) of the cores of my CPU becomes saturated at 100% precisely at the moments in which the file lags. When the CPU utilization is below 100%, there is smooth playback.
My question is - is it possible to use all four cores during playback, or is such a process not capable of easy parallel processing.
Another side question is, how can I be sure that my GPU is being used in the decoding process - or is that also being under-utilized?
Red Hat :: Centos 5.3 - 2 CPUs Are Missing On AMD Phenom II X4
Mar 12, 2010Not so long time ago I have installed Centos 5.3 on my AMD Phenom II X4 server (I am hosting game servers on it). Only today I noticed, that cpuinfo shows me only two CPUs. I watched for the info in the dmesg and found there that the system boots up only 2CPUs.
Here is some info from the dmesg:

Ubuntu :: 1 Of 2 CPUs Always Stuck At 100% Acer Asprire 5738G Dual Core?
May 1, 2010I have fresh install of Ubuntu 10.04 LTS Added Wine from Software Center but have no any Win apps loaded or running yet. I have also enabled visual Effects and the system installed and enabled NVidia's driver for the video-card after which the picture quality improved.
Here is the screen of my CPU monitor (sorry labels arre in Russian but the charts are quite intuitive) As you can see this 100% load "jumps" from one core to another periodically. On the Processes tab there is nothing fancy:
Less than 10% processes load. I have tried to play with CPU Clock Gnome widget, it doesn't really change the picture whether I use MAX CPU clock of 2Ghz or reduced power-saving 1,2 GHz. I have found couple similar cases on forum but see no solution so far.BTW, I have already launched the update manager and currently Ubuntu does not offer any new updates.

View 5 Replies View RelatedGeneral :: Determine The Number Of Physical CPUs Under Both Windows?
Sep 9, 2010When running cat /proc/cpuinfo under Linux, a variety information is kicked-back. For example:
> cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 15
model name : Intel(R) Xeon(R) CPU 5130 @ 2.00GHz
[Code]...
First, what does all of that actually mean? I see I have a processor 0 and processor 1. Does that mean Linux is reporting both cores of the CPU, or, since it is a VM, the two that I happen to have right now (even if they're on physically different CPUs)?
Second, how can I get a similar information dump form the command line in Windows? Third, is there a way using either platform to determine the number of physical CPUs versus total CPU cores?
CentOS 5 Hardware :: Maximum Number Of CPUs Supported

The question I have regarding the specified information ("64/255" logical CPUs) is, which number means what. Does this mean 64 real CPUs with a maximum of 255 cores/hyperthreaded CPUs or something similar or totally different?

View 9 Replies View RelatedGeneral :: Sun Grid Engine - Reserve Multiple Cpus On Hosts
Mar 14, 2011I am somewhat familiar with SGE (Sun Grid Engine, now Oracle Grid Engine) commands but am having a problem when running parallel jobs.
Present Machine configuration:
machine I - 12 cpus
machine II - 12 cpus
machine III - 12 cpus
.... so on ...
One_machine - 16 cpus
(I have all machine of 12 cpus and 1 machine having 16 cpus)
I want to schedule jobs on these machine such that if I ask for 12 cpus - my jobs should execute on any of the machines which has all 12 free cpus (eg machine I or machine II) in this case.
Eg. suppose I ask for 24 cpus
Option I : 12@machine1 12@machine2 ----- I need this
Options II : 10@machin1 10@machine2 4@machine3 ---- I don't need such a distribution
Hence, Option I is ideal here. Also, when running 12 jobs on machine1 (say) - even if all 12 cpus are not being used at some instance of time, none of the 12 cpus should be freed.
In short, until my run finishes, all blocked cpus should remain blocked.
If you may understand, the purpose here is to run some performance tests.
I'm using 'qrsh' to launch jobs.

I tried the following

It says on guides that it will ask me to reboot but it doesn't, so I manually did it and put the CPU Frequency Monitor on my taskbar. It does not have the options like it shows in the screenshots to set my CPU frequency..

View 4 Replies View RelatedUbuntu :: 10.4 - Overall Bad Sound Quality (Low Frequency)
Jun 28, 2010I'm a bit new in Ubuntu, but I am about to get a hang in it. I have previous use karmic koala and the version before that (cant remember the name for that) on my old computer and now I am using ubuntu 10.4 on my new computer. Ever since I installed Ubuntu for the first time, I noticed that the sound quality wasn't... the best. There isn't so much wrong with it, but like that this example. I played a FLAC file with some headphones (thru Ubuntu) and the sound quality sucked.. and then I played a mp3 file (with an ipod) and the sound quality was much much much better than the FLAC file.
I tired to play an HD movie over ....., where on Windows XP it sounds perfect, but with Ubuntu it kinda sux. The MP3 (Ipod / windows XP) is still better, than anything that is being played in Ubuntu. This is with almost every sound format I have tried. No matter if I play it with Rythmbox or vlc or some other player, the sound is wrong. I cant describe how it sounds.. but it is like it is going with a low frequency... or it is compress some how... Ever since I tried Ubuntu for the first time Ive noticed that something was wrong, but couldn't never really put my finger on it. I have dual-booted with windows XP and the sound in XP is really, really good compared to Ubuntu.

View 2 Replies View RelatedUbuntu :: Changing CPU Voltage & Frequency
Sep 26, 2010I am doing a project on how power consumption of a CPU can be improved by underclocking the lower P-states and overclocking the highest p-state.In this way you can increase both the performance of the chip and it's average power usage (assuming you don't run the chip at 100% 24/7).
To do this project I need to be able to change the voltage and frequency of the chip for all of the different p-states of the chip. On Windows I can use k10stat, RMClock or AMD Overdrive.
What can I use in Linux? I found k10ctl, but it always complained about not being able to find /dev/cpu/0, so I looked in /dev and noticed that their isn't even a cpu directory in there!
I have a moderate amount of experience so I don't mind changing kernels or doing other hard tasks to get this to work.
