I have an i7 980x (hexacore) machine, installed with ubuntu 10.04. Has the stock 2.6.28-15-server #52-Ubuntu SMP kernel. When I check my /proc/cpuinfo, I can see only 8 CPUs. Was expecting to see 12. Is there any way to get all my 12 CPUs.
View 1 RepliesI am using NFS to mount large LUNs from my SAN.have one lun already setup and configured. I am adding an additional partition from the same SAN but I am confused on the setup. I know the LUN is connecting to my NFS serve correctly because I see it listed in my/proc/scsi/scsi as an additional LUN. What I don't see is the drive being displayed in fdisk -l.I did notice one thing though, when I disable the host mapping from the SAN, I see it removed from the /proc/scsi/scsi file AND my fdisk information changes from /dev/sdb TO /dev/sdc (see changes below)
fdisk -l without host mapping to SAN:

I installed 64-bit 10.4 LTS side by side with CentOS, and after install done, grub only showing ubuntu.
I ran 'os-prober' and it detects my CentOS install. I ran 'update-grub' and it updates grub, but doesn't add CentOS. I thought that should do it. What did I miss?
I'm looking for a CPU frequency applet which monitors the frequency of ALL CPUs at once.
Does it exist such applet?
For some reason SAMBA is not showing up

read only = no

force user = nobody
guest only = yes

I can see Ubuntu on the LAN, but nothing being seen under it. What is wrong with it? /var/www has been chmod already, and set to 777
My server name, salamander, is not showing up in windows networking or in the networking items on linux computers. I have checked, double checked and tried several samba settings to see if I can make it work, but to no avail. Its shares can be accessed by any computer by going directly to 10.10.1.101, salamander's fixed IP.
My workstation, bear, shows up. I edited hosts to read: "10.10.1.101 salamander"
Any machine can access the share on salamander using the ip address, but not even Bear can connect directly with the computer name.
When I go to networks in Salamander, all it views is itself and a windows network. Inside the windows network is only salamander.
Bear shows up in the list of servers, and also has samba running. Eagle and Bearcub are also ubuntu without samba and do not show up in the list either. Understandably so.
Here is my smb.conf:

View 7 Replies View RelatedMy 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)
1.What is a time slice?
2.Do CPUs cut procceses in half? When is a process stopped for another to take place?
I'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
vendor_id: AuthenticAMD
cpu family: 16

I'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?
I'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!

I 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?
Not 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:

Am I correctly understand that something wrong in BIOS? Or it is something else?
As the title says the machine name is not showing up in the attached devices list on my router. Is there a file where I need to add the name? Or is this an issue with the router? The router finds all the other machine names on the network except my 3 servers.

I 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.

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?
While searching for the maximum numbers of CPUs supported by CentOS 5 x86_64 I found the following page: [URL]. 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 RelatedI 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.
