Ubuntu :: 32 Bit And 2 X 1.66GHz Atom D510 CPUs
Jul 28, 2010
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?

Can you run Linux on this? [url] And will the WIFI work with Linux? I have been looking for something like this for a long time. I want to run Centos 5.5 on it.

Hi! What would be more preferable to install on my machine? I've read somewhere that if my CPU supports 64-bit, I should prefer that over 32-bit. What are the distinct advantages if I do?

I have a new PC with an Intel Atom D510 and would like to recompile the kernel with the options for the Atom CPU, but as you can imagine, compiling the kernel on the Atom is extremely slow. How do I compile the kernel on my faster X86_64 (AMD 965X) system for the Atom D510 system? I read some documentation on doing a cross compile and another on changing the architecture and subarctitecture.

I've got a new motherboard Intel Atom D510. There are two problems in Fedora 12 after installing (and in live, too)
1) there is no ethernet (no net, red "x" in net tray).
2) there is no PS|mouse. (only usb-mouse works!).

I'm trying to do a fresh CentOS 5.5 installation on a baby server with a Foxconn D51S based barebones system. BIOS is P04, the latest on their website.
When I have one 2GB memory installed, I am able to install the system and run it through some very vigorous testing without any issues. I have two DIMMs and both work just fine one at a time.
When I install two 2GB memory, it starts to crash hard during memory intensive operations, like mkfs or fsck.
I tested a 2.6.35 based kernel just in case it was an issue of old kernel + new hardware but the error persisted.
Google hasn't been helpful, and Foxconn support basically says "It runs windows, so that's good, right?").
What I've noticed is the system, when booted with one DIMM correctly reports that it has 2GB of ram (minus 8 megs for video, etc), but when I boot with both installed it seems to detect 4864MB of ram instead of the expected 4096.

I have a new Intel Atom D510 and I'm pretty pleased with it so far. The board is Zotac NM10-ITX.
My first issue was that during long and fast downloads (like transferring my home directory over the network) the system become pretty unusable: web pages would time out, windows would take more than few seconds to load, etc. I solved this by recompiling the kernel for the Atom. (The compile time wasn't that bad actually because the system is pretty simple and it was easy to isolate only the drivers I needed).
My next issue is that certain GUI-related things seem a little sluggish. For example, when the GDM loads it's not smooth like on other computers. When I log in, my background doesn't fade in gradually, it does so in about 1-2 frames. I was thinking this might be an issue with the GPU. It uses the i915 kernel module. Is there some tweaking I can do?
Code:
I was expecting to see a memory region of prefetchable memory around 128M here. Is this a problem?
What are you atom users doing to speed up your systems? I'm on Archlinux and I'm using a BFS patched kernel.

My 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)

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
model: 4

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.

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:
Quote:
Linux version 2.6.18-164.11.1.el5 (mockbuild@builder10.centos.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-46)) #1 SMP Wed Jan 20 07:32:21 EST 2010
Command line: ro root=/dev/VolGroup00/LogVol00
ACPI: Local APIC address 0xfee00000
[Code]....
Am I correctly understand that something wrong in BIOS? Or it is something else?

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.

When 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?

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?

I 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 get a wrong architecture error when I try to install the .deb .A fully 32 bit enabled install of Ubuntu 10.10 86-64 on a D525 Atom based system does not seem to work at all. It will not install with gdebi or the new Ubuntu software centre.I have the 32 bit required OpenMotif libs installed...and all the other stuff that is i386 arch works perfect. I really want to run the 64 bit os but perhaps I can dual boot it with Fedora 32. There is nothing in the asus bios of the board that says emulate i386 like with AMD 64 chips...I thought that the D525 atom was fine as it will run 32 bit XP or any 32 bit linux.
So what might be the trouble with running 32 bit software on Ubuntu 10.10 64 on this machine? Why does the Ubuntu hacked gdebi software install system insist that i386 software is the wrong arch for this intel atom?This is really maddening as my wife's work demands this citrix client, and the last thing that I want to do is run out and buy an oem of Windows 7.been there done that with 98, XP, and Vista I am looking to ditch her noisy POS vacuum cleaner vista machine..but I cannot do it until I have the linux citrix client installed and working.

I've a e-machine netbook with the atom n450 processor.
Even with a non-stressing use (only browser ad music player) the cpu gets too hot.
Today with lm-sensors i detected a 58°C temperature.
It's not a sensor problem because if i touch it i feel it really hot.
With Windows xp i haven't this problem.
The frequency scaling works (i don't know if well) because with conky i see it change.
What should i do or try?
On the system all the packages I've installed comes from the repository, all but volume icon.

I want to make a x86 based router using a mini-ITX board and I found 2 options, Asrock AMD-E350M1(~$140) and Intel Atom D525MW(~$94).
1. AMD-E350:
Pro:
It's slightly faster than atom D525.
It has AMD-V(virtualization support)
It can be used as HTPC(1080p)
It can be used for GPGPU
Uses ~max 25W for CPU+(capable)GPU
Con:
Single Channel Memory
PCI-e slot is bad for router( I found 4-port PCI NIC at $25. 2-port PCI-e cards are $60 and 4-port PCI-e cards are $150 )
2. Intel Atom D525:
Pro:
PCI slot(see above)
Dual Channel Memory
Cheaper than AMD E-350
Passive Cooling
Con:
Uses SODIMMs
It cannot be used as HTPC(doesn't play 1080p, not even 720p)
It cannot be used for GPGPU
I plan to use the mini-ITX board with 4GB RAM:
AMD E-350 with 4GB ram(1x$51)=$191 -> cpubenchmark.net score is 744. Regarding the CPU the value is 3.8952/$
Intel Atom D525 with 4GB(2x$29)=$152 -> cpubenchmark.net score is 714. Regarding the CPU the value is 4.6973/$
I would like to have a mini-ITX board that is capable of having one VM runing the router OS and 2nd VM runing pyrit on the GPU.
If it is possible to run pyrit on the APUs GPU I would choose AMD E-350 because I can put in PCI-e NIC to run the router OS. If not, I have to stick with Intel Atom D525, 4GB RAM would be a waste, but also I would waste a lot of CPU time.

When I shut down I sometimes get some weird errors on screen, and it stops shutting down until I hard reset (hold power down). The errors are something like
Code:
drm:atom op_jump atomBios stuck
drm:atom execute table locked atombios stuck
Also I have my pc set to schedule shutdown (gnome schedule, with "sudo shutdown -h now")My windows side has always shutdown fine, So I don't know if its an incombatilibty with my pc/mobo and the linux kernel ? (half the time it shuts down fine)(?might be due to spin down hard drive option?, or standby settings?)(hibernate on windows has never worked for me)

I've got a hankering to upgrade my home PBX from Trixbox on CentOS to SipXecs on Ubuntu 10.04 LTS.
The current Trixbox setup is running on a Gigabyte G33M-S2 with 2.2 GHz Intel Core 2 duo (There ain't no kill, like overkill). My needs are... ahem... modest, to say the least. The user base is currently five (5) people (all family members)... and would never grow beyond 10.
So, the Intel Atom D525 looks like I could cut down on power consumption. I'm thinking of going with the Gigabyte version found here [url]
If it works out well, I'm thinking of moving my email server (currently on Qmail, and showing its age) to a D525 board, and switching to Postfix.
Has anyone had any thoughts, experiences (good or bad), and/or "gotchas" with the Atom boards as a server (no gui).
