xorg.conf file problem

I have a Red Hat Enterprise 5.3 I have a Tyan S7025 Motherboard, with two Quad-Core Xeon E5520 (2.26 GHz), 24GB DDR 1333MHz ECC Registered w/Parity and 4 Tesla C1060s. I am having trouble getting the operating system to recognize the Teslas. I have the latest drivers installed and the most recent version of cuda installed, but when I run the nvidia-xconfig but after that when i reboot the machine it doesn’t recognize the Teslas. I open the xorg.conf file open and this is what i see (pasted below). The problem is in the device section for the four Tesla cards is in the driver section it says “nv” which I’ve read is supposed to say Nvidia, but when I try i get a blank screen and I have to restore to the original config file. Then under BoardName it says “Unkown Board”.

If anyone has a similar setup with the Tyan Mobo and at least 1 Tesla. If you could post your xorg.conf so i can get a reference point it would be greatly appreciated.

Use the script in the release notes to load the driver and create the /dev/nv* entries.

Where can I find the release notes?

[url=“http://developer.download.nvidia.com/compute/cuda/2_3/sdk/docs/cudasdk_release_notes_linux.txt”]http://developer.download.nvidia.com/compu...notes_linux.txt[/url]

I read the release notes but unfortunately I am very new to linux and I’m having a hard time understanding what to do to make these teslas register so i can access the via cuda.

Honestly, I can’t find anything about /dev/nv* in the release notes either. This page might be more helpful:

http://acceleratedcomputing.blogspot.com/2…060-on-mac.html

It says ‘Mac’ but is really about linux (on a Mac)

EDIT: Did you (manually) install the Nvidia drivers? Because the installation will at the end ask you if you want it to rewrite the xorg.conf to use the new driver, which I’m ready to bet on is what most people want. That should you rid of the ‘nv’ entries supplied by the distribution.

I have a SuperMicro SuperServer with (1) Quad-Core Xeon E5520 (2.26 GHz), 12GB DDR 1333MHz, (1) Quadro FX 370LP and (2) Tesla C1060s.

To get mine working, I had to use the “Xorg -configure” command, then manually edit the entries. I had to disable the onboard display and run my additional Quadro FX card to render my display in three dimensions. You should see the “#” where I disabled my onboard Matrox display.

Here is my xorg.conf file:

I see several problems with your xorg.conf file. There are 5 screens listed in “ServerLayout”. Since you are running Teslas, they should all be run without trying to port the graphics to a display. Delete all these entries besides “Screen0”.

#1- Have you tried using the nvidia-xconfig command?

#2 - If #2 doesn’t work, you may have to manually configure your xorg.conf file according to the data from the “lspci” command. Simply copy the data from the lspci readout to your xorg.conf file.

I have a SuperMicro SuperServer with (1) Quad-Core Xeon E5520 (2.26 GHz), 12GB DDR 1333MHz, (1) Quadro FX 370LP and (2) Tesla C1060s.

To get mine working, I had to use the “Xorg -configure” command, then manually edit the entries. I had to circumvent using the onboard display and run my additional Quadro FX card to render my display in three dimensions. You can see this in the “Screen0” section - I use “device1” instead of the normal “device0”.

I see several problems with your xorg.conf file. There are 5 screens listed in “ServerLayout”. Since you are running Teslas, they should all be run without trying to port the graphics to a display. Delete all these entries besides “Screen0”.

Your “nv” entry should read “nvidia” - you can change that manually.

Last - a couple of ending comments/questions:

#1- Have you tried using the nvidia-xconfig command?

#2 - If #1 doesn’t work, you may have to manually configure your xorg.conf file according to the data from the “lspci” command. Simply copy the data from the lspci readout to your xorg.conf file.

Lastly… a comment on your setup.

As I write this today, there is no motherboard which can fully use 4 Tesla C1060 cards. The PCI-E pipeline traffic maxes out with 2 Tesla cards. Hence, there is no reason to have more than 2 Tesla cards in a 1U unit - you can’t use them… It would be wiser to put those in a 2 slot, 1U unit, connect the two 1U units with a 20GB Infiniband connection - then cluster them with Rocks or MOSIX.

I talked with Nvidia before building my configuration - they said that there are systems which use 4 cards (specifically the S1070 setups), but these are simply C1060s which are rate-locked at 1/2 speed - effectively 2 C1060s at full speed.

Whoever sold you that system was hankering for a commission. =D

  1. For your Tesla card to be recognized on a RHEL 5.x system, you have to install the Nvidia drivers and also use a startup script for the /dev/nv* to appear.

  2. http://acceleratedcomputing.blogspot.com/2…060-on-mac.html This link actually describes the procedure for a Tesla C1060 installation on a Mac Pro running CentOS.

  3. Also make sure the drivers you have are for the same kernel you have on your system, else update your kernel to match the driver specified kernel.
