Experience with Ubuntu 10.4 + Radeon 6990?

[jharbert]

Hey guys,

I'm setting up a box with Ubuntu 10.4 (previously was running 11.04 but ran into too many issues) along with a Radeon 6990.  I'm having some issues presumably getting OpenCL to see the GPUs.

I have Catalyst 11.4 installed and SDK 2.4 installed at /opt/AMD-APP-SDK-v2.4-lnx32/

fglrxinfo gives the following:

Code:

display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: AMD Radeon HD 6990
OpenGL version string: 4.1.10666 Compatibility Profile Context

display: :0.0  screen: 1
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: AMD Radeon HD 6990
OpenGL version string: 4.1.10666 Compatibility Profile Context

SDK 2.4 doesn't seem to have CLInfo in bin/, but 2.1 and 2.3 did, and it did not show any GPUs, just the CPU.

The output of the bitcoinpool poclb-mod.py script shows this issue as well:

Code:

$ python poclbm-mod.py

# Use the --help flag for more options.

Any idea on what is going on?  I'm assuming it is an issue with OpenCL or the 2.4 SDK detecting the card, but I'm out of ideas..

My xorg.conf:

Code:

CLInfo moved into a different directory in SDK 2.4 but if you search around you'll find it. I recommend Catalyst 11.3 and SDK 2.3 (I also have a 6990 running Ubuntu 10.10).

I have Catalyst 11.4 installed and SDK 2.4 installed at /opt/AMD-APP-SDK-v2.4-lnx32/

find /opt/AMD-APP-SDK-v2.4-lnx32/ -name CLInfo  ... should tell you where it is

The output of the bitcoinpool poclb-mod.py script shows this issue as well:

Did you do export DISPLAY=:0.0 before running poclbm-mod?

[jharbert]

Thanks, Ghost.

I ended up putting 11.3 and SDK 2.3 on a fresh install, copying some of the files over directly instead of doing a make, and removing the 64-bit files.  OpenCL then detected the GPUs.

I messaged this but thought I'd include in the thread in case anyone else wants to chime in:

Thanks for the help with the Catalyst and SDK versions.  I'm curious how many mhps you're pulling per core on the 6990 using 11.3 and 2.3.

I'm getting way lower than expected, ~250mhps per core.  Running 1 core alone it's about 450 or so.

Did you have this issue too?  I'm thinking about putting on windows 7 just to see if the driver differences increase the hash rate.

Cheers

That's interesting...I was having all sorts of trouble with 10.10 (cloned from a 5970 based rig...but with sdk 2.4 and catalyst 11.4) and a 6990 (it wouldn't even read the clocks or temps using aticonfig)...I upgraded Ubuntu to 11.04 and suddenly everything started working.

Have you tried phoenix?

[jharbert]

Steve / Ghost,

I'm tempted to go back and try it again with Ubuntu 11.04 and the newest Catalyst drivers and SDK - since I handled the deployment of the SDK files differently this time around.

But, I think I'll throw win 7 on it tomorrow and see if I notice a big difference in mhps.  I'm not feeling very confident in the Catalyst 11.3 drivers running on my installation.

I'm also wondering whats with 48% GPU load while running two instances of the phoenix miner, 1 per core:
 

Code:

$ aticonfig --adapter=0 --od-getclocks

Adapter 0 - AMD Radeon HD 6990
                            Core (MHz)    Memory (MHz)
           Current Clocks :    950           1250
             Current Peak :    950           1250
  Configurable Peak Range : [500-1200]     [1250-1500]
                 GPU load :    48%

$ aticonfig --adapter=1 --od-getclocks

Adapter 1 - AMD Radeon HD 6990
                            Core (MHz)    Memory (MHz)
           Current Clocks :    950           1250
             Current Peak :    950           1250
  Configurable Peak Range : [500-1200]     [1250-1500]
                 GPU load :    48%

Hello,
do you have any results yet? Are the 6990 running better on Win7 than Ubuntu? What did you end up using?
And which hashrate do you achieve with your current configuration?

greetings

[jharbert]

We found support in win7 to be much better, making performance much better.  I can get about ~400mhps per core, so about 800mhps per 6990 without many problems (cards overclocked to 910mhz)
