[RESOLVED]] Linux. Multiple GPUs.
Hi!
Debian testing, svn boinc version at revision 26158, catalyst 13.1.

1 wu is works fine by defaults.
I've read this, and it's worked. A little.
All previous tasks were crunched in 4-way, but no new wu were downloaded.

Looks terrible

Re: 7770 and debian. errors
Hi,

If you post the content of your cc_config.xml and app_info.xml [If you're using that], an experienced GPU cruncher that has 2 or more set to crunch concurrent on a GPGPU will be able to help you. Also tell us the exact BOINC version.

Not sure, but you're trying downloading a 32 bit version app, so your Debian must be fitted with the appropriate libraries to process these. The HCC-GPU app may exist though for Linux in 64 bit.

Re: 7770 and debian. errors
I don't have cc_config.xml.

app_info.xml
<app_info>
<app>
<name>hcc1</name>
<user_friendly_name>Help Conquer Cancer</user_friendly_name>
</app>
<file_info>
<name>wcg_hcc1_img_7.08_x86_64-pc-linux-gnu__ati_hcc1</name>

</app_info>


Exact boinc version is 7.1.0. Lies here. Compiled from source.

>Not sure, but you're trying downloading a 32 bit version app
Could be, but why? There is a 64-bit version for linux.

I'm using a 64-bit linux.

Maybe something wrong with teg
<platform>x86_64-pc-linux-gnu</platform>,
cause guy on ubuntu said, that all is fine for his system?
And, when boinc crunching 1 WU on my system, it uses 64-bit version. I've checked.

Buy the way, i've tried make the file app_config.xml , but it has no effect. I suppose, it's windows only.

Re: 7770 and debian. errors
Wherever the branch or trunk 7.1.0 version comes from, not production endorsed. We're now on 7.0.45 as latest alpha build from Berkeley, where WCG [unofficially] supports 7.0.31-7.0.45, builds from latter having the app_config.xml feature.

Suggest to revert to a supported build and ditch app_info [it will be banned soon anyhow], and use the much simplified app_config.xml which does not require any platform speccing. The server will know what to send based on client info... and No, app_config.xml applies to all platforms for 7.0.40 and up [officially].

Re: 7770 and debian. errors
SekeRob, thanks.

I've build a new version from git. It works for now. Still 7.1.0 though. )
boinc --version
7.1.0 x86_64-pc-linux-gnu


And I've found a tutorial for multiple GPU's.

My app_config.xml :
<app_config>
   <app>
      <name>hcc1</name>
      <max_concurrent>4</max_concurrent>
      <gpu_versions>
          <gpu_usage>0.25</gpu_usage>
          <cpu_usage>.25</cpu_usage>
      </gpu_versions>
   </app>
</app_config>


7770 is crunching 4 WU's ( 0.25 CPU + 0.25 ATI GPUs ) for about 10 minutes each.

The problem is solved. I suppose.

Re: 7770 and debian. errors [RESOLVED]
Coowl. Why your private build pumps out 7.1.0 (which would in development be the pre-alpha to the 7.2.xx series), I do not know... maybe it's because it's a way to signify private builds?

On app_config, don't know what hardware you got running but having 4 HCC-GPU tasks supported by just one CPU thread [<cpu_usage>.25</cpu_usage>] is dapper. If it runs it runs, but experimenting with a 0.5 value [2 GPU tasks supported by 1 CPU thread] might run things a faster. "Experimenting" would be the operative word.

If you edit the OP post title and insert [RESOLVED], we know there's a fix.

P.S. Ubuntu forum supporting Debian?... not expected them to do that. These are the Debian forums which you may already know: http://forums.debian.net/

I'll try different options. Sorry, but my english is to weak to explain my points. I understand you, of course. With online translator. ))

Actually, Ubuntu is based on Debian, so in most cases, all that works in Debian will work in Ubuntu.

Re: 7770 and debian. errors [RESOLVED]
Hello Siu,
I got a Radeon 7750 and have not figured out how to get the opencl driver.

Can you, please help?

I have tried debian squeeze, ubuntu 12.10, and Lubuntu.
I am currently trying Lubuntu.
lspci sees ... Advanced Micro Devices [AMD] nee ATI Cape Verde PRO [Radeon HD 7700 series]

a lsmod shows a module named "radeon".
a modinfo shows the filename:
/lib/modules/3.5.0-25-generic/kernel/drivers/gpu/drm/radeon/radeon.ko
and firmware
radeon/VERDE_rlc.bin
radeon/VERDE_mc.bin
radeon/VERDE_ce.bin
radeon/VERDE_me.bin
radeon/VERDE_pfp.bin

and boinc-client 7.0.27+dfsg-5ubuntu0.12.04.1
when starting, boinc says: No usable GPUs found.

I assume I do not have the opencl driver.

How can I get this? (preferably on Debian)??

T H A N K Y O U!!
Jay
