Hey all,

I recently switched to MW@Home as well, the project goals interest me more than most of the other projects out there.

And since I'm seeing that I should be able to use my 3870 to do some crunching I was looking forward to that.

However it's not working quite right... Well at all.

I have BOINC 6.10.18 (Newest I think) & Catalyst 9.11. BOINC says: 12/22/2009 8:24:31 PM ATI GPU 0: ATI Radeon HD 3800 (RV670) (CAL version 1.4.467, 512MB, 544 GFLOPS peak).

And the MW@Home web site doesn't show my card in the GPU section about my computer.


Any thoughts on what I need to do? MW isn't even downloading the GPU client and completes GPU scheduler requests saying "got 0 new tasks".

Would putting the optimized GPU client into the directory perhaps kick start it?

And if that might work, is there a way to run the optimized CPU and GPU clients? Going to guess it requires at least the "merging" of the two .xml files?

Thanks for any suggestions!

They have not upgraded the server software to enable direct downloads of the ATI app. You will need to install the optimized app.

Well that would do it...

Am I correct in thinking that I just need to add the body of the .xml files together?

---

Sorry to post two in a row, but I'm not seeing an edit button on my last post?

So I tried to merge the two .xml files in between the <app_info> </app_info> tags and I'm getting an error about having duplicate apps. Didn't give it enough time to see if it would download and start crunching any gpu wu's though. Figured something bad was going to happen and pulled the plug on it. But this could be completely normal.

Tried replacing the cpu app with the gpu app and the wu's didn't do a thing. Which is certainly better than them erroring out and all.

So I'm suspending new wu's and letting the ones I have finish up overnight and then just putting the optimized gpu app in tomorrow morning. And hope that the standard cpu app will run at the same time.


But I'll keep checking this and hopefully someone who knows how to get both to run will read this and tell me where I went wrong.

Thanks!

Its one of the 'benefits' of the boinc board s/w.
iirc, unlikely, you are only allowed to edit *your* posts for an hour after posting them.

Try reading some of the opti-app threads, eg this one.

Pay special attention to the 'read the readme' parts.
And also check that your card does double precision according to this chart.

If you are trying to process both CPU and ATI GPU tasks on the same computer it will not work at this project. The tasks downloaded are the same and once you are using an app_info.xml file you can only use one application or the other, either CPU or GPU but not both.

If you try to use an app_info.xml with both ATI GPU and CPU applications in this project all tasks downloaded will be branded with the highest application version 20 (ATI GPU) and no tasks downloaded will be branded as version 19 (CPU). You can do it temporarily for a batch but it involves a bit of mucking about and is not practical or worthwhile, especially on computers that have 1 or 2 cores.

In some projects if the version numbers are different it is possible to process both CPU and GPU tasks when the applications are automatically downloaded and you do not use an app_info.xml file.

Thanks Tombei, that's exactly what I was looking for.

I was starting to think that something like that was the case when I wasn't able to get it to work.

Guess that just frees up my cpu to run another project or something.


Verstapp - I actually read most of a few threads on the opapps and nowhere did anyone mention that you could only run the gpu or cpu. Which surprises me, I would have figured someone would have brought it up at some point.

It has been a while since I saw it mentioned. Could be back when the apps came out.

Doesn't expecting the unexpected make the unexpected the expected?
If it makes sense, DON'T do it.
