Guide to running multiple GPU work units

Mine was down when I got home, and got the same errors. Trying your fix now.

KieX's fix should work fine for you, it did for me. But as another said, it took a few times for it to work, didn't work the first. I tried again, and it started working correctly. :)
 
I gave up. Running one at a time while also using the other 3 cores of the cpu. Also some of those new betas are cpu betas as I am getting them on all rigs.

the new 7.05 gpu wu's may have more point value so you may get some output back from them?

Gave up? I didn't giving up was in a cruncher's vocabulary! :roll: I'm about to give up here with Win8 :banghead:
 
When I change the XML file, it doesn't like it. I get errors saying that the kernel and wcg_hcc file are missing. I remove the XML file and then it downloads both missing files. I then stop the client, restore the XML file and relaunch the client, then get this:

When I change the XML file, it doesn't like it. I get errors saying that the kernel and wcg_hcc file are missing. I remove the XML file and then it downloads both missing files. I then stop the client, restore the XML file and relaunch the client, then get this:

Strange error, don't think i had the same one. I ended up reinstalling. I let it connect, halted work, shut down, replaced xml file, and then restarted. Worked the second time I think.
 
I was getting all kinds of dumb ass errors too. I finally said the hell with it as my head hurts to much right now to even remotely try and get it to work right. I may just leave mine with the 1 gpu work unit that way if they do more changes I don't have to worry about them.

That may be what I have to do too, unfortunately
 
The wierd thing is my other rig with the 6850's in it is still banging along and is still getting 6.56 wu's along side of the 7.05 units.
 
I finally got it running. Man, what a pain in the ass :mad:
 
The wierd thing is my other rig with the 6850's in it is still banging along and is still getting 6.56 wu's along side of the 7.05 units.

That's the problem with this hack-job experimental stuff. Very temperamental :(

I'll say, my temper is getting shorter and hotter :laugh:
Seriously, about to install Win7 again on my old hdd, be back soon
add: installed, everything running well, as far as I can tell. Let's hope it continues

Got it working without too much fuss :)

Hmm, after a hiccup I got my multiple WU's working but it's no longer sending gpu only tasks.

I'll uninstall all the client software and re-install BOINC from web. Start from scritchy scratch. See what happens.

EDIT Awesome - back to work. :)

Updated the OP with the current version numbers. Sorry couldn't do that yesterday. Added info on the CPU setting to keep it all in same place for any new starters.

WCG has recognised the impact of changes in ver.number to us app_info file users so they will be posting that information whenever a new version is released. This is a new phenomena for them, so let's not forget.. though it's a PITA for us, it's because we're in new terrirtory. My new year's wish will be that in future all of this will be simplified.

Whenever a new version is released, the new files need to be downloaded before any modified app_info will work properly. So that requires to detach from project to delete all the Data folder, attach again in default install mode to get the new run-files, then insert the modified app_info file once all taks are completed.

You guys are pro's at this by now, but thought I'd try describe that process for anyone else new to this thread.

the new 7.05 gpu wu's may have more point value so you may get some output back from them?

They are two jobs wrapped up in one WU. So you get more or less the same amount of points as before, though each WU is longer. It was done so that the fewer WU would be easier to handle by the servers :toast: We must have been really punishing those validating servers.
 
You are probably correct on the old wu punishing the servers.... when the wu was switching over last night I had a bear of a time getting my work to report on a regular basis :rolleyes:

and the point value/processing time on my rig is about the same on this wu as it was on the older one.

Thank you for your efforts! :toast:

I don't know how you've been able to stand the aggravation with all of the work you have been doing on helping to get this process running smoothly.... my PC would have been smashed to bits and smoldering in my driveway by now if I was trying to do this. :laugh:
 
I take my stress out on ppl in tribes accend as i can still play that game while boinc is running full speed.
 
Good info KieX, thanks again. As Norton said, we appreciate your hard work and undying patience. I know that I'm no pro yet! I've had to redo all this so many times since beginning, and it is never easy and it never works out the same for whatever reason, can be very fickle

It sure does feel good to think we were punishing those servers wirh all our returned work lol, we must be doing more than was anticipated :toast:
 
Thanks for updating this KieX, I'm going to try it on my HD7770 tomorrow afternoon :)

What have you been able to do with the 7770 so far?

When I tried Tuesday I wasn't able to get things working properly. I meant to try yesterday, but I didn't have time. I'm home for the weekend, but I'm going to see what I can do when I go back to school tomorrow. Ideally, I'll run 3 WUs on the GPU and then HCC or something on the CPU :toast:
 
Quick question guys. If I want to run 2 GPUs in a system, say a 7950 and a 7770, or a GTX 470 and GTX 465, and I am not using the app_info.txt, does BOINC automatically pick up both GPUs and assign 1 WU and 1 CPU core to each GPU?

I can only answer with using 2 of the same cards. It's just like you said, as long as you have it set to use gpu in the settings. :rockout:

Yes sir- that's what should be happening (app_info not needed). If it's a crossfire/SLI set you may have to disable that as I believe that doesn't play well with the wu's.

If you have any problems getting BOINC to recognise more than one card, go to the data folder (Usually: C:\Program Data\BOINC\) and edit the cc_config.xml file to include the following line:

<use_all_gpus>1</use_all_gpus>

Not needed normally, but just in case you do have problems, this is what you need to know.

This was actually needed on both my GTX460 and GTX470 systems to run both GPUs--so as always, YMMV
