<!-- Exclude World Community Grid's Help Conquer Cancer GPU app on main display - makes graphics slow, even on 660 TI -->

I also added a space after the web address <!-- Exclude World Community Grid's Help Conquer Cancer GPU app on main display - makes graphics slow, even on 660 TI --> <exclude_gpu> <url>http://www.worldcommunitygrid.org </url> <device_num>0</device_num> <-- app>hcc1</app --> </exclude_gpu> Failing this try the simple version: <exclude_gpu> <device_num>0</device_num> </exclude_gpu> Then add the web address for the next test <exclude_gpu> <url>http://www.worldcommunitygrid.org </url> <device_num>0</device_num> </exclude_gpu> Finally add the app as above.

P.S. A General "no WCG on device 0"... more things to try, just enter the url and device number, no <app>. Since there's only one WCG GPU application for longer, I'd not worry about how to spec it in general for WCG. SekeRob, thanks for the detailed advise. What did I do wrong? I commented out the app line per your instructions just like the first line comment. I even rebooted. No joy. (device 0) is still running. <!-- Exclude World Community Grid's Help Conquer Cancer GPU app on main display - makes graphics slow, even on 660 TI --> <exclude_gpu> <url>http://www.worldcommunitygrid.org</url> <device_num>0</device_num> <!-- app>hcc1</app --> </exclude_gpu> Both of my GPUs are of the same make/model and only Cancer Research at WCG used GPUs for crunching at this time. Help is still needed.  The line causing the error is bolded in the quote. XML comments cannot be within a section, so the comment (<!-- app>hcc1</app -->) in <exclude_gpu> is causing an error. Just remove the entire comments line and it will work just fine, I've used it a number of times.

Thanks OldChap for the response. However, if the <exclude_gpu> tag is not being recognized would not the lines inside the tag also be unrecognized?
----------------------------------------FYI - I tried removing the lines inside the exclude_gpu tag except for the <device_num>0</device_num> line, as you suggested. No joy. Both of my GPUs are still chugging away.   O/S -LinuxMint 64-bit, Release 13 (maya). DE: Cinnamon |

I believe you may have missed my post just above your response to OldChap. It's the comments line in the <exclude_gpu> that caused the error.
----------------------------------------I have found that using only the <device_number>0</device_num> in the <exclude_gpu> doesn't work for me. Either use what SekeRob suggested of what I have in a couple of PC's: <cc_config> <log_flags> ... </log_flags> <options> ... <exclude_gpu> <url>http://www.worldcommunitygrid.org/</url> </exclude_gpu> ... </options> </cc_config>

wplachy - won't this block both GPUs?
----------------------------------------<exclude_gpu> <url>http://www.worldcommunitygrid.org/</url> </exclude_gpu> What about... <exclude_gpu> <url>http://www.worldcommunitygrid.org/</url> <device_num>0</device_num> </exclude_gpu> I want one crunching and the other Boinc free.

OldChap, the space introduced in the <url> borgs the line. It's just how the forums convert a http address to become a link to include the <url>, but the text format of cc_config.xml wont do that and interpret the line properly.
Et Alia, a device number has to be included, else the config wont know what device the exclude pertains to. Oh, and <use_all_gpus>0</use_all_gpus> also does not work if the devices are of same spec. Then also BOINC will use both. To me, a blunt <exclud_gpu> followed by <device_num>0</device_num> as was earlier proposed by OldChap, would constitute a general device exclude (we're in trial/error mode). Including <url> and <app_name> (Inconsistent to the <name> tag used in app_config and app_info and client_state.xml, to me, but to Berkeley devs it surely will be per some undecipherable spock logic), further refines which project and even which science has to run on card 0, 1, 2, 3 etc. |

You are correct, the alternative I posted will block all GPU work for WCG. The second, which is what SekeRob posted, will block work for WCG on the device_num specified. The only problem with the one in the post I first replied to was the comment line (<!--) in the <exclude_gpu> section. If you remove just that line it should work as you wish.

Thanks to both Bill and Rob for your insight.
----------------------------------------I hope you see that what I am trying to do (somewhat blindly having not had the problem) is introduce the idea of testing this line by line. Maybe I should refrain from guessing. Sorry Gandalf if I confused you. |

Maybe I should refrain from guessing. Sorry Gandalf if I confused you. Don't worry OldChap. I was born confused. You're a little late for that.  Where does that leave up? What does an <exclude_GPU> group need to look like? Right now I'm turning off both GPUs just so I can get some of my work done. Not a good workaround. O/S -LinuxMint 64-bit, Release 13 (maya).

I feel you should go with the one that you posted which did not work but with the correction that wplachy posted. which would leave you with this:
----------------------------------------<exclude_gpu> <url>http://www.worldcommunitygrid.org</url> <device_num>0</device_num> </exclude_gpu> You may have to change the device number depending on which card you wish turned off. From sekerob's comment I think he says that any further lines added to this are used to refine which science is excluded but for now as there is only one type of GPU work on WCG you should be good [Edit 1 times, last edit by OldChap at Jan 22, 2013 7:04:54 PM] |
