1) Message boards : Number crunching : Somethings must be faulty -> AMD gpu usage at nearby 1-2 % ? Clueless.. (Message 1167)

3h30m 68.6 % , and it's getting slower. *chewbacca sound*. dam...
I'll suspend them from crunching, and start over with some new ones...

ok, on the next two wus I'm running with
more cpu usage, means:

cpus = 0.80
gpus = 0.50


Running very wrong 5% in 30 minutes. No way !

Comeon, there must be a way faster ! Anybody out there ? I can't effort this to pay really !

! BIG HELP !


Change the cpu numbers back to 1.0 so it uses a whole cpu core and then run multiple gpu workunits at the same time, I'm running 6 on my 1060 and it;s barely reaching 10% but is banging them out in a little over 5.5 hours each. You use an app_config.xml file like this:

<app_config>
<app>
<name>amicable_10_20</name>
<max_concurrent>4</max_concurrent>
<report_results_immediately/>
<fraction_done_exact/>
<gpu_versions>
<gpu_usage>0.25</gpu_usage>
<cpu_usage>1</cpu_usage>
</gpu_versions>
</app>
</app_config>

Save the file as a txt type file, use Notepad in Windows, and save it to c:\programdata\boinc\projects\ the one with ammicable in the name. Change the <max_concurrent> line and the <gpu_usage line to run more wu's at one time. For instance to run 6 at one time you change the 4 to a 6 and change the 0.25 to 0.16, to run 8 at one time you change the 4 to an 8 and the percentage to 0.125, then open the Boinc Manager and click options, read config files. BE CAREFUL though as that will cause your existing wu's to restart from the beginning but you will be running 4 at one time or 6 or whatever. Experiment with how many you can run at one time before the time starts going up, then back off one wu.

I have two GPU's in my PC, both nVidia. One a GTX1080 the other a Quadro K2000.
How can I set up to run two or more tasks on the GTX1080 but just one on the K2000?
Right now the K2000 is at 90%, but the GTX1080 is at 8-12%, based on GPU-Z.


You can install Boinc again in a different directory and then exclude one gpu from each of them , then you can tweak the settings individually.

It's because Boinc is written as a 32bit program and that's the limit it can show, it USES all of the memory until some Project comes up with a greater than 4gb workunit itself, which SO FAR none have done yet. A 64bit version has been discussed but I don't know how far along it is.



Is that really the case? BOINC has been offering 64bit versions for years although a 32bit download is still available. Additionally many projects offer 32bit and 64bit applications although Amicable Numbers only offers 64bit applications. You can peruse the download offerings and see both x86 and x86_64 offerings: https://boinc.berkeley.edu/download_all.php OR https://boinc.berkeley.edu/dl/


You are talking different parts of Boinc, there is a Server side the Projects run and Client side we crunchers run.

Per your direction I did the right click, edit option. When the file opened using Word, EditPad, and NotePad, each had several pages of text. Clearly that wasn't right.

Copied the config file again as listed on this page, did both the "right click/edit" and "open with" option using NotePad. Pasted the config file contents and saved.

Did the right click/edit again, and it looked good this time. Also did the "open with" NotePad option and it had just the config as listed below, so no excess stuff this time

Still getting an Missing <app_config> in app_config.xml error message...

Below is what was copied, directly from the file by right clicking on it, :

<app_config>
<app>
<name>amicable_10_20</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>1</cpu_usage>
</gpu_versions>
</app>
</app_config>


Is the error message the same if it can't find or doesn't see the file as it would be if it was a faulty script? I'd like to verify Boinc can read/run "any" app_config file at this point. I run Amicable, GPUGrid, Rosetta, WCG, CG, NF, and Seti.

Is there a config setting in the Boinc manager where it sets where to look for any app_config files?


Did you save the file as a txt type file but with the .xml extension? If so and it's in the Boinc/projects/ammicablenumbersproject folder then all you need to do is go into the boinc Manager and click on Options, Read config files and it will run it, any errors will show up in the Event Log under the Tools tab.

The GTX 1080 ti and RTX 2080 ti both have 11GB RAM, but only 4GB shows up in BOINC data ;)

There is no way to tell BOINC to use different app_configs for different cards on the same host, right? For instance, one of my machines has an RTX 2070 and two GTX 1060 3GB and I'm getting screenlag with two tasks at the same time (screen connected to one of the GTXs), so it would be ideal to have the RTX crunch two and the rest only one.

Is it really necessary to assign a full CPU core to each task even with the decrease in usage more tasks entail?


There IS if you load up two different copies of Boinc itself into different locations on your harddrive. Then you just need to exclude one of the gpu's from each copy of Boinc and set the settings you want for that gpu.

to start banning pc's with just 2 errors out of 242 workunits seems a bit harsh. What's the procedure for the guy to bring his pc back? In the banning process he had more workunits on his pc that he finished crunching but was NOT allowed to return them to even figure out it the problem was fixed or not, he had to abort them all and move to another project, where the graphics card is working just fine.


It's not harsh, because extremely few computers actually get banned here. He needs to check his GPU, run stress tests and make sure it doesn't crash or give errors, doesn't overheat, and I'll unban it then. "Working just fine" depends on the type of workload. It may be just on the edge for some projects and run fine, but cross the edge and fail sometimes on other projects.


He's not a rookie cruncher and has been crunching for a long time so understands all that, but it's okay 'lots of fish in the sea' as they say and he's now happily crunching just fine at another project.

1 error detected in the compilation of "C:\Users\steve\AppData\Local\Temp\OCL2252T1.cl".
Frontend phase failed compilation.

OpenCL.cpp, line 397: Trying to disable 'goto' and build again
01:16:06 (2252): called boinc_finish(0)

please tell me how this is a USER CAUSED ERROR? Because I too could be banned if this is a problem caused by the users!!

That PC has this message in all tasks' logs, including a few hundred valid ones. It's normal: in this case it failed to compile because of a known issue with amd drivers and a workaround was applied, so it compiled and ran fine after that.

But incorrect result was returned for a few tasks out of a few hundred valid tasks. This is a direct indication of unstable hardware. Many similar configurations run with the same message in logs, but without problems (validation failures) on this project.

Only validation failures are counted - it's when a client didn't report any errors on exit, but returned incorrect result. This can jeopardize the whole project's target and can't be tolerated.

Only "Completed, marked as invalid" status is counted for banning.

Because I too could be banned if this is a problem caused by the users!!


No, your computers have 0 "Completed, marked as invalid" tasks.

P.S. There are over 5000 hosts that run Amicable Numbers every day. Only 3 hosts are currently banned, so please don't exaggerate this problem.


I'm not trying too...the point is the host did Valid (240) workunits and ONLY· Invalid (2) ones and yet it was banned. My point is that perhaps your criteria for banning is a bit too sensitive and then to say 'well it's automatic' isn't being genuine because SOMEONE had to set the criteria for the 'automatic' procedure to be implemented. It's not built into the Boinc software to do that or several other projects would have long ago banned hundreds of graphics cards, but they haven't. This is like the accounting department telling me 'the computer made a mistake', NO computers don't do that, they only do what they are told to do that's why we all love them, they can do the same thing over and over and over again until either a part fails or the programming fails, but they do not randomly ban pc's or make mistakes.

I don't want to get into an argument here, it's your project and you can run it the way you like, but to start banning pc's with just 2 errors out of 242 workunits seems a bit harsh. What's the procedure for the guy to bring his pc back? In the banning process he had more workunits on his pc that he finished crunching but was NOT allowed to return them to even figure out it the problem was fixed or not, he had to abort them all and move to another project, where the graphics card is working just fine.

I did 1300 good work units and 4 invalid and you banned my computer!!!!!!! BYE!!!


Do you realise this ban was automatic? Unless you fix this PC, it will stay banned.


You guys do realize that he's using the latest driver and the problems was:

And only 2 hosts have been banned so far, and both wasn't mistakes. No false positives so far.

Both of them are mine, both are arm64 systems running an older client. I need to recompile the new source.

I only see one "invalid" on one of them and two on the other but the history is pretty short.


I have a "banned" host too, I think it's because the gpu is too old to crunch here and even though it tried I have 4 bad units so I aborted the rest of them,13 of them, and moved it to PrimeGrid, where it works just fine. It's an AMD 6670 so not new by any stretch, I don't care if it can't crunch here, it's way too slow anyway.

There is a problem, see:

Whitelist issue: Amicable Numbers not showing in the NN
https://github.com/gridcoin/Gridcoin-Research/issues/218


Admin, please take a look into this.


Essentially I believe it means that if you are Member of the Gridcoin Team then you can get 'paid' to crunch the
workunits if they allow this Project thru 'their' scrutiny process. Otherwise like the rest of us you crunch because you want too!

I was on the Gridcoin Team at one time and they DO 'pay' you, but you won't get rich or even make your electricity money back while crunching for the Gridcoin Team. My personal experience
obviously and your mileage may vary.
