Since you are using Win10 it's probably a driver problem and Windows replaced the one that can crunch with one that can't, it's very common for that to happen after Win10 updates.

Also I noticed your 1070 on another machine isn't using the optimized codes, your 1070 is doing workunts in:
1,470.26 0.30 37,959.45 Collatz Sieve v1.30 (opencl_nvidia_gpu) windows_x86_64

I have a 1060 that is using the optimization codes and is doing them in:
698.90 0.88 28,776.25 Collatz Sieve v1.30 (opencl_nvidia_gpu) windows_x86_64

It's less credits per workunit but I am doing 2 workunits to your 1 so am getting lots more credits.

You will have to look in the Number Crunching, Optimizing the Apps thread for how to do it, it's really easy, and the very next workunit after you put the codes in will start using them.

You were right Mikey! even though I thought I'd stopped GPU updates thru the registry!!!

Now to do the optimizing ;)

Do you have a cc_config.xml file in the Boinc directory with this line in it:

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

If not use a text editor to make the file and put it in there, then reboot and see if Boinc see both of them.
If Boinc still doesn't see them you may have to load the drivers again for the 2nd gpu.

Which Boinc directory? I can't write into the one under Programmes, and putting it in the directory where all the project files are does nothing. I have two identical NVIDIA GTX1070 Ti GPUs, they both work for Moo Wrapper and Primegrid.

It goes in c:\program data\boinc\????.collatz as long as you did a standard install and didn't change the defaults.

After you get it working on both of them you will want to go the number crunching thread and one of the oldest threads under 'optimizing the apps' so you can max out your 1070ti's, I think it's back on page 3 like post #7 that has the codes. The same thread tells you where to put them, but don't do it before you start crunching units or it won't work.

Thanks,I'll let you know how I get on, I had success in writing the file into the right place, (typical windo$e machine had told me I didn't have "the authority!"), re-read the config files OK, just have to wait for the machine to need more GPU jobs now. I'll go into the fine tuning once the jobs start coming in, although in all honesty I don't need more heat in my apartment.
Windoze has always been a mystery for me drives me mad.

Here I go again! copied my cc_config.xml file from one machine onto a new W10 machine, and Boinc Manager says it can't find it, doesn't exist! Contents:

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

What am I doing wrong? I'm at my wits end, machines and Boinc heading for the dump soon!

Some of your workunits are part of the ongoing problems of empty data files that is slowly being worked thru, some though look like you are aborting them before they even try to run. SOMETIMES it says 'aborted' when in reality the workunit was withdrawn by the Project itself so if you aren't aborting them yourself that's probably what's going on there.

Did you put the cc_config file in the c:\program files\boinc folder? Or did you put it somewhere else? App_config files go into the Project folders while cc_config files affect all of Boinc so just go into the Boinc folder. Did you use Notepad to make the file and save it as an .xml file? If you aren't careful it's easy for Windows to add a .txt after the .xml making the file unusable. If you used a word processing program they always add things inside the coding that Boinc can't read and thinks the files is unusable.

Thanks for your reply.

The copy of the file (in my original post) is copy & paste from notepad, I've retyped it several times, when I try to save it in the correct place it says I don't have "administrator" rights to do so, although the file gets listed in the directory! I re-read the config file & Boinc manager says it isn't there. I avoided the ".txt" trap from long experience.

(P.S. I hate computers, just for now. :( )

Okay move the file to someplace else and go into the Boinc Manager and click on Options, Event Log Options and select some things, around 6 or so it doesn't matter what just things that look interesting for now, then click Save at the bottom of the box. That should create a cc_config.xml file that Boinc sees which you can then edit by right clicking on it and selecting use Notepad from the list. Once you are editing the file paste your lines back in in the right place, for me I added another Options section just above the </cc_config> line that ends the file and added the lines I wanted and then closed the new options sections and then saved it. Boinc then re-read it just fine when I asked it to and it's doing what's it supposed to do.

It's me, again! Having got nowhere with windows10 I threw it away and I've installed Linux Debian "buster" (taken two days even with the help of my mate in Malta on the telephone for six or seven hours). Then I installed BOINC and chose some projects to run and up comes your message. So I've followed your instructions and am sending the machine down for a reboot now.

To be continued.............

Message 2177 - Posted: 13 Dec 2019, 18:48:11 UTC - in response to Message 2174.  

La suite! Thinking that the reason for the failure of the BOINC manager to write a new cc_config.xml file was that I needed to restart BOINC. So I sent the machine down for a reboot and when it came back up it was without the graphics interface, i.e.I have only "Command Line" access to the machine, Then things went really pear shaped because the machine started overheating and started shutting down. I can install a command line manager for BOINC but even with the side panel off the case the machine is still getting too warm. With my original cc_config.xml file the "event log" showed that it was being found and also the big new shiny NVIDIA 2070 Super GPU, but not the GTX 750 Ti.

Something is wrong,

The screens connected to the smaller card are getting sync signals but no video. One reason for the 2070 GPU was to run my new 32" 4K UHD screen which it does fine. Previously I had the 3 screens connected to just the smaller card but the big screen wouldn't run at full resolution, so I knocked it back to standard HD 1920x1080 and everything was fine till the HDD went down, all this was running Linux, so I bought a new hard drive (heavy duty) and decided to add the extra GPU to feed the big screen, when it came back from the rebuild (in a nice new bigger case with more ventilation) the shop had installed a temporary version of W10, the screens all worked but not GPU in BOINC, which was I started all this correspondence about the cc_config.xml file.

So!

I've turned it off for the weekend and will think about things, I can boot the machine, login as root and kill BOINC and then see if there is anything I can do. It's supper time. Very many thanks for all your help I really am extremely grateful. Malcolm.

I have the machine running, needs a 80cm fan where the side panel normally is to allow it to function, but what the hell?
I've installed a command-line BOINC manager which is fine.
Only finds the big GPU, so could you suggest an extra line that I can add to cc_config.xml please? I can write the file with no problems, your suggested manner in the BOINC graphical manager didn't work for me.
I'm wondering if we should move this conversation to the Linux area now.

You need a cc_config.xml file with these lines in it:
<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

I am NOT a Linux guy though so have no clue how to do that without the gui interface, my Linux installs are very basic and once they are running I just leave them alone. I often even turn off the updates on them as they are just crunchers. So YES moving this to a place where more Linux people would see it might help alot.

I've found a list of the options for cc_config and added a line <use_certs>1</use_certs> just below the "use all gpus" line and the file got read on rebooting, wonderful, now it says the 440.44 driver that is installed for the NVIDIA 2070 Super is not suitable for the GTX 750 Ti. Hate everything. But this is a problem for my mate in Malta along with getting the graphical interface back, meanwhile the machine is crunching merrily away so all is well.

Many thanks for your help, you've been very patient with me and my machine. Good weekend to you, Malcolm

You can load another driver for the 750Ti if you want too in Windows and it will use the one it needs too for the gpu, I have no clue in Linux.
