I think I have somewhere around 200 +- ghosts. I will see if I can do it after I get the GTX 750ti's moved in

Raistmer's SoG app isn't as highly parallelized as Petri's. Though we have now tempted Raistmer over to the "dark side" and he is trying out and investigating Linux to learn the advantages of that environment with the Linux drivers I assume to help further his SoG app over in the Windows environment. So possibly some performance enhancements eventually for the SoG app or maybe a completely new app for Windows users.

That would be great!!! If he can come up with some more speed ups for the Windows gpu tasks. We have a lot of Windows machines active with Nvidia gpu's. If he comes up with even a 10% on average speed up in the processing that is moved into production it would increase the processing massively.

Ok. this morning I did something really stupid. I saw there some live patches for Lubuntu on my machine. I missed there were upgrades to the ppa nvidia driver. I ended up trashing 99 wu. I've been quota'd, until I can complete another wu. Maybe tomorrow I will get a cuda wu.

The Nvidia driver update shouldn't have caused any issues. Unless you did not reboot after the update to load them. From your errors it looks like the drivers were missing when you tried to run the tasks.

I believe the wu's were trashed between the time the new drivers were loaded and the reboot. It was my mistake that I did not stop BOINC before driver updates. I was not paying attention to what I was doing, and it bit me. I learned something today.

The ones in the repository (of most Linux distributions) don't work properly :-( So you have to get them from the nVidia website, make sure you get the right ones for both your distribution and card. the other is via the PPA channel - as I've not actually used this I've no idea how well/badly it works..... (Kieth will no doubt be around soon to tell you exactly how & why - he swears by it and I know others who swear at it - typical Linux).

I mostly swear by it, not at it. So far the PPA channel has been very easy for me to use with Ubuntu and its derivatives.

If you open a terminal and use these commands followed up with the "install drivers" under the update app's tab you can select the driver you want to install and go on about your merry business. Yes, it takes a while to install. And yes, you need to reboot the system before the drivers are fully installed.

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update

Basically you need a 3.96 or higher driver to run the Cuda91 type gpu apps. I have been using 4.10 along with several others, with no driver problems. If you want all the bugs patched you probably should use "4.18"

HTH,

You have to remember that the Nvidia Linux drivers are kernel mode drivers. Any driver install or driver update has to recompile the kernel with the new drivers. So if you see a driver update notification through the Software Updater for either the standard repository or ppa repository drivers, know that the install has to recompile the kernel to put the driver in. So until you reboot the system you won't be running the new updated version. Also the update may leave you in a quasi state where the new drivers are installed but not accessible so the system temporarily uses the basic Nouveau drivers in between the time you installed the drivers and reboot. Those drivers don't support compute.

I did not know the details of how linux works, knowing this helps a lot.
