check ebay or facebook marketplace or other normal online markets.

K. Have checked there. Thought checking here I was more likely to find retired GPU hardware.

Good news. My hope is that somehow the ever annoying download issue will be gone when the new server is fully operational.

I am the only user of this PC. And it happens even when I am working on it. Driver updated - no change, GPU clock lowered by 200Mhz - no change. Folding@home works flawless. I have no idea what else I could do.

Windows at times has video driver timeout issues with XP, Vista, 7, 8 and 8.1 but that was with ATI cards. If you're using Win10 I have no experience with that OS. Never heard of it happening with Nvidia but that doesn't mean it couldn't. Try this and see if it helps. If it doesn't work it should not affect your computer in any way but to be super safe and eliminate "murphy's law" you could image your drive before you start if it would make you more comfortable. I've shown this fix many times to others without a single problem reported.

Copy and paste ALL of the text below as is into notepad. Rename the file timeoutfix.reg(or another name if you like). Now double click on it. You'll be prompted about adding files to the registry. Just click yes on any that appear. Now restart your computer. If your strange behavior stops then it was a timeout issue. If not then it's something else. If it doesn't work you can always go back and delete the reg entries if you're not comfortable leaving them there.

Linux app is live now.

What driver version is needed to use the CUDA8.5 (Linux) app?

The newest I could find for Linux is 367.44. I'm currently using 367.35 and the completed tasks I have show v9.14 (CUDA 80) as the app. Don't know if the newest driver would make use of 8.5 but since I've had too many gnarly experiences with video driver updates I'm not going to play guinea pig on this one. Maybe someone who has already updated to 367.44 can chime in.

Strange. My 1070 does not get better than 90% and the 1080 is even worse, maybe 75%. No matter how many tasks and the CPU/GPU ratio. As if the algorithm is not yet Pascal optimized.

But this gets off topic a little... maybe I should bring that question forward somewhere else.

FWIW my 1060 runs @ 95% with 2 tasks at a time at stock settings. What's truly amazing is that according to my UPS it's only pulling 45 watts.

Manually managed the hanging download issues and ran a few tasks. 4 short tasks completed in 464-537 seconds but another listed as a short task took 13,764 seconds. What's up with that?
GTX 1060 at stock settings, Ubuntu 16.04 LTS, driver 367.35.

Upon further inspection it seems that the longer running task had 5 million steps where the other 4 had only 250k.

Just had a short WU on my 1080 go for 9 hours and it was at 50% done. the GPU was idling. Other Pascal units had worked flawlessly. I aborted it and gave it a new one and it works again.


Same problem here. 76% for long time, GPU and CPU idle.


I still have this problem with maybe 10% of WU. Only restart helps - they are starting from 0% and crunching without problems. But I cant manually control it 24/7...

Have you tried suspending the stalled task and then resuming it? POEM used to do the same thing and suspending/resuming usually got the task moving again.

Yes they are and why they haven't been fixed is beyond ridiculous and reflects very badly on this project IMHO.

Maybe I'm overreacting but there are just too many issues with seeming simple remedies for me. Since I'm already in the process of scaling back my DC operation it doesn't really matter.
With that said, I have 3 SuperMicro dual socket boards with Xeon ES V4 CPUs that will be going up for sale. 2 are 28c/56t and 1 is 36c/72t. Won't go into all the details now. If there's anyone here interested PM me and we'll discuss things.

The problem is the downloads start and then stop and after whatever time elapses it tries again and it keeps doing the same thing over and over until all the files are received sometimes taking hours. This happens on all 4 of my machines with Nvidia cards and this project is the ONLY one that I run that gives me this issue. There is no <http_transfer_timeout>3000</http_transfer_timeout> tag in my cc_config file but I just added one. We'll see what happens but I'm not very optimistic.

Frequent but usually only for a few seconds. Long enough to wreak havoc with computers. You should be thankful that you live in an area that's more reliable. The proof is that there's about a 50% failure rate when this happens. Zoltan has posted about the problem too. If you won't believe anyone else, maybe you'll believe him. BTW, other than some factory OCs, none of my cards are OCed. In fact some are down-clocked.

A quality UPS would solve that issue if you could do it. We have momentary glitches and surges where I live also. I bit the bullet and put UPSs on all 8 of my DC machines 1 at a time. Even put 1 on my fridge after a surge took out a $600 control board but that's another story.

When I first installed 16.04 I was using a 750Ti and I installed the 361 driver from the repository. When I tried to install my 1060 I couldn't get it to boot. I put the 750 back in and started searching. The 367.27 driver is needed for the 10xx cards. I also found it helped me to install synaptic package manager first.
I used the following commands to get started with the video drivers.

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-367 nvidia-settings


I then reinstalled the 1060 and it booted but there were still some issues. Installing the 367 driver did not install the needed OpenCl or CUDA libraries. I used synaptic package manager to install them. Now we're almost done.

Add the unprivileged boinc account to the video group

sudo usermod -a -G video boinc

Move BOINC start-up to the end of the start-up processing.

sudo update-rc.d -f boinc-client remove
sudo update-rc.d boinc-client defaults 99


Without nvidia-modprobe installed boinc will not find the GPU

sudo apt-get install nvidia-modprobe <-- when I did this I found that it was already installed YMMV

sudo modprobe nvidia_uvm

sudo service boinc-client restart

That's it but in some cases a reboot is needed. Hope this will help someone. My 1060 now happily runs POEM and Einstein. Patiently waiting for support here
You can find more driver info here.

Each distribution/version of Linux has different features, terminal commands and add ons which makes it almost as difficult moving from one distribution to another as it is to move from Windows to Linux. However, Ubuntu 6.04-x64 is a Long Term Support distro, so it's something you can stick with for longer. While the command lines might have changed somewhat, again, the GUI updates (via the Ubuntu Sortware icon and Sortware & Updates in System Settings) are encouraging.
At present 6.04-x64 LTS works for GPUGrid crunching due to the driver support for GTX900 series GPU's. The question at the back of my mind is will it support NV's GTX1000 series GPU's?

http://www.omgubuntu.co.uk/2016/06/top-5-terminal-commands

http://manpages.ubuntu.com/manpages/xenial/man8/


16.04 does support the 10xx series GPUs. It was a minor PITA(probably more so for me being the Linux noob) to get it working. I can post what I did later if that will help. Just waiting for GPUGrid to support them.
Thanks for the links.

I copied the gui_rpc_auth.cfg from the /etc/boinc-client folder but I was not able to paste it into the home directory. The paste option was greyed out which means I have a permissions issue. Did a lot of searching and tried some terminal commands but have not found an answer yet.


Here is a more complete list of what I do to allow access to /etc/boinc-client.

Note that I copy a modified "gui_rpc_auth.cfg" into that folder, but you may not need to modify it. Also, it allows for creating (or changing) a "cc_config.xml" file, if you need to do that. I also use a "remote_hosts.cfg" file to allow access over the LAN, but you may not need it.

I have also included the commands to allow access to /var/lib/boinc-client, where the project folders are located. You will need that to copy an "app_config.xml" file into the GPUGrid project folder, for example.

-> Just replace "user_name" with you actual user name.

Join the root group: sudo adduser user_name root
Join the BOINC group: sudo adduser user_name boinc

Allow group to read, write and execute in /etc/boinc-client folder: sudo chmod -R g+rwx /etc/boinc-client
Allow group to read, write and execute in /var/lib/boinc-client: sudo chmod -R g+rwx /var/lib/boinc-client
Reboot

Copy “gui_rpc_auth.cfg” to /etc/boinc-client folder
Copy “remote_hosts.cfg” to /etc/boinc-client folder
Copy “cc_config.xml” to /etc/boinc-client folder
Copy "gui_rpc_auth.cfg" to the home directory
Reboot

Copy the "app_config.xml" files to the project folders in /var/lib/boinc/

That fixed it. Can't thank you enough. For someone who claims to be new at Linux you fixed something I've searching for weeks. Where did you come up with the info?
Thanks again.
David
