This page details the build of our [[DIGITS DevBox]]. There's also a page giving information on [[Using the DevBox]]. nVIDIA, famous for their incredibly poor supply-chain and inventory management, have been saying [https://developer.nvidia.com/devbo "Please note that we are sold out of our inventory of the DIGITS DevBox, and no new systems are being built"] since shortly after the [https://en.wikipedia.org/wiki/GeForce_10_series Titax X] was the latest and greatest thing (i.e., somewhere around 2016). But it's pretty straight forward to update [https://www.azken.com/download/DIGITS_DEVBOX_DESIGN_GUIDE.pdf their spec].

<onlyinclude>[[File:Top1000.jpg|right|300px]] Our [[DIGITS DevBox]], affectionately named "Bastard"after Lois McMaster Bujold's fifth God, has a XEON e5-2620v3 processor, 256GB of DDR4 RAM, two GPUs - one Titan RTX and one Titan Xp - with room for two more, a 500GB SSD hard drive (mounting /), and an 8TB RAID5 array bcached with a 512GB m.2 drive (mounting the /bulk share, which is available over samba). It runs Ubuntu 18.04, CUDA 10.1 (and CUDA 10 under conda)0, cuDNN 7.56.1, Anaconda3-2019.03, python 3.7, tensorflow 1.13, digits 6, and other useful machine learning tools/libraries.</onlyinclude>

But the parts ' cost is perhaps $4-5k now for a massive update to the original spec! So this page goes through everything required to put one together and get it up and running.

This looks good. The second card Check the hardware is the Titan RTX (see httpsbeing seen and what driver is being used with://devicehunt.com/view/type/pci/vendor/10DE/device/1E02). lspci -vk

You could install the driver directly now using, say, apt install nvidia-430. But don't! ====CUDA==== Get CUDA 10.1 and have it install its preferred driver (418.67): *The installation instructions are here: https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html*You can down load CUDA from here: https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1804&target_type=runfilelocal Essentially, first install build-essential, which gets you gcc. Then blacklist the nouveau driver (see https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#runfile-nouveau) and reboot (to a text terminal, if you have deviated from these instructions and already installed X Windows) so that it isn't loaded.

Install the driver!  apt install nvidia-driver-430 ====CUDA==== Get CUDA 10.0, rather than 10.1. Although 10.1 is the latest version at the time of writing, it won't work with Tensorflow 1.13, so you'll just end up installing 10.0 under conda anyway. *The installation instructions are here: https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html*You can down load CUDA 10.0 from here: https://developer.nvidia.com/cuda-10.0-download-archive?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1804&target_type=runfilelocalEssentially, first install build-essential, which gets you gcc.  Then run the installer script.and DO NOT install the driver (don't worry about the warning, it will work fine!): sh cuda_10.10.168_418130_410.67_linux48_linux.run  Do you accept the previously read EULA? accept/decline/quit: accept Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 410.48?

Finished copying samples. =========== = Summary = =========== Driver: Not Selected Toolkit: Installed in /usr/local/cuda-10.0 Samples: Installed in /home/ed, but missing recommended libraries Please make sure that - PATH includes /usr/local/cuda-10.0/bin - LD_LIBRARY_PATH includes /usr/local/cuda-10.0/lib64, or, add /usr/local/cuda-10.0/lib64 to /etc/ld.so.conf and run ldconfig as root To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-10.0/bin Please see CUDA_Installation_Guide_Linux.pdf in /usr/local/cuda-10.10/doc/pdf for detailed information on setting up CUDA. ***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 384.00 is required for CUDA 10.0 functionality to work. To install the driver using this installer, run the following command, replacing <CudaInstaller> with the name of this run file: sudo <CudaInstaller>.run -silent -driver Logfile is /vartmp/log/cuda-installercuda_install_2807.log

Fix Now fix the paths. To do this for a single user do: export PATH=/usr/local/cuda-10.10/bin:/usr/local/cuda-10.1/NsightCompute-2019.10${PATH:+:${PATH}} export LD_LIBRARY_PATH=/usr/local/cuda-10.10/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

Start But it is better to fix it for everyone by editing your environment file: vi /etc/environment PATH="/usr/local/cuda-10.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games" LD_LIBRARY_PATH="/usr/local/cuda-10.0/lib64" With version cuda 10.0, you don't need to edit rc.local to start the persistence daemon:

This should be run at bootInstead, so: vi /etc/rc.local #!/bin/sh -e /usr/bin/nvidia-persistenced --verbose exit 0 chmod +x /etc/rcruns as a service.local Verify the driver: cat /proc/driver/nvidia/version

Make the samples in:... cd /usr/local/cuda-10.10/samples

Change into the sample directory and run the tests: cd /usr/local/cuda-10.10/samples/bin/x86_64/linux/release

And yes, it's a thing of beautyEverything should be good at this point! ===X Windows=== Now install the X window system. The easiest way is: tasksel And choose your favorite. We used Ubuntu Desktop. And reboot again to make sure that everything is working nicely.

Then follow https://github.com/NVIDIA/nvidia-docker#quick-start to install docker2, but change the last command to use cuda 10.10

docker run --runtime=nvidia --rm nvidia/cuda:10.10-base nvidia-smi

dpkg -i libcudnn7_7.56.1.1034-1+cuda10.1_amd640_amd64.deb dpkg -i libcudnn7-dev_7.56.1.1034-1+cuda10.1_amd640_amd64.deb dpkg -i libcudnn7-doc_7.56.1.1034-1+cuda10.1_amd640_amd64.deb

==Video Driver Issue=VNC=== In order to use the graphical interface for Matlab and other applications, we need a VNC server.  First, install the VNC client remotely. We use the standalone exe from TigerVNC.  Now install TightVNC, following the instructions: https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-ubuntu-18-04  cd /root apt-get install xfce4 xfce4-goodies As user sudo apt-get install tightvncserver vncserver set password for user (ailia) vncserver -kill :1 mv ~/.vnc/xstartup ~/.vnc/xstartup.bak vi ~/.vnc/xstartup #!/bin/bash xrdb $HOME/.Xresources startxfce4 & vncserver sudo vi /etc/systemd/system/vncserver@.service [Unit] Description=Start TightVNC server at startup After=syslog.target network.target [Service] Type=forking User=uname Group=uname WorkingDirectory=/home/uname PIDFile=/home/ed/.vnc/%H:%i.pid ExecStartPre=-/usr/bin/vncserver -kill :%i > /dev/null 2>&1 ExecStart=/usr/bin/vncserver -depth 24 -geometry 1280x800 :%i ExecStop=/usr/bin/vncserver -kill :%i [Install] WantedBy=multi-user.target Note that changing the color depth breaks it! To make changes (or after the edit) sudo systemctl daemon-reload sudo systemctl enable vncserver@2.service vncserver -kill :2 sudo systemctl start vncserver@2 sudo systemctl status vncserver@2 Stop the server with sudo systemctl stop vncserver@2 Note that we are using :2 because :1 is running our regular Xwindows GUI. Instrucions on how to set up an IP tunnel using PuTTY: https://helpdeskgeek.com/how-to/tunnel-vnc-over-ssh/ ====Connection Issues====

After logging into Coming back to this, I had issues connecting. I set up the tunnel using the saved profile in puTTY.exe and checked to see which local port was listening (it was 5901) and not firewalled using the box sometime laterlistening ports tab under network on resmon.exe (it said allowed, not restricted under firewall status). VNC seemed to be running fine on Bastard, it seems and I tried connecting to localhost::1 (that is 5901 on the video drivers are no longer loadinglocalhost, presumably as a consequence of some update or somethingthrough the tunnel to 5902 on Bastard) using VNC Connect by RealVNC. The connection was refused.

I checked it was listening and there was no firewall: nvidianetstat -settings --query FlatpanelNativeResolutiontlpn tcp 0 0 0.0.0.0:5902 0.0.0.0:* LISTEN 2025/Xtightvnc ufw status ERRORStatus: NVIDIA driver is not loadedinactive

The localhost port seems to be open and listening just fine: cd Test-NetConnection 127.0.0.1 -p 5901 So, presumably, there must be something wrong with the tunnel itself. '''Ignoring the SSH tunnel worked fine: Connect to 192.168.2.202::5902 using the TightVNC (or RealVNC, etc.) client.''' ====Later Notes==== =====Change the resolution===== I came back and changed the resolution to make it work on one of my portrait desktop monitors.See https://www.tightvnc.com/vncserver.1.php As root: vi /etc/systemd/system/vncserver@.service Change line: ExecStart=/usr/localbin/vncserver -depth 24 -geometry 1440x2560 :%i (Note that the size is 2160x3840 divide by 150%). Leave the color depth as it says elsewhere that changes are bad. systemctl daemon-reload systemctl enable vncserver@2.service As Ed: vncserver -kill :2 sudo systemctl start vncserver@2 sudo systemctl status vncserver@2 Exit full screen with ctrl-alt-shift-f. =====Cut And Paste===== Also, try to fix the cut-and-paste issue. See, for example, https://unix.stackexchange.com/questions/35030/how-can-i-copy-paste-data-to-and-from-the-windows-clipboard-to-an-opensuse-clipb As root: apt-get install autocutsel vi ~/.vnc/xstartup #!/bin/bash xrdb $HOME/.Xresources autocutsel -fork startxfce4 & Though this might have been working fine anyway. Just change the terminal and all will be well. =====Use XFCE terminal===== Change Settings: Preferred Applications -> Utilities -> Terminal to XFCE Note that this seems to fix everything but the instructions for customizing the menu are here: https://wiki.xfce.org/howto/customize-menu cat /etc/xdg/menus/xfce-applications.menu ===RDP=== I also installed xrdp: apt install xrdp adduser xrdp ssl-cert #Check the status and that it is listening on 3389 systemctl status xrd netstat -tln #It is listening... vi /etc/xrdp/xrdp.ini #See https://linux.die.net/man/5/xrdp.ini systemctl restart xrdp This gave a dead session (a flat light blue screen with nothing on it), which finally yielded a connection log which said "login successful for display 10, start connecting, connection problems, giving up, some problem." cat /var/log/xrdp-sesman.log There could be some conflict between VNC and RDP. systemctl status xrdp shows "xrdp_wm_log_msg: connection problem, giving up". I tried without success: gsettings set org.gnome.Vino require-encryption false https://askubuntu.com/questions/797973/cudaerror-problem-connecting-windows-10-rdp-into-xrdp vi /etc/X11/Xwrapper.config allowed_users = anybody This was promising as it was previously set to consol.1 https://www.linuxquestions.org/questions/linux-software-2/xrdp-under-debian-9-connection-problem-4175623357/#post5817508 apt-get install xorgxrdp-hwe-18.04 Couldn't find the package... This lead was promising as it applies to 18.04.02 HWE, which is what I'm running https:/samples/binwww.nakivo.com/x86_64blog/how-to-use-remote-desktop-connection-ubuntu-linux-walkthrough/release dpkg -l |grep xserver-xorg-core ii xserver-xorg-core 2:1.19.6-1ubuntu4.3 amd64 Xorg X server - core server Which seems ok, despite having a problem with XRDP and Ubuntu 18.04 HWE documented very clearly here: http://c-nergy.be/blog/?p=13972 There is clearly an issue with Ubuntu 18.04 and XRDP.The solution seems to be to downgrade xserver-xorg-core and some related packages, which can be done with an install script (https://deviceQueryc-nergy.be/blog/?p=13933) or manually. But I don't want to do that, so I removed xrdp and went back to VNC! apt remove xrdp  CUDA Device Query ===Other Software=== I installed the community edition of PyCharm: snap install pycharm-community --classic #Restart the local terminal so that it has updated paths (Runtime APIafter a snap install, etc.) version /snap/pycharm-community/214/bin/pycharm.sh On launch, you get some config options.
