Once you’re allocated resources, you should see a prompt that displays the new node you’ve been redirected to. If you’re using SLURM, you can use a command like this: srun -time= -p -mem= -pty bash Next, we want to set up a compute or interactive node that we can use for long enough to get our work in RStudio finished. So that you know your HPC system indeed is set up for X11 forwarding and isn’t just ignoring the flag you offered it. But the reason I suggest this is that you can sift through all of that noise to look for a line that looks something like this: debug1: Requesting X11 forwarding with authentication spoofing. First, try logging into your remote HPC with XQuartz enabled, like so: ssh -v -X you’re not used to using the -v (verbose) flag when you log in, this will be an unwelcome spam to your screen. Okay, now that we’re through the prerequisites, we can start setting up an RStudio window on our remote HPC. Once you have conda set up, you can use the following command to set up an R environment that should work: conda create -n myRenv -c r r-essentials r-base rstudio r-lattice
#Xquartz ssh forwarding install#
While we’re at it, we should also install some dependencies that will come up in your use of R. My preferred method of doing this is via conda. The third prerequisite is that you need RStudio installed somehow on your HPC system.

If you’re on Mac, you’ll need to download XQuartz, and if you’re on PC, it’ll be Xming.

The X11-related software you’ll need on your computer differs based on whether you are a Mac or a PC. Namely, we’ll use XQuartz to visualize this incoming data stream, which is the second prerequisite. So we’re taking the visual output that the HPC can generate but doesn’t have the display to visualize, and sending it somewhere on our own computer. Your HPC system needs to be set up for X11 forwarding, which is a way to access the graphical window being spun up by the remote system (with access to all the files on that system) on your own computer. The first thing is the most important, and it’s a little bit out of your hands. The perhaps most frequent situations are visualizing/exploring data and debugging.įor this tutorial, you’ll need a few things. There are many occasions when doing “big data”-esque work on an HPC in which you may need access to an IDE. RStudio is a clean IDE that allows you to simultaneously view your filesystem, environment variables, R scripts, and console, and is all very specifically tailored to R, which is important in many cases ( R is an amazing but finicky language). And there are still a lot of reasons to use it, even if you’ve gotten used to something like Spyder or Jupyter. talk to your linux administrator about those if you get an error…however you should be good with X11 forwarding with the above.RStudio was once my favorite and most often-used IDE. You may need GTK2 fonts too if there are further issues with invoking BI clients. Once this works – you should be able to invoke all BI/HANA shell scripts which can give you a GUI.
Then we add the xauth to this while in sudo.Īdd the complete MIT-MAGIC-COOKIE-1 available outside of sudo within sudo using the xauth add ‘cookie’ command This can be accomplished by a simple touch command.
Here since the xauth file does not exist. this is because the xauths magic cookies are not available within sudo. Now the error has change to authorization. Get out of sudo and check the value of $DISPLAY. This error is because the display is not available after sudo and you have to export it. Now often after logging in to linux – folks have to do a sudo and if you try xeyes after a sudo you get Now if everything is right – typing xeyes on your putty prompt should bring up the ROLLING eyes Not mandatory but useful in troubleshooting.
Leave the remote X11 authentication protocol as the MIT-magic-Cookie-1Ĭheck if you have xeyes by typing ‘xeyes’. This might vary depending upon your linux distro. The instructions below are for Windows.Īt the OS level confirm that the X11FORWARDING has been set to YES in /etc/ssh/sshd_config. To enable GUIs on LINUX you have to setup X11 forwarding with putty.
