This will allow your laptop/desktop to access the compute node comptue-YYY on port XXXXX (in the above example, the port used was 12345 and the compute node used was compute-012).įor Windows based laptops/desktops, or from the SAFE Desktop: At this “ssh>” prompt you activate the tunnel by typing -L XXXXX:compute-YYY:XXXXX. The ~C will likely not show up, but you should see an “ssh>” prompt as a result. The ~C is used to send an interrupt to your ssh session. You will need to perform one step to enable access to this Rstudio Server from your local laptop/desktop specifically, you will need to add a tunnel to your existing ssh session to the JHPCE cluster. When you are finished using Rstudio Server, type -C
3) When prompted for Username, enter your JHPCE ID: jdoe1Ĥ) When prompted for Password, enter your JHPCE password. * Mac or Linux Desktop users, please type:Ģ) From the browser running on your local system or SAFE desktop, go to: Last login: Wed May 1 17:02:29 2019 from jhpce01.cm.cluster
An example of running “jhpce-rstudio-server” is provided below. To use Rstudio Server, start by qrsh-ing into a compute node, then run “ jhpce-rstudio-server”, and then follow the steps displayed. When the “ jhpce-rstudio-server” program is run, it starts an instance of the Rstudio Server web server within a Singularity image on a unique port number, and then provides instructions for setting up an ssh tunnel to allow you to access Rstudio Server from your local system. On the JHPCE cluster we have put together a script called “ jhpce-rstudio-server” which will allow you to run your own personal copy of Rstudio Server and access it from a browser on your laptop or desktop. Rstudio Server is a web based environment for developing R programs.
