Creating an Interactive RStudio Session
- Rebecca Belshe
This tutorial will cover how to use RStudio on the Aloe supercomputer. The interactive RStudio graphical application is an ideal approach for new users as they become familiar with the supercomputer. This is also ideal for code that is being developed or tested before it is submitted as a batch job.
Using the Interactive RStudio Graphical Application
The interactive RStudio graphical application is available through the web portal. To access this application, follow these steps:
Connect to the web portal and log on with your credentials.
Select “Interactive Apps“ in the navigation bar then select “RStudio“.
You will be directed to a request form. This form will be used to request resources for your interactive session. An explanation of these resources can be found in this “Requesting Resources on Aloe“ guide.
Specify the resources needed for your job and select “Launch“.
You will be directed to a window with details about your job. Select “Launch RStudio“ and the interactive RStudio graphical application will open:
How will I know how many and which resources to use?
Learning to use the supercomputer, like learning how to use other new technologies in your life, will take trial and error. A good starting point is to start with one core for two hours in the interactive RStudio graphical application as you get familiar with the supercomputer. You can also request resources to replicate your current workstation to create a baseline. Through this trial and error, you will identify what resources can better improve your computation’s performance. See the “Requesting Resources on Aloe“ guide for additional tips.
