Quest Quick Start Guide
This page provides help getting started with connecting to, accessing software on, and submitting jobs to the Quest computing cluster.
See our Introduction To Quest video for a 90-minute interactive tutorial that takes you step-by-step through logging into Quest, editing a job submission script, launching and monitoring a job, as well as a deep dive into how Quest works.
Once you've logged into Quest, you will begin in your Home directory: /home/<NetID>. The home directory has 80GB of storage and is backed up nightly. Backups are kept for two weeks.
Note that throughout this guide, items in angle brackets (<>) in example commands are parameters you need to change relative to your account and work. Do not include <> around the values you substitute into the commands.
You can navigate to the projects directory of your allocation by typing
Project directories are not backed up. You can check how much storage you have by typing
If you are not familiar with using command line, this tutorial, Learning the Shell, will help you learn the basics.
Moving Files onto Quest
Software available on Quest
Many applications are available on Quest. You can access them through modules, which modify your environment to enable you to run the software. Quest uses modules so that multiple versions of the same software can be available for different users.
See Modules Software Environment Manager for examples of loading software with modules and a list of common commands.
If you would like additional software packages installed on Quest, please fill out the Software Installation Request Form. Additionally, you can also install software in your own home or project directories. For details, review our Installing Software on Quest page.
Running Jobs on Quest
When you first log in to Quest, you will be on one of the four login nodes: quser21, quser22, quser23, or quser24. From the login nodes, you can submit jobs to the compute nodes, edit files, and perform small test jobs. Login node use is limited to 4 cores and 4 GB of RAM per user.
To take advantage of Quest's computing power, jobs can be submitted to the compute nodes in two ways: Interactive jobs, which are particularly useful for GUI applications, or Batch jobs, which are the most common jobs on Quest. Interactive jobs are appropriate for GUI applications like Stata, Visit, Paraview, etc., testing and prototyping of programs, running jobs with small core counts (< 6), and for short duration jobs. Batch jobs are appropriate for jobs with no GUI interface, large core counts, or long duration.
See Submitting a Job on Quest for more details, example job submission commands, and an example of a submission script.
