Welcome to UF Research Computing! This page is intended to help new and uninitiated users understand and use UFRC resources. Be sure to check out our training schedule if you'd like help getting started in person!
Note that for any given command,
<your_username> should be replaced with your GatorLink username.
For example, if your are referencing the command
ssh <your_username>@hpg2.rc.ufl.edu and your Gatorlink username is smith, you would use the command:
Linux / Unix
Transferring your files
The simplest method for file transfer is through the use of graphical file transfer client. UFRC recommends:
After you have chosen and downloaded a client, configure the client to connect to
sftp.rc.ufl.edu, using your username and password to log in.
SFTP and Rsync file transfers should use the servers dedicated to these transfer types, which are
Globus is another mechanism for transferring data to and from HiPerGator. See the Globus page for setup and configuration information.
Editing your files
Several methods exist for editing your files on the cluster.
- vi - The visual editor (vi) is the traditonal Unix editor; however, it is not necessarily the most intuitive editor. View a tutorial for using vi
- emacs - Emacs is a much heavier duty editor, but again has the problem of having commands that are non-intuitive. View a tutorial for using emacs
- pico - While pico is not installed on the system, nano is installed, and is a pico work-a-like.
- nano - Nano has a good bit of on-screen help to make it easier to use.
You can also use your favorite file editor on your local machine, and then transfer the files to the cluster afterwards. A caveat to this is that files created on Windows machines usually contain unprintable characters, which may be misinterpreted by Linux command interpreters (shells). If this happens, there is a utility called
dos2unix that you can use to convert the text file from DOS/Windows formatting to Linux formatting.
Using installed software
Running graphical programs
Please see the GUI Programs page for information on running graphical user interface applications at UFRC.
Scheduling jobs using SLURM
UFRC uses the Simple Linux Utility for Resource Management, or SLURM, to allocate resources and schedule jobs. Users can create SLURM job scripts to submit jobs to the system. These scripts can, and should, be modified in order to control several aspects of the job, like resource allocation, email notifications, or output destination:
- See the Annotated SLURM Script for a walk-through of the basic components of a SLURM job script
- See the Sample SLURM Scripts for several SLURM job script examples
To submit a job script from one of login nodes via hpg2.rc.ufl.edu, you would use the following command:
$ sbatch <your_job_script>
To check the status of submitted jobs, you would use the following command:
$ squeue -u <your_username>
View SLURM_Commands for more useful SLURM commands.
