GACRC Training
The GACRC regularly hosts training sessions on a number of subjects relevant to the use of our computational and storage resources. Scheduled trainings will be announced through the GACRC mailing list.
NOTE: New users are required to attend a Sapelo2 cluster introductory training session and information about that will be sent once an account is requested.
Regular Training Announcement
In December 2024, the GACRC is hosting 7 training sessions (3 Linux basics and 3 Sapelo2 cluster new user trainings and 1 Using Sapelo2 Cluster at the GACRC, Part II training).
We will offer:

Linux Training for Linux-inexperienced Cluster New Users
The Sapelo2 High Performance Computing (HPC) cluster runs a headless Linux distribution as the operating system on each of its constituent nodes. The term headless refers to the fact that these nodes do not have a desktop graphical user interface (GUI) installed by default. Graphical desktop environments consume resources that analyses could otherwise use, so users employ a command-line interface (CLI) instead. To interact with these resources, users connect to a remote terminal via SSH and execute commands.
The Linux Training workshop provides hands-on practice of the fundamental Linux commands necessary to interact with HPC resources.
Prerequisite: Please watch the introductory videos on Linux, basic Linux terms, and Linux Paths and Directories (total ~17 minutes) before attending the training workshop.
Training Goals:
1. Understand fundamental concepts of Linux working environment (filesystem hierarchy, path, PATH, etc.)
2. Know how to use Linux common commands (ls, cd, pwd, cat, more, nano, mkdir, rm, cp, mv, etc.)
3. Understand what is Linux bash shell and know how to make a simple Linux script and run it in Linux environment
| Title | Date/Time |
