1 General Workflow of Running a Calculation
On a compute cluster, you do not simply run log in and your software, but you write a "job script" that contains all commands to run and process your job and send this into a waiting queue to be run on one of several hundred computers.
How this is done is described in a little more detail here: Running Calculations
2 Get access to the cluster
Follow the registration process for the bwForCluster. → How to Register for a bwForCluster
3 Login to the Cluster
Setup service password and 2FA token and login to the cluster. → Login JUSTUS2
4 Get Accustomed with the Linux Commandline
HPC Wiki (external site) → Introduction to Linux Commandline
Training course → Linux course on training.bwhpc.de
5 Transfer your data to the cluster
Get familiar with available file systems on the cluster. → File Systems
Transfer your data to the cluster using appropriate tools. → Data Transfer
6 Find information about installed software and examples
Compiler, Libraries and application software are provided as software modules. Learn how to work with software modules. → Software
Run sample script from a pre-installed software (Software job examples in the page above)
7 Submit your application as a batch job
Get familiar with available nodes types on the cluster. → Hardware and Architecture
Submit and monitor your jobs with Slurm commands. → Batch System Slurm
8 Acknowledge the cluster
Remember to mention the cluster in your publications. → Acknowledgement
