JUSTUS2/Getting Started

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
