JUSTUS2/Getting Started

Here is a short list of things you may need to do first when you get onto the cluster

1 Basics

• log in to the cluster: JUSTUS2/Login
• get accustomed with the linux commandline:
  • introduction on the hpc wiki or
  • linux course at training.bwhpc.de

2 Running an Example with Preinstalled Software

• scientific software: read on how to load Software Modules
• continue reading until you found that there are example job scripts: Environment_Modules#Software_job_examples
• submit a sample job from a software as mentioned in the job example. Also see: JUSTUS2/Slurm
• monitor your job: JUSTUS2/Slurm#Monitoring_Your_Jobs

3 Running Your Own Calculations

• transfer your own data to the cluster: Data Transfer
• adapt the sample job script to run your own job

Note that your jobs should not write/read much on the lustre filesystem while the job runs, but either use the ram disk in /tmp or request /scratch if the space of the ram disk isn't sufficient. The Slurm Howto shows how to copy and clean up your data from /tmp or /scratch at the end of the job
