Bash in HPC

The training covers the basic use case for a supercomputer.

During this training, you will learn many useful Linux commands that will allow you to prepare and run a job on a Supercomputer. You will familiarize yourself with the Linux toolset to make your work on the supercomputer more convenient. The training covers basic Bash scripting.

This training was previously known as the "First Time on a supercomputer", but due to confusion about the title, we decided to change the name. This training does not provide an in-depth description on how to run a job on HPC. That is covered by Running Calculations the HPC way training provided at ACC Cyfronet AGH.

Level

Target audience

Training is intended for people who are familiar with the basics of Linux and haven't used a supercomputer yet. 

Agenda

1. Environmental variables and storage spaces - learning distinct features of the supercomputer; variables, env vars, export, $HOME, $SCRATCH, $USER, $PLG_GROUPS_STORAGE, bc;
2. file permissions - understanding ownership of files: ls -l, chmod;
3. transferring files to and from the supercomputer: tar, scp;
4. running a job and viewing results: sbatch, find, grep, mc;
5. scripting in bash: for, sleep, date, seq, subshell $();
