Introduction to the LUNARC User Manual

Welcome to the LUNARC User Manual! This guide is designed to help new and experienced users make the most of LUNARC's High Performance Computing (HPC) resources.

Efficient management of compute resources is essential for successful HPC usage. LUNARC uses SLURM (Simple Linux Utility for Resource Management) as its job scheduler and resource manager. To run your programs, you will need to describe to SLURM: - The resources your program requires (cores, memory, time, etc.) - The program or script to execute - Any command-line arguments your program needs

SLURM also provides tools for monitoring and managing your jobs during execution.

How to Use This Manual

This manual is organized into several key sections:

1. Job Submission
   Learn how to submit jobs to the cluster, including resource requests and job options.

2. Example Scripts
   Find ready-to-use scripts for common use cases, such as serial and parallel jobs.

3. Modules and Software
   Understand how to load and manage software environments using the module system.

4. Interactive Computing
   Explore options for interactive sessions, including the Desktop on Demand and command-line access.

5. Quick Reference & Glossary
   Access command summaries and definitions of common HPC terms.

Tip

If you are new to LUNARC or HPC, start with the Job Submission and Example Scripts sections.
