Running GROMACS efficiently on LUMI workshop 2024

This course gives practical tips on how to run GROMACS simulations efficiently on LUMI-G, i.e. on AMD GPUs. The participants will learn how to assess and tune GROMACS performance.  In addition the course provides an overview on LUMI architecture, GROMACS heterogeneous parallelization, with a special attention to AMD GPU. The event is organized by BioExcel in collaboration with CSC and PDC

Target Participants

These sessions are aimed at GROMACS users, specifically interested in running efficient GROMACS simulation on LUMI-G and understanding how to tune and to assess GROMACS performance. After the course the participants should have the skills and knowledge needed to efficiently use GPU resources in GROMACS simulations and tune and assess GROMACS performance.

Prerequisites

Participants are required to;

• be familiar with molecular dynamics simulation and have working knowledge of GROMACS. Note: The fundamentals of molecular dynamics simulation or basic usage of GROMACS are not covered in this course.
• have experience in basic Linux/Unix skills, understand basic batch scripts and hands-on experience in using HPC systems. Ability to use the command line: navigate files and directories through shell commands, create/move/delete files and directories, construct command pipelines, edit/run shell scripts, use basic Slurm commands, submit job in a queue, find further help about the scheduler.
• have awareness of differences between hardware components (i.e. GPU vs CPU, memory and storage) Please consult the following materials, if you’re uncertain of your Linux or GROMACS skills:
  • Lectures on the basis of molecular dynamics simulation (videolinks: part I, part II)
  • MD with GROMACS tutorials (link)
  • Linux commands, bash shell, a quiz and a link to intro course
  • Introduction to HPC system (link)

Topics

• LUMI architecture
• GROMACS heterogeneous parallelization
• AMD GPU support in GROMACS
• Assessing and tuning performance of GROMACS simulations

The training includes two online sessions and participants are expected to attend both of them:

• Wednesday 24th January 2024 from 9:30 to 14:30 CET
• Thursday 25th January 2024 from 9:30 to 14:30 CET

Each session consists of lectures and hands-on exercises. GROMACS will be used in the exercise sessions. LUMI supercomputer will be used for the hands-on exercises. You need to apply for a user account, but we’ll provide the project and resources.
