This course gives advanced practical tips on how to run GROMACS MD simulations efficiently on modern hardware including both CPUs and GPUs. In addition to speeding up MD simulations, also workflow automation, advanced sampling techniques and future developments are discussed. CSC's Puhti supercomputer will be used for the hands-on exercises.

The course consists of lectures and hands-on exercises. GROMACS will be used in the exercise sessions.

The event is organized in collaboration with BioExcel, CSC, ENCCS and supported by EuroCC.

Learning outcome

After the course the participants should have the skills and knowledge needed to 1) efficiently use CPU and GPU resources in GROMACS simulations 2) apply workflows and python API for GROMAC simulations and 3) run QM/MM simulations.

Prerequisites

The participants are required to be familiar with MD, have working knowledge of GROMACS, and basics of BioBB, also basic Python and Linux/Unix skills are required. The fundamentals of MD or basic usage of GROMACS are not covered on this course. Please consult the following materials, if you're uncertain of your Python, Linux or GROMACS or BioBB skills:

• Lectures on the basis of molecular dynamics simulation (videolinks: part I, part II)

• MD with GROMACS tutorials (link)

• A basic Python introduction (link, available also via CSC Notebooks), in addition to the very basics, knowing functions, decorators and 'with' context manager will be useful.
  

• A short guide to Jupyter Notebook (pdf)

• Linux commands, bash shell, a quiz and a link to intro course (link)
• BioBB introductory videos (link), installation tutorials (link) and demonstration workflows (link)

Agenda (NOTE: times are CET)

There will be 10 minute breaks in the morning and afternoon sessions.
