Online: Advanced GROMACS workshop

This course gives a practical introduction 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 and advanced sampling techniques are discussed. CSC’s Puhti and Mahti supercomputers 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 and CSC and supported by PRACE.

Learning outcome

After the course the participants should have the skills and knowledge needed to efficiently use CPU and GPU resources in GROMACS simulations.


The participants are assumed to have working knowledge of GROMACS, basic Python and Linux/Unix skills are required. The fundamentals of molecular dynamics or basic usage of GROMACS are not covered on this course. Please consult these materials, if you’re uncertain of your Python, Linux or GROMACS skills.
