Warning!

Puhti and Mahti will be decommissioned after Roihu becomes available. Users should clean up unnecessary files and move any required data by the end of August 2026. See the Roihu data preparation instructions for details.

Puhti scratch is very full: keep only active data there and move or delete everything else. No new Puhti scratch quota will be granted.

PLUMED

PLUMED (PLUgin for MolEcular Dynamics) is an open-source, community-developed library that provides a wide range of different methods for enhanced sampling in molecular dynamics. It can be used with several MD codes.

Available

  • Puhti: 2.7.4, 2.8.0
  • Mahti: 2.6.3, 2.7.2
  • LUMI: 2.9.4, 2.10.0

License

The PLUMED license (L-GPL) also allows it to be interfaced with proprietary software.

Usage

The standalone module of PLUMED is for building your own applications and linking with PLUMED, or analysing results performed with such code. To use, first give module spider to locate all versions and their library dependencies:

module spider plumed
module load <dependencies reported by the spider command> plumed/<version>

To access CSC's PLUMED modules on LUMI, remember to first run:

module use /appl/local/csc/modulefiles

If you want to run molecular dynamics with PLUMED, either compile your MD engine of choice with PLUMED (see selection e.g. here), or use e.g. GROMACS, which is available at CSC. GROMACS versions >=2025.0 include PLUMED by default.
