Glotzerlab software

glotzerlab-software deploys software developed by the Glotzer group at the University of Michigan to HPC resources via conda packages. Use glotzerlab-software to install an MPI and GPU enabled build of HOOMD-blue and related packages on a HPC resource.

Use the standard conda-forge provided HOOMD-blue (mamba install hoomd with no special configuration) for serial execution on individual workstations.

• Documentation: Tutorial, usage information, and list of supported HPC resources.
• glotzerlab-software discussion board: Ask the glotzerlab-software user community for help.
• HOOMD-blue: The general-purpose particle simulation toolkit that glotzerlab-software packages.

Quick start

1. Install miniforge.

2. Replace $HOME/miniforge3/.condarc with:

   channel_priority: strict channels:

   • file://path/to/conda/channel

   • conda-forge

     disallow:

     • openmpi
     • mpich
     • cuda-cudart-dev

3. Install HOOMD-blue:

   mamba install hoomd

4. Load prerequisite modules. For example:

   module load openmpi cuda

5. Execute Python scripts with MPI and GPU support. For example:

   srun -n 8 python3 script.py

You can confirm that the correct package was installed with mamba list hoomd. The full package build will contain the cluster name and a gpu or cpu suffix. For example:

# Name      Version   Build                          Channel
hoomd       X.Y.Z     cluster_gpu_py311h1b32822_0    file://path/to/conda/channel
