DM-HEOM comprises a software suite to compute Open Quantum System Dynamics with the Hierarchical Equations of Motion approach [1]. DM-HEOM was developed by Matthias Noack based on physical models and prototypes provided by Tobias Kramer, Yaroslav Zelinskyi, and Mirta Rodríguez. Implementation details are described in [2] (computational part) and in [3] (equations used, physical reference spectra). Please see the Wiki for the documentation and examples. Acknowledgements DM-HEOM has been developed at the Zuse Institute Berlin (ZIB), Germany, in the framework of: the DFG Grant "Realistische Simulationen photoaktiver Systeme auf Hochleistungsrechnern mit Vielkernprozessoren" (Realistic Simulations of Photoactive Systems on HPC-systems with Many-Core Processors), (PIs: Dr. Tobias Kramer, Prof. Dr. Alexander Reinefeld), and the Intel Parallel Computing Center (IPCC) "Research Center for Many-core High-Performance Computing" at ZIB (PI: Dr. Thomas Steinke). We thank the North-German Supercomputing Alliance (HLRN) for providing computational resources. We further thank L. Deecke, J. Launer, L. Gaedke-Merzhäuser, and D.
