+In principle, running this benchmark on the HPC only requires RDKit and the Python packages listed in "singularity-install/requirements.txt". However, different HPC might have slightly different environments. We will show two examples of executing our benchmark in the University of Connecticut (UConn) HPC cluster and Extreme Science and Engineering Discovery Environment (XSEDE).
