(February 4, 2022)

Q-Chem is shipped as a single executable along with several scripts. No compilation is required. Once the package is installed it is ready to run. Please refer to the installation notes for your particular platform, which are distributed with the software. The system software required to run Q-Chem on your platform is minimal, and includes:

  • A suitable operating system.

  • Run-time libraries (usually provided with your operating system).

  • Vendor implementation of MPI or MPICH libraries (for the MPI-based parallel version only).

Please check the Q-Chem web site (www.q-chem.com), or contact Q-Chem support (support@q-chem.com) if further details are required.
