License for QuantumATK Parallel Run

You do not need any special license to take advantage of OpenMP threading on multicore computers. To run QuantumATK in parallel using MPI, on a cluster or a single machine, you need so-called DP licenses. The number of DP licenses determines how many MPI processes can be used for QuantumATK parallelization. For more information on running QuantumATK in parallel, see the Parallel Guide.
