License for QuantumATK Parallel Run¶
You don’t need any special license to take advantage of OpenMP threading on multicore computers. To run QuantumATK in parallel over MPI, on a cluster or a single machine, you need so-called slave licenses, in addition to the basic “master” license. Each master license allows one calculation to be executed at the time, and each slave license can add one more parallel MPI node to a calculation. For more information on running QuantumATK in parallel, see the Parallel Guide.
