Academic licenses does not work with Ansys HPC licenses. The HPC license is only available for commercial/enterprise licenses.

Based on your current entitlement/licenses, you should be able to run a single simulation up to 1280 processes/cores. The simulation/project and the machine running the simulation will affect the performance. You can increase the number of processes/cores used to the run the simulation up to a point that increasing the number of processes/cores will not improve the performance.
