%description
hipRAND is a RAND marshalling library, with multiple supported backends. It
sits between the application and the backend RAND library, marshalling inputs
into the backend and results back to the application. hipRAND exports an
interface that does not require the client to change, regardless of the chosen
backend. Currently, hipRAND supports either rocRAND or cuRAND.
