%description
The rocRAND project provides functions that generate pseudo-random and
quasi-random numbers.

The rocRAND library is implemented in the HIP programming language and
optimised for AMD's latest discrete GPUs. It is designed to run on top of AMD's
Radeon Open Compute ROCm runtime, but it also works on CUDA enabled GPUs.

%description -n hiprand
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.
