%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
optimized 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.
