Release R2.13 · WolframRhodium/VapourSynth-BM3DCUDA

Added support for AMD GPUs via HIP. supported GPUs
- Output frames may be broken. (#23)
- The code is designed for discrete RDNA GPUs (with wavefront size 32 and a separate address space), and may not work on GCN and CDNA GPUs.
- Since current AMD's implementation of HIP does not provide support for backward compatible virtual ISA like PTX in CUDA, the bm3dhip binary will not be able to run on future AMD GPUs or GPUs that are not current compilation target. This could be modified here.
- Only bm3dhip is available at present. bm3dhip_rtc, the hiprtc-based counterpart to bm3dcuda_rtc have to wait at least until ROCm 6.1.0 because of the missing support for some features.
