1. For CUDA 11:

   Download latest 8.5.0 RPM distro cudnn-local-repo-rhel8-8.5.0.96-1.0-1.x86_64.rpm Use rpm2cpio to extract RPM contents and copy resulting 3 RPMS into sources and google drive:

   libcudnn8-8.5.0.96-1.cuda11.7.x86_64.rpm libcudnn8-devel-8.5.0.96-1.cuda11.7.x86_64.rpm libcudnn8-samples-8.5.0.96-1.cuda11.7.x86_64.rpm

2. For CUDA 12

   Download 8.9.6 RPM distro cudnn-local-repo-rhel8-8.9.6.50-1.0-1.x86_64.rpm There are separate RPMS for cuda 12.x and cuda 11.x for the same cudnn version, use one for cuda 12.

ffmpeg

FFmpeg is the most popular multimedia transcoding software and is used extensively for video and audio transcoding. NVENC and NVDEC can be effectively used with FFmpeg to significantly speed up video decoding, encoding, and end-to-end transcoding. For detailed info see https://docs.nvidia.com/video-technologies/video-codec-sdk/12.0/ffmpeg-with-nvidia-gpu/index.html

For ffmpeg v 6.1:

• install ffnvcodec headers (see ffnvcodec.yamlnd corresponding module file)
• compile ffmpeg with ffncodec and cuda modules.

VErify once built:

module load ffmpeg/6.1
ffmpeg -hide_banner -encoders  | grep nvenc
ffmpeg -hide_banner -decoders | grep cuvid
