PANS is a parallel implementation of the Asymmetric Numeral Systems (ANS) compression algorithm. It supports asymmetric compression and decompression across different hardware architectures, enabling flexible deployment based on system requirements. Specifically, it allows:

• Parallel compression on NVIDIA/AMD GPUs using dietGPU, with parallel decompression on multi-core CPUs.
• Parallel compression on multi-core CPUs using PANS, with parallel decompression on NVIDIA GPUs via dietGPU.
