cuSZ is a CUDA implementation of the world-widely used SZ lossy compressor. It is the first error-bounded lossy compressor on GPUs for scientific data, which significantly improves SZ's throughput in GPU-based heterogeneous HPC systems.
kSZ is a Kokkos-based implementation of the world-widely used SZ lossy compressor. We use Kokkos because it provides abstractions for both parallel execution of code and data management, which can be used to support portable implementation across different accelerator technologies. Kokkos can support OpenMP/OpenMPTarget, oneAPI, Pthreads, and CUDA as backend programming models.
