What's Changed

This release includes a new CMake build process, new and improved autotuning configuration options, and compilation fixes for newer NVHPC releases with CUTENSOR 2.0. This release also includes initial opt-in support for NCCL User Buffer registration.

Breaking changes

  • #21 changed the attributetranspose_use_inplace_buffers in cudecompGridDescAutotuneOptions_t to an array of boolean values from a single value. This will require updates to C++ code using this autotuning option.
