The GPU workflow now patches pyproject.toml to set the distribution name to 'openimpala-cuda' before building. The import name stays 'openimpala' — only the pip package name differs, so users choose between `pip install openimpala` (CPU) and `pip install openimpala-cuda` (CUDA GPU). __init__.py resolves version from either package. All tutorials and notebooks updated to install openimpala-cuda to leverage Colab T4 GPUs. https://claude.ai/code/session_01WR9HkUD95rp3XzZU95j2y7

The manylinux_2_34 container ships GCC 14+ which is unsupported by CUDA 12.6's nvcc (max GCC 13). Install gcc-toolset-13 and set CC/CXX/FC to GCC 13 for all dependency builds and wheel compilation. Also fixes: - Quote semicolons in CMAKE_CUDA_ARCHITECTURES to prevent shell splitting (was causing "sh: line 1: 70: command not found" errors) - Pass CUDAFLAGS="-allow-unsupported-compiler" to HYPRE build as safety net - Set CUDAHOSTCXX and CMAKE_CUDA_HOST_COMPILER for AMReX and OpenImpala - Bump cache key to force rebuild with new toolchain https://claude.ai/code/session_01WR9HkUD95rp3XzZU95j2y7
