warp-types 0.3.2

# Makefile — C++ host loading Rust-compiled PTX via CUDA Driver API
#
# This builds a C++ program that loads PTX at runtime and launches kernels.
# The PTX comes from building Rust kernels with warp-types.
#
# Prerequisites:
#   - CUDA Toolkit (nvcc, libcuda)
#   - Rust nightly with rust-src (for building the Rust kernel crate)
#
# Usage:
#   make                            # Build the C++ host program
#   make ptx                        # Build Rust kernels to PTX
#   make run                        # Build everything and run
#   make clean                      # Remove build artifacts
