nest

A fast, readable C++20 hydro library with CPU (OpenMP) and CUDA backends.

What It Does

• GPU/CPU hydro kernels with a backend-agnostic numerics layer
• SoA memory layout to drive vectorization and GPU coalescing
• Patch + halo decomposition for domain splitting and exchange
• Pipeline execution (Exchange → Compute → Reduce stages)
• Example solvers for 1D/2D Euler and linear advection
• Python visualization tools for plotting result files
