Advent of Code 2025

This year, I did each day in a different programming model targeting GPU execution!

Solutions

Day	Programming Model	Run Command
01	CuTe	uv run python day01.py
02	cupy	uv run python day02.py
03	warp	uv run python day03.py
04	cudf	uv run --with "cudf-cu13=25.10.*" python day04.py
05	cuda.cccl	uv run python day05.py
06	numba-cuda	uv run python day06.py
07	C++ Standard Parallelism	./build/day07 (after building)
08	CUDA with CCCL	./build/day08 (after building)
09	OpenMP	./build/day09 (after building)
10	CUDA	./build/day10 (after building)
11	C++ std::execution	./build/day11 (after building)
12	OpenACC	./build/day12 (after building)

I also did Day 04 in OpenACC and Day 12 in cudf.

Dependencies

• uv with Python >= 3.13 installed
• CUDA >= 13.0
• NVIDIA HPC SDK >= 2025.09
• NVIDIA GPU with driver supporting CUDA 13
• CMake >= 4.0

Building

Run/modify ./build_all.sh as you see fit:

./build_all.sh

Running

Assuming you have all prerequisites in place and you already compiled the C++ solutions, simply invoke:

./run_all.sh
