LULESH GPU Optimization

This repository contains multiple LULESH variants and experiments focused on GPU acceleration, including CUDA, OpenACC, and OpenMP versions, along with benchmarking scripts and results summaries.

Contents

• lulesh-cuda/: CUDA implementation and build files
• LULESH-openacc/: OpenACC implementation
• LULESH-codex-optimization/, LULESH-codex-translation/, LULESH-codex-translation-again/: Codex-assisted variants and logs
• LULESH-intel-translation/: Intel migration tool and translated variants
• HeCBench-lulesh-omp/: HeCBench OpenMP variant

Quick Start

Build in a specific subdirectory (example):

cd lulesh-cuda
make

Run the binary with an example problem size:

./lulesh -i 100 -s 200

Scripts

Run every implementation in this repo (each subdirectory's build/run flow) via:

./run_all.sh

Profile data transfers and runtime behavior with Nsight Systems:

./run_nsys_transfers.sh
