LLaMeSIMD is the world's first benchmarking suite designed to evaluate how well large language models (LLMs) can translate between different SIMD (Single Instruction Multiple Data) instruction sets across various CPU architectures.
Think of it as Rosetta Stone Validator for SIMD intrinsics, powered by AI!
-
Multi-Architecture Support:
SSE4.2 (x86), NEON (ARM), VSX (PowerPC) -
Dual Test Modes:
- 1-to-1 Intrinsic Translation: "What's the NEON equivalent of
_mm_add_ps?" - Full Function Translation: Convert complete SIMD functions between architectures
- 1-to-1 Intrinsic Translation: "What's the NEON equivalent of
-
Multi-Model Evaluation:
Test local (Ollama), open (HuggingFace), and proprietary (OpenAI/Claude/DeepSeek) models -
Scientific Metrics:
- Levenshtein similarity
- AST structural similarity
- Token overlap analysis
-
Beautiful Visualizations:
Automatic generation of comparison charts and CSV reports
# Clone the repository
git clone https://github.com/VectorCamp/LLaMeSIMD.git
cd LLaMeSIMD
# Create and activate virtual environment
python -m venv venv
source venv/bin/activate
# Install dependencies
pip install -r requirements.txt
# Set up environment variables & edit with your API keys and model preferences
# To specify your preferred models, please list them as using commas
cd LLaMeSIMD
cp .env.example .env# Default architectures
python run_suite.py --engines SSE4.2 NEON
# Or select specific architectures (minimum 2 required)
python run_suite.py --engines NEON VSXAfter running the tests, review and clean the generated results stored in the Suite-Results directory. This step ensures accuracy by removing any artifacts or irrelevant outputs before proceeding to evaluation.
python evaluate_results.pyAfter evaluation, you'll get:
- Interactive Plots:
- Weighted score comparisons across models
- Architecture-specific performance breakdowns
- CSV Reports:
- Detailed metrics for each test case
SIMD optimization is crucial for:
- High-performance computing
- Game development
- Scientific simulations
- Computer vision
- Cryptography
LLaMeSIMD helps:
- Researchers benchmark model capabilities
- Dataset: Carefully curated intrinsic and function pairs (with significant help from our previously created tool, simd.info)
- Metrics:
- Levenshtein Similarity: Character-level accuracy
- AST Similarity: Structural correctness
- Token Overlap: Semantic similarity
- Weighted Scoring: 50% Levenshtein + 30% AST + 20% Token
- Add AVX-2 support
- Add AVX-512 support
- Add P@SS-1 Compilation Metric
