# pyvx2-sbhadade

[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)
[![Python 3.8+](https://img.shields.io/badge/python-3.8+-blue.svg)](https://www.python.org/downloads/)

A high-performance Python library for AVX2-accelerated array and matrix operations.

## Features

- 🚀 **AVX2-Optimized Operations**: Leverages Intel AVX2 SIMD instructions for maximum performance
- 📊 **Matrix Multiplication**: Fast matrix-matrix multiplication using FMA instructions
- ➕ **Vector Operations**: Element-wise addition, multiplication, and dot products
- 🔧 **Production Ready**: Comprehensive error handling and edge case coverage
- 🧪 **Well Tested**: Full test suite with performance benchmarks

## Performance

PyVX2 provides direct AVX2 implementations for educational purposes and scenarios where you need explicit SIMD control. 

**Note**: For production workloads, NumPy with MKL/OpenBLAS backends may be faster due to:
- Multi-threading
- Cache-blocking algorithms
- Additional CPU-specific optimizations

PyVX2 is ideal for:
- Learning SIMD programming
- Embedding in single-threaded contexts
- Custom algorithmic optimizations
- Understanding low-level performance

Benchmark results on modern x86_64 CPUs:

## Installation

### From PyPI
```bash
pip install pyVX2
```

### From Source
```bash
git clone https://github.com/yourusername/pyVX2.git
cd pyVX2
pip install .
```

## Requirements

- Python 3.8+
- NumPy 1.19.0+
- x86_64 CPU with AVX2 support
- C compiler (GCC, Clang, or MSVC)

## Quick Start

```python
import numpy as np
from pyVX2 import matmul_avx2, add_avx2, mul_avx2, dot_avx2

# Matrix multiplication
A = np.random.randn(1000, 500).astype(np.float32)
B = np.random.randn(500, 800).astype(np.float32)
C = matmul_avx2(A, B)

# Vector addition
a = np.random.randn(10000).astype(np.float32)
b = np.random.randn(10000).astype(np.float32)
c = add_avx2(a, b)

# Element-wise multiplication
d = mul_avx2(a, b)

# Dot product
result = dot_avx2(a, b)
```

## API Reference

### `matmul_avx2(A, B)`

**Returns:**
- 2D NumPy array (M, N) of float32

### `add_avx2(a, b)`
Element-wise vector addition.

**Parameters:**
- `a`, `b`: 1D NumPy arrays (N,) of float32

**Returns:**
- 1D NumPy array (N,) of float32

### `mul_avx2(a, b)`
Element-wise vector multiplication.

**Parameters:**
- `a`, `b`: 1D NumPy arrays (N,) of float32

**Returns:**
- 1D NumPy array (N,) of float32

### `dot_avx2(a, b)`
Vector dot product.

**Parameters:**
- `a`, `b`: 1D NumPy arrays (N,) of float32

**Returns:**
- float: The dot product

## Benchmarks
