GPUPy 0.1.1

GPU Accelerated Numerical Methods Library

GPUPy

GPUPy is a high-performance Python library for numerical methods, offering seamless support for both CPU and GPU computations. It is designed for students, researchers, and engineers who need efficient and scalable numerical tools for scientific computing.

✨ Features

• ✅ CPU (NumPy) and GPU (CuPy) support with automatic backend switching
• 🔁 Root Finding Methods (e.g. Bisection, Newton-Raphson)
• 🔬 Differentiation Techniques (Forward, Backward, Central Differences)
• ∫ Integration Methods (Trapezoidal, Analytical)
• 📈 Interpolation (Linear and Cubic Spline with GPU versions)
• 🔄 Linear System Solvers (Direct methods, LU Decomposition)
• 🧠 Optimization wrappers (using SciPy)
• 🧮 ODE Solvers (via scipy.integrate)
• ⏱ Benchmarking utilities for performance comparison
• 📊 Built-in plotting support for interpolations and function visuals

🔧 Installation

Usage Example

import GPUPy as gp

def f(x): return x**2 - 4
def df(x): return 2 * x

# CPU
root = gp.newton_raphson(f, df, x0=3, use_gpu=False)

# GPU
root_gpu = gp.newton_raphson(f, df, x0=3, use_gpu=True)

print("Root (CPU):", root)
print("Root (GPU):", root_gpu)

Benchmark Example

from GPUPy.src.numerical_methods.utils import benchmark
from GPUPy import bisection

def f(x): return x**2 - 4

cpu_time = benchmark(bisection, f, a=0, b=5, use_gpu=False)
gpu_time = benchmark(bisection, f, a=0, b=5, use_gpu=True)

print(f"CPU: {cpu_time:.6f}s | GPU: {gpu_time:.6f}s")
