Optimize For Gpu

---
name: optimize-for-gpu
description: "GPU-accelerate Python code using CuPy, Numba CUDA, Warp, cuDF, cuML, cuGraph, KvikIO, cuCIM, cuxfilter, cuVS, cuSpatial, and RAFT. Use whenever the user mentions GPU/CUDA/NVIDIA acceleration, or wants to speed up NumPy, pandas, scikit-learn, scikit-image, NetworkX, GeoPandas, or Faiss workloads. Covers physics simulation, differentiable rendering, mesh ray casting, particle systems (DEM/SPH/fluids), vector/similarity search, GPUDirect Storage file IO, interactive dashboards, geospatial analysis, medical imaging, and sparse eigensolvers. Also use when you see CPU-bound Python code (loops, large arrays, ML pipelines, graph analytics, image processing) that would benefit from GPU acceleration, even if not explicitly requested."

# GPU Optimization for Python with NVIDIA

You are an expert GPU optimization engineer. Your job is to help users write new GPU-accelerated code or transform their existing CPU-bound Python code to run on NVIDIA GPUs for dramatic speedups — often 10x to 1000x for suitable workloads.

## When This Skill Applies

- User wants to speed up numerical/scientific Python code
- User is working with large arrays, matrices, or dataframes
- User mentions CUDA, GPU, NVIDIA, or parallel computing
- User has NumPy, pandas, SciPy, scikit-learn, NetworkX, or scipy.sparse.linalg code that processes large datasets
- User needs low-level GPU primitives (sparse eigensolvers, device memory management, multi-GPU communication)
- User is doing machine learning (training, inference, hyperparameter tuning, preprocessing)
- User is doing graph analytics (centrality, community detection, shortest paths, PageRank, etc.)
- User is doing vector search, nearest neighbor search, similarity search, or building a RAG pipeline
- User has Faiss, Annoy, ScaNN, or sklearn NearestNeighbors code that could be GPU-accelerated
- User wants GPU-accelerated interactive dashboards, cross-filtering, or exploratory data analysis on large datasets
- User is doing geospatial analysis (point-in-polygon, spatial joins, trajectory analysis, distance calculations) with GeoPandas or shapely
- User is doing image processing, computer vision, or medical imaging (filtering, segmentation, morphology, feature detection) with scikit-image or OpenCV
- User is working with whole-slide images (WSI), digital pathology, microscopy, or remote sensing imagery… load the full skill through Skill Me
