[Debugging] Image Loading and CUDA Processing with Nsight Profiling and OpenCV
This post investigates and resolves a bug encountered while transferring 2D image data to device memory and processing it with CUDA kernels.

Image Loading and CUDA Image Processing with Nsight Profiling and OpenCV
This post explains how to use Nsight to profile CUDA performance, how to load images with OpenCV, and how to transfer 2D images to device memory for processing with CUDA kernels.
CUDA Memory Transfer Timing: malloc, managed, and zero-copy
I measured the transfer time of 2GB memory between CPU and GPU using cudaMalloc, cudaMallocManaged, and cudaHostAllocMapped (Zero-Copy).
Three CUDA Memory Allocation Methods and Zero-Copy Mapping
In this post, I explore and visualize three memory allocation strategies in CUDA: cudaMalloc, cudaMallocManaged, and cudaHostAlloc—with an additional test on zero-copy memory mapping.
