CUDA Memory Coalescing Explained: Access Pattern Optimization for GPUs | Uplatz

CUDA (Compute Unified Device Architecture) allows developers to unlock massive parallel performance on NVIDIA GPUs—but memory access patterns often determine whether your kernel runs fast or painfully slow. One of the most important performance concepts in CUDA programming is memory coalescing. In this video, we break down how memory coalescing works and how to optimize access patterns for maximum throughput. This Uplatz Explainer video starts with the fundamentals of GPU memory hierarchy and global memory behavior. We explain how threads within a warp access memory, how memory transactions are formed, and why scattered accesses dramatically reduce bandwidth efficiency. We then dive into what memory coalescing actually means. Topics include warp-level memory transactions, contiguous memory access, alignment requirements, stride-based access, and how the hardware groups memory requests. You’ll understand why properly aligned and sequential access patterns are critical for performance. The video also explores optimization techniques for improving coalescing. We cover restructuring data layouts (AoS vs SoA), adjusting thread indexing strategies, eliminating misaligned accesses, minimizing strided patterns, and using shared memory to reorganize data. You’ll see how minor indexing changes can unlock major performance gains. Finally, we connect memory coalescing to real-world GPU workloads such as matrix operations, deep learning kernels, reductions, and large-scale data processing. By the end of this video, you’ll have a practical framework for designing CUDA kernels that maximize memory bandwidth utilization. This video is ideal for GPU programmers, ML engineers, HPC developers, and anyone optimizing CUDA-based parallel workloads. #CUDA #GPUProgramming #MemoryCoalescing #ParallelComputing #HPC #AIInfrastructure #PerformanceOptimization #DeepLearning #NVIDIA #Uplatz ---------------------------------------------- 🌐 Welcome to Uplatz – Your Gateway to Career Transformation!
