CUDA C++ in Practice: A Complete Developer's Guide to GPU Architecture, Parallel Algorithms, and Real-World Performance Optimization($27.99Value)

Description

The GPU Revolution Is Here. Are You Ready to Lead It? Every large language model you interact with, every self-driving car that sees the road, every weather forecast that saves lives, every drug discovered through simulation — none of it happens without GPU programming. And at the heart of GPU programming is CUDA C++. The engineers who truly understand CUDA — who can look at a kernel and immediately know why it is slow, who can close the gap between 10% and 90% of theoretical hardware peak, who can build systems that scale from one GPU to a thousand — are among the most sought-after and highest-paid technical professionals in the world today. CUDA C++ in Practice is the book that makes you one of them. This Is Not a Surface-Level Survey Most GPU programming books teach you the syntax. This book teaches you the system — the hardware architecture, the memory hierarchy, the execution model, the profiling methodology, and the iterative optimization discipline that separates programmers who write GPU code from programmers who write fast GPU code. You will not just copy examples. You will understand every design decision behind them. When something goes wrong — and in GPU programming, it will — you will know exactly where to look and what to fix. What You Will Build A high-performance matrix multiplication kernel that evolves from naive (3% of hardware peak) to Tensor Core accelerated (87% of cuBLAS) through four measured, profiling-driven iterations - A real-time image processing pipeline that processes HD video at 74+ fps using CUDA streams, pinned memory, and kernel fusion - A neural network forward pass from scratch — Dense layers, ReLU, numerically stable Softmax — benchmarked directly against cuDNN - A GPU-accelerated physics simulation with 32,768 gravitational bodies running at 88 fps, complete with spatial hashing collision detection and real-time OpenGL visualisation What You Will Master GPU Architecture — How SMs, warp schedulers, Tensor Cores, and RT Cores actually work inside Ampere, Hopper, and Blackwell GPUs - Memory Optimization — Coalescing, shared memory tiling, constant and texture memory, Unified Memory, and pinned transfers — the techniques that deliver the largest single performance gains - Parallel Algorithms — Parallel reduction, prefix scan, histogram computation, GPU radix sort, work queues, and dynamic parallelism — the algorithmic vocabulary of every high-performance GPU application - The CUDA Ecosystem — cuBLAS, cuFFT, cuSPARSE, Thrust, NCCL, multi-GPU P2P, and MPI+CUDA for scaling to thousand-GPU clusters - Profiling Like a Professional — Nsight Systems and Nsight Compute workflows, the Roofline Model, and the profiling-driven development cycle that makes every optimization decision defensible with data - Interoperability — CUDA with OpenGL, OpenCV, Python (PyCUDA, CuPy, Numba), and modern C++17/20 patterns including RAII wrappers and templated kernels - Debugging & Error Handling — Compute Sanitizer, production-grade error handling patterns, testable CUDA architecture, and the common bug patterns that trap even experienced developers Why This Book Is Different Most CUDA resources either stay too shallow — teaching basic kernels without performance context — or dive into academic theory without connecting it to practical engineering decisions. CUDA C++ in Practice occupies the space in between: it goes deep enough to be genuinely useful in a professional context, but explains every concept in clear, accessible language with concrete code examples and real benchmark numbers at every step. The GPU computing era is not coming. It is here. This is the book that prepares you for it.
