CUDA by Example: An Introduction to General-Purpose GPU Programming

Chapter 12 The Final Countdown

Congratulations! We hope you’ve enjoyed learning about CUDA C and experimenting some with GPU computing. It’s been a long trip, so let’s take a moment to review where we started and how much ground we’ve covered. Starting with a background in C or C++ programming, we’ve learned how to use the CUDA runtime’s angle bracket syntax to easily launch multiple copies of kernels across any number of multiprocessors. We expanded these concepts to use collections of threads and blocks, operating on arbitrarily large inputs. These more complex launches exploited interthread communication using the GPU’s special, on-chip shared memory, and they employed dedicated synchronization primitives to ensure correct operation in an ...
