CHAPTER 5: A Deeper Dive into CUDA

Here we explore some more details of CUDA programming, building on the Vector Addition example from the previous chapter.

• 5.1 Vector Addition Example: exploring CUDA by timing and experimenting
• 5.2 Vector Addition Example: see hardware in action
  • Parts that remain the same from the previous chapter
  • Differences for this example
  • The complete code for CPU to GPU comparison
  • Build and run on your machine
• 5.3 Exploring the effect of block and grid size settings
  • Case 3: Using a single block of threads
  • Case 4: Using a small fixed number of multiple blocks of threads
  • Case 5: Variable grid size method
• 5.4 Vector Addition Example: exploring thread block mappings
  • An Exercise
  • Build and run on your machine
  • Test your understanding
  • Summary
  • Exercises for Further Exploration
