Hands-On GPU Programming with Python and CUDA

Overview of this book

Hands-On GPU Programming with Python and CUDA hits the ground running: you’ll start by learning how to apply Amdahl’s Law, use a code profiler to identify bottlenecks in your Python code, and set up an appropriate GPU programming environment. You’ll then see how to “query” the GPU’s features and copy arrays of data to and from the GPU’s own memory. As you make your way through the book, you’ll launch code directly onto the GPU and write full blown GPU kernels and device functions in CUDA C. You’ll get to grips with profiling GPU code effectively and fully test and debug your code using Nsight IDE. Next, you’ll explore some of the more well-known NVIDIA libraries, such as cuFFT and cuBLAS. With a solid background in place, you will now apply your new-found knowledge to develop your very own GPU-based deep neural network from scratch. You’ll then explore advanced topics, such as warp shuffling, dynamic parallelism, and PTX assembly. In the final chapter, you’ll see some topics and applications related to GPU programming that you may wish to pursue, including AI, graphics, and blockchain. By the end of this book, you will be able to apply GPU programming to problems related to data science and high-performance computing.

Questions

  1. Try rewriting the Monte Carlo integration examples (in the __main__ function in monte_carlo_integrator.py) to use the CUDA instrinsic functions. How does the accuracy compare to before?
  2. We only used the uniform distribution in all of our cuRAND examples. Can you name one possible use or application of using the normal (Gaussian) random distribution in GPU programming?
  3. Suppose that we use two different seeds to generate a list of 100 pseudo-random numbers. Should we ever concatenate these into a list of 200 numbers?
  4. In the last example, try adding __host__ before __device__ in the definition of our operator() function in the multiply_functor struct. Now, see if you can directly implement a host-side dot-product function using this functor without any further modifications.
  5. Take a look at the strided_range.cu file in the Thrust examples directory. Can you think of how...
