Chapter 8, The CUDA Device Function Libraries and Thrust

1. Try it. (It's actually more accurate than you'd think.)
2. One application: a Gaussian distribution can be used to add white noise to samples to augment a dataset in machine learning.
3. No, since they are from different seeds, these lists may have a strong correlation if we concatenate them together. We should use subsequences of the same seed if we plan to concatenate them together.
4. Try it.
5. Hint: remember that matrix multiplication can be thought of as a series of matrix-vector multiplications, while matrix-vector multiplication can be thought of as a series of dot products.
6. Operator() is used to define the actual function.
