This book does not just shove the code on your face. It explains "how" things work under the hood. I loved this style so much that I made this book and its Volume 2 the textbook for my ECE655 Advanced GPU Programming and Deep Learning class. This book really spoke to me, since I am, just like the author Dan Godoy, are curious people who are not going to be satisfied when they get things to work. We want to know WHY they worked ! We want to know what is under the hood. This style of the author made it a perfect textbook material for a graduate class! The code he provided is a gold mine.
