Thrust + CUDA kernel

* --- Using Thrust vectors in kernel functions ---
* This example demonstrates how we can use device vectors (vectors that live
* in GPU) as arguments to a kernel launched by the CPU.

A stupid C++ trick for defining structs with metadata (serializers, printers, etc) without redundant declarations of members
View gist:d1e79721a898f721bcd279d107663c8b
#include <iostream>
#include <vector>
#include <string>
using std::string;
These macros define a struct with an implicitly defined Show function that visits each member.
The trick is that a typedef is split between each STRUCT_MEMBER instance and the preceding macro,
which allows it to define an empty struct type that identifies the following struct member, while also
knowing the struct type that the preceding macro is using to identify the current member.

Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

###Array ####Definition:

  • Stores data elements based on an sequential, most commonly 0 based, index.
  • Based on tuples from set theory.
