Chapter 10
Concurrency Abstractions
Abstract
This chapter introduces a number of concurrency abstraction layers that provide the software developer some necessary abstractions for developing multicore software. Each of these abstraction layers has a technique for developing software using the approach, so several code examples are given for each approach. Pros and cons are discussed for each approach.

Writing code for multicore can be tedious and time-consuming. Here is an example. Below is the sequential code for a simple Dot Product:
#define SIZE 1000
Main() {
double a[SIZE], b[SIZE];
// Compute a and b
double sum = 0.0;
for(int i=0, i < SIZE; ...
