So, the more cores a program can use simultaneously, the faster the program will run.
#GOSYNC MAP CODE#
These processors have one or more “cores,” each capable of running one stream of code at the same time. In a modern computer, the processor, or CPU, is designed to run as many streams of code as possible at the same time. Running Functions at the Same Time with Goroutines
#GOSYNC MAP HOW TO#
Familiarity with Go functions, which you can find in the How to Define and Call Functions in Go tutorial.
#GOSYNC MAP INSTALL#
To set this up, follow the How To Install Go tutorial for your operating system. Finally, you’ll add more goroutines to the program to simulate a program running with multiple worker goroutines. Then you will add channels to that program to communicate between the running goroutines. First, you will create a program that uses goroutines to run multiple functions at once. In this tutorial, you will explore both goroutines and channels. Goroutines solve the difficulty of setting up and running concurrent code in a program, and channels solve the difficulty of safely communicating between the code running concurrently. Two features in Go, goroutines and channels, make concurrency easier when used together. To run programs faster, a programmer needs to design their programs to run concurrently, so that each concurrent part of the program can be run independently of the others. Being able to run code concurrently is becoming a larger part of programming as computers move from running a single stream of code faster to running more streams of code simultaneously. One of the popular features of the Go language is its first-class support for concurrency, or the ability of a program to do multiple things at once.
