// TODO: Create a tutorial on how to debug parallel programs using OpenMP in Visual Studio

// remember to add pictures if possible

// Steps

1. Read the Microsoft Documentation for your section

2. Paraphrase the contents of your section onto the Wiki

3. Test it yourself in Visual Studio and add examples

Process and Thread

Process

A process is an instance of a program executed by the computer. Processes are started when programs are initiated, and they can be comprised of one or more threads.

On Windows operating systems, you can look at your running processes on the Task Manager.

Thread

A single thread is a set of instructions that the CPU schedules and executes independently. A process consists of one or more threads which are able to be run concurrently. This forms the basis of multithreading.

Multiple Processes

// TODO: Explain why and how to run multiple processes in one or more projects in VS (long)

// use this: https://learn.microsoft.com/en-us/visualstudio/debugger/debug-multiple-processes?view=vs-2022

User Interface

// TODO: Show the window and explain what it does for every single window below (medium)

// documentation for windows are here: https://learn.microsoft.com/en-us/visualstudio/debugger/debug-threads-and-processes?view=vs-2022

Attach to Process Dialog Box

Walkthrough

// TODO: Step-by-step walkthrough on how to debug program with the specific window

// use same program for both tests

// can probably just take something from course notes and modify it to fit our parameters

Case A: Using the Thread Window
