Parallel-Computing-Code

It is a repository for the Parallel Computing course at PVAMU.

Prerequisites

You need Linux or Mac OS to build and run these examples.

Linux Setup

You need to install the following software on Linux (recommend Ubuntu)

• GNU compiler (gcc and g++)
• git
• make

sudo apt install g++
sudo apt install git
sudo apt install make

AWS Amazon Linux

if you are using AWS Amazon Linux or Centos/Redhat, please use the following commands to install these software

sudo yum install gcc
sudo yum install gcc-c++
sudo yum install git

Mac Setup

You need to install xcode and libomp

If you don't have homebrew installed, please install it first by using the following command:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

xcode-select --install
brew install libomp

Install IDE

• any editor (such as vim, nano, notepad++, Atom, Visual Studio Code)
  • for example, install Notepad++ following instructions from this link

Getting Started

Fellow the instructions to get these examples, build and run them.

Clone the repository

git clone https://github.com/lhuang-pvamu/Parallel-Computing-Code.git

Build your code

Go to each directory (such as labs/lab1), and the build the code using make.

cd Parallel-Computing-Code

If you are using Linux, skip this step. If you are using Mac, you need to replace the make.def file with make.mac. Simply copy make.mac to overrite make.def:

cp make.mac make.def

Buid the lab 1 programs:

cd labs/lab1
make

Run your code

You need to set up the number of threads before you run an OpenMP code.

export OMP_NUM_THREADS=4

You may either run both sequential code and OpenMP code together by:

make run 

or you may run them individually:

./EXECUTABLE_NAME
