This repository is a list of examples of the implementation of concurrent computing done in C using the POSIX Threads library, built during the discipline of Concurrent Computing at the Federal University of Rio de Janeiro and taught by Prof. Silvana Rossetto (DCC-- UFRJ)
It is recommended that you use a Linux, macOS or WSL system if you use windows to run and run programs
First notion of creating threads to create a hello world in multiple threads and present the concept of concurrent computing
Shows the use of threads to manipulate arrays, increasing the value of each position by 1
Program that performs the multiplication of a matrix by a vector, has a sequential version and versions with different concurrent solutions.
Program that performs the multiplication of a square matrix by a square matrix, has a sequential version and a concurrent version. In the folder you will also find a benchmark analysis on the advantages of a concurrent approach.
Program that traverses an array of double and adds their values
Program that use threads to calculate a aproximation to pi value
Program that use threads to calculate array prefix sum
First notion of creating threads in Java to create a hello world in multiple threads and present the concept of concurrent computing
Program that use threads to calculate increment a variable
Shows the use of threads in Java to manipulate arrays, increasing the value of each position by 1
Shows the semaphore example in threads

cd concurrent-computing-examplesYou can open powershell as wsl with the command:
wsl code .You can run each example by running its respective .exe file or build with the command:
gcc fileName -o exitName -Wall -lpthread
./exitName argsYou can compile and run with java with the following commands:
javac Main.java
