Parallel implementation of KNN algorithm, using C++ standard library and FastFlow.

To build and run the project I created a Makefile. First, you have to download the Fastflow library inside your working directory and then build the project by using the commands

git clone https://github.com/fastflow/fastflow.git
make

To test a specific version executable

./executable inputfile k nworkers

To compute the timings needed for the execution of a specific version there is the script average_time.sh, that iterates the execution a specified number of times, printing the timings needed for the Knn computation (Workers + Writer) and their average. Use the command

./average_time.sh executable inputfile k nworkers niterations
