Vertex-wise triangle counting

This project is implemented as a part of a homework exercise for [050] - Parallel & Distributed Systems course of ECE Department, AUTh.

This has implementations written in C and C++ for detecting and counting triangles in K3 graphs.

Getting Started

Prerequisites

1. CMake
2. Make
3. g++
4. OpenCilk
5. Python (3.6 or higher)

To install them on variant Linux distributions follow the instructions below

Fedora

$ sudo dnf upgrade --refresh # updates installed packages and repositories metadata
$ sudo dnf install cmake make gcc-c++ python 
# downloads the OpenCilk tarball from Github and moves it to /usr/local/ 
$ wget https://github.com/OpenCilk/opencilk-project/releases/download/opencilk%2Fbeta3/OpenCilk-9.0.1-Linux.tar.gz && \
 tar xvzf OpenCilk-9.0.1-Linux.tar.gz && mv OpenCilk-9.0.1-Linux/ /usr/local/ && chmod og+xr /usr/local/OpenCilk-9.0.1-Linux/

Ubuntu

$ sudo apt-get update && sudo apt-get upgrade # updates installed packages and repositories metadata
$ sudo apt-get install cmake make g++ python3 # ubuntu still offers python2 in its repositories
# downloads the OpenCilk tarball from Github and moves it to /usr/local/ 
$ wget https://github.com/OpenCilk/opencilk-project/releases/download/opencilk%2Fbeta3/OpenCilk-9.0.1-Linux.tar.gz && \
 tar xvzf OpenCilk-9.0.1-Linux.tar.gz && mv OpenCilk-9.0.1-Linux/ /usr/local/ && chmod og+xr /usr/local/OpenCilk-9.0.1-Linux/

Instructions

1. Clone the repository

   $ git clone git@github.com:pkarakal/vertexwise-triangle-counting.git

2. Go to that directory

   $ cd vertexwise-triangle-counting/

3. a. Generate Makefiles from the CMakefiles.txt

   $ cmake -S .

   b. There are additional cmake files that import OpenCilk and change the compiler to use the OpenCilk clang compiler and there is also the option to include ClangTidy support. By default, all the options are disabled. To enable the build of the executable that leverages OpenCilk run

   $ cmake -S . -DENABLE_OPENCILK=ON

   To enable the build of the executable that leverages OpenMP run

   $ cmake -S . -DENABLE_OPENMP=ON
   

   To enable the build of the executable that leverages PThreads run

   $ cmake -S . -DENABLE_PTHREADS=ON

   To enable Clang Tidy support use the following flag

   $ cmake -S . -DENABLE_CLANGTIDY=ON

4. Build and run the application

   $ cmake --build . && ./triangle_v{version}_{variant}

   where valid variants are cilk, openmp, serial, pthreads, and valid versions are 3 and 4. By default, only the serial is built
5. To run the formula validation first install numpy using

   $ pip3 install numpy

   or install it from the requirements.txt file running

   $ pip3 install -r requirements.txt

   and run the python script by executing the following command

   $ python3 ./formula-validation/validate.py
