 ## Description
-This repository hosts the experiments and results for the Hybrid (MPI/pthreads) approach for the SOG construction and provides a short guide on how to install the tools and reproduce the results.
 
-  ** MPI : The Message Passing Interface ([OpenMPI](https://www.open-mpi.org/) implementation). The goal of the MPI is to establish a portable, efficient, and flexible standard for message passing between processess (nodes).
