• MPI + OpenMP
• CUDA

More detailed information can be found in this blogpost.

Setup

Packages neede are, openmpi-bin for MPI and nvidia-cuda-toolit for CUDA

sudo apt install openmpi-bin
sudo apt install nvidia-cuda-toolkit

Usage

The parallel.sh file compiles each example and runs it for different number of threads and/or processes.

./parallel.sh
