Ubuntu with OpenMPI and OpenMP

This project provides scripts and tutorial to install OpenMPI and OpenMP on a Ubuntu Linux.

• Ubuntu Linux 18.04 LTS Server Edition — Amzon AMI ami-0f65671a86f061fcd
• SSH Key

• 1 MASTER Node, here you have to generate the ssh-key and update the script.
• N SLAVEs, here you have to run the script using the keys generated on the master node.

1. Copy on the MASTER node, from your local machine, the pem key: scp -i «k.pem» k.pem ubuntu@ec2-34-239-142-46.compute-1.amazonaws.com:
2. Login on the master node: ssh -i «k.pem» ubuntu@ec2-34-239-142-46.compute-1.amazonaws.com
3. Clone the repository: git clone https://github.com/spagnuolocarmine/ubuntu-openmpi-openmp.git
4. Generates the installing script for yourt cluster: source generateInstall.sh , results in a install.sh script with new ssh-keys for the cluster.
5. Run the script install.sh on the MASTER from the ubuntu user.
6. For each SLAVE instance run the install script from the MASTER node (ubuntu user): ssh -i

The passowrd for the pcpc user is root

1. On the MASTER node login in pcpc sudo login pcpc , password: root
2. Local login ssh localhost
3. Remote login on a slave node ssh IP

The program will create a new user pcpc and exchanges the given ssh keys.

• user: pcpc
• vim
• htop
• OpenMPI 4.0
• OpenMP included in the GNU GCC (last version)

Test the environment

You can test your local environment using the program test.c.

1. Compile the program: mpicc hello-mpi.c -o hello
2. Run the porgram: mpirun -np 2 ./hello
3. Run with more MPI processes on single core mpirun -np 3 —oversubscribe a.out

You can run directly on an homogeneous cluster machine that has been built using the same install script. You can run: mpirun -np 2 —hostfile hfile ./hello .

An example host-file is:
