MPI&OpenMP Integral Computer

• The Task itself

Outline

The main task of this project is to compute the integral

$$\int\limits_0^1\frac{4}{1+x^2}dx$$

on the a one node and then distribute the computation to the different nodes and measure an acceleration.

Report

Detailed report can be found in report.ipynb jupyter notebook.

Prerequisites

• OpenMPI distribution
• OpenMP
• CMake
• Access to the cluster running Slurm Workload Manager (optional)
• Ansible (optional)

Build

Do the following in the root repository folder:

mkdir build && cd build
cmake ..
make

Running

Run locally

mpiexec -n 4 ./bin/count-integral 1000000 1

Run on cluster

• Install ansible

pip3 install -r requirements.txt

• Change ansible/hosts file with your host and password

remote ansible_host=[e-mail] ansible_ssh_pass=PASS

• Run playbook
  • The playbook will prompt you to continue when slurm jobs are finished (you can check this on cluster by running squeue command)

ansible-playbook -i ansible/hosts ansible/run-bench.yml

• When playbook finished, data will appear in the result.csv file.
