We are pleased to announce the publication of a setup guide for building an OpenMP + MPI environment on Ubuntu virtual machines running on mdx II (OpenStack).

This guide provides a clear, step-by-step explanation—complete with command examples—on how to build and run parallel programs in C using OpenMP × OpenMPI and OpenMP × Intel MPI.

Please note that processing performance may vary dynamically depending on the utilization of physical CPUs. Keep this in mind when using the environment for performance benchmarking and similar purposes.
