Run the benchmark in the environment

Warning

This page is outside of the scope of this tutorial: you can skip it.

As done previously, we have to go through the nxc build and nxc start phases.

Once the environment deployed, we connect with nxc connect

We can now try to run the benchmark.

mpirun -np 4 MADbench2.x 640 8 1 8 8 1 1

Unfortunalety this will fail for several reasons:

  • we are running as root

  • there are not enough slots to start 4 processes

As we are setting up the environment for now, we can disable these warnings by adding some flags:

mpirun --allow-run-as-root --oversubscribe -np 4 MADbench2.x 640 8 1 8 8 1 1
