Running and Verifying MiniFE

Procedure

1. Use PuTTY to log in to the server as the root user.
2. Run the following command to run miniFE.x to generate a YAML file:

   mpirun --allow-run-as-root -n 96 ./miniFE.x nx=300 verify_solution=1

   

   nx indicates the size of each problem dimension.

   Check the values of Total CG Mflops: 34377.9 and Total Program Time: 29.567 in the generated YAML file.
