Hello d3rioe,

I think in the user manual page 38, “2.11 Lesson 11: Run Your Programs on a Parallel Machine” has your answer.
“To run the program in parallel, use the command mpirun -np 2 ./cavity2d. Here -np 2 specifies the number of processors to be used”
Use the flag --use-hwthread-cpus to enable threads in addition to individual cores.
