Issue for install Freefem on aws ubuntu 20.04

Hello I install Freefem on AWS with ubuntu 20.04, however when I test it with freefem to cout all the mpirank. they all print as 0, " ‘/usr/bin/mpiexec’ -np 4 /home/ubuntu/bin/FreeFem+±mpi -nw ‘TEST.edp’ -ne -v 0

hello I am mpirank 0

hello I am mpirank 0

hello I am mpirank hello I am mpirank 0

0" . I test the mpicc and mpirun with sample codes which it is okay. I was wondering if you guys have any experience with it thank you.

You are using two different MPI implementations.
