[QE-users] How to detect that QE is running in parallel

Hello Willem,
if it says "Serial version" it means that it was compiled without mpi support. If you run it with mpirun, you'll just get 4 copies of the code doing the same thing (and possible stepping on each other feet).

Please go back to the ./configure step and verify that the parallel environment was detected correctly (it says it at the end)
cheers
