Hi
I was comparing the speed of QE build with --enable-openmp and --disable-openmp MPI was disabled ... >From what I see OpenMP is activated but the speed gain is zero ... I was searching for OpenMP optimization flags in QE fortran code like !$OMP PARALLEL etc ... But I did not find any in important source codes ... Did I not catch something or is there really no OpenMP optimization in QE and eventual MP speed up can be obtained only by the use of external (linear algebra, fft) libraries ?
