Dear All, As I mentioned in my previous e-mail that my QE is very slow when I run it in parallel. I have no problem on the same machine if I use some other code, e.g., SIESTA. I probably missing something in my compilation of QE. Please, have a look into the attached sys.make file that I used to compile QE. Also, if some one can share the parallel sys.make file. After the compilation, I just use mpirun -np 32 --hostfile machines ./mpi_script.sh where mpi_script.sh file just contain the command for pw.x (./pw.x < myfile.scf.in >OUT) Thanks, Gul
