Dear PWscf users,
Do you have experience with running paraller version of the pw.x on P4 
HT processor?
My machines file contains  e.g.  the following line:

    my_host :2



but after running parraler pw.x :

    mpirun -np 2 pw.x -npool 2 < input_file

CPU time is nearly equal to the CPU time for sequensial version of pw.x.
Do you have any comments?

Best regards
Dariusz Chrobak
