</PRE><PRE>The output file is as following:
Program PWSCF v.4.0.1 starts ...</PRE><PRE> Today is 24Sep2009 at 8:49:30
Parallel version (MPI)
Number of processors in use: 8
R & G space division: proc/pool = 8

I want to know whether it is necessary to set environment variable OPEN_MP_THREADS (I installed MPICH2 not OPENMPI) ?</PRE><PRE>Thanks very much for your help !</PRE><PRE>Best regards</PRE><PRE> </PRE><PRE> </PRE><br><br><span title="neteasefooter"/><hr/>
