[Wien] Installation of parallel version of Wien2k-12.1 : Reg.

[Gavin Abo]

You probably should adjust the settings in siteconfig.

./siteconfig
In the menu for example, select P, n, n, 0 (may not work correctly; 
refer to my previous mailing list post), ssh, y, enter your f90 
compiler, and the -DFFTW3 can be changed in FPOPT

If want to change in the Makefile manually (likely overriden if you use 
siteconfig), open the Makefile in a text editor:

vi $WIENROOT/SRC_lapw0/Makefile

You should see -DFFTW3 in the FPOPT line.  There should also be fftw3 
options in RP_LIBS, if it has not been changed from the default settings.
