Dear forum,
   I'm trying to compare the speed of abinit versus some
other DFT code and I realized that other codes which uses
ultra-soft pseudo-potential are faster than abinit.

Anyway, from what I undestood, using PAW one should be
able to have performances like "DFT ultrasoft codes"
if the starting point for  the computation is a converted ultrasoft.

I tryed to use the PAW atomic data table from the abinit website:
http://www.abinit.org/PAW/MAIN/PAWTable.html
but unfortunately they are not suited for spin polarized calculations.

So two questions:
 - Can I use PAW for spin polarized calculations?
 - Using PAW are there particularly drawbacks with respect to the
    standard pseudo-potential methods?

Thanks. Best regards,
Davide
