[Pw_forum] GW code with Ultra-soft pseudo potential

[marsamos at democritos.it]

Dear user, at the moment there is no GW code with ultrasoft pseudo. I 
think that VASP (not GPL, nor interfaced with espresso) does have PAW 
(but maybe only in the development version). Anyway One of my 
collaborators try the GW in VASP and told me that it was very slow. boh!

There is in july a CECAM tutorial for GWW, maybe you can try to apply.
