[Q-e-developers] More on scalability of QE/CP on FERMI

[Stefano de Gironcoli]

ciao Carlo,
   great! it would be nice to have a similar graph for PW as well (and 
PH...?) and to unify the way the different parallelizations are made in 
the various codes so that one does not need to duplicate the effort ...
ciao,
   stefano
