Modules/functionals.f90 and flib/functionals.f90 and lsda_functionals.f90
Duplicated routine dmxc.f90 removed. Atomic code does not depend any
longer on PH/.
git-svn-id: http://qeforge.qe-forge.org/svn/q-e/trunk/espresso@2551 c92efa57-630b-4861-b058-cf58834340f0
charges are computed in real space only in spheres around the atoms and
these patches are added to rho on the dense fft grid.
Affected routines: addusdens and newd.
Should scale linearly with system size, as opposed to the quadratic
scaling of the G-space implentation.
Experimental version:
- no forces nor stress yet.
- parallel version to be tested
- not to mention phonon and the other codes ...
DISCLAIMER
There are accuracy issues to be understood better, we may need properly
modifies pseudopotentials in order to avoid (or reduce) errors when
ecutrho is still insufficient to describe all Fourier components of the
augmentation charge.
In this case (that is nearly always) also the usal G-space has errors
(negative charges for molecules and surfaces, for instance) but they are
usually small and we are used to live with them.
Some experience is needed to understand the relevance of the error related
to R-space augmentation charges.
CP has R-space augmentation with small-boxes.
They also produce some different, usually small, errors.
I think (I may be wrong) this is the origin of the fact that sometime PWscf
and CP total energies are not exactly the same.

written and read. Added some consistency checks. Postprocessing programs
not yet working (at least not all of them).

- core charge, same module between CPV and FPMD
- Makefile: added dependency between "mods" and "libiotk"
- Makefile: fix for dependencies in PH and Gamma when __NEWPUNCH is defined

exchange stuff.
These features can be obtained by compiling with -DEXX added to DFLAGS
in make.sys

noncolinear and spin-orbit cases. pwnc.x is no more needed and the
directory PWNC and all its files will be removed.
Step one: added to PW the noncolinear routines that have not been
merged, changes on all the Makefiles.

- Few more functionals has been added to file more_functionals.f90
since in PW BLYP/LSDA were not implemented .
In the same file, temporary, are stored old CP90 subroutines
for testing purpose ( in CP functionals were vectorized!! ).
The small program PP/xctest.f90 can be used to make a comparative
test between new and old routines, in case someone suspect a problem
there.
- buon anno!

in particular (modenum.ne.0) stands for iswitch = -4 now: is it OK?
unused show_memory routine also removed
documentation updated

(to be tested). Makefile and ChangeLog cleanup
Per favore scrivete qualcosa nel ChangeLog quando fate qualcosa
e verificate che tutto compile quando aggiungete roba - PG

added example for phonon DOS; version number updated to 2.1 (PG)
Please start testing and debugging the next version, i.e., this one.
Note that reference data have to be updated for all examples.

new module uspp_param, shared between PW and CP (in file Modules/uspp.f90)
The flag newpseudo is no longer used to decide whether states with oc=0 are
bound or not: for those states, and only for the old RRKJ format, oc is set
to a negative value, and this signals that they are not bound. Not elegant
but simpler than it used to be. The converter to UPF format did not include
those states anyway. Beware unexpected side effects!
