giannozz 18658b544f Cleanup: zv moved to module "basis"

sbraccia 8d870d4cea The exit_file is no longer a parameter (set in io_files.f90 to "EXIT"), but an internal variable
set in input.f90 to "prefix.EXIT".
This is necessary to allow the user to stop the "correct" job when several jobs are
running on the same working directory.
C.S.

sbraccia 2a99b6fdac 1) An experimental parallelization of NEB images has been implemented.
This required a deep modification of the parallelism in PWscf:
there are two new communicators (intra_image_comm and inter_image_comm) and the
existing "pool" communicators (intra_pool_comm and inter_pool_comm) are now vectors
of length given by the number of parallel images. #ifdef __PARA is no longer
needed because all "parallel" variables are always initialized for a serial run
and all parallel routines are, in the case of a serial run, dummy routines.
The wrappers to MPI routines used only by PWscf are in the PW/para.f90 file.
The others (mp_***) are in the Modules/mp.f90. All explicit referencies to mpif.h
should be replaced by an "USE parallel_include" (in a serial run parallel_include
is simply a dummy module).

2) The extrapolation of both potential and wavefunctions has been rewritten in
order to be smarter than before: on the basis of the required extrapolation
order, on the basis of the history and on the basis of which files are really
present on the disk, the algorithm chooses the extrapolation order.
All the algorithms in which ions are moved can use the extrapolation.

These are both unstable features: I need the help of everybody to test them.

sbraccia 83abad3ff7 Call to the flush subroutine back to its place: too many "nonlocal effects" in using cpflush().

sbraccia 2efd90d37f General cleanup. The threshold for diagonalization (ethr) is now fixed to 1.D-5 at the first scf iteration (iter=1). A check is then performed to verify that the resulting density is adeguate (dr2/nelec > ethr). If it is not the diagonalization goes on with a smaller ethr. For iter > 1 ethr is updated with the old recipe. Also added a warning in update_pot that indicates "problems" in the wfc extrapolation. This problem has not yet been fixed.

degironc 63c59eb8b1 08 apr 2003 g_psi, g_psi_mod: new preconditioning (better behaved when
hdiag-e*sdiag is close to zero) used in cegterg. This
             removes most of the warning messages when using Davidson
             diagonalization. Although the overall performance (number of
             h_psi performed) does not seem to change very much in small
             tests, except pathological cases like ni.band.in in example1,
             it should be wise to have a more stable preconditioning.
             cegterg: use always GEMM instead of GEMV in the update.
             electrons: in a relaxation run perform accurately the first
             iteration after ionic move but reset the diagonalization
             threshold according to the actual self-consistence for the
             following ones.

cegterg, regterg: use GEMM instead of GEMV, do not require

dimensioned (nbnd,nkstot)) - misc. cleanup

Il calcolo di (H-eS)*psi ('update') nella diagonalizzazione iterativa
prendeva un tempo esagerato. L'ho modificata in modo da usare prodotti
matrice-matrice su tutti gli psi invece che matrice-vettore su ogni
psi, se piu' di 1/4 dei vettori non e' a convergenza. La cosa e' fatta
a naso e richiede ulteriori di prove, ma mi sembra che apporti dei
miglioramenti.

In TODO ho messo una lista di cose da fare.
