calculation of VHXC is taken out of EnergyFunctional.
RunCmd modified. Use run niter nitscf nite.
Added FermiTemp variable.
Modifications for calculation of occupation numbers if nempty > 0.

Makefile modified for libqb.a target for BGL.
Known bug: SpeciesReader.C incorrect if not USE_XERCES
Known bug: Base64 encoding not done in SlaterDet.C
--------------------------------------------------------------------------------
rel1_17_1 2004-08-18
Fixed bug #27: overrun of variable tmpfion in NonLocalPotential.C is due to
incorrect index calculation in situations where na[is] % (ntasks/nrowmax) != 0.
This is the case for (CdSe)_110 on 128 tasks, nrowmax=32, since na[is]/4 = 27.5.
Note: bug #27 does not affect calculations with a single non-local projector
(npr[is]==1).
Fixed bug #33 LDAFunctional.C: incorrect use of Perdew-Zunger caused small
differences (~1.e-3 a.u.) in total energy when compared to other codes.
The adjustment of the constant gamma to make the PZ energy function continuous
was incorrect. Instead, the constants C and D must be adjusted to ensure
continuity of Ec and its derivative at rs=1.
--------------------------------------------------------------------------------
rel1_17_0 2004-08-11
Fixed buffer overrun in Context::string_bcast. (note: bug #27 is not fixed).
Fixed bug 26: inconsistent qbox xmlns namespace in species file and qbox output.
Modified qb.C: use new qbox_xmlns() function to print qbox XML namespace.
EnergyFunctional.C:909: change lda argument to 14. This was done automatically

--------------------------------------------------------------------------------
rel1_16_0
Implemented l=1,l=2 non-local stress.
Modified UnitCell.C to avoid infinite loops due to finite precision.
Modified mcr.mk to use library mkl_p4 instead of mkl: -lmkl_p4 before -lmkl
This change of library accelerates the si432 calculation by 12% overall
--------------------------------------------------------------------------------
rel1_15_2
Ecut.h: exit without any action if ecut is same as current value. Caused
zeroing of the wavefunction velocity when used in a redundant manner.
Added isodate.C/isodate.h and release.C/release.h files for separate access
to these functions from any other object.
Added a <description> tag in the sample file in SaveCmd.C including the ISO
date and the release of qbox that was used to create the file.
(Note: the tag was already allowed by the Schema specification, but the
save command did not write any description information.)
--------------------------------------------------------------------------------
rel1_15_1
Fixed bug: stop on assert in NonLocalPotential for l=1 or l=2 projectors
Fixed bug: Matrix::init_size() with zero dimensions.
Known bugs:
-wf_diag variable is ignored.
--------------------------------------------------------------------------------
rel1_15_0
Added R option for the cell_lock variable: rescale unit cell only (keep aspect
ratio fixed).
Corrected inconsistencies between BOSampleStepper.C and CPSampleStepper.C as
regards printing of variables during a run: unit_cell, enthalpy, pv.
Known bugs:
-Stops on assert in NonLocalPotential::update_twnl() for l=1 or l=2 projectors
-Crashes when defining a species without using it, i.e. species with zero atoms.
 Traced to incorrect initialization of sizes in Matrix.C
--------------------------------------------------------------------------------
rel1_14_3
Fixed calculation of ekin_e in MDWavefunctionStepper.C to avoid small error
when printing ekin_e at the first iteration of a CP run. Note: only the printed
ekin_e is affected, wfs are correct.
--------------------------------------------------------------------------------
rel1_14_2
Fixed Thermostat in MDIonicStepper.C
Fixed use of ionic velocities at first step in CPSampleStepper.C
Known bug:
Calculation of ekin_e in MDWavefunctionStepper.C at the first iteration uses
the wf velocity at t=0. This is second order accurate, but not consistent with
the calculation of ekin_e in subsequent steps, which introduces a small error
in the printed ekin_e at the first iteration. Ekin_e should be calculated using
a first-order expression, i.e. (wf0-wfm)/dt to be consistent.
--------------------------------------------------------------------------------
rel1_14_1a
SlaterDet.C: Removed messages from resize about cell being enclosed by ref_cell.
Note: the determination of enclosure should be revised.
SDCellStepper.C: removed debug messages. New "S" option to preserve shape.
BOSampleStepper.C: Added output of cell dimensions if cell is not locked.
Preconditioner.C: bug fixed in calculation of diag when using confinement.
Known bugs:
Does not use ionic velocities at first step of CP dynamics.
Thermostat is not working.
--------------------------------------------------------------------------------
rel1_14_0
Matrix.h Reintroduced the clear() call in the resize members. Working with
uninitialized matrices sometimes caused NaNs to appear in the padding areas
of the danl matrix in NonLocalPotential.C.
Note that the clear() call was removed in rel1_13_0, which invalidates 1_13_0.
Matrix.C: Added assert()'s in clear() functions.
BOSampleStepper.C: Introduced quadratic wf extrapolation option (switch
in BOSampleStepper.C, currently disabled in 1.14.0. Added calculation
of forces at each electronic step to monitor the convergence
of the force x velocity product (disabled in 1.14.0).
PSDWavefunctionStepper.C: Fixed bug in usage of preconditioner (affects
1_13_0 only).
PSDAWavefunctionStepper.C: Fixed bug in usage of preconditioner (see above).
SlaterDet.[Ch]: introduced new orthogonalization and alignment functions:lowdin,
align, ortho_align.


--------------------------------------------------------------------------------
rel1_13_0 (not for release, see Matrix clear() bug above)
Implemented stress calculation and variable cell dynamics
Stress calculation works for s-only non-local potentials.
Changed names of variables tau0, taup to r0, rp (and keep tau for scaled
coordinates)
modified the IonicStepper interface to separate the calculation of rp
from the update r0 := rp.
Removed a bug in calculation of eta at first step (was not using ekin_ion)
--------------------------------------------------------------------------------
rel1_13_0a1 (not for release)
Computes stress tensor. Limited to s-only n-l projectors. No cell eq. of
motion yet. Tested against GP results in cubic Si64.
--------------------------------------------------------------------------------
rel1_12_1
Removed Gauss-Jacobi quadrature in NonLocalPotential introduced in 1_12_0 and
reverted to trapezoidal rule. Tests on Si64 using trapezoidal, Simpson, Gauss-
Legendre and Gauss-Jacobi show that the trapezoidal rule is more efficient
than all other methods, likely because higher order methods are not in their
asymptotic range for reasonable numbers of points  (4-32). A possible
improvement over the present status may be to use Richardson extrapolation,
since the trapezoidal rule has O(h^2) error. However, from the example of Si64,
little improvement is obtained for small (4-8) numbers of points.
--------------------------------------------------------------------------------
rel1_12_0
Replaced trapezoidal integration in NonLocalPotential.C by a Gauss-Jacobi rule.
(Note: this was later found to be less efficient. Removed in 1.12.1e)
Fixed bug in PSDWavefunctionStepper.C and PSDAWavefunctionStepper.C:
use ecut if ecutprec==0.0. Caused nans when ecutprec was not set.
--------------------------------------------------------------------------------
rel1_11_2 2003-12-04
Fixed Elan allocation failure problem in SlaterDet::write. Problem was caused
by the large number of buffers allocated by the elan lib for all the messages
sent to task 0 before a receive was posted for them. A barrier in the loop
over states limits the number of messages sent to task 0 at any given time.
Note: the problem likely doesn't show on AIX since the MPI implementation may
limit the number of buffered received messages. The barrier is added in the
AIX code too (SlaterDet::print).
--------------------------------------------------------------------------------
rel1_11_1
Fixed uninitialized var eta_ in MDIonicStepper that caused errors on AIX.
Known problem: elan allocation failure on mcr when writing h2o64 sample
using 140 tasks on 70 nodes. Possible bug in SlaterDet::write if USE_CSTDIO_LFS.
When running on AIX (using SlaterDet::print instead of SlaterDet::write) no
problem arises, and memory usage per node is low.(fixed in 1_11_2).
--------------------------------------------------------------------------------
rel1_11_0
BOSampleStepper: changed to do extrapolation and ionic move before
smoothing the wf. Uses wf velocity if available. Creates it if not
Included PSDA wf stepper.
BO dyn Works ok with PSDA.
Tested 1pe vs 2pe on CH4 BO dynamics: ok.
Corrected bug in SampleReader.C (reading of wf velocity, appeared in rel1_9_0)
--------------------------------------------------------------------------------
rel1_10_0 (not for release) (Note: known bugs)
Complete rewrite of the SampleStepper hierarchy, including CP and BO classes.
Runs CP and BO/SD and BO/PSD tests ok. No extrapolation of wavefunctions yet.
Note: wavefunction extrapolation implemented yet.
Planned work: interchange nite iterations and ionic move in BO stepper, so
that the wfs at the end of the iteration are the GS for the ionic positions at
the same time.
XML files: a <description> tag (optional) was added to the sample.xsd file
to include any information about the sample that a user may want to include.
Bug in SampleReader.C: reading of density matrix for the
wavefunction velocity is incorrect. Causes out of sync MPI call and Abort
Corrected in 1_11_0 (candidate)
--------------------------------------------------------------------------------
rel1_9_0 (Note: known bugs)
Large file support (LFS): LFS is not correctly supported for <iostream> in icc
and gcc 3.2. A workaround is implemented in SaveCmd.C, Wavefunction.C,
SlaterDet.C. The workaround is activated by defining the USE_CSTDIO_LFS macro.
Occupation numbers moved to the SlaterDet class.
Occupation numbers are not fixed to 2.0 anymore. Load and save now use
occupation numbers.
Bug in SampleReader.C: reading of density matrix for the
wavefunction velocity is incorrect. Causes out of sync MPI call and Abort
Corrected in 1_11_0 (candidate)
--------------------------------------------------------------------------------
rel1_8_2
Fixed problem with wfvtmp in SampleReader: cannot load sample and
then set wf_dyn = MD. Also, the order of load and set wf_dyn MD commands causes
a seg fault.
--------------------------------------------------------------------------------
rel1_8_1
Fixed large-file support for sample files.
Fixed resizing of wf velocity.
Defined Matrix::operator=.
Fixed bug in PSD optimization: G=0 coefficient had zero value of dt2bye.

--------------------------------------------------------------------------------
rel1_8_0
Added thermostat, th_time, th_temp.
Added emass variable.
--------------------------------------------------------------------------------
rel1_7_1
Fixed bug in calculation of electronic kinetic energy in SampleStepper.C which
caused small kink in ekin_e and spike in econst during restarts.
--------------------------------------------------------------------------------
rel1_7_0
Implemented parallel XML preprocessing of sample files for fast loading.
Added -serial option to the load command to force serial parsing of files.
Fixed a bug in Context::string_send: was incorrect for zero-length strings
initialization of ibuf removed, unnecessary.
Added new dmin,dmax,imin,imax,string_send,string_recv,pmap functions in
Context
Changed the block distribution of the slabs in FourierTransform to adopt the
same type of block distribution used in ScaLAPACK. Needed in SampleReader.C
in order to read from the gfdata matrix.
--------------------------------------------------------------------------------
rel1_6_1exp
2003-07-24:modified initialization of coefficients in SlaterDet constructor
to choose g vectors of minimum norm. Note: reverting to -O2 option using xlC
after noting that -O3 causes incorrect results in testBasis.
Added dmin,dmax,imin,imax members to Context.C to identify process where
max or min is found.
--------------------------------------------------------------------------------
rel1_6_0
Implemented MD for wfs and for ions, print ekin_e, ekin_ion, econst in
SampleStepper.C. Use Stoermer's rule to compute velocities at end points.
Implemented load/save of wf velocities
--------------------------------------------------------------------------------
rel1_5_1
Fixed bug in NonLocalPotential that appeared for Contexts having multiple
columns and rows (computation of enl and fion incorrect).
--------------------------------------------------------------------------------
rel1_5_0    May 21, 2003
Parallel Load/Save XML sample implemented.
Load is slow: 6 min for 256 states on a (64)^3 grid (H2O_64, 73 Ry)
Save is ok (30 s.)
Bug found in NonLocalPotential::update_eigr: index of first local atom not
computed. Fixed. Affects calculations with multiple-column contexts.
Fixed bug in NonLocalPotential::energy: loop over fnl elements.
Added optional ecut attribute to the wavefunction element to insure
restart from xml sample in exact same conditions. If ecut attribute is not
specified in xml file, a value is inferred from the grid size.
Fixed incorrect initialization of dwf in EnergyFunctional::energy.
Implemented PSD for wf_dyn.
--------------------------------------------------------------------------------
rel1_4_0    May 16, 2003
Implemented byteswap operation when loading/saving XML base64 file on AIX.
(affects WavefunctionHandler.[Ch] and SlaterDet.[Ch].
All storage in base64 form is therefore little-endian. No byte swapping needed
on Intel platforms.
--------------------------------------------------------------------------------
rel1_3_0    May 16, 2003
New features in rel1_3_0:
XML input for sample, species, atomset, wavefunctions, including base64
encoding. New hiearchy of XML handler classes for parsing of sample files.
Parsing done with Apache xerces-c, 2.2.0.
Clean-up of FourierTransform: convention of fwd/bwd changed to be consistent
with usually accepted definitions (forward transform is Fourier analysis, i.e.
computation of Fourier coefficients, and involves scaling by 1/np012. Backward
transform is computation of real-space function from coefficients, no scaling).
Load command includes reading of sample and appropriate resizing of all
variables.
The "locked" variable is removed from the Atom class, and will be reintroduced
as a Constraint. This is to avoid having to include the "locked" info in the
XML definition of an Atom.
Builds and runs on Linux (linuc-pc_mpi_icc.mk) and on snow (aix_mpi.mk)
--------------------------------------------------------------------------------
Jan 24, 2003
Checking in release rel1_0_0:
performs SD steps with LDA and local pseudopotentials
--------------------------------------------------------------------------------
Thu Jan  9 16:01:42 PST 2003
Added UserInterface to qb. Commands Set, Print, Quit, Atom.
TO BE FIXED: SlaterDet cannot resize if more states than basis functions.
This forces the order in which ecut, cell and atoms are defined.
--------------------------------------------------------------------------------
Tue Sep 24 14:19:13 PDT 2002
SlaterDet can exist on any context.
Developing a Wavefunction that can hold any number of SlaterDets for
arbitrary nspin and nkpoints.
--------------------------------------------------------------------------------
