New in version 4.2: * Removal of duplicated and unused routines * Major reorganization of the distribution itself: external packages no longer in the repository * New package GWW for GW calculations with Wannier functions * Grid parallelization for the phonon code, code cleanup * Better OpenMP+MPI parallelization * Real-space PP non-local projectors (experimental) * Martyna-Tuckerman algorithm for isolated systems * Better q=>0 limit for Exact-Exchange calculations * HSE functional * Bug fixes and output cleanup for cp.x autopilot * Parallel symmetrization in G-space Fixed in version 4.2: * A few occurrences of uninitialized variables and of incorrect INTENT * The value of DFT set in input (instead of DFT read from PP files) was ignored by all codes using the data file (phonon, postprocessing, etc) * PW: glitches in restart (now it works also with exact exchange) * D3: real-space contribution to the Ewald term was incorrect, since the initial release. Since such term is usually very small, the error was also very small. Also: preconditioning was not properly implemented, causing unnecessary slow convergence Incompatible changes in version 4.2: * changed defaults: startingwfc='atomic+random' in pw.x (instead of 'atomic') * calculations 'fpmd', 'fpmd-neb' removed from CP: use 'cp' or 'neb' instead * calculation 'metadyn' and related variables removed from PW and CP: use the "plumed" plugin for QE to perform metadynamics calculations * nelec, nelup, neldw, multiplicity variables removed from input: use tot_charge and tot_magnetization instead * calculation of empty Kohn-Sham states, and related variables, removed from cp.x: use option disk_io='high' in cp.x to save the charge density, read the charge density so produced with pw.x, specifying option "calculation='nscf'" or "calculation='bands'" * "xc_type" input variable in cp.x replaced by "input_dft" (as in pw.x) * ortho_para variable removed from input (CP); diagonalization='cg-serial', 'david-serial', 'david-para', 'david-distpara', removed as well Use command-line option "-ndiag N" or "-northo N" to select how many processors to use for linar-algebra (orthonormalization or subspace diagonalization) parallelization. Note that the default value for ndiag/northo has changed as well: 1 if ScaLAPACK is not compiled, Nproc/2 if Scalapack is compiled * "stm_wfc_matching" removed from pp.x |
