CONFIGURATION FILES
|
|
|
|
You shouldn't need to edit the following files. The first three
|
|
are automatically generated by "configure".
|
|
|
|
* include/configure.h
|
|
==================
|
|
automatically generated by configure using include/configure.h.in
|
|
as template - contains compilation info, usable for initial printout
|
|
(define __HAVE_CONFIG_INFO in Modules/environ.f90 to use it)
|
|
|
|
* include/qe_cdefs.h
|
|
================
|
|
automatically generated by configure using include/qe_cdefs.h.in
|
|
as template - included in C files in clib/ . Contains:
|
|
#define HAVE_MALLINFO
|
|
if the mallinfo structure is present (e.g. Linux)
|
|
|

PREPROCESSING OPTIONS USED IN *.h FILES AND IN THE SOURCES
|
|
|
|
Predefined by specific compilers:
|
|
_OPENMP OpenMP parallelization (all compilers)
|
|
__GFORTRAN__ GNU gfortran
|
|
__INTEL_COMPILER Intel compiler
|
|
|
|
Hardware / Compiler:
|
|
__AIX Ibm rs/6000 machines (obsolescent)
|
|
__PGI Portland Group compiler workarounds for compiler bugs
|
|
_WIN32 Windows 32-bits
|
|
|
|
New algorithms:
|
|
__NON_BLOCKING_SCATTER Use non-blocking algorithm for parallel FFTs
|
|
__DOUBLE_BUFFER Use double buffer algorithm for parallel FFTs
|
|
|
|
Parallel execution:
|
|
__MPI MPI parallelization
|
|
__MPI_MODULE Compile with "USE mpi" instead of "include 'mpif/h'"
|
|
__MPI_NONBLOCKING Use nonblocking routines (e.g. mpi_ibcast, mpi_igatherv)
|
|
|
|
Libraries:
|
|
__FFTW FFT routines from internal FFTW library (default)
|
|
__FFTW3 FFT routines from external FFTW v.3 library
|
|
__DFTI FFT routines from Intel MKL library
|
|
__ARM_LIB EFT routines from ARM Performance library
|
|
__LINUX_ESSL Use blas/lapack/fft routines from IBM ESSL library
|
|
(linux version; aix version no longer supported)
|
|
__SCALAPACK Use Scalapack routines instead of internal ones
|
|
for parallel subspace diagonalization
|
|
__ELPA_2015 Use ELPA library (version 2015, backward compatibility)
|
|
__ELPA_2016 Use ELPA library (version 2016, supported)
|
|
__MASS Use mathematical routines from IBM MASS library
|
|
__SX6 Use MathKeisan libraries for NEC SX machines
|
|
ASL, MICRO SX-6 specific libraries (obsolescent)
|
|
|
|
Signals:
|
|
__PTRACE Enable traceback
|
|
__TRAP_SIGUSR1 Enable signal trapping (experimental): code will stop
|
|
and save data if executable is signaled with USR1
|
|
IO / Reporting:
|
|
__HDF5 Enable I/O using parallel HDF5 (Fortran 2003
|
|
features needed to compile)
|
|
__CLOCK_SECONDS Translate clock from HH:mm:ss to only seconds
|
|
|
|
All other preprocessing flags are for debugging purposes and should not be
|
|
used unless you know what you are doing
