#-----------------------------------------------------------------------
#
# Brief guide to compile-time options of the code. More information
# can be found in the code documentation.
#
# - PERIODIC:
# Set this if you want to have periodic boundary conditions.
#
# - UNEQUALSOFTENINGS:
# Set this if you use particles with different gravitational
# softening lengths.
#
# - PEANOHILBERT:
# This is a tuning option. When set, the code will bring the
# particles after each domain decomposition into Peano-Hilbert
# order. This improves cache utilization and performance.
#
# - WALLCLOCK:
# If set, a wallclock timer is used by the code to measure internal
# time consumption (see cpu-log file). Otherwise, a timer that
# measures consumed processor ticks is used.
#
# - PMGRID:
# This enables the TreePM method, i.e. the long-range force is
# computed with a PM-algorithm, and the short range force with the
# tree. The parameter has to be set to the size of the mesh that
# should be used, (e.g. 64, 96, 128, etc). The mesh dimensions need
# not necessarily be a power of two. Note: If the simulation is
# not in a periodic box, then a FFT method for vacuum boundaries is
# employed, using an actual mesh with dimension twice(!) that
# specified by PMGRID.
#
# - PLACEHIGHRESREGION:
# If this option is set (will only work together with PMGRID), then
# the long range force is computed in two stages: One Fourier-grid
# is used to cover the whole simulation volume, allowing the
# computation of the longe-range force. A second Fourier mesh is
# placed on the region occupied by "high-resolution" particles,
# allowing the computation of an intermediate scale force. Finally,
# the force on short scales is computed with the tree. This
# procedure can be useful for "zoom-simulations", provided the
# majority of particles (the high-res particles) are occupying only
# a small fraction of the volume. To activate this option, the
# parameter needs to be set to an integer bit mask that encodes the
# particle types that make up the high-res particles.
# For example, if types 0, 1, and 4 form the high-res
# particles, set the parameter to PLACEHIGHRESREGION=19, because
# 2^0 + 2^1 + 2^4 = 19. The spatial region covered by the high-res
# grid is determined automatically from the initial conditions.
# Note: If a periodic box is used, the high-res zone may not intersect
# the box boundaries.
#
# - ENLARGEREGION:
# The spatial region covered by the high-res zone has a fixed size
# during the simulation, which initially is set to the smallest
# region that encompasses all high-res particles. Normally, the
# simulation will be interrupted if high-res particles leave this
# region in the course of the run. However, by setting this
# parameter to a value larger than one, the size of the high-res
# region can be expanded, providing a buffer region. For example,
# setting it to 1.4 will enlarge its side-length by 40% (it remains
# centered on the high-res particles). Hence, with this setting, the
# high-res region may expand or move by a limited amount.
# Note: If SYNCHRONIZATION is activated, the code will be able to
# continue even if high-res particles leave the initial high-res
# grid. In this case, the code will update the size and position of
# the grid that is placed onto the high-resolution region
# automatically. To prevent that this potentially happens every
# single PM step, one should nevertheless assign a value slightly
# larger than 1 to ENLARGEREGION.
#
# - ASMTH:
# This can be used to override the value assumed for the scale that
# defines the long-range/short-range force-split in the TreePM
# algorithm. The default value is 1.25, in mesh-cells.
#
# - RCUT:
# This can be used to override the maximum radius in which the
# short-range tree-force is evaluated (in case the TreePM algorithm
# is used). The default value is 4.5, given in mesh-cells.
#
# - DOUBLEPRECISION:
# This makes the code store and compute internal particle data in
# double precision. Note that output files are nevertheless written
# by converting the particle data to single precision.
#
# - DDOUBLEPRECISION_FFTW:
# If this is set, the code will use the double-precision version of
# FTTW, provided the latter has been explicitly installed with a
# "d" prefix, and NOTYPEPREFIX_FFTW is not set. Otherwise the
# single precision version ("s" prefix) is used.
#
# - SYNCHRONIZATION:
# When this is set, particles are kept in a binary hierarchy of
# timesteps and may only increase their timestep if the new
# timestep will put them into synchronization with the higher time
# level.
#
# - FLEXSTEPS:
# This is an alternative to SYNCHRONIZATION. Particle timesteps are
# here allowed to be integer multiples of the minimum timestep that
# occurs among the particles, which in turn is rounded down to the
# nearest power-of-two devision of the total simulated
# timespan. This option distributes particles more evenly over
# individual system timesteps, particularly once a simulation has
# run for a while, and may then result in a reduction of work-load
# imbalance losses.
#
# - PSEUDOSYMMETRIC:
# When this option is set, the code will try to "anticipate"
# timestep changes by extrapolating the change of the acceleration
# into the future. This can in certain idealized cases improve the
# long-term integration behaviour of periodic orbits, but should
# make little or no difference in most real-world applications. May
# only be used together with SYNCHRONIZATION.
#
# - NOSTOP_WHEN_BELOW_MINTIMESTEP:
# If this is activated, the code will not terminate when the
# timestep falls below the value of MinSizeTimestep specified in
# the parameterfile. This is useful for runs where one wants to
# enforce a constant timestep for all particles. This can be done
# by activating this option, and by setting MinSizeTimestep and
# MaxSizeTimestep to an equal value.
#
# - NOPMSTEPADJUSTMENT:
# When this is set, the long-range timestep for the PM-force
# computation (when the TreePM algorithm is used) is always
# determined by MaxSizeTimeStep. Otherwise, it is determined by
# the MaxRMSDisplacement parameter, or MaxSizeTimeStep, whichever
# gives the smaller step.
#
# - HAVE_HDF5:
# If this is set, the code will be compiled with support for input
# and output in the HDF5 format. You need to have the HDF5
# libraries and headers installed on your computer for this option
# to work. The HDF5 format can then be selected as format "3" in
# Gadget's parameterfile.
#
# - OUTPUTPOTENTIAL:
# This will make the code compute gravitational potentials for
# all particles each time a snapshot file is generated. The values
# are then included in the snapshot file. Note that the computation
# of the values of the gravitational potential costs additional CPU.
#
# - OUTPUTACCELERATION:
# This will include the physical acceleration of each particle in
# snapshot files.
#
# - OUTPUTCHANGEOFENTROPY:
# This will include the rate of change of entropy of gas particles
# in snapshot files.
#
# - OUTPUTTIMESTEP:
# This will include the current timesteps of all particles in the
# snapshot files.
#
# - NOGRAVITY
# This switches off gravity. Useful only for pure SPH simulations
# in non-expanding space.
#
# - NOTREERND:
# If this is not set, the tree construction will succeed even when
# there are a few particles at identical locations. This is done by
# `rerouting' particles once the node-size has fallen below 1.0e-3
# of the softening length. When this option is activated, this will
# be surpressed and the tree construction will always fail if there
# are particles at extremely close coordinates.
#
# - NOTYPEPREFIX_FFTW:
# This is an option that signals that FFTW has been compiled
# without the type-prefix option, i.e. no leading "d" or "s"
# characters are used to access the library.
#
# - LONG_X/Y/Z:
# These options can be used together with PERIODIC and NOGRAVITY only.
# When set, the options define numerical factors that can be used to
# distorts the periodic simulation cube into a parallelepiped of
# arbitrary aspect ratio. This can be useful for idealized SPH tests.
#
# - TWODIMS:
# This effectively switches of one dimension in SPH, i.e. the code
# follows only 2d hydrodynamics in the xy-, yz-, or xz-plane. This
# only works with NOGRAVITY, and if all coordinates of the third
# axis are exactly equal. Can be useful for idealized SPH tests.
#
# - SPH_BND_PARTICLES:
# If this is set, particles with a particle-ID equal to zero do not
# receive any SPH acceleration. This can be useful for idealized
# SPH tests, where these particles represent fixed "walls".
#
# - NOVISCOSITYLIMITER:
# If this is set, the code will not try to put an upper limit on
# the viscous force in case an implausibly high pair-wise viscous
# force (which may lead to a particle 'reflection' in case of poor
# timestepping) should arise. Note: For proper settings of the
# timestep parameters, this situation should not arise.
#
# - COMPUTE_POTENTIAL_ENERGY:
# When this option is set, the code will compute the gravitational
# potential energy each time a global statistics is computed. This
# can be useful for testing global energy conservation.
#
# - LONGIDS:
# If this is set, the code assumes that particle-IDs are stored as
# 64-bit long integers. This is only really needed if you want to
# go beyond ~2 billion particles.
#
# - ISOTHERM_EQS:
# This special option makes the gas behave like an isothermal gas
# with equation of state P = cs^2 * rho. The sound-speed cs is set by
# the thermal energy per unit mass in the intial conditions,
# i.e. cs^2=u. If the value for u is zero, then the initial gas
# temperature in the parameter file is used to define the sound speed
# according to cs^2 = 3/2 kT/mp, where mp is the proton mass.
#
# - ADAPTIVE_GRAVSOFT_FORGAS:
# When this option is set, the gravitational softening lengths used for
# gas particles is tied to their SPH smoothing length. This can be useful
# for dissipative collapse simulations. The option requires the setting
# of UNEQUALSOFTENINGS.
#
# - SELECTIVE_NO_GRAVITY:
# This can be used for special computations where one wants to
# exclude certain particle types from receiving gravitational
# forces. The particle types that are excluded in this fashion are
# specified by a bit mask, in the same as for the PLACEHIGHRESREGION
# option.
#
# - FORCETEST:
# This can be set to check the force accuracy of the code. The
# option needs to be set to a number between 0 and 1 (e.g. 0.01),
# which is taken to specify a random fraction of particles for
# which at each timestep forces by direct summation are
# computed. The normal tree-forces and the correct direct
# summation forces are collected in a file. Note that the
# simulation itself is unaffected by this option, but it will of
# course run much(!) slower, especially if
# FORCETEST*NumPart*NumPart >> NumPart. Note: Particle IDs must
# be set to numbers >=1 for this to work.
#
# - MAKEGLASS
# This option can be used to generate a glass-like particle
# configuration. The value assigned gives the particle load,
# which is initially generated as a Poisson sample and then
# evolved towards a glass with the sign of gravity reversed.

* \brief declares global variables.
*
* This file declares all global variables. Further variables should be added here, and declared as
* 'extern'. The actual existence of these variables is provided by the file 'allvars.c'. To produce
* 'allvars.c' from 'allvars.h', do the following:
*
* - Erase all #define's, typedef's, and enum's
* - add #include "allvars.h", delete the #ifndef ALLVARS_H conditional
* - delete all keywords 'extern'
* - delete all struct definitions enclosed in {...}, e.g.
* "extern struct global_data_all_processes {....} All;"
* becomes "struct global_data_all_processes All;"

* \brief code for domain decomposition
*
* This file contains the code for the domain decomposition of the
* simulation volume. The domains are constructed from disjoint subsets
* of the leaves of a fiducial top-level tree that covers the full
* simulation volume. Domain boundaries hence run along tree-node
* divisions of a fiducial global BH tree. As a result of this method, the
* tree force are in principle strictly independent of the way the domains
* are cut. The domain decomposition can be carried out for an arbitrary
* number of CPUs. Individual domains are not cubical, but spatially
* coherent since the leaves are traversed in a Peano-Hilbert order and
* individual domains form segments along this order. This also ensures
* that each domain has a small surface to volume ratio, which minimizes
* communication.
