* CarpetLib: use map instead of set for dh::gfsRoland Haas2013-10-15
| | | | | some routines assume that elements in gfs are sorted by variable index when traversing the container (eg recompose_allocate does)
* CarpetLib: Provide manual look-alikes for certain C++11 featuresErik Schnetter2013-06-08
| | | | | Provide "forall" based on Boost's FOREACH. Provide shared_ptr based on Boost's shared_ptr.
* CarpetLib: Disable bboxset2 by defaultErik Schnetter2013-05-26
| | | | Change from CARPET_NO_BBOXSET2 and CARPET_BBOXSET2 to CARPET_ENABLE_BBOXSET2 (build it) and CARPET_USE_BBOXSET2 (use it).
* CarpetLib: New class bboxset2Erik Schnetter2013-05-26
| | | | | | | | | | Rename bboxset to bboxset1. Implement new class bboxset2, which uses a different internal datastructure than bboxset1. Make bboxset a typedef for either bboxset1 (default) or bboxset2, as selected by the compile-time macro CARPET_BBOXSET2. Disable all bboxset2 code if CARPET_NO_BBOXSET2 is given, since bboxset2 uses newer C++ constructs not available on some older compilers.
* CarpetLib: Use C++ standard methods to compare containersErik Schnetter2013-05-26
| | | | | Remove CarpetLib's "equals" method. Implement equal_to, less, greater, greater_equal, less_equal, not_equal for vect and bbox classes.
* CarpetLib: Add routines for integer division that always round downErik Schnetter2013-05-20
| | | | Standard integer division truncates, which can lead to problems if an intermediat result is negative.
* CarpetLib: Correct isnorma() for complex numbersErik Schnetter2013-05-20
|
* CarpetLib: Don't define static_assertErik Schnetter2013-05-20
| | | | This should now be done by the flesh, using autoconf.
* CarpetLib: Don't explicitly #include cctk_Config.hErik Schnetter2013-05-20
| | | | This is done by cctk.h automatically.
* CarpetLib: Rewrite array paddingErik Schnetter2013-01-16
| | | | | Obtain cache information from thorn hwloc. Align allocated memory manually if operator new returns unaligned memory.
* Remove Carpet's mechanisms to deal with how to call isnanErik Schnetter2012-10-22
| | | | Remove Carpet's mechanisms to deal with how to call isnan. Instead, expect isnan in std::, and rely on Cactus to correct things if this is not the case.
* CarpetLib: Remove redefinition of restrict qualifierErik Schnetter2012-09-11
|
* CarpetLib: Remove superfluous memoryof() definitionsErik Schnetter2012-09-11
| | | | | Remove definitions for memoryof(T*) sinfc there is already memoryof(T const*). xlC does not like having both.

* CarpetLib: Define new macro "check(expr)" to check the return values easilyErik Schnetter2008-10-10
| | | | | | The new macro check(expr) evaluates the expression expr, and then asserts that it is true. If assertions are disabled the expression is still evaluated.
* Move definition of rvect, jvect etc. from Carpet to CarpetLib.Erik Schnetter2008-07-14
| | | | Remove include file defines.hh in Carpet.
* Introduce a tree data structure to speed up domain decompositionErik Schnetter2008-06-20
| | | | | | | | | Introduce a tree data structure "fulltree", which decomposes a single, rectangular region into a tree of non-overlapping, rectangular sub-regions. Move the processor decomposition from the regridding thorns into Carpet. Create such trees during processor decomposition. Store these trees with the grid hierarchy.
* CarpetLib: Add function memoryof to measure size of data structuresErik Schnetter2008-02-02
| | | | | | | Add an overloaded function memoryof which measures the size in bytes of CarpetLib's data structures. darcs-hash:20080202154302-dae7b-de41c79cb04617327695fae27928c05c5d431ee8.gz
* CarpetLib: Update defsErik Schnetter2007-04-19
| | | | darcs-hash:20070419014930-dae7b-3584da98807f38935aa636d7608c1baf3fa51336.gz
* CarpetLib: Use CARPET_DEBUG and CARPET_OPTIMISE instead of NDEBUGErik Schnetter2007-03-04
| | | | | | | | | Use CARPET_DEBUG and CARPET_OPTIMISE (instead of NDEBUG) to decide whether to perform or omit somewhat expensive self checks. When CARPET_DEBUG is defined, even expensive checks are performed. When CARPET_OPTIMISE is defined, even cheap checks are omitted. darcs-hash:20070304211311-dae7b-ae917b0f40496fedf4bb5d1c2a70ad31a5167ca3.gz
* CarpetLib: Change static_assert to have two argumentsErik Schnetter2007-02-28
| | | | | | | Change static_assert to have a second arguments, which is supposed to be a string containing a description of the test. darcs-hash:20070228022658-dae7b-3fb68ea0e0f557f2268cb95546ba0d70c58cda7a.gz
* CarpetLib: Define overloaded abs functions for all Cactus datatypesErik Schnetter2007-02-28
| | | | | | | | | Add namespace CarpetLib::good containing overloaded abs functions for all Cactus datatypes. Some C++ compilers do not have long long support for abs, i.e., either std::abs or llabs does not exist. This circumvents this problem. darcs-hash:20070228022422-dae7b-a4cafbbad3f8b9cf9ae56edcc2f30c72c0d8de05.gz
* CarpetLib: Some minor whitespace changesErik Schnetter2007-02-04

* CarpetLib: Remove commented out code for complex variablesErik Schnetter2007-02-04
| | | | | | | | | CarpetLib contained special code that used std::complex instead of Cactus's CCTK_COMPLEX for complex variables. A very similar feature is now supposed to go into the flesh, and hence this (unused) code is being removed. darcs-hash:20070204172854-dae7b-af7b7aca42988195846220dd7f45827549f5caf9.gz
* CarpetLib: Use AT to index std::vectorErik Schnetter2007-02-03
| | | | | | | | Define a macro AT() to index into std::vector. Depending on the macro NDEBUG, AT() is defined either as at(), providing index checking, or as operator[], providing no checking. darcs-hash:20070203205854-dae7b-a1999c88c95ba12b1ee66505f712aefdd67d7e6f.gz
* CarpetLib: Define constant eolErik Schnetter2007-02-03
| | | | | | | Define a constant eol containing a newline character. Unlike endl, it does not flush the I/O stream. darcs-hash:20070203185434-dae7b-1f057e593cc45b3d5cf1b067b247b6de071230da.gz

| | | | darcs-hash:20070115175330-dae7b-ae3dd3c47931ad57b3a5cca9429b3f223c9e834c.gz
* CarpetLib: Add consume() routine for stringsErik Schnetter2007-01-12
| | | | | | | Add a routine consume() which reads a whole string, not only a single character. darcs-hash:20070112210808-dae7b-dc1e0be61cefe8af390d9f598bfdac314dd7aeac.gz
* CarpetLib: Reorganise prolongation and restriction operatorsErik Schnetter2007-01-12
| | | | | | | | | | | | | | | | | | | | | | | | Reorganise prolongation and restriction operators. This is a major implementation change. Most operators are now written as C++ templates instead of as Fortran 77 code. This simplifies the code, since C++ routines can be called more easily, and they also have access to CarpetLib's high-level data structures. Previously, the operators combined temporal and spatial interpolation. Now, time interpolation and space interpolation are handled separately. This may be less efficient, but simplifies the code significantly, since there are now N+M instead of N*M routines, for N time interpolation and M space interpolation methods. Remove the minmod prolongation operator, which was previously disabled. Add support for cell centering, using a method described by Simon Hern, and suggested for Carpet by Ian Hawke. darcs-hash:20070112205812-dae7b-5329795aa698e7bbc3671b1504134885dd830238.gz
* CarpetLib: Add new datatype region_tErik Schnetter2007-01-12
| | | | | | | | | | | | | | | | | | | | | | | The new datatype region_t combines an extent (a bbox), an outer boundary descriptor, a refinement descriptor, and a processor number: struct region_t { ibbox extent; // extent b2vect outer_boundaries; // outer boundaries b2vect refinement_boundaries; // refinement boundaries int map; // map to which this // region belongs int processor; // processor number }; These quantities are often used together, and combining them into a single datatype simplifies the code significantly. Adapt gh, dh, etc. to use this new datatype. This is a major API change. darcs-hash:20070112204130-dae7b-92cad546187b0fe499e8cfc38b2e26614a4f608c.gz

* CarpetLib: Introduce new types b2vect and i2vectErik Schnetter2005-08-08
| | | | | | | | | | | | These types are typedef vect<vect<bool,dim>,2> b2vect; typedef vect<vect<int,dim>,2> i2vect; They are similar to bbvect and iivect, but have the order reversed. They are useful if you need one element per face of a grid variable. darcs-hash:20050808132221-891bb-fa40b6d4fb8e760c7005adf7e526dd0a6597f0ec.gz
* global: Turn CarpetLib templates into classesErik Schnetter2005-01-01
| | | | | | | | | | | | | | | | | | | Turn most of the templates in CarpetLib, which used to have the form template<int D> class XXX into classes, i.e., into something like class XXX by setting D to the new global integer constant dim, which in turn is set to 3. The templates gf and data, which used to be of the form template<typename T, int D> class XXX are now of the form template<typename T> class XXX The templates vect, bbox, and bboxset remain templates. This change simplifies the code somewhat. darcs-hash:20050101182234-891bb-c3063528841f0d078b12cc506309ea27d8ce730d.gz

* Import the recently announced changes:schnetter2004-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Import the recently announced changes: 1. Carpet has now an infrastructure for multiple maps (aka "grid patches"). Instead of a single grid hierarchy there can now be several. This is largely untested, because the remainder of Cactus cannot handle multiple coordinate systems. 2. The order in which the schedule bins are called has changed. As Ian Hawke pointed out, the previous order during time evolution was inconsistent. The initial data ordering did not allow for recovering and was not usable for progressively solving elliptic equations for initial data. 3. Carpet now supports convergence levels. The convergence level specifies by how many factors of two the resolution in the parameter file should be coarsened (or refined, if negative). This should make convergence tests and test runs much easier. It is, in principle, also possible to run several convergence levels at once. This has not been tested because the remainder of Cactus cannot handle multiple resolutions. This will be necessary for a multigrid solver, and also for having a shadow hierarchy to determine where to refine adaptively. 4. Carpet works together with the new CoordBase domain specification parameters. Without these, using convergence levels will lead to very strange results. 5. The "modes" have changed. There are now: meta mode: the whole simulation global mode: one convergence level level mode: one refinement level singlemap mode: one map on one refinement level local mode: as previously The whole mode handling has been cleaned up. 6. The regridding thorn has been cleaned up. 7. The kind of prolongation stencil is now determined in Carpet, i.e. at a fairly hight level, instead of in CarpetLib. 8. The low-order prolongation operators have been made much more efficient (as have previously the higher-order ones). 9. Assorted smaller changes. For Carpet users, there should be no major incompatibilities. The major improvements are 3 and 4 combined. Here is an example: CoordBase::domainsize = extent CoordBase::spacing = gridspacing CoordBase::zero_origin_x = yes CoordBase::zero_origin_y = yes CoordBase::zero_origin_z = yes CoordBase::xextent = 20.0 CoordBase::yextent = 20.0 CoordBase::zextent = 20.0 CoordBase::dx = 1.0 CoordBase::dy = 1.0 CoordBase::dz = 1.0 CoordBase::boundary_shiftout_x_lower = 1 CoordBase::boundary_shiftout_y_lower = 1 CoordBase::boundary_shiftout_z_lower = 1 Carpet::domain_from_coordbase = yes Carpet::convergence_level = 0 grid::type = coordbase grid::domain = octant grid::avoid_origin = no This gives you a grid that extends from the origin ("zero_origin") up to 20.0 with a grid spacing of 1.0. Symmetry zones and boundary zones are added automatically. The "shiftout" says that there is no boundary point on the origin. The staggering parameters (not shown) default to "no". In order to change the resolution, only the convergence level has to be adjusted. Note that the old way of specifying the domain extent still works. For Carpet developers, one major change is the new mode handling. As described in 5, the looping macros (that loop over all refinement levels, or all components) have changed. darcs-hash:20040125135727-07bb3-51c9647c1b5080e7e180b52a1b81fa155cfd19e9.gz
