* CarpetLib: Change meaning of vect::count to count true (non-zero) elementsErik Schnetter2013-05-20
| | | | Change count() from counting all elements, which is already done by size(), to counting true (non-zero) elements, which is what Fortran's count() does as well.
* CarpetLib: Rename vect::zip to vect::vzipErik Schnetter2013-05-20
| | | | vect::map is already called vect::vmap.
* CarpetLib: Add constructors to create a vector from a low-dimensional vector ↵Erik Schnetter2013-05-20

* Replace abs() by fabs()Erik Schnetter2013-04-02

* 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.

| | | | | Introduce a new function vect<T,D>::index(lsh,ind), which calculates the linear grid point index given the array size and an index triplet.
* 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

| | | | | | | | | Define vect<T,D> functions with macros. Define many vect<T,D> functions also for vect<vect<T,D>,E> and for combinations with scalars. darcs-hash:20070419014657-dae7b-b3c62cc55963872a39cd48439c2057918578eda3.gz
* CarpetLib: Updates to vect classErik Schnetter2007-01-12
| | | | | | | | Add some new functions to make the vect class more convenient. Remove some unused functions. Instantiate some more templates. darcs-hash:20070112205505-dae7b-12a0ea160b9740cdbe60d89d9e9100fc06a1faa7.gz
* CarpetLib: Add placeholders for "const" and "pure" attributes to vect<T>Erik Schnetter2006-07-31
| | | | | | | | | Add __attribute__((const)) and __attribute__((pure)) to vect<T> functions where appropriate. These attributes are not active, because it is not clear that this really improves performance, and errors could lead to wrong code. darcs-hash:20060731152218-dae7b-20c523f60890b2ad611157764e0b993bfb185c8d.gz
* CarpetLib: Move arithmetic operations out of vect classErik Schnetter2006-06-05
| | | | | | | | | Move the arithmetic operations (+-*/ etc.) out of the vect class. Instead of member functions, they are now standalone functions. This makes it possible to write "int * vect<int>" with automatic conversion. darcs-hash:20060605220401-dae7b-eee6ed411e3d0e5850dd8e6bd85d432eed4752e8.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

* Many changes that accumulated while Cactus and Carpet diverged.schnetter2003-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many changes that accumulated while Cactus and Carpet diverged. Add processor splitting mechanism "along-dir" that splits along a specified direction. Rename group PostRestrict to bin POSTRESTRICT. Prolongate initial data only when desired. This saves much time. Sorry, Ian. Fix bug in time level cycling of grid arrays. (Note: grid arrays should not have time levels.) Fix time_t bug on IRIX. Make sure that there is no integer overflow when there are many refinement levels. Always put parentheses around (maxreflevelfact/reflevelfact). Fix typo in Carpet verbose output. Add debug output in processor splitting. Communicate in three stages: Irecv, (work), Isend, Wait. This might be more efficient. Much more, potentially. Fix bug in processor layout of grid arrays. Sorry, Ian. Make the interpolator interpolate between time levels. Untested. Fix bug in processor communication in interpolator. Sorry, Ian. Rewrite prolongation operators to make them twice as fast. There you are, Ian. Move prolongation operator kind handling from data to gdata. Add official hyperslabbing interfaces to CarpetSlab. Adapt to new cGH * handling. darcs-hash:20031105151837-07bb3-758a87ff0355dba053269df4b7d7d79bea018669.gz
