* CarpetLib: Introduce pseudoregion classErik Schnetter2007-02-04
| | | | | | | | | | | | | A pseudoregion is almost a region; it is a bbox that lives on a certain processor. Pseudoregions are a compact way to store information about what processors needs to send data to what other processor during synchronisation or regridding. Introduce a class pseudoregion. Add additional pseudoregion fields to the dh class. Use these fields when communicating; this is faster than walking the original data structures. darcs-hash:20070204184339-dae7b-3bd90a48b77cf0623e3df3a7ca4edd9d5c7053f8.gz

* CarpetLib: Clean up transport operatorsErik Schnetter2007-02-04
| | | | | | | | | | | | Remove unused, #ifdef'ed out code from the operators. Since the operators use now the bbox class, this checking is already performed there. Remove unused debugging code in the cell-centered operators. Use the restrict qualifier in the prototypes. darcs-hash:20070204174027-dae7b-743583b30d52646219411c98ad99486d10445e52.gz
* 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: Improve timersErik Schnetter2007-02-03
| | | | | | | | | | | | Implement a second timer based on Intel's rdtsc instruction, which is much faster and much more accurate than MPI_Wtime. Place the timer classes into the CarpetLib namespace. Create a TimerSet class. Make the Timer class automatically register all timers with a singleton object, removing all global variables. darcs-hash:20070203211128-dae7b-42765e79446eda6a2337ba22cd390869055c555a.gz

* CarpetLib: Use AT to index std::vectorErik Schnetter2007-02-03

* CarpetLib: Optimise bbox and bboxset classes for speedErik Schnetter2007-02-03
| | | | | | | | | | | | | Use std::list instead of std::set to store the bboxes internally. Define some functions as inline. Perform some checking only when NDEBUG is not defined. Optimise the algorithms for normalising bboxsets and for calculating the set difference. darcs-hash:20070203172717-dae7b-1e77f0a810f786913cd2a1aaed1ea1a5fde604cf.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: Split recompose functions into regrid and recomposeErik Schnetter2006-09-04
| | | | | | | | | | | | | | | Split recompose functions into two stages, regrid and recompose. The first stage, regrid, changes the grid structure in the gh and dh classes. The second stage, recompose, changes the values of the actual grid functions, i.e., changes the gf<T> and data<T> objects. The second stage has to be called individually for every refinement level. This is necessary since the boundary conditions need to be applied after recomposing one refinement level, before the next fine refinement level can be recomposed. darcs-hash:20060904230433-dae7b-3ba1982460f57b34da11a6fbb6b4b524dc5b348f.gz

* [CarpetLib] add option to omit Fortran 90 files by adding -DOMIT_F90 to ↵Jonathan Thornburg2006-08-29
| | | | | | | | | | | | | | | | | | | | | | | | compiler flags Carpet is _almost_ entirely written in C, C++, and Fortran 77, but there are a few Fortran 90 files in CarpetLib defining the ENO and WENO prolongation operators. This patch allows Carpet to be compiled without a Fortran 90 compiler if these (ENO/WENO) operators are not needed, by defining the C preprocessor symbol OMIT_F90. For example, you could do this by putting CFLAGS=-DOMIT_F90 CXXFLAGS=-DOMIT_F90 F77FLAGS=-DOMIT_F90 F90FLAGS=-DOMIT_F90 in a ~/.cactus/config file. I emphasize that in the default case, where OMIT_F90 is not defined, this patch is a no-op: the ENO and WENO prolongation operators are still defined, a Fortran 90 compiler is still needed to compile CarpetLib, you still pass go, you still collect $200. :) This patch only changes the behavior of Carpet in the non-default case where OMIT_F90 is defined. darcs-hash:20060829170502-b0a3f-0d423f190bd7388faa9e1a6e0a980694b044516b.gz

| | | | | | | | | Poison newly allocated memory if desired. This is potentially more thorough that Carpet's poisoning, since it is applied to all allocated memory.
