* Move MPI support from flesh to a thornErik Schnetter2012-07-21
| | | | | | | Move MPI support from flesh to thorn ExternalLibraries/MPI. This also requires thorns that call MPI directly to declare this in their configuration.ccl. Existing configurations using MPI need to include ExternalLibraries/MPI into their thorn list.

| | | | | WARN_DEBUG from WARN_PICKY since there might still be thorns around that do so

* CarpetLib: Change API to obtain pointer to grid function dataErik Schnetter2012-02-25
| | | | | | | | Change the API to obtain a pointer to grid function data: - Use a function "typed_data_pointer" instead of overloading the () operator (because this looks nicer) - Don't use a virtual function (because this isn't needed) - Update all uses
* CarpetReduce: Set up weight function correctly for 2D domainsErik Schnetter2012-01-11

* CarpetReduce: Use Carpet's MPI reduction operatorsErik Schnetter2011-11-14
| | | | | | Use Carpet's MPI reduction operators instead of the standard MPI operators, because the standard operators do not support complex numbers.
* CarpetMask: Keep track of the volume that is masked outErik Schnetter2011-11-09
| | | | | | Keep track of the volume that is masked out by CarpetMask, and take this volume into account when checking in CarpetReduce that the integral over the simulation domain equals the domain volume.

* CarpetMask CarpetReduce: New schedule bin SetupIMaskErik Schnetter2011-08-10
| | | | | | For consistency reasons, CarpetReduce sets up the reduction mask (weight function) partly using an integer bit field, partly using a real-values mask. Introduce separate groups for each.
* CarpetReduce: Correct boundary sizes in reduction mask setupErik Schnetter2011-06-23
| | | | The previous commit had an error.
* Erik's patch to fix a reduction operator problem.Christian Reisswig2011-06-07
| | | | Without this fix, reductions may depend on the number of processors used.
* CarpetReduce: Rewrite prolongation and reduction mask handlingErik Schnetter2011-05-22

* Re-organise time level handlingErik Schnetter2010-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Store the current Cactus time (and not a fake Carpet time) in the th "time hiearchy". This removes the now redundant "leveltimes" data structure in Carpet. Add past time levels to th, so that it can store the time for past time levels instead of assuming the time step size is constant. This allows changing the time step size during evolution. Share the time hierarchy between all maps, instead of having one time hierarchy per map. Simplify the time level cycling and time stepping code used during evolution. Improve structure of the code that loops over time levels for certain schedule bins. Introduce a new Carpet variable "timelevel", similar to "reflevel". This also makes it possible to avoid time interpolation for the past time levels during regridding. The past time levels of the fine grid then remain aligned (in time) with the past time levels of the coarse grid. This is controlled by a new parameter "time_interpolation_during_regridding", which defaults to "yes" for backwards compatibility. Simplify the three time level initialisation. Instead of initialising all three time levels by taking altogether three time steps (forwards and backwards), initialise only one past time level by taking one time step backwards. The remaining time level is initialised during the first time step of the evolution, which begins by cycling time levels, which drops the non-initialised last time level anyway. Update Carpet and the mode handling correspondingly. Update the CarpetIOHDF5 checkpoint format correspondingly. Update CarpetInterp, CarpetReduce, and CarpetRegrid2 correspondingly. Update CarpetJacobi and CarpetMG correspondingly.
