* Carpet: Do not count ghost zones when calculating speedErik Schnetter2012-09-11
| | | | When calculating the speed of a simulation, ignore ghost zones. Use two counters, one including the outer boundaries, the other excluding it.

* Re-organise time level handlingErik Schnetter2011-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Carpet: Simplify timer interfaceErik Schnetter2007-03-12
| | | | | | | | | | | | | | Remove parameter parameters Carpet::silent, which was inconvenient to use. Do not output timing statistics by default. Allow parameter values -1 in addition to 0 to disable timing output. Place the timing statistics into the grid scalars even if timing output is disabled. darcs-hash:20070312161517-dae7b-77a7d21f37179962beae2f544e7ee6a174c45508.gz

* Carpet: Change regridding API to use region_tErik Schnetter2007-01-13
| | | | | | | | | | Change the regridding API to use region_t. This is a major API change. Use the information in region_t to correct the load balancing when outer buffer zones are used. darcs-hash:20070113014409-dae7b-33f78948a7b826ea7806513d7864730fe64c14a9.gz
* Carpet: More work on timersErik Schnetter2006-07-27
| | | | | | | | | | | | Store physical timing information in grid scalars for easier output. Introduce a parameter "Carpet::silent" to switch off periodic output of the physical timing information. Add detailed timers for Carpet's main evolution loop, using Cactus timers. Their output would usually be written to files. darcs-hash:20060727165144-dae7b-aac1f402b3d23351153dfa8b48ee52a29d05e94e.gz
