* CarpetIOHDF5: Set times correctly after recoveringErik Schnetter2011-12-14
| | | | | | Recovery happens level-by-level in Cactus. When recovering the refinement level times and the global time, set them correctly according to the current refinement level.

* CarpetIOHDF5: Index file supportIan Hinder2011-12-14
| | | | | | | | | | | | | Scanning the attributes of a large CarpetIOHDF5 output file, as is necessary in the visitCarpetHDF5 plugin, can be very time consuming. This commit adds support for writing an "index" HDF5 file at the same time as the data file, conditional on a parameter "CarpetIOHDF5::output_index". The index file is the same as the data file except it contains null datasets, and hence is very small. The attributes can be read from this index file instead of the data file, greatly increasing performance. The datasets will have size 1 in the index file, so an additional attribute (h5space) is added to the dataset to specify the correct dataset dimensions.

* 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.

* CarpetIOHDF5: Allow different numbers of ghost zones on different levelsErik Schnetter2011-12-14
| | | | | | | Allow different numbers of ghost zones and different spatial prolongation orders on different refinement levels. This causes incompatible changes to the checkpoint file format.
* CarpetIOHDF5: Increase output accuracy for time hierarchyErik Schnetter2011-12-14
| | | | | | Serialise the time hierarchy with 17 digits of accuracy, instead of the standard 6 digits. This is required for correctly recovering the time hierarchy.
* CarpetIOHDF5: Rename some parametersErik Schnetter2011-12-14
| | | | | | Rename out3D_ghosts to output_ghost_points. Rename out3D_outer_ghosts to output_boundary_points. Keep the old parameter name for compatibility.
* CarpetIOHDF5: Output a warning if multiple input files need to be readErik Schnetter2011-12-14
| | | | | | | Output a warning message if multiple input files need to be read from one MPI process, since this is usually very slow. When reading files from the same number of processes that wrote them, each process is only supposed to need to open one file.

| * CarpetIOHDF5: fix a bug in the recovery of multipatch simulationsThomas Radke2009-01-19
| | | | | | | | Due to a wrong upper range in the time hierarchy initialisation loop, only maps on the coarsest refinement level were initialised. This caused an assertion failure when recovering multiple refinement levels which weren't aligned.
