* CarpetIOHDF5: make sure metadata matches old codeRoland Haas2011-12-14
| | | | | * add some attributes to metadata to match what the old code wrote * only tag object names with components of there are more than one
* CarpetIOHDF5: turn on 3d output in OutputSlice.ccRoland Haas2011-12-14
| | | | | | | | Register new-style output code as an IO method with IOUtil for 3d output. The new code is not quite as capable as the old code, since it does not include Ian Hinder's indexing facility and so far outputs all data on the root processor. It does support the new-style output_symmetry_points etc. options however.
* 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.
* CarpetIOHDF5: Improve handling termination checkpointsErik Schnetter2011-12-14
| | | | | When checkpoints of initial data are disabled, but termination checkpoints are enabled, then do checkpoint the initial data.

* 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: abort after I/O errors if requested by the userThomas Radke2007-04-18
| | | | | | | | | | | | By setting the new steerable boolean parameter IO::abort_on_io_errors to true in a parfile, the user can now tell the simulation to abort in case of any I/O errors while writing HDF5 output/checkpoint files. The default is to only warn about such errors and continue the simulation. This patch requires an up-to-date CVS version of thorn CactusBase/IOUtil from which the parameter IO::abort_on_io_errors is inherited. darcs-hash:20070418155052-776a0-554152ad445c5215daac96e8fa2b55f06318d0c1.gz
