* CarpetIO*: New parameter CarpetIO*::out_group_separatorErik Schnetter2013-05-26
| | | | out_group_separator chooses the string by which thorn name and group name are separated in file names. The default is "::" for backward compatibility. This parameter only affects output where CarpetIO*::one_file_per_group is set; otherwise, the thorn name does not appear in the file name.
* CarpetIOHDF5: add option checkpoint_every_divisorRoland Haas2012-09-11
| | | | | | to checkpoint when cctk_iteration % checkpoint_every_divisor == 0 rather than at whenever checkpoint_every iterations have passed since the last checkpoint
* CarpetIOHDF5: New parameter skip_recover_variablesErik Schnetter2011-12-14
| | | | | Introduce a new parameter skip_recover_variables that skips recovery on a set of variables.
* CarpetIOHDF5: make sliced 3D output depend on out3D_XXXRoland Haas2011-12-14
| | | | rather than always ocuring together with the old-style 3D output.
* CarpetIOHDF5: add option to not output the buffer zonesRoland Haas2011-12-14
| | | | | | | This is implemented by re-computing the allactive bboxset that dh::regrid computes and outputting only the part of each component that intersects allactive. This changes the number of components since the intersection might be non-rectangular-box.
* 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: workaround for excessive HDF5-internal memory requirements ↵tradke2007-10-19
| | | | | | | | | | | | | | | | | | | | | | | during recovery Various people had reported problems of running out of memory when recovering from multiple chunked checkpoint files. It turned out that the HDF5 library itself requires a considerable amount of memory for each opened HDF5 file. When all chunked files of a checkpoint are opened at the same time during recovery (which is the default) this may cause the simulation to abort with an 'out of memory' error in extreme cases. This patch introduces a new steerable boolean parameter IOHDF5::open_one_input_file_at_a_time which, if set to "yes", will tell the recovery code to open/read/close chunked files one after another for each refinement level, thus avoiding excessive HDF5-internal memory requirements due to multiple open files. The default behaviour is (as before) to keep all input files open until all refinement levels are recovered. darcs-hash:20071019091424-3fd61-834471be8da361b235d0a4cbf3d6f16ae0b653f0.gz

* CarpetIOHDF5: add option to output one file per grouptradke2007-04-30
| | | | | | | | A new steerable boolean parameter IOHDF5::out_one_file_per_group was added which - if set to "true" - will cause Cactus to output all variables of a group into a single HDF5 file (useful to reduce the total number of output files). darcs-hash:20070430162902-3fd61-f8c3e4cd641c40e8afe859933e611cda50c52efe.gz
* 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
* CarpetIOHDF5: support automatic gzip dataset compressionThomas Radke2006-11-17
| | | | | | | | | With the new steerable integer parameter IOHDF5::compression_level users can now request gzip dataset compression while writing HDF5 files: levels from 1-9 specify a specific compression rate, 0 (which is the default) disables dataset compression. darcs-hash:20061117115153-776a0-7aaead5d2a0216841a27e091fddb9b6c4f40eed4.gz

* CarpetIOHDF5: remove deprecated I/O parametersThomas Radke2006-02-06
| | | | | | | | | | | This patch finally closes the long-standing issue of keeping both old and new CarpetIOHDF5 parameters around. Now the old parameters have been removed, only the new ones can be used further on. If you still have old-style parameter files, you must convert them now. The perl script CarpetIOHDF5/srcutil/SubstituteDeprecatedParameters.pl does that for you automatically. darcs-hash:20060206184519-776a0-29d9d612e011dda4bf2b6054cee73546beae373a.gz
* CarpetIOHDF5: implement parallel I/OThomas Radke2005-06-24
| | | | | | | | | | | | | | Like CactusPUGHIO/IOHDF5, CarpetIOHDF5 now also provides parallel I/O for data and checkpointing/recovery. The I/O mode is set via IOUtils' parameters IO::out_mode and IO::out_unchunked, with parallel output to chunked files (one per processor) being the default. The recovery and filereader interface can read any type of CarpetIOHDF5 data files transparently - regardless of how it was created (serial/parallel, or on a different number of processors). See the updated thorn documentation for details. darcs-hash:20050624123924-776a0-5639aee9677f0362fc94c80c534b47fd1b07ae74.gz
* CarpetIOHDF5: bugfix for checkpoint/recoveryThomas Radke2005-04-12
| | | | | | | | | | | | | | | | | | | | | | | CarpetIOHDF5 used to output unchunked data only, ie. all ghostzones and boundary zones were cut off from the bboxes to be output. This caused problems after recovery: uninitialized ghostzones led to wrong results. The obvious solution, calling CCTK_SyncGroup() for all groups after recovery, was also problematic because that (1) synchronised only the current timelevel and (2) boundary prolongation was done in a scheduling order different to the regular order used during checkpointing. The solution implemented now by this patch is to write checkpoint files always in chunked mode (which includes all ghostzones and boundary zones). This also makes synchronisation of all groups after recovery unnecessary. Regular HDF5 output files can also be written in chunked mode but the default (still) is unchunked. A new boolean parameter IOHDF5::out_unchunked (with default value "yes") was introduced to toggle this option. Note that this parameter has the same meaning as IO::out_unchunked but an opposite default value. This is the only reason why IOHDF5::out_unchunked was introduced. darcs-hash:20050412161430-776a0-d5efd21ecdbe41ad9a804014b816acad0cd71b2c.gz

* CarpetIOHDF5: deprecate all parameters with '3D' in their namestradke2004-12-03
| | | | | | | | | | | | | | | | | | | | | CarpetIOHDF5 does output for grid variables of any dimensions, not only 3D. Therefore parameters with '3D' in their names have been marked deprecated now and should not be used anymore. They are still valid though but you will get a level-1 warning if you still use them. At some point in the future those deprecated parameters will be removed. So you should eventually fix your parameter files to substitute their occurances by their newly introduced counterparts (parameters of the same name but without the '3D'). CarpetIOHDF5/src/util/ contains a small perl script which can be applied to parfiles to automatically substitute old parameter names: ~/cactus/arrangements/Carpet/CarpetIOHDF5/src/util> ./SubstituteDeprecatedParameters.pl This perl script automatically substitutes deprecated parameter names in a parfile.
