* Carpet: Add "balanced" load balancing mechanismhgErik Schnetter2012-09-10
| | | | Add new load balancing mechanism "balanced".
* Carpet: add parameter to ignore variables during Requirements checkRoland Haas2012-09-05
| | | | | | all variables and groups listed in carpet::ignore_these_variables are ignored by the requirements check, ie they are always assumed to be valid and never set.
* Carpet: Check schedule reads/writes statements at run timeErik Schnetter2012-08-30

* Carpet: make parameters steerableRoland Haas2012-06-02
|
* Carpet: change defaults of periodic_[xyz] to "yes" to match PUGHRoland Haas2012-08-02
| | | | | If any of the periodicity parameter are set to "yes" in a parameter file or checkpoint, Carpet will still abort.
* Carpet: check ghost size against restrion operator orderRoland Haas2012-06-04
| | | | if use_higher_order_restriction = yes
* Carpet…: Rename buffer2 to overlap zones; correct implementation in dhErik Schnetter2012-05-01
| | | | | | Rename buffer2 zones to overlap zones. Complete implementing overlap zones in the dh class.

* Add parameter sync_barriers to insert an MPI barrier before every syncIan Hinder2012-04-28
| | | | This causes each process to wait for all the others to reach this point in the execution. This will happen anyway (for most of the processes) during the sync, and adding this barrier means that this time is not included in the sync timer. Also add a new timer to time this barrier.

* Support accelerator data transferErik Schnetter2012-02-02
| | | | | | | | | | | | | | | | | | | This patch provides a function interface for accelerator (GPU) devices to be called at certain points when Carpet traverses the schedule tree. This can be used to copy data between the host (CPU) and the device (GPU) as it is needed. --- Carpet/Carpet/interface.ccl | 28 ++++++++++++++++++++++++++++ Carpet/Carpet/param.ccl | 6 ++++++ Carpet/Carpet/src/CallFunction.cc | 12 ++++++++++++ Carpet/Carpet/src/Comm.cc | 8 ++++++++ Carpet/Carpet/src/Cycle.cc | 4 ++++ Carpet/Carpet/src/Evolve.cc | 2 ++ Carpet/Carpet/src/Initialise.cc | 2 ++ Carpet/Carpet/src/Requirements.cc | 34 ++++++++++++++++++++++------------ Carpet/Carpet/src/variables.cc | 3 +++ Carpet/Carpet/src/variables.hh | 3 +++ 10 files changed, 90 insertions(+), 12 deletions(-)
* Carpet: Recursive load balancing: Correct some errorsErik Schnetter2012-01-11

* Carpet: Finish implementing new "recursive" load balancing mechanismErik Schnetter2011-11-14

* Introduce dummy Carpet::poison_value parameterIan Hinder2011-10-19
| | | | | | | | This parameter was removed in the past and is not used in current Carpet. However, to stop old parameter files from breaking, we reintroduce it. There is a warning in the param.ccl file that the parameter is unused, but no warning at runtime. This is not a big problem since poison is only used for debugging.
* Carpet: New parameter to set granularity for domain decompositionErik Schnetter2011-08-10
| | | | | | Add new parameters Carpet::granularity and Carpet::granularity_boundary to choose a certain granularity for the process decomposition.
* Add timer tree output and associated parametersIan Hinder2011-06-01
| | | | | | | | | | | | | | New parameters output_initialise_timer_tree and output_timer_tree_every control output of a new "timer tree diagram" to standard output for the Initialise and Evolve timer trees respectively. These diagrams indicate: 1. the value of each timer; 2. the percentage of the given tree taken by each timer; 3. which timers are contained in which other timers; 4. any untimed code for any timer which takes more than 1% of the tree time.
* Make Carpet timers hierarchicalIan Hinder2011-06-02
| | | | | | | | | | | | | | This commit modifies the timer infrastructure in Carpet to generate a tree of timers where the hierarchy reflects the call-graph of the program. This makes it much easier to interpret the timer output than with the previous flat structure, where it was not possible to see which timers "contained" which others. More implementation details are given at the top of TimerNode.hh. Note that the Timer source and header files have been renamed as CactusTimer and a new Timer file and object has been created. This is because the Timer object now only provides a wrapper around the Cactus timer mechanism which was contained in the old Timer object.
* Carpet: Add improved "recursive" load balancing scheme, part 2Erik Schnetter2011-05-01
| | | | New parameter value "recursive" for Carpet::processor_topology.
* Carpet: Allow disabling domain decompositionErik Schnetter2011-04-17

* 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.
* Carpet: Allow different numbers of ghost zones on different levelsErik Schnetter2009-12-02
| | | | | Allow different numbers of ghost zones and different spatial prolongation orders on different refinement levels.
* Carpet: Add parameter no_split_directionErik Schnetter2009-11-10
| | | | | Add new parameter no_split_direction that ensures that a domain is not split (distributed onto several processes) in a certain direction.
* Import CarpetErik Schnetter2009-09-03

* Carpet: Add new modes "global_early" and "global_late"Erik Schnetter2008-07-11
| | | | | | Add new modes meta_early, meta_late, global_early, and global_late, which execute like meta mode or global mode, but execut either as early or as late as possible in the schedule.
* Carpet: Allow higher order spatial interpolationErik Schnetter2008-04-25
|
* Carpet: Add new parameter Carpet::refine_timestepErik Schnetter2008-03-01
| | | | | | | Add a new parameter Carpet::refine_timestep which automatically adjusts the time step size according to the give spatial and temporal refinement factors, so that the specified CFL factor Time::dtfac is satisfied on all refinement levels.
* Add new parameter Carpet::grid_coordinates_filenameErik Schnetter2008-02-29
| | | | | | | | Add a new parameter Carpet::grid_coordinates_filename which specifies a file name to which the grid structure is output after regridding. This is similar to the existing parameter Carpet::grid_structure_filename, except that the output is in terms of coordinates, which is easier to interpret.
* Carpet: Add parameters limiting the maximum core and memory sizeErik Schnetter2008-02-19
| | | | | | | | Add parameters max_core_size_MB and max_memory_size_MB, limiting the maximum size of core files and the maximum amount of allocated memory. The limits are set via setrlimit during startup. darcs-hash:20080219051040-dae7b-1f11b6cf700d133adf09957ab7e80256c85eade1.gz
* Carpet: Use thorn InitBase to manage initial data setupErik Schnetter2007-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | Thorn InitBase specifies how initial data should be calculated. There can be three possibilities: init_some_levels: Set up at least one time level; other time levels are scratch space init_single_level: Set up exactly one time level; other time levels are not acessed init_all_levels: Set up all active time levels Carpet checks this parameter and ensures that this setting is consistent with Carpet's parameters init_each_timelevel init_fill_timelevels init_3_timelevels The new parameter init_fill_timelevels copies the current time level into all past time levels, very similar to what MoL::initial_data_is_crap does. darcs-hash:20070706122545-dae7b-57ccca2954b1bd7ad98771e689c6c5b569c238cc.gz

* Carpet: Determine time integrator substeps automaticallyErik Schnetter2007-05-24
| | | | | | | | By default, call MoLNumIntegratorSubsteps to find out how many time integrator substeps there are. Can be overridden by setting Carpet::num_integrator_substeps. darcs-hash:20070524214138-dae7b-4b8eb8aca92f62461460f937bbb3feb54b06f455.gz

* Carpet: Allow fewer or more buffer zones to be specifiedErik Schnetter2007-05-02
| | | | | | | | Introduce a parameter Carpet::additional_buffer_zones, which allows using more or fewer buffer zones than there would be when calculated from the ghost zones. darcs-hash:20070502141602-dae7b-c7209f710a3186aee6dfea8700312d04562b0928.gz
* Carpet: Various setup changesErik Schnetter2007-04-19
| | | | | | | | | | Make buffer zones always inner buffer zones (but update CarpetRegrid2 to increase the domain automatically). Calculate the base grids before creating the gh. Use information about the outer boundaries for this. darcs-hash:20070419015830-dae7b-da010f022aa948a955b818256a0c0c4e68ba42ce.gz
* 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
