* Carpet: Add "balanced" load balancing mechanismhgErik Schnetter2012-09-10
| | | | Add new load balancing mechanism "balanced".
* Carpet: Requirements: Correct function typesErik Schnetter2012-09-10
| | | | Correct types of Carpet_Requirements_CheckReads and Carpet_Requirements_NotifyWrites
* Carpet: insert routines into Boundary group to capture boundary updateRoland Haas2012-09-07
| | | | reads and writes
* Carpet: add routines to record READS/WRITES at runtimeRoland Haas2012-09-06
| | | | | | THe external interface seems ok, but the internals will be rewritten to avoid repeated string parsing, memory allocation and internal std::map manipulations.
* Carpet: add aliased routines to obtain map, timelevelRoland Haas2012-09-07
|
* Carpet: Do not count ghost zones when calculating speedErik Schnetter2012-04-04
| | | | When calculating the speed of a simulation, ignore ghost zones. Use two counters, one including the outer boundaries, the other excluding it.
* Inform the Accelerator thorn that past timelevels have been filled on the hostIan Hinder2012-02-13
|
* Carpet: Make host/process association publicly availableErik Schnetter2012-02-02
| | | | | | | Determine and store host/process association. Provide aliased function API to query this. Improve performance of multi-model API.
* 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(-)

* Combine CarpetLib's INSTANTIATE and Carpet's TYPECASE mechanism into aErik Schnetter2010-02-13
| | | | | | single mechanism provided by CarpetLib. Use this mechanism everywhere.
* Carpet: Add new aliased function GetLocalComponentsErik Schnetter2009-11-08
| | | | | | | Add a new aliased function GetLocalComponents which returns the number of process-local components. Some code can handle only one component per MPI process, and GetLocalComponents can be used to test this at run time.
* Carpet: Implement padding from grid variablesErik Schnetter2009-09-21
| | | | | | | | | | | | Ignore-this: ac4962293cd7c0313a0f17f3ccd59e96 Set the cGH and cGroupDynamicData entries correctly if padding is used. cctk_lsh then contains the number of grid points that have been allocated, cctk_lssh contains the number of grid points that should be used. cctk_lssh is also used for staggered grid functions, although this kind of staggering is not supported by Carpet.

* Introduce a tree data structure to speed up domain decompositionErik Schnetter2008-06-20
| | | | | | | | | Introduce a tree data structure "fulltree", which decomposes a single, rectangular region into a tree of non-overlapping, rectangular sub-regions. Move the processor decomposition from the regridding thorns into Carpet. Create such trees during processor decomposition. Store these trees with the grid hierarchy.
* Implement schedule wrappersErik Schnetter2008-03-01
| | | | | | | Schedule wrappers are routines that can be registered with Carpet. They will be called before and after any scheduled routine is called. This allows custom debugging and profiling routines, such as e.g. single-stepping through the schedule.
* Carpet: Use MultiPatch_ConvertFromPhysicalBoundary, if availableErik Schnetter2008-02-19
| | | | | | | Use MultiPatch_ConvertFromPhysicalBoundary instead of CoordBase's ConvertFromPhysicalBoundary, if it is available. darcs-hash:20080219172824-dae7b-a63ad0a3897917f703c5c65a0a05beb4bf690b24.gz

* Carpet: Record time spent in I/O and in communicationErik Schnetter2007-10-03
| | | | | | | | Improve Carpet's timing mechanism to record also the time spent in I/O and in communication. Also count the number of files written, messages sent, and bytes transferred. darcs-hash:20071003194325-dae7b-b7a908e8c49aa674de44d67c4a4c81844ca123ca.gz

* Carpet: Add aliased function GetCoordRangeErik Schnetter2007-06-14
| | | | | | | | GetCoordRange returns the lower and upper coordinates, the grid spacing, and the number of grid points for a given refinement level on a given patch. darcs-hash:20070614004919-dae7b-29bbe29bfb33715fefe7ac192f0d920de8159b49.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: 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: Improve timing statisticsErik Schnetter2007-02-27
| | | | | | | | Calculate both processor-local and total number of grid points updates. Store grid point updates in a 1d grid array, so that statistics (sum, average) can be easily output. darcs-hash:20070227202839-dae7b-74b51ea240995de247a6eed5d973b0a4f3d84b13.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: Calculate processor distribution for all maps at onceErik Schnetter2006-08-04
| | | | | | | Calculate processor distribution for all maps at once instead of for each map separately. This leads to more efficient distributions. darcs-hash:20060804133816-dae7b-b16a915db7764714debb4523b1f70b586b5d8719.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
* Carpet: Pass MPI communicators as pointers instead of intsErik Schnetter2005-08-26
| | | | | | | | | Pass MPI communicators as pointers instead of ints because they may not be implemented as ints. Use MPI_COMM_NULL instead of -1 as illegal communicator. darcs-hash:20050826144511-891bb-324a5d22efcbbd53cac35899e30559b06cfdfdb6.gz
* Carpet: Allow multi-model simulationsErik Schnetter2005-08-25
| | | | | | | | | | Split MPI_COMM_WORLD according to a new parameter Carpet::model into different sets, and evolve these sets independently. Add aliased functions to query the MPI communicators for this simulation and for all models. darcs-hash:20050825084739-891bb-7f102b46ec495f884be5197eaf077eef93f89dac.gz
* Carpet: Add support to get the domain specification from the multipatch thornErik Schnetter2005-07-05
| | | | | | | | | Introduce aliased functions MultiPatch_GetBoundarySpecification and Multipatch_GetDomainSpecification which can be provided by a multipatch thorn. This will make it possible to have different grid setups on different patches. darcs-hash:20050705103636-891bb-4f03733ed93abf1d70efa1c64e13dc4066a91cf1.gz
* global: Change the way in which the grid hierarchy is storedErik Schnetter2005-02-01
| | | | | | | | | | | | | | | | | | | | Change the way in which the grid hierarchy is stored. The new hierarchy is map mglevel reflevel component timelevel i.e., mglevel moved from the bottom to almost the top. This is because mglevel used to be a true multigrid level, but is now meant to be a convergence level. Do not allocate all storage all the time. Allow storage to be switched on an off per refinement level (and for a single mglevel, which prompted the change above). Handle storage management with CCTK_{In,De}creaseGroupStorage instead of CCTK_{En,Dis}ableGroupStorage. darcs-hash:20050201225827-891bb-eae3b6bd092ae8d6b5e49be84c6f09f0e882933e.gz
* global: Turn CarpetLib templates into classesErik Schnetter2005-01-01
| | | | | | | | | | | | | | | | | | | Turn most of the templates in CarpetLib, which used to have the form template<int D> class XXX into classes, i.e., into something like class XXX by setting D to the new global integer constant dim, which in turn is set to 3. The templates gf and data, which used to be of the form template<typename T, int D> class XXX are now of the form template<typename T> class XXX The templates vect, bbox, and bboxset remain templates. This change simplifies the code somewhat. darcs-hash:20050101182234-891bb-c3063528841f0d078b12cc506309ea27d8ce730d.gz
