* CarpetLib: Count number of received bytes correctly in comm_stateErik Schnetter2008-07-15
|
* CarpetLib: Add new parameter combine_recomposeErik Schnetter2008-07-15
| | | | | | | combine_recompose recomposes all grid functions at once. This increases memory usage, but combines the communications and may thus also increase the speed. The default behaviour is unchanged, recomposing all grid functions sequentially.
* Move implementation of create_mpi_datatype from CarpetInterp2 to CarpetLibErik Schnetter2008-07-15
|
* CarpetLib: Simplify gf::typed_data slightlyErik Schnetter2008-07-15
|
* CarpetLib: Correct C++ error in prolongation operatorsErik Schnetter2008-07-15
| | | | | Specify the template parameter T explicitly when calling the pointwise interpolation routine.
* CarpetLib: Export include file typeprops.hhErik Schnetter2008-07-15
|
* CarpetLib: Implement function gh::locate_positionErik Schnetter2008-07-15
| | | | | | Implement a new function gh::locate_position which finds the refinement level and component which owns a certain location. This is e.g. useful for interpolation.
* Move definition of rvect, jvect etc. from Carpet to CarpetLib.Erik Schnetter2008-07-15
| | | | Remove include file defines.hh in Carpet.
* CarpetLib: Correct error in prolongation coefficientsErik Schnetter2008-07-15
| | | | Correct the 11th order prolongation coefficients.
* 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.
* CarpetLib: Correct regridding communication scheduleErik Schnetter2008-05-20
| | | | | Handle correctly the case where the multi-patch processor decomposition changes during regridding.
* CarpetLib: Compare simulation times with relative accuracyErik Schnetter2008-05-14
|
* CarpetLib: Correct typo in commentErik Schnetter2008-04-25
|
* CarpetLib: Add higher order interpolation operatorsErik Schnetter2008-04-25
|
* CarpetLib: Improve error message when overly large bbox is createdErik Schnetter2008-04-01
|
* CarpetLib: Add a fall-back dummy timer in case no system timer is foundErik Schnetter2008-03-28
| | | This fall-back timer only counts how often it is called.
* CarpetLib: Update cycle.hErik Schnetter2008-03-27
| | | | | Update the file cycle.h from FFTW. This file defines the low-level and system-dependend timers. This update should add support for IBM compilers on PPC architectures.
* OpenMP changes:Erik Schnetter2008-03-21
| | | | | | | Use #pragma instead of _Pragma for OpenMP directives. The PGI compilers do not understand the _Pragma syntax. Use int instead of ptrdiff_t for loop variables which are parallelised via OpenMP. The PGI compilers cannot handle ptrdiff_t.
* Enhance support for multi-patch simulationsErik Schnetter2008-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | Carpet: Ensure that at most one of GetDomainSpecificatio or MultiPatch_GetDomainSpecification is defined. Allow the boundary case of having zero regions on a refinement level. CarpetLib: Allow the boundary case of having zero components on a patch, if there are still more than zero components overall. CarpetIOASCII: Loop over the components using explicit light-weight for loops instead of Carpet's looping macros. This is faster, since less state information needs to be updated. Correct an inconsistency in converting between integer indices and coordinates in multi-patch simulations. CarpetRegrid2: Take multi-patch systems into account.
* CarpetLib: Output type information in bbox error messagesErik Schnetter2008-03-19
|
* Add preprocessor macro CARPET_HAVE_BUFFER_WIDTH to carpet.hhIan Hinder2008-03-05
|
* CarpetLib: Correct memory leak in commstate classErik Schnetter2008-03-01
| | | | | | Correct a memory leak and simplify the code in the commstate class by using C++ datatypes instead of new and delete. Add many assert statements to catch potential problems.
* Move communication schedule into its own data structureErik Schnetter2008-02-29
| | | | | | | Splite the grid hierarchy and communication schedule into two separate data structures. Correct error in determining the processor owning a certain region when calculating the communication schedule.
* Use MPI_CHAR instead of MPI_BYTE for to represent a C charErik Schnetter2008-02-29

* Carpet/CarpetLib/src/prolongate_3d_real8_eno.F90baiotti2008-02-28

* CarpetLib: Output all digits in error messageErik Schnetter2008-02-25
| | | | | | | Output all digit for the times in the error message indicating that there is an extrapolation in time. darcs-hash:20080225055300-dae7b-500b168cc5b5f9c57b31c54e7ee07114062dca51.gz
* CarpetLib: Change API of ggf's cycle, flip, and fillErik Schnetter2008-02-19
| | | | | | | | | Rename cycle, flip, and fill to cycle_all, flip_all, and fill_all, respecively, in the ggf class. Remove the c ("component") argument. Instead, loop over all components. This mirror earlier changes to sync etc. darcs-hash:20080219045150-dae7b-f2198d253aac5b62d247a51155a08c3739daa720.gz
* CarpetLib: White space change in ggf.ccErik Schnetter2008-02-19
| | | | darcs-hash:20080219045115-dae7b-b098e7d4835a115ea87fc0ed656ba87f803a368b.gz
* CarpetLib: Remove some superfluous if statements in the communication scheduleErik Schnetter2008-02-19
| | | | | | | Remove some superfluous if statements when calculating the communication schedule. This re-indents a lot of code. darcs-hash:20080219044952-dae7b-61370e7eab49b5f173fa25778d6fbc1b2570f84b.gz
* CarpetLib: Simplify implementation of data<T>::allocsizeErik Schnetter2008-02-19
| | | | darcs-hash:20080219044903-dae7b-e51f39ce37e1d2b812cc996d99c81bd8468bd034.gz
* CarpetLib: Make mem<T> saferErik Schnetter2008-02-19
| | | | | | | | | | When passing in a pointer to mem<T>, also pass the size of the pointed-to memory region, so that mem<T> can check that there is enough space. Keep track of the number of allocated bytes in mempools. darcs-hash:20080219044528-dae7b-107edc6f696a35aad32ef6e58129b3281d00eb56.gz
* CarpetLib: Use vector<char> instead of new char in commstate classErik Schnetter2008-02-19
| | | | | | | | | | Use vector<char> instead of new char[] in the commstate class. This corrects a memory management error. Use .AT() instead of [] to access vector elements to catch indexing errors. darcs-hash:20080219044221-dae7b-ecd72b45833617920a33311953d5c2f00c42568c.gz
* CarpetLib: Add function memoryof to measure size of data structuresErik Schnetter2008-02-02
| | | | | | | Add an overloaded function memoryof which measures the size in bytes of CarpetLib's data structures. darcs-hash:20080202154302-dae7b-de41c79cb04617327695fae27928c05c5d431ee8.gz

* CarpetLib: Remove unoptimised fields of dh::boxes structureErik Schnetter2008-01-30
| | | | | | | | | | Remove the unoptimised and the old-style optimised fields for the communication and regridding structure from the dh::boxes structure. (Keep the new-style optimised fields.) Remove the code that sets them. Remove the old-style optimisation routines. Update the output routines. darcs-hash:20080130221033-dae7b-cd7a9b8445ba13eaf95af2b1739bf6592cebdbcf.gz
* CarpetLib: Move pseudoregion datatypes to region.hhErik Schnetter2008-01-30
| | | | | | | | | Rename the datatypes pseudoregion and sendrecv_pseudoregion to pseudoregion_t and sendrecv_pseudoregion_t, respectively. Move their declaration and definition to region.hh and region.cc, respectively. Instantiate templates for stream output. darcs-hash:20080130221653-dae7b-8eb25cacc8f7750ac470179c9575785bdb32b575.gz

* CarpetLib: Introduce new communication scheduleErik Schnetter2008-01-14
| | | | | | | | | | Store the communication schedule more efficiently: store only the non-zero parts. This saves much time when traversing the schedule. Add new communication routines which communicate not between only two individual components, but between all components. darcs-hash:20080114152229-dae7b-7b7ba51bd8b5de0a0009ea236f4a894667b0281b.gz

* CarpetLib: Add function ggf::fill, which fills all time levelsErik Schnetter2008-01-14
| | | | | | | | | Add a new function ggf::fill, which fills all time levels from the current time level. Remove the function ggf::copy, which was unused. darcs-hash:20080114151255-dae7b-469b57d0393ba0ed22590c2eabe862e02702fde7.gz

* CarpetLib: Use timing routines from FFTW libraryErik Schnetter2008-01-14
| | | | | | | | | | Use the timing routines from FFTW library. These contain platform-specific code for many different platforms. Remove parameter timestat_timer, since the timer is now chosen automatically. darcs-hash:20080114150519-dae7b-d979aa53a1470335b3ace353e862eef13670958d.gz
