* 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

* 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: 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: 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
