* CarpetLib: Add new datatype region_tErik Schnetter2007-01-12
| | | | | | | | | | | | | | | | | | | | | | | The new datatype region_t combines an extent (a bbox), an outer boundary descriptor, a refinement descriptor, and a processor number: struct region_t { ibbox extent; // extent b2vect outer_boundaries; // outer boundaries b2vect refinement_boundaries; // refinement boundaries int map; // map to which this // region belongs int processor; // processor number }; These quantities are often used together, and combining them into a single datatype simplifies the code significantly. Adapt gh, dh, etc. to use this new datatype. This is a major API change. darcs-hash:20070112204130-dae7b-92cad546187b0fe499e8cfc38b2e26614a4f608c.gz
* CarpetLib: Make many MPI experiments configurableErik Schnetter2006-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new parameters: BOOLEAN interleave_communications: Try to interleave communications with each other; each processor begins to communicate with its 'right neighbour' in rank, instead of with the root processor BOOLEAN vary_tags: Use different tags for each communication BOOLEAN barrier_between_stages: Add a barrier between the communication stages (slows down, but may make timing numbers easier to interpret) BOOLEAN combine_sends: Send data together and in order of processor ranks BOOLEAN reduce_mpi_waitall: Call MPI_Waitall only for requests that are not null BOOLEAN use_mpi_send: Use MPI_Send instead of MPI_Isend BOOLEAN use_mpi_ssend: Use MPI_Ssend instead of MPI_Isend darcs-hash:20061206165333-dae7b-8ba40bd19fb1733336e60cb7e6bfa0ebfe0d546d.gz
* CarpetLib: Add placeholders for "const" and "pure" attributes to vect<T>Erik Schnetter2006-07-31
| | | | | | | | | Add __attribute__((const)) and __attribute__((pure)) to vect<T> functions where appropriate. These attributes are not active, because it is not clear that this really improves performance, and errors could lead to wrong code. darcs-hash:20060731152218-dae7b-20c523f60890b2ad611157764e0b993bfb185c8d.gz

* CarpetLib: Use better algorithm to combine bboxes in bboxset's normalize()Erik Schnetter2006-12-05
| | | | | | | | | The new algorithm always finds the same canonical configuration of bboxes, independent of how the bboxset is split into bboxes. There is no guarantee that the new representation uses the minimum number of bboxes, since that would be too difficult. darcs-hash:20061205211342-dae7b-2eee2ac16cea06b3ee4fc623deb086d380d5ed37.gz

* CarpetLib: Split recompose functions into regrid and recomposeErik Schnetter2006-09-04
| | | | | | | | | | | | | | | Split recompose functions into two stages, regrid and recompose. The first stage, regrid, changes the grid structure in the gh and dh classes. The second stage, recompose, changes the values of the actual grid functions, i.e., changes the gf<T> and data<T> objects. The second stage has to be called individually for every refinement level. This is necessary since the boundary conditions need to be applied after recomposing one refinement level, before the next fine refinement level can be recomposed. darcs-hash:20060904230433-dae7b-3ba1982460f57b34da11a6fbb6b4b524dc5b348f.gz

* [CarpetLib] add option to omit Fortran 90 files by adding -DOMIT_F90 to ↵Jonathan Thornburg2006-08-29
| | | | | | | | | | | | | | | | | | | | | | | | compiler flags Carpet is _almost_ entirely written in C, C++, and Fortran 77, but there are a few Fortran 90 files in CarpetLib defining the ENO and WENO prolongation operators. This patch allows Carpet to be compiled without a Fortran 90 compiler if these (ENO/WENO) operators are not needed, by defining the C preprocessor symbol OMIT_F90. For example, you could do this by putting CFLAGS=-DOMIT_F90 CXXFLAGS=-DOMIT_F90 F77FLAGS=-DOMIT_F90 F90FLAGS=-DOMIT_F90 in a ~/.cactus/config file. I emphasize that in the default case, where OMIT_F90 is not defined, this patch is a no-op: the ENO and WENO prolongation operators are still defined, a Fortran 90 compiler is still needed to compile CarpetLib, you still pass go, you still collect $200. :) This patch only changes the behavior of Carpet in the non-default case where OMIT_F90 is defined. darcs-hash:20060829170502-b0a3f-0d423f190bd7388faa9e1a6e0a980694b044516b.gz
* CarpetLib: fix prolongate_3d_real8_minmod.F77 to fortran77 standardsbaiotti2006-08-09
| | | | | | The fortran77 standards require that a "function" must be ended by "end" and not by "end function". The non-standard syntax is accepted by several compilers, but not by the Portland compiler. darcs-hash:20060809133700-d5812-14616fe5ee7f5e75087f09ae7cc9d83acd27bd42.gz

* CarpetLib: Poison newly allocated memory if desiredErik Schnetter2006-07-31
| | | | | | | | | Poison newly allocated memory if desired. This is potentially more thorough that Carpet's poisoning, since it is applied to all allocated memory. It is not applied after time level cycling, though, so it cannot replace Carpet's poisoning. darcs-hash:20060731152325-dae7b-d039ee958161690c9430e70a8051d400273b819e.gz
* CarpetLib: Use double instead of size_t for memory statisticsErik Schnetter2006-07-31
| | | | | | | | | Use double instead of size_t for memory statistics. size_t works fine for keeping statistics on a single processor, but there can be overflow on multiple processors. double may be inexact, but will not overflow. darcs-hash:20060731152039-dae7b-51a07bfa276c18a59b400a4aef09ab3f2cfc1490.gz

| | | | | | | | | | | | | | Add a parameter "omit_prolongation_points_when_restricting" that controls whether to restrict to points that are used for boundary prolongation. The default is "no", restoring Carpet's behaviour from before the patch "CarpetLib: Do not restrict to points that are used for boundary prolongation". When set to yes, then there is still a logic error in the code on multiple processors, leading to different restriction regions on different numbers of processors. darcs-hash:20060503235940-dae7b-4c124e68e4c2519c0f97d416e0a7fa3489c1441d.gz
