| * Re-organise some refluxing internalsErik Schnetter2012-09-11
| | | | | | | | | | | | | | | | | | | | | | Re-organise some of the internal details of refluxing. Refluxing requires restricting fluxes from fine to coarse grids. Previously, Carpet would internally store bounding boxes that were offset by 1/2 grid point, and adjust (correct) these boxes in various places in a rather ad-hoc manner. This is now cleaned up. Remove the (unused) "accumulate" operator, and the (unused) "accumulate" prolongation type.

* Improve named barriersErik Schnetter2011-12-14
| | | | | | | | | Introduce dist::barrier as low-level implementation of a named barrier. Use it in Carpet::NamedBarrier. Use the above in almost all barrier calls.

* CarpetLib: Improve bboxlib algorithmsErik Schnetter2011-12-14
| | | | | | | Modify the algorithm used to insert a new bbox into an existing bboxset. This reduces the computational complexity of this operation from O(n^2) to O(n), where n is the number of elements in the bboxset. This has the potential to speed up regridding significantly.

* CarpetLib: Correct component and process ids while regriddingErik Schnetter2011-12-14
| | | | | | | During regridding, there are two sets of component indices and process numbers, namely those of the old and of the new grid structure. Previously, Carpet would erroneously always use those of the new grid structure; this fails when the number of components changes.
* CarpetLib: Correct communication schedule for regridding prolongationErik Schnetter2011-12-14
| | | | | Correct communication schedule for regridding prolongation for cell-centred mesh refinement.
* Adapt Carpet to hierarchical timersIan Hinder2011-12-14
| | | | | | | | Specifically, remove any hierarchy information that has been added to the name of timers, as well as any code for creating timers dynamically, as these are now unnecessary. Additionally, time some previously-untimed parts of the code and make timer names in some places more consistent.

* Select 2nd order cc-eno for 3rd order interpolation since stencil radius is ↵Christian Reisswig2011-12-14
| | | | | | | | | | larger. This is consistent with vertex-centered eno. The trouble is that Carpet derives the stencil radius from the interpolation order imposing Lagrange interpolation. I also commented out the code that checks whether we have to switch down to first order. According to Shu, this is not necessary! This way interpolation runs faster.

* CarpetLib: Introduce gdata::allocated_memory_shapeErik Schnetter2011-12-14
| | | | | | Introduce a function gdata::allocated_memory_shape that determines from a given grid size how many grid points should be allocated. This allows adding padding to grid sizes, e.g. to improve cache performance. Use this function when checking grid sizes.
