* CarpetLib: Do not check invariant of bboxset classErik Schnetter2005-03-21
| | | | | | | | | Checking the invariant of the bboxset class is probably O(N^3) in the number of bboxes, possibly worse. It is a very slow operation when there are many components in a simulation, especially with AMR, and possibly also when running on many processors. darcs-hash:20050321020814-891bb-c5eb1cde6f3ac064e39a362b19bd20e15d03bc24.gz

* Carpet/CarpetLib: minimise the number of outstanding communication requeststradke2005-03-11
| | | | | | | | | | | | | | | | | | | | | | | This patch greatly reduces the number of outstanding MPI_Isend/MPI_Irecv communication requests by moving the loop over comm_states (recv,send,wait) from the outermost to the innermost. This resolves problems with certain MPI implementations (specifically LAM, MPICH-NCSA, and Mvapich over Infiniband) which potentially resulted in some communication buffer overflow and caused the Cactus application to abort or hang forever. Preliminary benchmarks with BSSN_MoL show that the patch does not have a negative impact on myrinet clusters (measured to 64 processors). It even improves the Carpet performance on GigE clusters (measured up to 16 processors). The order of the communication loops is controlled by the boolean parameter CarpetRegrid::minimise_outstanding_communications which defaults to "no" (preserving the old behaviour). darcs-hash:20050311160040-3fd61-04d40ac79ef218252f9364a8d18796e9b270d295.gz

* CarpetAdaptiveRegrid: Fix checking the child level for errorsIan Hawke2005-03-04
| | | | | | | | | Firstly only check the errors of a child level if a grandchild level exists. Secondly take the refinement factor into account when calculating where this error should be placed! darcs-hash:20050304134516-58c7f-484d0c7d61a089b4eb7f294c427c76bb529d8dde.gz

* Carpet: Add new flag Carpet::constant_load_per_processorErik Schnetter2005-03-07
| | | | | | | | Add a new flag Carpet::constant_load_per_processor which takes the specified grid size and multiplies it by the number of processors. When running benchmarks, this keeps the local load constant. darcs-hash:20050307165844-891bb-7b4c36a5e3bb152086d2eb240a898cb2ac5a3122.gz

* CarpetAdaptiveRegrid: Documentationih2005-02-25
| | | | | | | | | | | | | Add some documentation for the AMR, and also an example parameter file (shock tube, 6 levels). Note that my last message about parallel AMR was incorrect; the difference between the 1 and 2 processor runs was entirely due to a bug in Whisky, not in the AMR. Once that was fixed, the results now agree to output precision. Therefore I pronounce parallel AMR "working". darcs-hash:20050225194759-0ff1f-967f0360b73244634d422198c9446f812302c916.gz

Note that at present whilst it runs and gives reasonable answers you do _not_ get the same answers as you would on 1 proc. This is a bug, as yet unfound. But, there probably are lots of other bugs in this code still to be found... darcs-hash:20050224223702-0ff1f-f766381f5309c747ea438dbd10976a99c86abd48.gz
