* CarpetLib: Set number of OpenMP threads via an external function callErik Schnetter2008-01-14
| | | | | | | Set the number of OpenMP threads via an external function call instead of via a CarpetLib parameter. darcs-hash:20080114150439-dae7b-a6a6a629162ca195411852823e1ece0a2071d771.gz
* CarpetLib: Add support for OpenMPErik Schnetter2007-08-21
| | | | | | | | | | | Add #pragma omp statements for loops in reduction and prolongation operators. Change loop control variables to signed types. Add functions to determine the number of active threads. Add a parameter to set the number of threads if desired. darcs-hash:20070821185237-dae7b-56827b72a69b5fa1b3d1316379a0f155696b4cb2.gz
* CarpetLib: Remove commented out code for complex variablesErik Schnetter2007-02-04
| | | | | | | | | CarpetLib contained special code that used std::complex instead of Cactus's CCTK_COMPLEX for complex variables. A very similar feature is now supposed to go into the flesh, and hence this (unused) code is being removed. darcs-hash:20070204172854-dae7b-af7b7aca42988195846220dd7f45827549f5caf9.gz

* Carpet*: generalise the comm_state class for collective buffer communicationsThomas Radke2005-08-15
| | | | | | | | | CarpetLib's comm_state class (actually, it's still just a struct) has been extended to handle collective buffer communications for all possible C datatypes at the same time. This makes it unnecessary for the higher-level communication routines to loop over each individual datatype separately. darcs-hash:20050815150023-776a0-dddc1aca7ccaebae872f9f451b2c3595cd951fed.gz

* CarpetLib: Change checking of processor number in data classErik Schnetter2004-12-30
| | | | | | | | | | | | | Remove functions gdata::lives_on_this_processor() and gdata::this_processor_is(proc). Introduce dist::rank() and dist::size() instead. Re-introduce assert statement in data::proc(). Move declaration and definition of assignment operator near the constructor and destructor. darcs-hash:20041230191026-891bb-90eeb1be4c04753c165e13e7c1e65f06847180ca.gz

* Many changes that accumulated while Cactus and Carpet diverged.schnetter2003-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many changes that accumulated while Cactus and Carpet diverged. Add processor splitting mechanism "along-dir" that splits along a specified direction. Rename group PostRestrict to bin POSTRESTRICT. Prolongate initial data only when desired. This saves much time. Sorry, Ian. Fix bug in time level cycling of grid arrays. (Note: grid arrays should not have time levels.) Fix time_t bug on IRIX. Make sure that there is no integer overflow when there are many refinement levels. Always put parentheses around (maxreflevelfact/reflevelfact). Fix typo in Carpet verbose output. Add debug output in processor splitting. Communicate in three stages: Irecv, (work), Isend, Wait. This might be more efficient. Much more, potentially. Fix bug in processor layout of grid arrays. Sorry, Ian. Make the interpolator interpolate between time levels. Untested. Fix bug in processor communication in interpolator. Sorry, Ian. Rewrite prolongation operators to make them twice as fast. There you are, Ian. Move prolongation operator kind handling from data to gdata. Add official hyperslabbing interfaces to CarpetSlab. Adapt to new cGH * handling. darcs-hash:20031105151837-07bb3-758a87ff0355dba053269df4b7d7d79bea018669.gz

| | | | | | | | | | | | | Removed the "dimgeneric_*" data types from CarpetLib. They were never really used anyway. Changed "th" into "th<D>". Renamed "generic_*" to "g*". Propagated these changes to all other places. darcs-hash:20030103144936-07bb3-c4d74d2d94a56a898f9bb735666eefc01e2610e2.gz

* Removed user choice of C++ template instantiation model. In myschnetter2002-05-05
| | | | | | | | | | | | | | | | | Removed user choice of C++ template instantiation model. In my experience, only one model works, namely explicit template instantiaion. No need to pretend that the other things work with Cactus. (Don't complain to me -- I also think it's a shame that something that calls itself "compiler" isn't able to do this automatically. Many other compilers for many other languages do this kind of thing without even mentioning it. So there's either something fundamentally wrong with the C++ standard, or with the C++ compiler writers, or with the perceived wishlists of C++ users. And I would bet an arm and a leg that it's not the second of these.) darcs-hash:20020505201656-07bb3-a1b8dfc5587d59c718ad25ce89d0c8973c2b3e6f.gz
