* Provide LoopControl macros.schnetter2009-11-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These generalise the LoopControl thorn of Carpet, and introduce a generic looping mechanism to Cactus. They provides a simple, straightforward implementation (without the optimisations found in Carpet's LoopControl thorn), and other thorns can provide various optimisations, e.g. loop tiling or OpenMP parallelisation. The macros are defined in a new file cctk_Loop.h, automatically included from cctk.h. There are macros for 1D, 2D, 3D, and 4D loops, corresponding to Cactus' CCTK_GFINDEX* macros. Each macro comes in four variants: CCTK_LOOP3: a generic 3D loop CCTK_LOOP3_ALL: loop over all grid points of a grid function CCTK_LOOP3_INTERIOR: loop over the interior points, excluding ghost, symmetry, and boundary points CCTK_LOOP3_BOUNDARY: loop over all (outer) boundary points The header file contains a straightforward implementation via macros that expand to corresponding "for" statements. There are also macros for Fortran, but these are much less elegant since Fortran does not support block-scope local variables. In addition, Fortran requires declaring certain variables as private when OpenMP is used, which adds another complication. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4581 17b73243-c579-4c4c-a9d2-2d5706c11dac

* Add IF clauses to schedule itemsschnetter2008-04-09
| | | | | | | | | | | | | | | Schedule items in Cactus can already have WHILE clauses, which means that they are executed while a certain condition are true. This patch adds IF clauses, which means that they are executed only if a certain condition is true. The syntax is equivalent to WHILE clauses. These if clauses is different from the existing C-syntax if statements, which are only evaluated at startup and determine how the schedule is constructed. These if clauses are evaluated every time the schedule is traversed, and can skip certain schedule items. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4478 17b73243-c579-4c4c-a9d2-2d5706c11dac
* Add a new function CCTK_MaxGFDim to the flesh which returns theschnetter2008-04-07
| | | | | | | | | | | | | | | | | (maximum) dimension of all grid functions. Cactus can currently not handle the case where one uses grid arrays of dimension D while grid functions have a dimension less than D. During initialisation, Cactus sets cctk_dim to the largest dimension of all grid variables in all active thorns. This is arguably wrong; cctk_dim should be set to the (maximum) dimension of the grid functions. This patch adds a new function CCTK_MaxGFDim to the flesh which returns the (maximum) dimension of all grid functions. This function is used to set cctk_dim. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4476 17b73243-c579-4c4c-a9d2-2d5706c11dac

* This patch makes complex arithmetic in C and C++ more efficient, andschnetter2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | makes it much more convenient for C++, expecially when templates are used. The flesh functions for complex arithmetic are defined (not only declared) by including Complex.c from the header file cctk_Complex.h. They are declared "static inline", so the the compiler can inline them, but does not have to create an out-of-line copy for every source file. Complex.c is also compiled stand-alone without the "static inline" prefix, so that out-of-line copies exist as well. Add some new complex arithmetic functions, e.g. ComplexNeg to change the sign. Make some complex arithmetic functions more efficient by using algorithms from glibc. These algorithms are LGPL. They should be faster and/or more accurate than the existing implementations. For C++, define the usual arithmetic operators (+-*/ etc.) as inline functions calling the corresponding complex arithmetic functions. This makes it possible to use complex numbers in the same way as real numbers, which makes it possible to instantiate templates for both CCTK_REAL and CCTK_COMPLEX. This leads to much code reduction in Carpet. The patch also appends a type postfix to the names of math functions called in the inlined routines: 'f' for HAVE_CCTK_REAL4, nothing for HAVE_CCTK_REAL8, and 'l' for HAVE_CCTK_REAL16. This avoids compiler warnings about conversions from "double" to "float" which may lose significant bits. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4418 17b73243-c579-4c4c-a9d2-2d5706c11dac

* Add a new command line option to select the buffering mode of stdout.schnetter2006-06-23
| | | | | | | | | | | | | The option is "-b <mode>", or "-buffering=<mode>", where mode can be "no", "line", or "full". This option uses the ANSI C function call setvbuf() to select the corresponding buffering mode. The buffering mode can be selected only once in a portable programme, and it has to be selected before the first output occurs. This means that it has to be implemented in the flesh. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4329 17b73243-c579-4c4c-a9d2-2d5706c11dac
