* Currently Cactus sets up flags like CPPFLAGS or CFLAGS by adding e.g.knarf2013-07-09
| | | | | | | | | | | | | | | | | | | | | | | | CPP_OPENMP_FLAGS. However, later it overwrites these again by their original value in sbin/ProcessConfiguration.pl (search for FIXME). This patch implements what the 'FIXME' suggests - accepting the drawbacks that are mentioned there: that configuration settings not originating from a thorn might not be forwarded from e.g., a .cactus/config file. MPI was one of these, but this is now handled differently anyway. With this patch, we would need to be aware of these and might need to add them to @allowed_opts in the future. Without the patch however, compilation might fail for perfectly valid setups. One of these is when using openmp, setting all the corresponding *_OPENMP_FLAGS, but not setting CPPFLAGS (only CPP_OPENMP_FLAGS). In this case ProcessConfiguration.pl will set CFLAGS to the version in the config file (*without* the -openmp), but it will leave CPPFLAGS to the version *with* -openmp. This later leads to a linker error in external libraries, since compilation there uses CPPFLAGS (with openmp), but the linker doesn't (It correctly uses CFLAGS, but this doesn't have openmp flags here). git-svn-id: http://svn.cactuscode.org/flesh/trunk@5034 17b73243-c579-4c4c-a9d2-2d5706c11dac

* check that providing function name is different from aliased function namerhaas2013-06-05
| | | | | | | | | | | | | | | | | | in interface.ccl. Before f an aliased function is declared in interface.ccl with PROVIDES FUNCTION fun WITH fun LANGUAGE C Cactus went into an infinite loop when calling that function. It did so because it creates a function 'fun' (the first) itself, which then calls (fun) the second. Instead, Cactus now produces an error for above declaration. The two 'fun' must be different for this to work, and Cactus should catch this. Reported by Frank Loeffler in ticket 1376. git-svn-id: http://svn.cactuscode.org/flesh/trunk@5024 17b73243-c579-4c4c-a9d2-2d5706c11dac
* Allow setting parameter values at build timeeschnett2013-03-25
| | | | | | | | | | | | | | | Allow setting parameter values at build time, enabling additional compiler optimisations. I measured that e.g. ML_BSSN runs 5% to 10% faster if its parameters are chosen at build time. This introduces macros CCTK_PARAMETER${thorn}${parameter}. If unset, the parameter value is taken from the parameter file (default). If set at compile time, e.g. via a -D option in CPPFLAGS, this overrides the parameter database, and DECLARE_CCTK_PARAMETERS will always use this value. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4989 17b73243-c579-4c4c-a9d2-2d5706c11dac

* Introduce OPTIONAL_IFACTIVEeschnett2013-01-18
| | | | | | | | | | | Following up on a discussion on the Cactus developers mailing list, this patch introduces a third way of indicating a desired capability: in addition to REQUIRES and OPTIONAL there is OPTIONAL_IFACTIVE. This behaves like OPTIONAL, except that the capability relationship only exists if the thorn providing the capability is active. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4938 17b73243-c579-4c4c-a9d2-2d5706c11dac

* Improve performance of Fortran index calculationseschnett2011-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | In Fortran, Cactus currently declares grid functions e.g. as (this is the expansion of DECLARE_CCTK_ARGUMENTS) REAL*8 gxx (X0metric,X1metric,X2metric) where X0metric etc. are integers passed into the routine. Each grid function group has its own, independent size. This has two disadvantages: - The compiler does not know that all grid functions have the same size (namely cctk_lsh), and thus has to perform array index calculations separately for each group - The argument list is longer than neded The enclosed patch declares grid functions via cctk_lsh. Grid arrays are still declared independently. This reduces the code size of e.g. GRHydro/GRHydro_Tmunu.F90 from 6836 to 6241 bytes on my system. I have not attempted to measure a performance difference. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4763 17b73243-c579-4c4c-a9d2-2d5706c11dac
