* 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

| | | | | | | | | | | | | | | | | (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

* Fix inconsistent interpretation of CCTK_ParameterQueryTimesSet()'s return value.tradke2006-09-28
| | | | | | | | | | | | | | | | | | | | The discussion on http://www.cactuscode.org/pipermail/developers/2006-August/004990.html brought up the issue of an inconsistent interpretation of CCTK_ParameterQueryTimesSet()'s return value which depends on whether this is a normal run, or one that has been recovered from a checkpoint. The provided patch solves the problem of inconsistent behaviour of CCTK_ParameterQueryTimesSet() by fixing the code in CCTK_ParameterSet() which increments the times_set counter. Now the counter is not incremented for recovered parameters which take the same value as before (effectively assuming this to be a no-op). In addition, non-steerable parameters which are set in the parfile but then recovered to the same value from a checkpoint will have their previous set operation unregistered. In a recovered run, CCTK_ParameterQueryTimesSet() will now return a value larger 0 for the union of - all parameters which have been set in the parfile when the checkpoint was created - all steerable parameters which have been set in the recovery parfile This closes PR Cactus-2056: "fix inconsistent interpretation of CCTK_ParameterQueryTimesSet()'s return value". git-svn-id: http://svn.cactuscode.org/flesh/trunk@4374 17b73243-c579-4c4c-a9d2-2d5706c11dac

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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The symptoms were that if you (a) set the same parameter twice, *and* (b) the second setting is an invalid value, then current-CVS Cactus core-dumps inside the flesh trying to free() a garbage (uninitialized) pointer. For example, the following par file suffices to trigger the core-dump, using only flesh parameters (*no* thorns activated): # this par file causes a core dump in current-CVS Cactus Cactus::cctk_timer_output = "off" Cactus::cctk_timer_output = "foo" # an illegal value for this parameter Looking at the code, 599 /* check if a parameter is set more than once in a parfile */ 600 if (cctk_parameter_set_mask == PARAMETER_RECOVERY_PRE && 601 param->props->n_set > 0) 602 { 603 if (retval == 0) 604 { 605 new_value = CCTK_ParameterValString (param->props->name, 606 param->props->thorn); 607 retval = strcmp (old_value, new_value) ? -10 : -11; 608 } 609 free (new_value); 610 } Notice that the free() at line 609 may be executed even if new_value was *not* assigned a value at line 605. Alas, new_value is a local variable in this function, and is not explicitly initialized, so it has a garbage value initially... and line 605 is its only assignment in this function. The fix is easy -- just move the free() up to right after line 607, so it's executed if and only if new_value has been assigned. patch was http://www.cactuscode.org/old/pipermail/patches/2006-April/000162.html developers discussion was http://www.cactuscode.org/old/pipermail/developers/2006-April/001758.html http://www.cactuscode.org/old/pipermail/developers/2006-April/001759.html git-svn-id: http://svn.cactuscode.org/flesh/trunk@4285 17b73243-c579-4c4c-a9d2-2d5706c11dac
