* 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

The configuration stage sets the F77 flags to the F90 flags if an F90 compiler is found. This flag setting was done too early, namely before the default values for the F90 flags were set. This flag setting has been moved to a later time. The link command used undefined make variables $(OPTIMISE_C) etc. These variables have been removed. Instead $(CXX_OPTIMISE_FLAGS) etc. are added to the link statement. This makes the linker pick up the correct flags e.g. for profiling. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4327 17b73243-c579-4c4c-a9d2-2d5706c11dac

It also includes an overall cleanup of the code, which begain with the first bug fix, and resulted in the discovery of the second bug. The first bug fix was to put in use strict; (According to L. Wall, a Perl file without use strict constitutes a bug.) This resulted in lots of errors about variables needing their scope to be specified. So I did this. At the end, I found that I couldn't fix a certain occurrance of $group. There was no sensible way that it was being set. The code was to produce a warning concerning creating groups with mixed dimensions. See 'warn_mixeddim_gfs'. The Perl code was taking a global value of $group set at build time to be the last group in a loop. However, the offending group is determined at run time in CreateThornGroupInitializers. So the warning message would typically be wrong.

The problem has been that Cactus based CCTK_REAL16 on support for the C type 'long double'. This would cause it to create Fortran code for REAL*16, a type which was sometimes not supported. In particular, on a 64-bit Athlon machine with Gnu 4.1.0, gfortran defines REAL*8 but not REAL*16, while gcc defines 'long double'. This caused thorn AEIThorns/Fortran to fail to compile. This patch causes the configuration to directly compile Fortran code that features REAL*16, and define CCTK_REAL16 only if that compiles *and* C's 'long double' is supported. When you make config, you will see a new line about Fortran REAL*16. I have tested the enclosed patch on my laptop with Gnu 4.10 and Intel 9.0 compilers 64-bit AMD Athlon with same compilers POWER4 with IBM XL compilers BUT NOTE: I have severe doubts about using REAL*16 on any of these architectures. That 16-byte (128-bit) type is not natively supported on the Xeon, Athlon, or POWER machines. While some compilers support such types, calculation is done in software, not on the FPU. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4314 17b73243-c579-4c4c-a9d2-2d5706c11dac

| | | | | | | | | | | | | | | | | | | | | | http://www.cactuscode.org/old/pipermail/patches/2006-April/000160.html ... a patch for the known-architectures file for Darwin for the XLF compiler. Primarily it is to improve the speed, by making the optimization options to be -O3 -qhot -qarch=auto -qtune=auto -qcache=auto This gets quite good performance, but moves instructions. The various "auto's" cause the compiler to generate optimal code for the platform on which the compiler is running. Also, I made it supress the congratulatory message ("Yay, I compiled"). Also, I test the compiler version major and minor numbers so that darned "-no-cpp-precomp" option is included only when the version is less than 3.3. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4313 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
