[Einstein Toolkit] #1624: remove MOLDOESCOMPLEX from MoL

#1624: remove MOLDOESCOMPLEX from MoL -----------------------------------+---------------------------------------- Reporter: knarf | Owner: Type: enhancement | Status: new Priority: optional | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- MOLDOESCOMPLEX is an old #define in MoL, and seems to be unused for quite some time now. It also comes with the comment "even using it probably doesn't work" in the commit. I suggest to remove it (removing the code within). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1624> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1518: Parameter parser and CCTK_ParameterSet interpret leading zeros in numbers differently

#1518: Parameter parser and CCTK_ParameterSet interpret leading zeros in numbers differently --------------------+------------------------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- the parameter parser allows things like: {{{ thorn::param1 = 011 thorn::param2 = 012.34 }}} in parameter files. For floating point values this is a bit unexpected but otherwise mostly harmless. For integers the situation is a bit more complex since in C a leading zero is used to indicate a octal number. And (worse) while the parameter file parser converts the string "011" to the number 11 the Cactus call CCTK_ParameterSet will convert it to 9. The difference is ultimately the difference between calling atof (Parser) and strtol (CCTK_ParameterSet). To avoid confusion it would likely be good to change CCTK_ParameterSet to behave the way the Parameter parser does. This is a change in behaviour compared to the pre-Piraha parser, however I suspect the number of users that actually used octal (or hexedecimal) notation in their parameter files is small. The change is to change {{{inval = strtol (value, &endptr, 0);}}} to {{{inval = strtol (value, &endptr, 10);}}} in line 2209 of src/main/Parameters.c and similar in line 2270. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1518> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1635: hwloc requires a certain minimum version, but does not check for it

#1635: hwloc requires a certain minimum version, but does not check for it --------------------+------------------------------------------------------- Reporter: knarf | Owner: Type: defect | Status: new Priority: major | Milestone: ET_2014_11 Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- Currently, hwloc's configuration.sh searched for any hwloc library and uses it. However, it requires a pretty new version within some of its own files, which leads to build failure on, e.g. Debian stable systems. The attached patch uses pkg-config to get the version of the installed hwloc library and if that version is older than 1.6 (educated guess, but see http://lists.einsteintoolkit.org/pipermail/users/2013-February/002860.html), builds the bundled version even if another version is installed (but too old). Note that this is done (intentionally) only if no library was specified, and the script was looking for it by itself. This allows users to specify something which will not be overwritten by this mechanism. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1635> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #428: Forbid configuration names ending in -reconfig

#428: Forbid configuration names ending in -reconfig ----------------------+----------------------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: Cactus | Version: Keywords: | ----------------------+----------------------------------------------------- I accidentally created a Cactus configuration with a name like "sim- reconfig". This confuses Cactus, because the command "make sim-reconfig" can then mean either to build the "sim-reconfig" configuration, or to reconfigure the "sim" configuration. Cactus should catch and forbid these cases. This is probably most cleanly handled by using a script instead of a Makefile to interpret the user commands. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/428> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1610: Switch Cactus to 64 bits

#1610: Switch Cactus to 64 bits -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Cactus | Version: development version Keywords: | -------------------------+-------------------------------------------------- Although pointers can have 64 bits, integers in Cactus are de facto (since we use "int" in many places) restricted to 32 bits. This limit is easily reached, and this has in fact been a problem on at least two occasions. One issue comes from Carpet's numbering of grid points. With 25 refinement levels, the coarse grid can be at most 127^3, and this limit was reached in production simulations years ago. Another issue comes from large 1D arrays. It is easily possible to have a 1D array with 10M (10^7) elements that is replicated across processes (distrib=const). In this case, one can use at most 200 MPI processes. We should devise a plan to switch Cactus to 64 bits. One option would be to replace most "int" by "CCTK_INT", so that those affected can switch these to 64 bits. I want to note that using 64-bit loop counters is often slightly faster than using 32-bit loop counters (on 64-bit architectures), since the 32->64 bit conversion for array indexing can be omitted. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1610> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1565: change default of IOUtil::out_save_parameters to true

#1565: change default of IOUtil::out_save_parameters to true -------------------------+-------------------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: optional | Milestone: Component: Cactus | Version: development version Keywords: | -------------------------+-------------------------------------------------- it would be useful of HDF5 files contained the full set of parameter values. This can be used by postprocessing scripts to find out eg about the symmetry conditions or some of the grid structure parameters as well as atmosphere settings. IOUtil::out_save_parameters controls whether the full set of parameters or only those that have been steered are written to file (for regular output, checkpoints always write all parameters). I would like to change the default so that all parameters are always written. If feasible I would even want to write all parameter changes to file (either as full parameter dumps for each output or as a full dump when the simulation starts then deltas afterwards). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1565> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

It should use the evolved Gamma variables instead of taking metric derivatives.

#1636: check and abort if more timelevels are requested than time hierarchy supports -------------------------+-------------------------------------------------- Reporter: rhaas | Owner: eschnett Type: enhancement | Status: new Priority: minor | Milestone: Component: Carpet | Version: development version Keywords: | -------------------------+-------------------------------------------------- In order to provide a more user friendly fix for #626 we want to change Carpet (and PUGH?) such that they check at runtime, when memory is allocated that the number of requested timelevels is less or equal than what the time hierarchy (controlled by the max_timelevels) parameter supports. This check should be done early and should take the checkpoint tag as well as prolongation operator tags into account. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1636> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
