#683: LSUThorns/Vectors: Remove pos, add sin/cos/tan functions -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- Remove kpos, because it is not used (it is a no-op, i.e. the arithmetic + operator). Add sin, cos, and tan. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/683> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#223: Make declaration of CCTK_ARGUMENTS safer -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- I suggest to change the declaration of CCTK_ARGUMENTS in C from cGH * cctkGH to cGH const * CCTK_RESTRICT const cctkGH which should lead to safer code and may even enable some optimisations. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/223> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #688: Carpet timers are slow

#688: Carpet timers are slow -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- The Carpet timers (file CactusTimers.cc) performs unnecessary work that is not necessary unless timers_verbose is given. It calls the flesh to obtain the timer name, converts this to a C++ string (malloc/free), and back to a C string. This is due to the API of msgStart and msgStop. The routine serialise changes the output stream properties by modifying the output format (scientific) and the precision. This should be undone afterwards in the same routine. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/688> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #687: Display allocation information
by Einstein Toolkit 28 Nov '11

#687: Display allocation information -------------------------+-------------------------------------------------- Reporter: hinder | Owner: eschnett Type: enhancement | Status: new Priority: minor | Milestone: Component: SimFactory | Version: Keywords: | -------------------------+-------------------------------------------------- SimFactory could provide a command to display the usage information of the user's allocation on a machine. For example, {{{ $ sim show-allocation Allocation: TG38372811 Total: 100000 Used: 10000 Used by <user>: 50000 Remaining: 90000 }}} Some systems will not be able to provide all this information, and some will not have the concept of an allocation. The output should be easy to parse by scripts (e.g. for updating group web pages). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/687> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

Re: [ET Trac] [Users] [Einstein Toolkit] #677: parameter default change in CarpetIOASCII
by Erik Schnetter 26 Nov '11

26 Nov '11

Luca I didn't mean to disagree with you: it may indeed be time to make Carpet's ASCII output more user friendly but omitting ghost zones, i.e. to change the defaults for some of the parameters you mentioned. However, for the deprecated parameter, the plan is to make them go away (or to turn them into no-ops, i.e. to completely ignore them in the code). -erik On Sat, Nov 26, 2011 at 8:23 PM, Luca Baiotti <baiotti(a)ile.osaka-u.ac.jp> wrote: > On 25/11/11 4:58 AM, Einstein Toolkit wrote: >> #677: parameter default change in CarpetIOASCII >> ----------------------------------------+----------------------------------- >> Reporter: baiotti@… | Owner: eschnett >> Type: enhancement | Status: new >> Priority: optional | Milestone: >> Component: Carpet | Version: >> Resolution: | Keywords: CaroetIOASCII parameter default >> ----------------------------------------+----------------------------------- >> >> Comment (by eschnett): >> >> A quick note: If a parameter is deprecated, it should not be used if >> possible, and consequently its default should not be changed either. > > I think that no one uses 3D ASCII output, so those two (of the four) > parameters are irrelevant, but in general I don't agree.

[Einstein Toolkit] #679: Add kifneg function

#679: Add kifneg function -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- Subject: Add kifneg function From: Erik Schnetter <eschnetter(a)perimeterinstitute.ca> Date: 2011-11-26 Add an kifneg function that does the opposite of kifpos, because kifneg is more natural (in the same sense as "ifnotzero" is natural in C.) Incidentally, it should probably be renamed "ifmsb" instead, because it can also be applied to unsigned quantities which don't have a sign bit. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/679> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #425: Case sensitivity GSL_DIR=BUILD

#425: Case sensitivity GSL_DIR=BUILD ----------------------------------------+----------------------------------- Reporter: reisswig@… | Type: enhancement Status: new | Priority: minor Milestone: | Component: Cactus Version: | Keywords: GSL_DIR BUILD ----------------------------------------+----------------------------------- The thorn GSL would not compile if "GSL_DIR=build" in the option list. In order to work, it requires "GSL_DIR=BUILD", i.e. it is really case sensitive although I think, this is not required and should be case insensitive. Possibly, HDF5_DIR=build may also not work for the same reason (have not checked; should be checked as well). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/425> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#234: Carpet mailing list is not functioning --------------------+------------------------------------------------------- Reporter: hinder | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: Component: Carpet | Version: Keywords: | --------------------+------------------------------------------------------- The Carpet mailing list has been unavailable since 22-Mar-2010. This list provides a forum for discussion of Carpet features and issues, and would be the first port-of-call for new users. As such I think it would be good to resurrect the mailing list. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/234> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#671: ML_ADMConstraints is incorrect -----------------------------------+---------------------------------------- Reporter: hinder | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: ML_ADMConstraints | -----------------------------------+---------------------------------------- ML_ADMConstraints does not compute the constraints correctly. There are errors in the computation of the Ricci tensor. The attached patch corrects these errors.
