[Einstein Toolkit] #1256: scheduling MoL_PostStep in Post_Recover_Variables

#1256: scheduling MoL_PostStep in Post_Recover_Variables --------------------+------------------------------------------------------- Reporter: rhaas | Owner: Type: task | Status: new Priority: major | Milestone: Component: Cactus | Version: Keywords: MoL | --------------------+------------------------------------------------------- this is not ideal since some routines in MoL_PostStep will always change results (eg. Con2Prim). We already removed MoL_PostStep from the past timelevels since the prolongation cannot be handled properly. Originally (MoL rev 137, https://trac.einsteintoolkit.org/changeset/137/CactusNumerical/MoL) was introduced to enforce boundary conditions and recompute the ADM variables. Since then the policy has changed and the ADM variables are supposed to be checkpointed (rule of thumb is that anything with more than one timelevels should be checkpointed). When recovering from a checkpoint the boundary conditions are currently satisfied since CarpetIOHDF5 reads in everything that it can, incl. data in ghost and boundary zones. This method ensures that bit identical data is read in. Unfortunately running MoL_PostStep then changes values. It seems as if MoL_PostStep is never required so should not be run. The attached trivial patch adds a parameter to MoL to disable running in Post_Recover_Variables. Note that this is not yet are request for review but a work item since more testing is required to decide if anything breaks when MoL_PostStep is not run. Tests done with GRHydro (and changes so that eg. the atmosphere mask is identical in ghost zones [currently it is not valid in ghost zones but also never checked in ghost zones]) gives bit identical results even when changing the number of processors while recovering. This is a very simple test though. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1256> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1297: Reduce time spent in cycling timelevels if there is only one timelevel.

#1297: Reduce time spent in cycling timelevels if there is only one timelevel. --------------------------------------+------------------------------------- Reporter: diener | Owner: eschnett Type: enhancement | Status: new Priority: major | Milestone: Component: Carpet | Version: development version Keywords: performance optimization | --------------------------------------+------------------------------------- I noticed in a run with gridfunctions with only 1 timelevels that a significant amount of time was spent cycling timelevels. The attached patch makes the routine bypass a lot of code, if a grid variable only has 1 timelevel. This reduces the total time spent in cycling timelevels from 417 s to 0.8 s for a run of 32767 iterations. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1297> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #705: Activation Order in Parameter Files

#705: Activation Order in Parameter Files -------------------------+-------------------------------------------------- Reporter: sbrandt | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Cactus_4.1.0 Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- At the moment the ActiveThorns list is sensitive to the order in which thorns are activated if the ActiveThorns parameter is updated multiple times. However, it is not sensitive to the order in which thorns are activated if all thorns are specified in a single line. This inconsistency should be removed, and the order should not matter in either case. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/705> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #519: Add all ET repositories to TRAC

#519: Add all ET repositories to TRAC ----------------------------------+----------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit trac | Version: Keywords: | ----------------------------------+----------------------------------------- TRAC provides integration with version control systems. It has a list of repositories, and specific changesets and files can be referred to in ticket comments and wiki pages using a convenient syntax. Several ET repositories have been added already. I think this feature is useful, and that the remaining repositories should be added. It would be nice if the links were easier to type. I propose omitting the arrangement name from the repositories, as all thorn names are probably unique, and avoiding spaces which require extra quoting. We have several repositories in Git and Mercurial. It would be nice to include those as well. I believe that there are TRAC plugins to accomplish this in the same way as for SVN. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/519> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #650: User is not asked for Mercurial authentication information initially
by Einstein Toolkit 23 May '13

#650: User is not asked for Mercurial authentication information initially ---------------------------+------------------------------------------------ Reporter: hinder | Owner: eric9 Type: defect | Status: new Priority: major | Milestone: Component: GetComponents | Version: Keywords: | ---------------------------+------------------------------------------------ When running GetComponents without the "-a" (anonymous) option, the user is asked initially for authentication information for any authenticated repositories. However, the Carpet repository is not included in this list. This leads to the authentication prompt much later when Carpet is actually being checked out, and here it is not possible to say "anonymous". I believe the problem occurs on line 846 of GetComponents: {{{ # if AUTH_URL is defined we want to find the username: if ( defined( $component->{AUTH_URL} ) and ( $component->{TYPE} eq 'cvs' or $component->{TYPE} eq 'svn' or $component->{TYPE} eq 'darcs' or $component->{TYPE} eq 'git' ) ) { }}} where Mercurial (hg) is not included in that list. The attached (untested) patch adds hg to that list, but I don't know if this is sufficient to fix the problem. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/650> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1229: provide downloadable tarball of ET

#1229: provide downloadable tarball of ET -------------------------------------+-------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit website | Version: Keywords: | -------------------------------------+-------------------------------------- I created a mock up download page (with one paragraph changed) with a tar ball of the current release version of the ET. http://www.tapir.caltech.edu/~rhaas/ET/ To provide the tarball we would need some way to store data on the web- sever that is not archived via svn (or live with ~200MB commmits). Alternatively I am happy to have the tarball live in in my webspace and keep the link though a more "permanent" storage site might be more useful. The tarball would need to be updated whenever the release branch(es) change. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1229> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

Only their "V" equivalents and their macro equivalents are documented. In addition, I see that the documentation claims that these three functions are "internal" functions. This is not true -- if this was true, they would have CCTKi_ prefixes. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1267> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
