[Einstein Toolkit] #1906: CarpetRegrid2: possible off-by-one error when using regrid_every parameter

#1906: CarpetRegrid2: possible off-by-one error when using regrid_every parameter ---------------------------+------------------------------------------------ Reporter: bmundim | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: Component: Carpet | Version: development version Keywords: CarpetRegrid2 | ---------------------------+------------------------------------------------ I was working on a par file for a quick regridding test and found out an unexpected behaviour regarding regridding. Basically I want a par file with a few iterations such that it adds a refinement level every 4 iterations for example. I set the following parameters then: {{{ CarpetRegrid2::add_levels_automatically = "yes" CarpetRegrid2::regrid_every = 4 }}} for a grid structure as such: {{{ Cactus::cctk_itlast = 10 CoordBase::xmin = -0.5 CoordBase::ymin = -0.5 CoordBase::zmin = -0.5 CoordBase::xmax = 0.5 CoordBase::ymax = 0.5 CoordBase::zmax = 0.5 CoordBase::ncells_x = 16 CoordBase::ncells_y = 16 CoordBase::ncells_z = 16 Carpet::max_refinement_levels = 3 CarpetRegrid2::num_centres = 1 CarpetRegrid2::active_1 = "yes" CarpetRegrid2::num_levels_1 = 1 CarpetRegrid2::radius_1[1] = 0.12 CarpetRegrid2::radius_1[2] = 0.04 }}} I was expecting then regridding to happen at iterations 4 and 8, however if you run the attached par file, a modification of balsara shocktube test, you see that the level additions actually happen at iterations 5 and 9 instead: {{{ ... INFO (CarpetRegrid2): Increasing number of levels of centre 1 to 2 (it=5) ... INFO (CarpetRegrid2): Increasing number of levels of centre 1 to 3 (it=9) }}} which is apparently an off-by-one kind of error. I tracked down the code producing these messages and it comes from function CarpetRegrid2_RegridMaps at CarpetRegrid2/src/regrid.cc, lines 745 to 747. In order for that piece of code to execute we do have to have do_recompose set to true. Strangely the condition to set it, compares the previous iteration to the regrid_every parameter on line 707 of the same file: {{{ (cctk_iteration - 1) % regrid_every == 0 }}} Investigating if this actually makes sense I was led to what I think it might be the source of the problem on line 58 of Carpet/src/Evolve.cc. Time and iteration is advanced before calling CallRegrid. Skimming over the AdvanceTime routine it is not clear to me that it really needs to be called before CallRegrid. If it is really needed then why the condition to regrid or not is not taken on the current updated iteration as in: {{{ cctk_iteration % regrid_every == 0 }}} Thanks, Bruno -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1906> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1778: Scheduling WHILE Loops in CCTK_ANALYSIS Results in Hang --------------------------------+------------------------------------------- Reporter: zachetie@… | Owner: Type: defect | Status: new Priority: unset | Milestone: Component: Other | Version: ET_2015_05 Keywords: | --------------------------------+------------------------------------------- When encountering a WHILE loop inside CCTK_ANALYSIS, Cactus simply hangs. I have created a simple thorn, ScheduleTester, that reproduces this problem 100% of the time. The thorn only takes as input the number of iterations desired in the WHILE loop. I have attached this thorn, as well as example .par and ThornList files to this ticket. This problem is verified to exist within 2015_05 as well as 2014_11 ET releases. I have not tried past releases. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1778> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #2162: buliding the ET on a new machine is hard

#2162: buliding the ET on a new machine is hard ---------------------------------+-------------------- Reporter: Roland Haas | Type: defect Status: new | Priority: major Milestone: | Component: Other Version: development version | Keywords: ---------------------------------+-------------------- Building the ET on unknown clusters and even on workstations and laptops is hard and often leads to failures. Simfactory adds another layer of scripts making it harder for new users to diagnose the problem. The education and outreach working group (Gabrielle, Manuela, Helvi, Harrison) are involved in simplifying this. We do have a wiki page on how to add a new cluster to simfactory: https://docs.einsteintoolkit.org/et-docs/Configuring_a_new_machine which is however fairly unknown and also not very complete. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2162> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1992: provide bibtext snippets for requested cittations on ET website ----------------------------+----------------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus website | Version: development version Keywords: | ----------------------------+----------------------------------------------- Our citing page http://einsteintoolkit.org/documentation/licenses/ right now lists the bibtex key and the doi for the requested citations. It would be useful to make the bibtex keys hyperlinks to a bibtex fragment for the paper in question that could be copied and pasted into a user's bibtext file. If we don't want to use the fragment from our own einsteintoolkit.bib we could use INSPIRE's doe search facility using "bibtex" as the output format, eg: http://inspirehep.net/search?ln=en&ln=en&p=doi%3A10.1088%2F0264-9381%2F21%2… for the Carpet reference. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1992> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #2136: integrate server status page into ET website

#2136: integrate server status page into ET website ---------------------------------+------------------------- Reporter: Roland Haas | Type: enhancement Status: new | Priority: minor Milestone: | Component: Other Version: development version | Keywords: ---------------------------------+------------------------- There are at least two different server uptime monitors that we use in the ET: * Frank's at: https://www.cct.lsu.edu/~knarf/cgi-bin/monitor.cgi * Ian's at: https://etstats.barrywardell.net/ which uses the uptimerobot service It would be nice to have one or both linked from the ET website and ideally have a warning about when servers are down on the main ET site. The warning can be done with a bit of javascript and css using API keys for uptimerobot (attached is some sample html for this) eg here: https://etstats.barrywardell.net/ -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2136> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
