[Einstein Toolkit] #1454: main timer has value 0 in timer tree XML output

#1454: main timer has value 0 in timer tree XML output --------------------+------------------------------------------------------- Reporter: hinder | Owner: eschnett Type: defect | Status: new Priority: minor | Milestone: Component: Carpet | Version: development version Keywords: | --------------------+------------------------------------------------------- The "main" timer is reported with value 0 in the timer tree XML output: {{{ <timer name = "main"> 0 <timer name = "CarpetStartup"> 0.239015 <timer name = "AllocateGridHierarchy"> 0.030772 </timer> <timer name = "CarpetLib::dh::recompose"> 8.8e-05 </timer> <timer name = "CarpetLib::dh::regrid"> 0.000339 </timer> <timer name = "CarpetLib::gh::regrid"> 0.183402 ... }}} I don't know if the timer itself is zero, or if the XML output treats "main" specially. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1454> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1453: Carpet: skip CheckFence routine if CarpetLib::electric_fence is false

#1453: Carpet: skip CheckFence routine if CarpetLib::electric_fence is false --------------------+------------------------------------------------------- Reporter: rhaas | Owner: eschnett Type: defect | Status: new Priority: minor | Milestone: Component: Carpet | Version: development version Keywords: | --------------------+------------------------------------------------------- the attached patch makes Carpet check CarpetLib::electric_fence before checking for out-of-bound access. Just enumerating all variables is apparently already expensive enough to show up in the Timer report. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1453> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1452: config.guess doesn't recognize arm-linux-gnueabihf
by Einstein Toolkit 10 Oct '13

#1452: config.guess doesn't recognize arm-linux-gnueabihf ----------------------+----------------------------------------------------- Reporter: knarf | Owner: Type: defect | Status: new Priority: optional | Milestone: Component: Cactus | Version: development version Keywords: | ----------------------+----------------------------------------------------- The current version of config.guess in Cactus doesn't correctly recognize arm-linux-gnueabihf as such, but as gnueabi. Most likely this is due to an old version of this file, I found newer versions containing checks for this - but didn't test just updating this file nor any other part of the configure state for this. There is currently no known downside, but if possible an update would be nice. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1452> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1450: Cactus support for armv6l architecture -------------------------+-------------------------------------------------- Reporter: knarf | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus | Version: development version Keywords: | -------------------------+-------------------------------------------------- The attached patch adds support for the armv6l architecture to Cactus, essentially just pointing to linux. It also tells Cactus about the number of cacheline bytes on that architecture (32). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1450> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1451: add path to searchpath of some libraries

#1451: add path to searchpath of some libraries -----------------------------------+---------------------------------------- Reporter: knarf | Owner: Type: enhancement | Status: new Priority: minor | Milestone: ET_2013_11 Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- These four patches add another search path to some of the external libraries (lib/arm-linux-gnueabih). We should do this better in some way at some point, but for the moment I don't have the time for this, and these patches both work on this architecture and shouldn't cause any harm on others. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1451> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1448: move PARAMCHECK before WRAGH

#1448: move PARAMCHECK before WRAGH --------------------+------------------------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- currently PARAMCHECK runs after WRAGH which means that the lev0 data and grid arrays as well as grid scalars have storage (but the grid is not yet set up properly since basegrid did not yet run). This means that memory to hold level 0 has been allocated which can be quite large (eg for mulitpach runs where level 0 encompases all multipatch grids). Therefore using cactus_sim -P parfile.par to test parameters and parameter values before submitting a job (which is good practise) can potentially cripple the head node on which one tries this. Would it be possible to to swap the order (and make sure to call CCTKi_FinaliseParamWarn right after PARAMCHECK) or is do we require that storage exists during PARAMCHECK? For the code that provides the current ordering, see CallSetup in Carpet/src/Initialise.cc and src/main/CactusDefaultInitialise.c (in the flesh). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1448> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1447: support "replay" mode

#1447: support "replay" mode -------------------------+-------------------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Cactus | Version: development version Keywords: | -------------------------+-------------------------------------------------- for postprocessing it would be useful to have read in data in hdf5 files step by step and apply analysis routines to the saved data. For this it would be useful if there was some suport in the flesh and driver eg: * set time and iteration based on what is found in the data file * read grid structure from data * create grid functions for data in files without having to activate the corresponding thorns (which might be an evolution thorn whose evolution cannot be disabled or that depends on very many other thorns) -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1447> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1412: Memory leak on development branch

#1412: Memory leak on development branch -----------------------------------+---------------------------------------- Reporter: hopper.seth@… | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: Component: Carpet | Version: development version Keywords: | -----------------------------------+---------------------------------------- I am seeing what appears to be a memory leak that has showed up since the Gauss release. I have run the same parameter file on Gauss and the development branch, and see linear growth in memory usage in the development version. From standard out it looks to be a bug in Carpet, as the memory usage jumps after re-gridding. I've attached: - The parameter file, bbhCart2-3.rpar. It runs on 12 cores on Datura. - Plots showing the memory usage per process in the two cases. - Standard out from the two cases. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1412> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1445: add tags to disallow splitting in directions

#1445: add tags to disallow splitting in directions -------------------------+-------------------------------------------------- Reporter: rhaas | Owner: eschnett Type: enhancement | Status: new Priority: minor | Milestone: Component: Carpet | Version: development version Keywords: | -------------------------+-------------------------------------------------- the attached patch adds a new tag "no_split_directions" which can be used to prevent a grid array to be split in the given directions when processor decompositions is done. I currently explicitly forbid this tag to be used in grid functions since all grid functions share the same processor decomposition so using this tag on a per-function basis is impossible. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1445> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
