[Einstein Toolkit] #1650: piraha parses "-0." incorrectly

#1650: piraha parses "-0." incorrectly --------------------+------------------------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- When encountering foo::bar = -0. in parameter files, the piraha parser returns (double)0. instead of (double)-0. it is misses the signed zero that the floating point numbers provide. This makes it impossible to recover from (older) checkpoints where eg coordbase::xmin is given as -0. A possible fix is to change line 545 of Call.cc from {{{ ret->ddata = -ret->ddata; }}} to {{{ ret->ddata = std::copysign(ret->ddata, std::signbit(ret->ddata) ? 1. : -1.); }}} -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1650> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1649: HydroBase: add average atomic mass

#1649: HydroBase: add average atomic mass ---------------------------------+------------------------------------------ Reporter: dradice@… | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Other | Version: development version Keywords: | ---------------------------------+------------------------------------------ I would like to propose a patch to add a variable to HydroBase to be used to store the average atomic mass of the fluid during the evolution. This can be used, e.g., to do evolutions using a non-NSE equation of state. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1649> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1640: RK2-MR2-1 TestMoL test fails after MoL revision 225

#1640: RK2-MR2-1 TestMoL test fails after MoL revision 225 -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: MoL | -----------------------------------+---------------------------------------- It seems as if it re-uses the RHS and 225 makes MoL clear the slow sector RHS the same way it clears the fast sector RHS. The results are silently wrong by a factor of 1/2 or so. This does not seem to happen in Jenkins but happens on my workstation (found while debugging another MoL related issue). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1640> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1643: cannot compile with release version of simfactory

#1643: cannot compile with release version of simfactory ------------------------+--------------------------------------------------- Reporter: rhaas | Owner: eschnett Type: defect | Status: new Priority: blocker | Milestone: Component: SimFactory | Version: development version Keywords: | ------------------------+--------------------------------------------------- I just tried to compile with the release version of simfactory (on Gordon but that would not matter) and I get: {{{ [rhaas@gordon-ln1 Cactus]$ ./simfactory/bin/sim build --thornlist thornlists/NsNsToHMNS.th Error: required key email in section hal1 is missing Aborting Simfactory. }}} The same happens for the "user" key as well. This is most likely hidden for most users since keys in the [default] section of defs.ini.local hide this issue. email may make sense to specify in defs.local.ini but user would not seem like something that should be left to default since it is machine specific. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1643> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1634: CUDA breaks CCTK_BUILTIN_UNREACHABLE ---------------------+------------------------------------------------------ Reporter: sbrandt | Owner: Type: defect | Status: new Priority: minor | Milestone: Cactus_4.3.0 Component: Other | Version: development version Keywords: | ---------------------+------------------------------------------------------ Code containing CCTK_BUILTIN_UNREACHABLE does not compile with CUDA. In fact, there seems to be problems with calling abort() from CUDA as well. The attached patch allows compilation to proceed, but I suspect it will be hated. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1634> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1629: Use DANE for server certificates

#1629: Use DANE for server certificates -------------------------------------+-------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: optional | Milestone: Component: EinsteinToolkit website | Version: development version Keywords: | -------------------------------------+-------------------------------------- If I understand correctly, DANE (<http://www.heise.de/newsticker/meldung /DANE-Bund-sichert-nach-Mail-Transport-auch-Webservice-mittels-DANE- ab-2215929.html>, <http://en.wikipedia.org/wiki/DNS- based_Authentication_of_Named_Entities>) would allow server owners to publish their certificates with their DNS entries. This could -- if I understand correctly -- replace the need for having certificates signed by a CA, which is always expensive and cumbersome. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1629> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1608: ScalarWave thorn build error on Stampede

#1608: ScalarWave thorn build error on Stampede --------------------------------------------+------------------------------- Reporter: jonah.maxwell.miller@… | Owner: Type: defect | Status: new Priority: optional | Milestone: ET_2014_05 Component: EinsteinToolkit thorn | Version: development version Keywords: ScalarWave,OpenMP | --------------------------------------------+------------------------------- When I try to compile the Einstein toolkit on stampede, I get a series of errors relating to OpenMP loops. Each error is of the form: {{{ must have a loop-invariant increment of integer, pointer, or random access iterator type for (int tk = tiled_imin[2]; tk < tiled_imax[2]; tk += tile_size_l[2]) }}} The error is definitely in the ScalarWave thorn, because disabling this thorn allows the toolkit to compile just fine. Attached are the thornlist used and the error output. The command I used to compile was {{{ sim build dgfe2 --thornlist=dgfe2_jm.th }}} -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1608> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

In particular, the current dev-version of HydroBase contains (will in a few hours) contain two different versions of it, depending on where it is defined. The needs to be cleaned up before the next release. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1409> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
