[Einstein Toolkit] #972: Add PETSC_INC_DIRS etc. to ExternalLibraries/PETSc

#972: Add PETSC_INC_DIRS etc. to ExternalLibraries/PETSc ----------------------------------------------------+----------------------- Reporter: Erik Schnetter <schnetter@…> | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | ----------------------------------------------------+----------------------- The thorn ExternalLibraries/PETSc does not provide variables called PETSC_INC_DIRS, PETSC_LIB_DIRS, PETSC_LIBS to allow overriding the auto- detected defaults. When the auto-detecting mechanism fails, one currently has to use the global options SYS_INC_DIRS, LIBDIRS, and LIBS to ensure the PETSc files are found at build time. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/972> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #935: HTTPD can use large amounts of memory for its hash table of pages

#935: HTTPD can use large amounts of memory for its hash table of pages -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: HTTPD | -----------------------------------+---------------------------------------- I just found that for an (stripped down!) parameter file of my production simulations HTTPD creates a Hash table via functions in CACTUS_HOME/src/util/Hash.c that consumes 1GB of memory (for the array of pointers that is the top level hash table structure) to hold about 10000 entries. I am not sure if this is due to a poor choice of hashing function (util_HashHash) or the fact that it doubles the size of the table until the number of entries is smaller than the number of hash slots in (in Util_HashRehash and Util_HashAdd). It was somewhat unexpected that a non- science thorn would use that much memory. Alternatives to use less memory might be to increase the filling factor ie. only rehash if hash->keys > 10*hash->fill (maybe starting from some limit of keys) or to use something like the binary tree implementation in BinaryTree.c (but not that one since it is broken in at least two places). I simple linear list might also be sufficient since HTTPD does not have to be lightning fast and serve hundreds of request per second I expect. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/935> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #966: Carpet always calls POSTREGIRD on the finest level

#966: Carpet always calls POSTREGIRD on the finest level -------------------------+-------------------------------------------------- Reporter: rhaas | Owner: eschnett Type: enhancement | Status: new Priority: minor | Milestone: Component: Carpet | Version: Keywords: | -------------------------+-------------------------------------------------- While looking at #965 Christian Reisswig and I noticed that Carpet seems to call the routines on the finest level whenever any recompose happened. This is ok to ensure that global (also global-late) routines are called but also means that local routines are called. In cases where the finest level did not actually change (happens in core collapses we believe), this causes unnecessary calls to eg. MoL_PostStep with its attending SYNC calls. This might be candidate for optimization. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/966> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #751: Carpet fails when running qc0-mclachlan.par

#751: Carpet fails when running qc0-mclachlan.par --------------------+------------------------------------------------------- Reporter: rhaas | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: Component: Carpet | Version: Keywords: | --------------------+------------------------------------------------------- this is due to ggf::transfer_from_all line 613 (dst->transfer_from) where dst is NULL: {{{ 03 assert (lc1>=0 or lc2>=0); 604 605 // Source and destination data 606 gdata * const dst = 607 lc1>=0 ? storage.AT(ml1).AT(rl1).AT(lc1).AT(tl1) : NULL; 608 cdata const & srcs = srcstorage.AT(ml2).AT(rl2); 609 for (int i=0; i<(int)gsrcs.size(); ++i) { 610 gsrcs.AT(i) = lc2>=0 ? srcs.AT(lc2).AT(tl2s.AT(i)) : NULL; 611 } 612 613 dst->transfer_from 614 (state, gsrcs, times, recv, send, slabinfo, p1, p2, time, pos, pot); }}} which causes a segfault in line 613. lc1 is -1 in this case and passes the assert in line 603. Since dst is used as a pointer it may never be NULL. It can be reproduced with the qc0-mclachlan.par example from simfactory. Tested on Caltech's bethe workstation with 12 MPI processes and no OpenMP. hg blames commit 5418b354a3ab which seems to be the original Carpet import into mercurial so this seems to be caused by something else. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/751> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #958: schedule hydrobase_InitExcisionmask global-early loop-local

#958: schedule hydrobase_InitExcisionmask global-early loop-local ----------------------------------+----------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit trac | Version: Keywords: HydroBase | ----------------------------------+----------------------------------------- Christian Ott found that right now the scheduling of EinsteinUtil/SetMask_SphericalSurface::SetMask_SphericalSurface and HydroBase::HydroBase_InitExcisionMask conflict in the Post_Recover_Variables and INITIAL since SetMask_SphericalSurface which needs to run after HydroBase_InitExcisionMask is scheduled GLOBAL which happens to be global-late in these bins. SetMask_SphericalSurface must be local since it must run after SphericalSurfaceHasBeenSet which is after SphericalSurface_Set which is GLOBAL. The attached patch runs HydroBase_InitExcisionMask global-early loop-local instead. Pleas note that the patch will change the behaviour in PostRegrid slightly since HydroBase_InitExcisionMask (and not just SetMask_SphericalSurface which already does so) will run on all refinement levels, always, independent of the iteration counter and Carpet's do_every logic. The current code prevents properly recovering from checkpoints. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/958> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

Since global-early ,loop-local routines run before this happens, they see inconsistent data structures and trigger the out-of-bounds error in enter-level-mode. This is a recently triggerable issue, since before 55759e108807 Carpet would not call global-early routines in PostRegrid and the first such routine is HydroBase_InitExcisionMask which was recently made global-early, loop- local. Reverting these changes does not seem like a good option for the reasons outlined in #958. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/971> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

This is useful for hydro runs to not abort a run if a NaN is found on a very coarse level where it will be overwritten afterwards. The second patch adds OpenMP to NaNChecker. It also converts to code to C++ and uses templates instead of macros. Both patches pass the testsuite in NanChecker (in their default setting). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/968> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
