Keep track of masked-out volume in CarpetMask

Issue #434 closed
Erik Schnetter created an issue

Keep track of the volume that is masked out by CarpetMask, and take this volume into account when checking in CarpetReduce that the integral over the simulation domain equals the domain volume.

    as a stopgap measure (and maybe also afterwards): warn only once when the volumes begin and end to differ.

    Compiles but not further tested :-)

    Introduce a grid scalar CarpetReduce::excised_cells that tallies the volume that is excised from reduction operations, as is done e.g. in CarpetMask. This allows testing the correctness of the weight grid function for reduction operations in the presence of excision.

    I tried with the attached parfile (2 processors). The mask patch does not seem to fix the issue. My (completely ecidence less) suspicion would be that the issue are the outer boundaries (which are included by the reduction operation in CarpetReduce) and the ghost zones (which end up having weight 1 but are ignored by the reduction since it skips cctk_nghostzones points [at least did so in the git version where I looked at it last]). I get:

    The problem was that the excision region counted how much was excised before the boundary was marked, so that the boundary was effectively removed twice from the domain.

    Updated patch attached.

    Doesn't seem to fix it yet though it's a step in the right direction.

    actually it seems as if only a CCTK_ReduceLocalScalar was missing. mask.3.patch adds it. This passes my test file with 1 and 2 MPI processes and with small and large excised region.

    This works for me, at least with trunk. I tried simfactorie's qc-mclachlan.par file on Kraken today. And --- after fixing the number of metric_timelevels to avoid some low level Carpet assert (the one in ticket #163) --- it properly keeps track of the total volume for at least 2560 itrations or t=5M.

    Upon inspecting the timestamps of comment 3 (fixed, 2011-11-09) which is also the commit timestamp CarpetMask/ofb3ca7d192ff4 and the Maxwell release timestamp (2011-10-24) I am no longer surprised. This was not fixed in time for the release.

    This seems to happen again with the version of qc0-mclachlan.par proposed in #732 (which only adds more analysis routines). I observe the warning when running with 36 cores and 6 threads each but not when running on 1 core one thread or 2 cores 1 thread each.

    Yes. Unfortunately right now I get a SEGFAULT right after the error message. Currently I am doing a recompile from scratch.

    Even with the segfault I should be able to tell if this improves the situation.

    From the look of the patch and the fact that the error is MPI process number dependent the fix seems to be in the right direction.

    Does not seem to fix the issue though the number change slightly. I currently have

    The expected total volume before exclusion (which is "Simulation domain valume"+"Additional excised volume") is 432000.

    So it seems as if the error is due to some OpenMP issue since all runs using 1 thread per process find no difference whereas all runs that use 6 threads per process do find a difference.

    Please note that all runs (with or without the patch, with any number of processes and threads) abort shortly afterwards with a SEGFAULT exception:

    I confirm that my previous patch has no effect, since ghost zones were already correctly excluded.

    I see the OpenMP error; a global variable is modified by all patches simultaneously. A reduction clause is missing.

    The segfault seems to occur in an I/O statement; a certain "reserve" function fails. This looks like memory management. I don't know where string buffers are used -- this may be a timer issue. Raising level since this may be a blocker.

    New patch for OpenMP issue:

    I tracked down the commit that causes segfaults: hash 21272f1 "Carpet: Correct #ifdefs in CarpetSimpleMPIDatatypeLength" of Carpet. Going to bed now. I really have no idea how that one causes memory corruption though. Disabling QuasiLocalMeasures in the parfile removes the SEGFAULT. Disabling output for QuasiLocalMeasures' grid arrays and grid scalars does as well. Turning the CarpetIOScalar output for QLM on again, restores the SEGFAULT so it seems related to reduction of complex numbers??? The Info output for qlm_spin is not sufficient to restore the SEGFAULT.

    The commit mentioned above corrected the routine CarpetSimpleMPIDatatypeLength, but not the sibling routine CarpetSimpleMPIDatatype. Maybe this inconsistency leads to problems.

    If so, this patch may help:

    Roland, can you attach the parameter file that triggers this problem? The parameter file in the other bug report is only a patch, and I don't know against what to apply this patch. The patch has no path name, and its description does not mention a path name or thorn name either.

    Sure. It's the qc0-mclachlan.par file from CactusExamples/trunk (ie. our demo parfile), which I have just attached. The one proposed in #732 is now in trunk. Sorry for the confusion. I had applied all code patches against current master in Carpet.

    Applying only comment:22 does not help. There still is a segfault. The backtrace is:

    Erik: the data and all is on zwicky where I think you can at least read all my files in case you want a more in-depth look at it. The whole set of files is in /panfs/ds06/sxs/rhaas/simulations/qc0-mclachlantrunk .

    comment:19 seems to cure the initial issue (warnings about excised regions) by the way. We should likely close this ticket then and move the discussion about the reduction to a new ticket.

    Current master of Carpet (incl. 1bdb022a5dec73500986edb41ea1c8e67c6c5fc5 and 17845edc3640298238c742a51509be2423cd6373) shows neither of the issues anymore. These two commits I reviewed and they look ok. The others seem fine when just looking through them. All ok to be ported to the release branch I think.

    Ok to port into the release branch and close the ticket? I will run qc0-maclachlan.par to completion on zwicky to check that everything still works.
