Seg Fault when trying to use new MueLu preconditioners for Enthalpy problems

[mperego]

I get a segmentation fault when using the new MueLu settings provided by Ray Tuminaro for the Humboldt problem. I tried different settings, below is the error for P1semR1transP2const:

I didn't get much info running dbg. To reproduce the error, build branch https://github.com/sandialabs/Albany/tree/enthalpy_muelu and run the Enthalpy tests: ctest -R Enthalpy_Humboldt_MueLu

@mperego I have an Albany executable on Perlmutter, but that's probably not the easiest platform to debug on. Is there another machine you'd suggest I build on?

[mperego]

Thanks @jhux2. You could use blake. We have scripts for building Trilinos and Albany. I think you can use the gcc modules blake_gcc_modules_submit.sh and cmake scripts, do-cmake-trilinos-gcc-serial, do-cmake-albany-serial. -- I got the error with gcc compiler. @jewatkins do you have better advise?

[jewatkins]

blake is probably the best option right now. The gcc build is a debug build so it will run slow but it might give you more information. You can use the binary directly: /home/projects/albany/nightlyCDashAlbanyBlake/build-gcc/AlbBuildSerialGccNoWarn/src/Albany or use the trilinos install /home/projects/albany/nightlyCDashTrilinosBlake/build-gcc/TrilinosSerialInstallGccNoWarn/

[jhux2]

I've run the Humboldt test that's on the main branch, just as a sanity check. This uses the executable that @jewatkins pointed to. Right after the stacked timer output, which I assume comes the end of the simulation, there are a few errors. Are these to be expected?

|   |   Phalanx::SortAndOrderEvaluators: 8.958e-06 - 0.125643% [5]

[jewatkins]

Yes looks like it: https://sems-cdash-son.sandia.gov/cdash/test/3060119 We should probably look into why that's happening. The final result looks correct though.

[mperego]

@jhux2 any updates on this?

[jhux2]

@mperego Sorry, I've not looked at this in a while. I'll pick this back up.

[jhux2]

@mperego I updated your branch with master and am seeing the following error. Has parsing of ice_thickness changed somehow?

@jhux2, we cleaned a bit the code. Please remove these lines:

    Required Fields: [ice_thickness]
    Required Basal Fields: [ice_thickness]

Element Shape: Wedge

Thanks, @mperego. Another error, I guess masked by the first:

@jhux2 I guess you merged with master before #888 got merged. If so, you need to put back Element Shape: Wedge

Let me know if this is not the issue

[jhux2]

@mperego That seems to have fixed it, I'm now back to the original error you reported. Thanks.

[jhux2]

@mperego Here's a quick update. MueLu's setup is recursing until it exhausts stack memory, and one of the processes seg faults. I'm sifting through factory dependency information at the moment to see what's going wrong.

[mperego]

@jhux2 thanks for looking into that! It doesn't sound fun..

[mperego]

@jhux2 are there any updates on this issue?

[mperego]

Hi @jhux, there have been some changes in Albany that needs to be merged in this branch. A few additional changes are needed in the input files as well. Let me know when you plan to look into this and I'll do the merge and fix the input files.
