Problem finding library for MultiApps

[no...@berkeley.edu]

Hi all,

I'm trying to run a simulation with several MultiApps - Okapi (OpenMC wrapped as a MooseApp), Buffalo (surrogate for BISON), and MOON (Nek5000 wrapped as a MooseApp). The MasterApp is Okapi (performs a dummy solve and only acts to transfer data between the three MultiApps). I've gotten this setup to run correctly for the Okapi-Buffalo situation, but once I add in MOON, I'm running into problems with finding the libmoon-dbg.so library. Specifically, I get the following error message:

*** ERROR ***

Cannot open library: /homes/anovak/projects/moon/lib/libmoon-dbg.so.0

The library is there:

anovak@nash:~/projects/moon/lib$ ls

libmoon-dbg.la  libmoon-dbg.so.0.0.0 libmoon-opt.so

libmoon-dbg.so  libmoon-dbg.txt libmoon-opt.so.0

libmoon-dbg.so.0  libmoon-opt.la libmoon-opt.so.0.0.0

 and to be sure I put it in LD_LIBRARY_PATH:

anovak@nash:~/projects/okapimcs $ echo $LD_LIBRARY_PATH

/homes/anovak/projects/moon/lib:/homes/anovak/projects/openmc/build/lib:/soft/apps/packages/climate/mpich/3.2/gcc-6.2.0/lib:/soft/apps/packages/gcc/gcc-6.2.0/lib64:/soft/apps/packages/climate/hdf5/1.8.16-parallel/gcc-6.2.0/lib

In my Master App input file, the MultiApp section looks like:

[MultiApps]

  [./bison]

    type = TransientMultiApp

    app_type = BuffaloApp

    positions = '0 0 0'

    input_files = 'bison.i'

    execute_on = timestep_begin

    library_path = /homes/anovak/projects/buffalo/lib

  [../]

  [./openmc]

    type = TransientMultiApp

    app_type = OkapiMCSApp

    positions = '0 0 0'

    input_files = 'openmc.i'

    execute_on = timestep_begin

  [../]

  [./nek]

    type = TransientMultiApp

    app_type = MoonApp

    positions = '0 0 0'

    input_files = 'nek.i'

    execute_on = timestep_begin

    library_path = /homes/anovak/projects/moon/lib

  [../]

I'm not sure if this can be answered here because the problem might be very specific to MOON, but I thought I'd ask to see if there are any other things I might be missing. I did also try the reverse, where MOON acts as the MasterApp and facilitates data transfer between Okapi, Buffalo, and MOON, but instead I got the following error (and this library is also there, so could be a common-cause failure...):

*** ERROR ***

Cannot open library: /homes/anovak/projects/moose/modules/module_loader/lib/libmodule_loader_with-dbg.so.0

One thing that might be causing the problem is that MOON and Okapi/Buffalo use different MOOSE_DIRs - forcing MOOSE_DIR to be the same for all of them gives me errors building the MOON executable, though. 

Thanks very much, and have a good weekend!

I don't know about the rest: but you definitely can't have two versions of MOOSE running around. You need to check out a version of MOOSE in its own directory and set MOOSE_DIR to that and build all three applications using it (resolving any compile issues).

Thanks, Derek, I believe that building all three Apps with the same MOOSE_DIR solved the problem (just had to resolve a few compiling issues with inclusion of header files)!

Nice April - Looks like you are basically doing CASL at this point. You need a raise!

This is (mostly) fun, I'd do it for free!
