 Priority:  minor                  |   Milestone:                     
Component:  EinsteinToolkit thorn  |     Version:  development version
 Keywords:  Llama CarpetInterp2    |  
-----------------------------------+----------------------------------------
 The test parameter file
 arrangements/Llama/LlamaWaveToy/test/llamawavetoy_7patch.par fails with an
 assertion when run on 2 processes, but runs without error on 1 process.
 Note that this is not necessarily a regression, as the test is new.  The
 error is

     WARNING[L1,P0] (CarpetInterp2): Array access out of bounds
 *this=fasterp_src_loc_t{
     ...
     Could not determine valid interpolation stencil for point 8359 on map
 0, refinement level 0, component 0

 The equivalent test with the 6-patch system works on both 1 and 2
 processes.  The full output, including bbox output, is attached.  To
 reproduce, run

     sim create-run llamawavetoy_7patch --parfile
 arrangements/Llama/LlamaWaveToy/test/llamawavetoy_7patch.par --procs 2
 --num-threads 1
