Description

As shown in this query the test:

• MueLu_UnitTestsTpetra_MPI_4

is failing in the builds:

• Trilinos-atdm-waterman-cuda-9.2-opt
• Trilinos-atdm-waterman-cuda-9.2-debug

In the cdash results for yesterday we can see that this test on cuda builds is taking 6+ minutes to complete and on non-cuda builds completes in less than 90 sec. Waterman is the only platform where it hit the timeout but others are very close. for example, one build on ride took 9:49 yesterday.

Steps to Reproduce

One should be able to reproduce this failure on the machine waterman as described in:

• https://github.com/trilinos/Trilinos/blob/develop/cmake/std/atdm/README.md

More specifically, the commands given for the system waterman are provided at:

• https://github.com/trilinos/Trilinos/blob/develop/cmake/std/atdm/README.md#waterman

The exact commands to reproduce this issue should be:

$ cd <some_build_dir>/

$ source $TRILINOS_DIR/cmake/std/atdm/load-env.sh cuda-debug

$ cmake \
  -GNinja \
  -DTrilinos_CONFIGURE_OPTIONS_FILE:STRING=cmake/std/atdm/ATDMDevEnv.cmake \
  -DTrilinos_ENABLE_TESTS=ON -DTrilinos_ENABLE_MueLu=ON \
  $TRILINOS_DIR

$ make NP=20

$ bsub -x -Is -n 20 ctest -j20
