[Trilinos-Users] miltivector::doExport and disabling isSameAs()

[John Moore]

I've been profiling my code with Vtune, and appears that %14 of the time is
spent in a call to Teuchos::reduceAll<int,int> invoked by
Tpetra::map::isSameAs(), which seems to be called by every call to
Tpetra::multivector->doExport()..

It seems that there should be a compile flag to turn off such checks. I
have the following configuration options set:

cmake \
  -D BUILD_SHARED_LIBS:BOOL=OFF \
  -D TPL_FIND_SHARED_LIBS:BOOL=OFF \
  -D Trilinos_LINK_SEARCH_START_STATIC:BOOL=ON \
  -D CMAKE_BUILD_TYPE:STRING=RELEASE \
  -D TPL_ENABLE_MPI:BOOL=ON \
  -D MPI_BASE_DIR="${MPI_ROOT}" \
  -D MPI_EXEC:FILEPATH="${MPI_BIN}/mpiexec" \
  -D MPI_Fortran_COMPILER:FILEPATH="${MPI_BIN}/mpif90" \
  -D MPI_CXX_COMPILER:FILEPATH="${MPI_BIN}/mpicxx" \
  -D MPI_C_COMPILER:FILEPATH="${MPI_BIN}/mpicc" \
  -D CMAKE_CXX_FLAGS:STRING="" \
  -D BLAS_LIBRARY_DIRS:FILEPATH=$MKL_LIB_DIRS \
  -D BLAS_LIBRARY_NAMES:STRING=$MKL_LIBS \
  -D LAPACK_LIBRARY_DIRS:FILEPATH=$MKL_LIB_DIRS \
  -D LAPACK_LIBRARY_NAMES:STRING=$MKL_LIBS \
  -D TPL_ENABLE_METIS:BOOL=ON \
  -D METIS_LIBRARY_DIRS:FILEPATH="${HOME}/local/metis-5.1.0/lib" \
  -D METIS_INCLUDE_DIRS:FILEPATH="${HOME}/local/metis-5.1.0/include" \
  -D METIS_LIBRARY_NAMES:STRING="metis" \
  -D TPL_ENABLE_ParMETIS:BOOL=ON \
  -D ParMETIS_LIBRARY_DIRS:FILEPATH="${HOME}/local/parmetis-4.0.3/lib" \
  -D ParMETIS_INCLUDE_DIRS:FILEPATH="${HOME}/local/parmetis-4.0.3/include" \
  -D ParMETIS_LIBRARY_NAMES:STRING="parmetis" \
  -D Trilinos_ENABLE_OpenMP:BOOL=OFF \
  -D TPL_ENABLE_Pthread:BOOL=ON \
  -D Trilinos_ENABLE_Tpetra:BOOL=ON \
  -D Trilinos_ENABLE_Ifpack2:BOOL=ON \
  -D Trilinos_ENABLE_Belos:BOOL=ON \
  -D Trilinos_ENABLE_Intrepid:BOOL=ON \
  -D Trilinos_ENABLE_Zoltan2:BOOL=ON \
  -D Tpetra_ENABLE_TESTS:BOOL=OFF \
  -D Trilinos_ENABLE_DEBUG:BOOL=OFF \
  -D DART_TESTING_TIMEOUT:STRING=100 \
  -D CMAKE_INSTALL_PREFIX:PATH=$PWD/../install_release \
  ${SOURCE_BASE}

Is there a flag that I'm forgetting about, or is it not possible to disable
this check?

Thank you,
John
