Bug Report

@trilinos/tpetra

Description

Line 1335 of Tpetra_Details_FixedHashTable_def.hpp produces a segfault when running with no UVM by default. An old comment on line 1313 suggests this function assumes UVM.

Steps to Reproduce

  1. Configure Tpetra for Cuda with -DKokkos_ENABLE_CUDA_UVM=OFF and -DTpetra_ENABLE_CUDA_UVM=OFF
  2. Build
  3. Run ctest -R "TpetraCore_Map_OneToOne_MPI_2"

The following tests are believed to fail (at least in part) due to this issue:

  • TpetraCore_Map_Bug2431_MPI_4
  • TpetraCore_Map_Bug6051_MPI_2
  • TpetraCore_Map_OneToOne_MPI_2
  • TpetraCore_Map_Bug5822_2_MPI_2
  • TpetraCore_Map_ExportTest_Bug5882_MPI_2

Suspect these tests may also be affected by this issue:

  • TpetraCore_FECrs_MatrixMatrix_UnitTests_MPI_4
  • TpetraCore_FECrsGraph_UnitTests_MPI_4
  • TpetraCore_MatrixMarket_Tpetra_CrsGraph_InOutTest_MPI_4
  • TpetraCore_MatrixMarket_Tpetra_CrsMatrix_InOutTest_MPI_4
  • TpetraCore_MatrixMarket_Operator_Test_MPI_4
