TpetraCore_MatrixMatrix_UnitTests Failed on CDash last night...
- CDash: https://testing.sandia.gov/cdash/index.php?project=Trilinos##Clean

@mhoemmen had a quick look at it for me, here's his assessment:
These tests work by reading parameters from a list stored in a file. It looks like for this particular test, the parameters insist on having exactly 4 MPI processes. However, the CMakeLists.txt file for the test (see tpetra/core/test/MatrixMatrix/CMakeLists.txt, top of file) doesn't specify a particular number of MPI processes, so CTest will just run with whatever number of processes it feels like using. p=0: *** Caught standard std::exception of type 'std::runtime_error' :
Test requires exactly 4 MPI ranks. [FAILED] (0.106 sec) Tpetra_MatMat_double_int_int_Kokkos_Compat_KokkosSerialWrapperNode_operations_test_UnitTest Location: . . . /SERIAL_Release_gcc_4.9.3__DEV/Trilinos/packages/tpetra/core/test/MatrixMatrix/MatrixMatrix_UnitTests.cpp:767
