Hello, I am running an application code which works with 4, 8 and 18 processes but crashes with 16 processes. I have used MPICH2 and MVAPICH2 (both adhered to the MPI 3.0 standard) and both cause the same problem. I get the following error message:
[12]PETSC ERROR: MatSetValues_MPIAIJ() line 564 in src/mat/impls/aij/mpi/mpiaij.c [12]PETSC ERROR: MatAssemblyEnd_MPIAIJ() line 680 in src/mat/impls/aij/mpi/mpiaij.c [12]PETSC ERROR: MatAssemblyEnd() line 4879 in src/mat/interface/matrix.c [12] --> Error in "MatAssemblyEnd()". [12] --> Code: 63 However, I do not get this using the Intel MPI (which adheres to the MPI 2.0 standard) library. Any help will be greatly appreciated.
