| mpi-type-mismatch |
| ================= |
| |
| This check verifies if buffer type and MPI (Message Passing Interface) datatype |
| pairs match for used MPI functions. All MPI datatypes defined by the MPI |
| standard (3.1) are verified by this check. User defined typedefs, custom MPI |
| datatypes and null pointer constants are skipped, in the course of verification. |
| |
| Example: |
| |
| .. code-block:: c++ |
| |
| // In this case, the buffer type matches MPI datatype. |
| char buf; |
| MPI_Send(&buf, 1, MPI_CHAR, 0, 0, MPI_COMM_WORLD); |
| |
| // In the following case, the buffer type does not match MPI datatype. |
| int buf; |
| MPI_Send(&buf, 1, MPI_CHAR, 0, 0, MPI_COMM_WORLD); |
