13.6.1. Error Handlers

PreviousUpNext
Up: Error Handling Next: Error Classes Previous: Error Handling

Errors occurring during calls to routines that create MPI windows (e.g., MPI_WIN_CREATE) cause an error to be raised on the communicator provided to that procedure call. All other RMA calls have an input window argument on which errors will be raised if they occur.

The error handler MPI_ERRORS_ARE_FATAL is associated with the window during its creation. Users may change this default by explicitly associating a new error handler with the window (see Section Error Handling).
