A multiprocessor configuration includes a plurality of processing groups connected to form both a first and second communication path, and an interpath connection connecting the first and second communication paths. The first and second communication paths and the interpath connection provide allow communication between processors in different processing groups even if one processing group fails and, thus, creates a discontinuity in both the first and second communication paths. One or more processors in each processing group may be operable to perform fault recovery in response to a detected failure in another processing group.
