Maintenance modes of operation of a multiprocessing vector supercomputer system are disclosed. The modes allow diagnostics to run on a failed portion of the system while simultaneously allowing user tasks to run in a degraded performance mode. This is accomplished by assigning a processor or a group of processors to run diagnostics on an assigned portion of memory, while the operating system and user tasks are run in the remaining processors in the remaining portion of memory. In this manner, the diagnostics can isolate the problem without requiring complete shut down of the user task, while at the same time protecting the integrity of the operating system. The result is significantly reduced preventive maintenance down time, more efficient diagnosis of hardware failures, and a corresponding increase in user task run time. |
