    • 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.
    • 公开了多处理向量超级计算机系统的维护操作模式。 这些模式允许诊断在系统的故障部分运行,同时允许用户任务以降级的性能模式运行。 这通过分配处理器或一组处理器来在分配的存储器部分上运行诊断来实现,而操作系统和用户任务在剩余部分存储器中的其余处理器中运行。 以这种方式,诊断可以隔离问题而不需要完全关闭用户任务,同时保护操作系统的完整性。 结果是显着减少了预防性维护停机时间,更有效地诊断硬件故障,并相应增加了用户任务运行时间。
