Abstract
Tnis tnesis presents an automatic recovery design that
supports the fault-tolerant performance of a real-time,
distributed, multiple microcomputer system. The recovery
mechanism is stuctured to maintain real-time processing
applications where a record of previous computations is not
required and data loss is toleral)le during the period of
recovery. The automatic recovery technique employed is based
on system reinitialization in which the system is restored
to it's original initialized state and then restarted. T^^e
automatic recovery mechanism has been integrated with a
hierarchical, distributed operating system which supports a
mult ipro!?ramming" environment. A distinct address space for
each system process, that is preserved by the hardware's
explicit memory segmentation, in conjunction with the
independent kernel and user domains of the operating system
are used to facilitate dynamic relocation amon?: identical
processor modules. The result is a flexible environment that
supports the dynamic reconfiguration of processors and
memory during the period of reinitialization.
