This thesis presents extensions to an implementation of
a kernel in a real-time distributed operating system for a
microcomputer based multi-processor system.
The operating system, MCORTEX, is a 2 level,
hierarchically structured, loop free, system that permits
logical distribution of the kernel in the address space of
each process. The design is based on segmented address
spaces and per process stacks. Process synchronization is
achieved through sequencers and eventcounts. MCORTEX is
resident in the local memory of each microcomputer but
system data is maintained in shared global memory.
MCORTEX has been extended to include a system monitor
process which allows stopping the system to examine any
memory, shared or local, from any location. The system can
then be restarted without reinitializing each microcomputer.
This system particularly supports applications where
jobs are partitioned into a set of multiple interacting
asynchronous processes. The system is currently implemented
on INTEL 86/12A single-board computers.
