As far as I know, FAA's endeavor to implement the next generation
distributed, fault-tolerant, real-time air traffic control system also
uses shared memory extensively. Each workstation reserves an area to
store runtime-adaptable processor Id, facility Id, rank info., and so on.
The area is shared among all local operating units. Some of the info
in shared memory is required for message passing (header). Some others
can be modified by a global monitor on certain occasions (such as
system failure and re-configuration).
I don't see any problem with the design.
