Family History
Opal is a descendant of a number of object-oriented distributed
systems built at UW during the 1980s. Following are some
references to some of those systems.
- E. Jul, H. Levy, N. Hutchinson, A. Black.
Fine-Grained Mobility in the Emerald
System. ACM Trans. on Computer Systems 6(1), February 1988.
(Emerald is a distributed object-oriented language and system supporting
a single, logical, distributed, object address space. It was the first
system with on-the-fly object mobility. Protection is guaranteed by
the language and compiler.)
- J. Chase, F. Amador, E. Lazowska, H. Levy, R. Littlefield.
The Amber System: Parallel Programming on a Network
of Multiprocessors. Proc. of the 12th ACM Symp. on Operating
Systems Principles, December 1989. (Amber is a distributed object-oriented
system, based on C++, for writing parallel programs that execute on
a local-area network; Amber uses a single shared distributed address
space above which C++ objects are supported.)
