As I know the idea of active object comes from J. Gutknecht. In his
group exciting system and applications have been developed. The thesis
of Pieter Mueller describes the lowest level of the system with process
creation and management on multi core hardware. Patrik Reali has written
a compiler which used the multi threading. Then the Bluebottle system
came from T. Frey - a big collection of applications also with
fundamental features for example sequencers in the space of graphical
objects and there properties. Together with the Fox compiler from F.
Friedrich the system has developed to the A2 system which even contains
a system of active cells where the FPGA hardware is also a part. In the
recent time F. Negele developed a multi threading system without locks.
All of that is truly worth understanding.
I hope I didn't forget anybody and when then I'm sorry.
