Significant Events FY 95
The Composable Systems Project developed and demonstrated several
prototype software tools this year, including Aesop, Unicon,
Venari/ML, and ChopShop.
The Aesop software architecture development system was demonstrated at
17th Conf. on Software Engineering (ICSE).
An initial prototype of Unicon, a system for defining heterogeneous
architectures, was installed at UniSys for evaluation and
experimentation. UniSys experimented with writing architectural
descriptions of the cruise control problem defined in paper "Candidate
Model Problems in Software Architecture" by M.Shaw, D.Garlan, R.Allen,
D.Klein, J.Ockerbloom, C. Scott, and M.Schumacher.
A detailed performance evaluation of Venari/ML transactional system
shows that their new concurrent garbage collection algorithm gives
comparable or better performance than C's explicit memory management
or competing automatic garbage collection algorithms.
ChopShop differs from other program-slicing tools in many ways. It
handles full ANSI C, programs that are 100 times larger (30,000 lines
instead of just 300), and does a modular analysis over the entire
program instead of just analysis of individual procedures. ChopShop
provides more accurate results than competing systems and displays
results in both textual and pictorial form.
