Enhancing Programs Behind the Scenes

Abstract:
Common program enhancement tasks include adding capabilities such as
distribution, persistence, and logging to the core functionality of a
computer program. Traditionally, program enhancement has entailed having
to modify the source code of a program explicitly. Our research explores
an alternative approach that adds new capabilities to existing programs
transparently, without affecting the maintained version of their source
code. This presentation will cover two domains of such transparent
program enhancement: enabling safe distribution of Java programs and
introducing optimizing transformations in object-oriented programs.

The first domain is concerned with the problem of evolving a centralized
program into a distributed program using language tools, aiming to
enable distributed programming with a programming model/semantics that
closely resembles centralized programming. This presentation will
describe J-Orchestra, our flagship language tool for distributed
computing. J-Orchestra (http://www.j-orchestra.org) is an automatic
partitioning system that takes as input a Java application in bytecode
format and transforms it into a distributed application, running across
multiple standard JVMs.

The other domain is concerned with introducing optimizing
transformations in object-oriented programs without modifying their
source code by means of binary refactoring, a novel software engineering
technique. The raison d'être of binary refactoring is not that current
programs need more optimization but that programmers already apply code
structure transformations for performance reasons, yet these
transformations unnecessarily pollute the source code and affect its
maintainability. With binary refactoring all such transformations can be
codified and applied through a refactoring browser without affecting the
application source code.

Biography
Eli Tilevich is a Ph.D. candidate in Computer Science at the Georgia
Institute of Technology working with Dr. Yannis Smaragdakis. He obtained
a B.A. Summa Cum Laude from Pace University and an M.S. from NYU and
worked for several years in New York as a software developer. His
research interests are on the systems/languages end of Software
Engineering, spanning distributed systems, object-oriented programming,
and software technology.
