Abstract
Multi-Staging for Object-Oriented Language
Tamer Mohamed Abd El-Lateef
Multi-staging programming (MSP) is one of the discerning approaches
that emerged to improve software performance. It minimizes runtime overhead
caused by abstraction mechanisms like functions, classes and recursion. It
stages the program execution by postponing the evaluation of performancecostly
code segments to a later point in which it can be reused. It originated in
functional languages and currently, it targets object-oriented languages (like
Java and C#). For this reason, the thesis introduces a multi-staging based
compiler called Mint. This compiler is a Java language compiler but in the dress
of multi-staging programming. It combines the advantages of multi-staging
programming with those of Java as an object-oriented language.
An increase in the number of MSP implementations is expected in the
future. This calls for the need of a reliable way to compare those different
implementations and assess their efficiency in software performance
improvement. For this purpose, the thesis proposes a benchmark that includes a
variety of classic and new example applications. Each application is
implemented in Mint (MSP Java implementation) and Metaphor (MSP C#
implementation). The results of the two implementations are compared and
assessed.
With the increasing complexity of a software application, it becomes
inconvenient to entirely depend on the programmer sense in applying MSP to
the application. Here comes the need for a clear defined approach or
methodology in order to apply MSP in an accurate and systematic way. The
thesis fulfils this need with a performance enhancement approach. This
approach is represented by a set of steps for the programmer to follow
throughout the process of applying MSP to a software application regardless of
the application field and complexity. In other words, the programmer does not
have to be an expert in the application to apply MSP.
In order to illustrate and assess the efficiency of the proposed approach, it
is applied to a case study. The case study represents the RSA encryption
technique. The results of the case study prove the efficiency of the approach in
boosting the application performance, and, in turn, this emphasizes the positive
effect of MSP on software performance especially complex applications.
