    Source-code Transformations for Efficient Reversibility
    (Georgia Institute of Technology, 1999) Perumalla, Kalyan S. ; Fujimoto, Richard M.
    An approach based on source-to-source compilation is presented for efficiently realizing reversibility of programs, in the context of the C language. The implementation of this approach in a portable "reverse C compiler" called rcc is described. The compiler takes arbitrary C functions as input, and renders them reversible, and, in addition, automatically generates their reverse functions. The system is sufficiently general to correctly handle complex data types and to handle complex control flow such as recursion and inter-mixing jump instructions. The compiler is designed to be general-purpose, to be used in any application requiring efficient reverse execution capability. A simple macro interface is used to help retarget the compiler to different application domains. As a case study, the application of rcc to optimistic parallel simulation is presented. Optimizations, such as "message-send slicing", are presented that help in reducing the overheads that may be added for achieving reversibility.

    MetaTeD --- A Meta Language for Modeling Telecommunication Networks
    (Georgia Institute of Technology, 1996) Perumalla, Kalyan S. ; Fujimoto, Richard M. ; Ogielski, Andrew T.
    TeD is a language designed mainly for modeling telecommunication networks. The TeD language specification is separated into two parts -- (1) a "meta" language (2) an "external" language. The meta language specification is concerned with the high-level description of the structural and behavioral interfaces of various network elements. The external language specification is concerned with the detailed low-level description of the implementation of the structure and behavior of the network elements. The meta language, called MetaTeD, is described in this document (An external language specification, with C++ as the external language, is described in a separate related document.).

    GTW++ -- An Object-oriented Interface in C++ to the Georgia Tech Time Warp System
    (Georgia Institute of Technology, 1996) Perumalla, Kalyan S. ; Fujimoto, Richard M.
    This document describes GTW++, an efficient object-oriented interface to the Georgia Tech Time Warp (GTW) parallel simulation system for shared memory multiprocessors. The interface, which is in C++, provides a clean and extensible set of abstractions for model developers wishing to use Time Warp as the parallel simulation paradigm. This interface delivers virtually the same performance as that of the C language interface to GTW. The object-oriented approach facilitates easily building higher-level interfaces, such as process-oriented views, over the basic GTW++ interface. GTW++ has been carefully designed so that almost identical interfaces can be supported for different parallel computing platforms, such as shared-memory machines and network of workstations, with appropriate underlying implementations for each platform. Furthermore, the GTW++ interface can be directly provided by the GTW kernel if and when the kernel itself is redesigned using an object-oriented approach.

    A C++ Instance of TeD
    (Georgia Institute of Technology, 1996) Perumalla, Kalyan S. ; Fujimoto, Richard M.
    TeD is a language designed mainly for modeling telecommunication networks. The TeD language specification is separated into two parts --- (1) a "meta" language (2) an "external" language. The meta language specification is concerned with the high--level description of the structural and behavioral interfaces of various network elements. The external language specification is concerned with the detailed low-level description of the implementation of the structure and behavior of the network elements. The meta language, called MetaTeD, is described in a separate related document. An external language specification, with C++ as the external language, is described in this document. A software support system for the development and parallel simulation of TeD models is also described.
