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.

Georgia Tech Time Warp (GTW Version 3.1) Programmer's Manual for Distributed Network of Workstations

(Georgia Institute of Technology, 1997) Fujimoto, Richard M. ; Das, Samir Ranjan ; Panesar, Kiran S. ; Hybinette, Maria ; Carothers, Christopher D.

This manual gives an introduction to writing parallel discrete event simulation programs for the Georgia Tech Time Warp (GTW) system (version 3.1). Time Warp is a synchronization mechanism for parallel discrete event simulation programs. GTW is a Time Warp simulation kernel implemented on distributed network of uniprocessor and shared memory multiprocessor machines.
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.).
Distributed Laboratories: A Research Proposal

(Georgia Institute of Technology, 1996) Schwan, Karsten ; Ahamad, Mustaque ; Hudson, Scott E. ; Limb, J. O. (John O.) ; Ammar, Mostafa H. ; Ezquerra, Norberto F. ; Mukherjee, Amarnath ; Potts, Colin ; Ramachandran, Umakishore ; Zegura, Ellen W. ; Fujimoto, Richard M.

The continuing merger of computer and communication technologies is leading to a new computing/communications infrastructure of unprecedented magnitude, enabling new applications with broad economic and social impact. Yet, such applications pose major challenges to researchers in Computer Science and in application domains. The topic of the proposed research program is the realization of Distributed Laboratories, where individuals can interact with each other, and more importantly, with powerful, distributed computational tools as readily as if all were located in a single site. Our intent is to permit scientists, engineers, and managers at geographically distinct locations (including individuals 'tele-commuting' from home) to combine their expertise in solving shared problems, by allowing them to simultaneously view, interact with, and steer sophisticated computations executing on high performance distributed computing platforms.
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.
