 | Our initial research since the inception of this project has established the viability and effectiveness of each of the novel aspects of our approach to massively concurrent computing viz. specialized communications substrate, threads based programming, semi-automatic domain specific parallelization, and failure resilient computing. Experiences with a few, but nonetheless representative, classes of applications has demonstrated the efficacy of our prototype systems, and have established the justifications for building robust production ... |

| This project deals with an experimental approach to developing enabling technology for the efficient support of collaborative simulation engines on heterogeneous networked platforms. The goal is to achieve collaborative operations of two kinds: cooperative operations between distinct but neighboring numerical solvers (simulation engines), and also collaboration between users who interact with neighboring solvers during model development, experimentation and production mode operation. To deliver efficient runtime support, we propose an architecture ... |

| This research is motivated by emerging virtual collaboratories, distributed multimedia, and scalable distributed computing applications on modern heterogeneous networks of machines. It has had a humble origin, namely, a simple threads system (Ariadne) that was developed in our software laboratory (PacsLab) at Purdue. The Ariadne project has since expanded in scope, matured, and won recognition as a powerful supporting infrastructure for timer-enhanced multithreaded distributed computing. This is mainly due to ... |

|
| We investigate methodologies and tools for the deployment of massively parallel simulation-oriented computations on a variety of hardware platforms, particularly heterogeneous networks of workstations. The underlying ideas are based in part on the prize-winning performance of the EcliPSe parallel simulation toolkit in the 1992 Gordon Bell Prize competition. The primary motivation is that the replication of computations involving statistical sampling be deployable through a transparent use of sequential codes. A ... |

|
| An application-independent visualization interaction system is proposed with potential for application-binding at any stage of the modeling process. Advantages of this approach include ease of use, flexibility, code reuse, and modularity. Our design ideas are manifest in the DiSplay system, a graphical user interaction and display library which can be used with any parallel software. We outline its use in the dynamic display of results from computations in queueing simulations, ... |
