make a significant contribution to industries that utilize this

cluster, a highly cost-effective and scalable parallel computer
model. However, realizing on such a platform a high performance virtual
machine implementation tolerant to hardware and software faults, and
having efficient memory utilization, presents many challenging research
issues. This project will address these issues by extending a highly
efficient and extensible Java implementation to be aware of its cluster
environment.

Extending a family of garbage collectors. Garbage collection is a key component in the automatic management of storage in computer systems. It is an essential property of modern programming systems that frees the programmer from a significant error-prone task.

Using our novel construction methodology, we have jointly produced a family of collection algorithms that are significantly simpler and ....Extending a family of garbage collectors. Garbage collection is a key component in the automatic management of storage in computer systems. It is an essential property of modern programming systems that frees the programmer from a significant error-prone task. Our interest is in garbage collection in distributed systems involving a number of networked computers. Using our novel construction methodology, we have jointly produced a family of collection algorithms that are significantly simpler and more efficient than previous work. Here we wish to extend this family to operate effectively in a specific architecture increasingly favoured by many modern distributed high-performance computing systems.Read moreRead less

Adaptive and Integrated Resource Allocation. By leveraging progress in communication technologies, adaptive and integrated optimization systems will open innovative application areas critical to Australia, yet outside the scope of existing optimization technology. For instance, they will dispatch and reallocate ambulances in real time, help contain pandemics, allocate resources dynamically to extinguish bushfires, and assist in failure recovery of energy infrastrutures. These systems will also s ....Adaptive and Integrated Resource Allocation. By leveraging progress in communication technologies, adaptive and integrated optimization systems will open innovative application areas critical to Australia, yet outside the scope of existing optimization technology. For instance, they will dispatch and reallocate ambulances in real time, help contain pandemics, allocate resources dynamically to extinguish bushfires, and assist in failure recovery of energy infrastrutures. These systems will also solve existing logistics and manufacturing applications better, making these industries more effective and reactive. The project also aims at establishing a center of excellence in optimization in Melbourne with an international reputation in research, teaching, and industrial collaboration.Read moreRead less

The outcomes of this project will provide generic solutions to many Australia-based industries, including telecommunication, network management, sensor networks, automotive and instrumentation/measurement, where embedded systems are ubiquitously used. Therefore, this project will significantly contribute to the Priority Area (Frontier Technologies for Building and Transforming Australian Industries), hence fits into its Priority Goal: Frontier Technologies.Read moreRead less
Compiler-Directed Code Tiling for Higher Program Performance and Predictability on Multi-Level Memory Hierarchies. Programming languages invariably induce a perception of memory as being flat, whereas actual computers are being equipped increasingly with deep memory hierarchies to overcome the ever-widening performance gap between processors and memories. This mismatch can result in low locality of reference and poor performance. This project will develop a new array layout transformation, calle ....Compiler-Directed Code Tiling for Higher Program Performance and Predictability on Multi-Level Memory Hierarchies. Programming languages invariably induce a perception of memory as being flat, whereas actual computers are being equipped increasingly with deep memory hierarchies to overcome the ever-widening performance gap between processors and memories. This mismatch can result in low locality of reference and poor performance. This project will develop a new array layout transformation, called data tiling, used in tandem with loop tiling to achieve significantly improved performance gains (and predictability) for array-dominated applications on multi-level memory hierarchies. We will explore this joint restructuring to obtain higher performance and predictability for whole programs, kernel libraries, iterative stencil codes and embedded applications.

A safe and efficient multi-language component framework based on dynamic compilation. Components are a versatile mechanism for the construction of extendible systems and for improved code reusability. Emerging environments like Microsoft's .NET support the interaction of components written in different programming languages. To date, such systems do not adequately isolate components which therefore must trust each other. This is unacceptable for components loaded across the Internet. We will dev ....A safe and efficient multi-language component framework based on dynamic compilation. Components are a versatile mechanism for the construction of extendible systems and for improved code reusability. Emerging environments like Microsoft's .NET support the interaction of components written in different programming languages. To date, such systems do not adequately isolate components which therefore must trust each other. This is unacceptable for components loaded across the Internet. We will develop a framework for secure execution of component software, based on hardware-enforced protection domains. To minimize the resulting runtime overheads we will provide a component model with lightweight context switching. A novel typed intermediate language and dynamic compilation techniques will offer complementary optimisations.

Reasoning about Rational Agents from a Programming Languages Perspective. Rational agents are complex system components inspired by models of rationality, in which beliefs, desires and intentions are represented explicitly. Intelligent agents are fast becoming mainstream and have wide-ranging industrial application. However, a serious obstacle to the deployment of rational agents is a lack of understanding of how to design and reason about agents to provide performance and correctness guarantees ....Reasoning about Rational Agents from a Programming Languages Perspective. Rational agents are complex system components inspired by models of rationality, in which beliefs, desires and intentions are represented explicitly. Intelligent agents are fast becoming mainstream and have wide-ranging industrial application. However, a serious obstacle to the deployment of rational agents is a lack of understanding of how to design and reason about agents to provide performance and correctness guarantees. This project will investigate extensions to intelligent agent architectures and develop tools for reasoning about complex systems built using those architectures. This will not only enable reliable prediction of performance, but contribute to a general methodology for intelligent agent design.
