Finding concurrency bugs in multithreaded software. This project aims to develop sound and practical techniques for detecting and eliminating concurrency bugs for object-oriented languages like Java, enabled by a new model for concurrent effects. The expected outcome is a novel technology that will significantly improve the safety, productivity and efficiency of large-scale concurrent programming.

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.

Soundness-guided security analysis for android applications. This project aims to develop a soundness-guided programme analysis to mitigate security threats caused by reflection and dynamic class loading in Android apps, without compromising precision and scalability. Both dynamic code update techniques are widely used in benign and malware apps, but state-of-the-art malware analysis tools ignore or mishandle them, missing security threats and vulnerabilities. The resulting open-source security ....Soundness-guided security analysis for android applications. This project aims to develop a soundness-guided programme analysis to mitigate security threats caused by reflection and dynamic class loading in Android apps, without compromising precision and scalability. Both dynamic code update techniques are widely used in benign and malware apps, but state-of-the-art malware analysis tools ignore or mishandle them, missing security threats and vulnerabilities. The resulting open-source security analysis tool will allow software industries and enterprises (from national security, finance, banking to healthcare, retail, telecommunications) to test their mobile software effectively for code defects or security threats early at software development time at significantly reduced cost.Read moreRead less
Micro Compilers: An Extensible Compiler Architecture for Increased Flexibility and Safety.

Programming languages specialised to a particular application domain can cut software development costs and reduce programming errors. Unfortunately, most application domains cannot sustain the costly development and maintenance of the specialised compilers required to implement specialised languages. We address this problem by introducing a novel customisable compiler architecture that can be adapted to specialised languages and other special-purpose compiler requirements. Customisable compilers are especially important to a country like Australia that has only limited resources for special purpose developments. Moreover, we will train students at undergraduate and postgraduate level in the area of programming languages and compilers.Read moreRead less
Portable High-Performance Computing Based on Flattening and Fusion. We aim at simplifying the development and improving the portability of computing intensive applications, such as those from computational science and engineering, which are of growing scientific and economic relevance (e.g., drug synthesis, virtual wind tunnel, and geologic surveys).

We aim at simplifying the development and improving the portability of computing intensive applications, such as those from computational science and engineering, which are of growing scientific and economic relevance (e.g., drug synthesis, virtual wind tunnel, and geologic surveys). Our focus is on achieving portable high-performance for a particularly expressive high-level notation supporting irregular algorithms (like sparse matrices and hierarchical N-body codes). We will develop a set of program transformations and integrate them into a compiler implementing an aggressive fusion strategy optimising for the memory hierarchy. We do not propose a new programming language, but work within an existing one.Read moreRead less

This project aims to build secure defences against code-reuse attacks in large-scale C++ applications with millions of lines of code, by enforcing control flow integrity with modular pointer analysis. The state-of-the-art mitigation techniques that are deployed in mainstream computer operating systems can all be bypassed by advanced code-reuse attacks, resulting in security exploits in all major web browsers.

This project aims to build secure defences against code-reuse attacks in large-scale C++ applications with millions of lines of code, by enforcing control flow integrity with modular pointer analysis. The state-of-the-art mitigation techniques that are deployed in mainstream computer operating systems can all be bypassed by advanced code-reuse attacks, resulting in security exploits in all major web browsers. The outcomes of this project will be an exploit mitigation technology and an open-source tool that can significantly raise the bar against advanced code-reuse attacks, thereby providing a foundation for eliminating such security threats.Read moreRead less
