11. Extending the real time specification for Java for cache coherent NUMA architectures

Abstract

The recent past has seen single processing systems becoming obsolete and multiprocessor systems taking over as the architecture of choice. More scalable architectures are being introduced to keep up with the ever increasing computational requirements. Inevitably the software industry has to keep up and provide tools which would allow easy development of parallel applications on these complex architectures. Programming languages unable to support these architectures will become obsolete and new languages will be developed designed to serve the purpose. Existing languages that have the potential of coping with such architectures will be extended. Java is an object oriented language which provides features like platform independence and concurrency by design. It is supported on a wide range of computational devices starting from high performance computing servers to small hand held mobiles. This makes Java a very popular language, with a large pool of programmers. Therefore, it is not strange to see Java being extended for different multiprocessor and distributed systems. The Real-Time Specification for Java (RTSJ) was introduced as a high level platform for developing real-time applications. It has been gaining popularity since its inception and is being increasingly used for real time development. The recent version of RTSJ (i.e. RTSJ~1.1) has included some support for multiprocessors. The changes that have been introduced are largely related to the scheduling and dispatching of threads in symmetric multiprocessors. It is assumed that the memory allocations will not affect the timing properties of the system and it will be accessed uniformly. This thesis argues that these changes are not enough to support shared memory multiprocessors on RTSJ; and the following issues need to be addressed: \begin{itemize} \item In shared memory multiprocessors, uniform memory access (UMA) systems are not scalable and will be replaced by cache coherent non-uniform memory access (cc-NUMA) systems. Locality can largely affect the performance of applications and cause unpredictable delays in real-time applications on cc-NUMA systems. These delays are caused by the distributed memory layout in cc-NUMA and can be reduced by giving applications more control and visibility into the allocation policies of threads and memory. \item The increased computational power of multiprocessors encourages the platform to be shared by multiple applications. In such an environment, real-time applications require temporal guarantees from the platform to meet their timing requirements. \end{itemize} The key contribution of this thesis is to extend the programming model of RTSJ to provide programmers with locality constraints. Existing support in RTSJ for locality is shown to be very limited and a new locality model is presented which enables programmers to develop portable applications. Applications are divided into multiple partitions and temporal guarantees are provided to partitions allowing them to be analyzed in isolation from the rest of the system. A prototype of the aforementioned model is implemented and tested. A series of experiments are conducted to prove the effectiveness of the model. In particular, the effect of locality is highlighted by performance measuring in a multithreaded environment.

29. Joint detection and tracking of multi-objects from image observation under unknown background dynamics

Author

MALIK, HASEEB and MALIK, HASEEB

Abstract

This dissertation applies two independent information fusion frameworks to jointly detect and track multi-objects in an image sequence using random sets (RFS). The first framework fuses information by treating underlying observation and associated models as unambiguous processes. The second framework allows integration of ambiguous information with conventional unambiguous information using a novel approach based on the parametric statistics. A major contribution lies in treating the camera dynamics as completely unknown throughout the dissertation. Furthermore as an approximate solution to tre Bayesian filtering equations, the extended target track-before detect PHD filter as well as multi-sensor CPHD filter are derived in a mathematically rigorous manner. Finally both frameworks are successfully applied to multi-object tracking in image sequence. Other contributions of this dissertations include but not limited to: • A Novel relative velocity based approach, termed sum of relative velocity magnitude (SRVM) to detect moving objects. • A novel 2D to 3D and vice versa velocity transformation for state estimation within image processing phase of tracking. • A SRVM intensity image based visualization and detection approach for multiple moving objects. The final two algorithms include 1. Fusion of unambiguous information using random sets and associated track before detect PHD filter for extended multi-targets. 2. Fusion of ambiguous information using random sets and associated multi-sensor CPHD filter with assumed known measurement to object association (MOA) (see chapter 1 for details on MOA).
