Mobile platforms have become ubiquitous in our society; however, classical benchmarks have not kept up with their growth. When not entirely incompatible, current benchmarking techniques often provide very little useful information about...
In recent years, studies have shown that independent/sparse components of local windows of natural images resemble the receptive fields of cells in the early stages of the mammalian visual pathway. However, the role of the independence...
When considering computer processors, there is a trade-off between performance and power; improved performance does not typically come without an increase in power. Similarly, the reduction of power often times means a reduction in...
The Internet provides a general communication environment for distributed resource sharing. XML has become a key technology for information representation and exchange on the Internet, increasing the opportunity for integration of the...
Message Passing Interface (MPI) is broadly used in parallel applications. As High Performance Computing (HPC) systems become massively parallel, the efficiency of communication among processes has become more critical. Since the birth of...
This thesis is composed of two parts. Part one is on Appearance-Based Classification and Recognition Using Spectral Histogram Representations. We present a unified method for appearance-based applications including texture classification...
The presence of data dependences between statements in a loop iteration space imposes strict constraints on statement order and loop restructuring when preserving program semantics. A compiler determines the safe partial ordering of...
As we reach the limits of single-core computing, we are promised more and more cores in our systems. Modern architectures include many performance counters per core, but few or no inter-core counters. In fact, performance counters were...
In this dissertation a unified compiler framework for program analysis, optimization, and automatic vectorization with techniques based on the Chains of Recurrences (CR) algebra is proposed. The root theoretical foundations of the CR...
The OpenSPARC T1 is a multithreading processor developed and open sourced by Sun Microsystems (now Oracle). This paper presents an implementation of the low-power Tagless-Hit Instruction Cache (TH-IC) for the T1, after adapting it to the...
In all areas of research, finding the correct limiting factor able to provide the largest gains can often be the critical path of the research itself. In our work, focusing on branch prediction, we attempt to discover in what ways did...
This thesis describes the implementation of a fast, dynamic, approximate, nearest-neighbor search algorithm that works well in fixed dimensions (d The implementation is competitive with the best approximate nearest neighbor searching...
Graph drawing is widely used in many fields. Good visualization in graph drawing makes it easier for humans to understand the concepts being represented. This thesis deals with what is known as a hierarchical graph and concerns one of...
This work's focus is on the behavior analysis of data in the caching hierarchy. Especially as it pertains to the L1 data cache. Modern caching research often neglects detailed analysis of the current behavior found within the data cache...
Due to the wide use of collective operations in Message Passing Interface (MPI) applications, developing efficient collective communication routines is essential. Despite numerous research efforts for optimizing MPI collective operations...
This thesis describes two algorithms for face detection that rely on a generic feature representation called spectral histogram representation. The sufficiency and generalization of this representation is demonstrated through a...
Monte Carlo applications are widely perceived as computationally intensive but naturally parallel. Therefore, they can be effectively executed on the grid using the dynamic bag-of-work model. We improve the efficiency of the subtask...
