Software Design of A Sequential Loop Optimization Method on Data Locality

Luo, Yong-En 11 September 2008 (has links)
The gap between processor speed and memory access performance increases continuingly. In order to improve performance degradation due to memory accesses, we can reduce memory block accesses by improving data locality. In this research, we focus on optimizing data locality in loops. We adopt an iterative greedy algorithm. It iteratively perform loop fission and loop fusion by moving strongly-connected components among loops subject to data dependence constraints. It evaluates data locality change of each move and decide if accept such move. Subsequently loops can be improved gradually forward optimal result.

Representations and problematics of hybridity in Amitav Ghosh

趙穎璿, Chiu, Wing-suen January 2013 (has links)
Hybridity has been a privileged theory in post-colonial writings. It is considered as a source of empowerment that resists oppositional binarism and monolithic discourses that characterize dominant Western historical representations. Amitav Ghosh’s In An Antique Land and his ongoing Ibis Trilogy are historiographic projects that instantiate, both textually and formally, the employment of hybridity in resistance of cultural and political suppression. However, Ghosh at the same time interrogates the discourse of hybridity by highlighting its problematics. Such ambivalent stance creates a paradox that the author leaves open as a site for critical debates. Employing the strength of hybridity, Ghosh rewrites history and challenges the critiques that disapprove the theory for its lack of ethics and suggests that the theory of hybridity can fulfill our ethical imperatives by excavating forgotten voices of the past. / published_or_final_version / English Studies / Master / Master of Arts

Hybridity as a new genre of literature : the works of Kazuo Ishiguro

土橋今日子, Dobashi, Kyoko January 2013 (has links)
Homi K. Bhabha suggests that hybridity bridges more than just cultural, genetic, linguistic and national differences. His theory explores a hybridity that reconciles such ubiquitous peripheral differences as generational, gender, class, societal and even individual differences. Even before the era of imperialism and globalization, such hybridization was present within national and cultural frameworks. The differences were acknowledged, confronted, wrestled with and incorporated into a new entity or phenomenon – whether coherent or incoherent – and made part of a culture, society, morality, etc. This dissertation applies the workings of the hybridization logic to literature, and particularly the in-between spaces in narratology. It explores multiple aspects of the narrative’s liminalities, in character, style and structure, to pinpoint any moments that may engender hybridization in fictional discourse. Kazuo Ishiguro’s novels are replete with fused contradictions and negotiated differences on many levels, extending far beyond any genre differences. This paper seeks to define the concept and workings of ‘hybridity’ in literature through the analysis of Ishiguro’s six novels: Pale View of Hills, An Artist of the Floating World, The Remains of the Day, The Unconsoled, When We Were Orphans and Never Let Me Go. The tenets of Mikhail M. Bakhtin’s dialogism are also employed to unveil multiple connotations or different voices in a discourse, ultimately facilitating the unearthing of hybridity. This dissertation, thus, hones in in particular on the author-narrator dialogic interactions. / published_or_final_version / English Studies / Master / Master of Arts

Experimental measurement of energy transport in tokamak plasmas

Meyerson, Dmitry 17 February 2011 (has links)
A tokamak plasma near equilibrium can be perturbed with modulated power sources, such as modulated electron cyclotron heating, or repeated cold pulse application. Temperature response to cyclical changes in profiles parameters that are induced by modulated power deposition can be used to test theoretical transport models as well as improve experimental phenomenology used to optimize tokamak performance. The goal of this document to discuss some methods of analyzing electron temperature data in the context of energy transport. Specific experiments are considered in order to demonstrate the methods discussed, as well as to examine the electron energy transport properties of these shots. Electron cyclotron emission provides a convenient way to probe electron temperature for plasmas in thermal equilibrium. We can show that in tokamak devices,barring harmonic overlap, we can associate a particular frequency with a particular location in a tokamak, by carefully selecting the detection frequency and line of sight of the responsible antenna. ECE radiometers typically measure temperature at tens of locations at a time with a spatial resolution on the order of a few centimeters. Tracking the evolution of electron energy flux depends on careful analysis of the resulting data. The most straightforward way to analyze temperature perturbations is to simply consider various harmonics of the driving source and consider the corresponding harmonics in the temperature. We can analyze the phase and amplitude of the response to find the effective phase velocity of the perturbation which can in turn be related to parameters in the selected heat flux model. The most common example is to determine , the diffusion coefficient that appears in the linearized energy transport equation. The advantages and limitation of this method will be discussed in detail in Section 3. A more involved approach involves using the perturbed temperature data to compute modulated heat flux at any given point in the perturbation cycle, rather than using the temperature data directly. As before the heat flux can then be related to measured profile parameters and theoretical predictions. The advantages and limitations of this approach will be discussed in more detail. Both of the mentioned analysis methods are used to probe electron energy transport in a quiescent H mode (QH mode) shot conducted at DIIID. The nature of the internal transport barrier that is present in the shot is considered in light of the results. / text
