Solving Multiple Classes of Problems in Parallel with MATLAB*P

Choy, Ron, Edelman, Alan 01 1900 (has links)
MATLAB [7] is one of the most widely used mathematical computing environments in technical computing. It is an interactive environment that provides high performance computational routines and an easy-to-use, C-like scripting language. Mathworks, the company that develops MATLAB, currently does not provide a version of MATLAB that can utilize parallel computing [9]. This has led to academic and commercial efforts outside Mathworks to build a parallel MATLAB, using a variety of approaches. MATLAB*P is a parallel MATLAB that focus on enhancing productivity by providing an easy to use parallel computing tool. Using syntaxes identical to regular MATLAB, it can be used to solve large scale algebraic problems as well as multiple small problems in parallel. This paper describes how the innovative combination of ’*p mode’ and ’MultiMATLAB/MultiOctave mode’ in MATLAB*P can be used to solve a large range of real world problems. / Singapore-MIT Alliance (SMA)

Rendering Animations with Distributed Applets over the Internet

McMahon, Adam 01 January 2009 (has links)
High quality 3D rendering requires massive computing resources. In order to render animations within a reasonable amount of time, the rendering process is often distributed among a cluster of computers, typically called a rendering farm. However, most individuals and small studios do not have the resources to purchase or lease a rendering farm. In the late 1990?s, Java technology brought a hope that distributed applets could be utilized as an alternative to traditional network rendering models. Yet, this hope was never realized, nor was it fully implemented. Taking into account new developments in web application technology and the Sunflow renderer, this thesis will reexamine the possibility of distributed rendering applets. This thesis will suggest that distributed Java applets can effectively render projects across a collection of heterogeneous and geographically dispersed computers over the Internet. Moreover, this paper will present a prototype web application, called RenderWeb, that uses distributed applets to quickly render projects created in popular animation programs, such as Blender, 3D Studio MAX, and Softimage.

Towards a framework for intuitive programming of cellular automata

Torbey, Sami 05 December 2007 (has links)
The ability to obtain complex global behaviour from simple local rules makes cellular automata an interesting platform for massively parallel computation. However, manually designing a cellular automaton to perform a given computation can be extremely tedious, and automated design techniques such as genetic programming have their limitations because of the absence of human intuition. In this thesis, we propose elements of a framework whose goal is to make the manual synthesis of cellular automata rules exhibiting desired global characteristics more programmer-friendly, while maintaining the simplicity of local processing elements. We also demonstrate the power of that framework by using it to provide intuitive yet effective solutions to the two-dimensional majority classification problem, the convex hull of disconnected points problem, and various problems pertaining to node placement in wireless sensor networks. / Thesis (Master, Computing) -- Queen's University, 2007-12-05 10:26:09.591

Efficient Parallel Text Compression on GPUs

Zhang, Xiaoxi 2011 December 1900 (has links)
This paper demonstrates an efficient text compressor with parallel Lempel-Ziv-Markov chain algorithm (LZMA) on graphics processing units (GPUs). We divide LZMA into two parts, match finder and range encoder. We parallel both parts and achieve competitive performance with freeArc on AMD 6-core 2.81 GHz CPU. We measure match finder time, range encoder compression time and demonstrate realtime performance on a large dataset: 10 GB web pages crawled by IRLbot. Our parallel range encoder is 15 times faster than sequential algorithm (FastAC) with static model.

Automatic parallelisation for a class of URE problems

Chen, Xian January 1995 (has links)
This thesis deals with the methodology and software of automatic parallelisation for numerical supercomputing and supercomputers. Basically, we focus on the problem of Uniform Recurrence Equations (URE) which exists widely in numerical computations. vVepropose a complete methodology of automatic generation of parallel programs for regular array designs. The methodology starts with an introduction of a set of canonical dependencies which generates a general modelling of the various URE problems. Based on these canonical dependencies, partitioning and mapping methods are developed which gives the foundation of the universal design process. Using the theoretical results we propose the structures of parallel programs and eventually generate automatically parallel codes which run correctly and efficiently on transputer array. The achievements presented in this thesis can be regarded as a significant progress in the area of automatic generation of parallel codes and regular (systolic) array design. This methodology is integrated and self-contained, and may be the only practical working package in this area.

Parallel Windowed Method for Scalar Multiplication in Elliptic Curve Cryptography

Bouman, Tanya January 2021 (has links)
Commercial applications, including Blockchain, require large numbers of cryptographic signing and verification operations, increasingly using Elliptic Curve Cryptography. This uses a group operation (called point addition) in the set of points on an elliptic curve over a prime field. Scalar multiplication of the repeated addition of a fixed point, P , in the curve. Along with the infinity point, which serves as the identity of addition and the zero of scalar multiplication, this forms a vector space over the prime field. The scalar multiplication can be accelerated by decomposing the number of additions into nibbles or other digits, and using a pre-computed table of values P , 2P , 3P, . . . This is called a windowed method. To avoid side-channel attacks, implementations must ensure that the time and power used do not depend on the scalar. Avoiding conditional execution ensures constant-time and constant-power execution. This thesis presents a theoretical reduction in latency for the windowed method by introducing parallelism. Using three cores can achieve an improvement of 42% in the latency versus a single-threaded computation. / Thesis / Master of Science (MSc)
