DISSERTATION Concepts for Scientific Computing
DISSERTATION Concepts for Scientific Computing ausgefuhrt¨ zum Zwecke der Erlangung des akademischen Grades eines Doktors der technischen Wissenschaften eingereicht an der Technischen Universitat¨ Wien Fakultat¨ fur¨ Elektrotechnik und Informationstechnik von RENE´ HEINZL Rosensteingasse 7-9/2 A-1160 Wien, Osterreich¨ Matr. Nr. 9826031 geboren am 6. September 1977, Wien Wien, im Juli 2007 Abstract Scientific computing has traditionally been concerned with numerical issues such as the convergence of discrete approximations to partial differential equations, the stability of integration methods for time- dependent systems, and the computational efficiency of software implementations of these numerical methods. While computer performance is steadily increasing the additional complexity of these simulation models easily outgrows this gain in computational power. It is therefore of utmost importance to employ the latest techniques of software development to obtain high performance and thereby ensure adequate simulation times even for complex problems. As a consequence the development of high performance simulation software is quite challenging. Originating in the field of technology computer aided design as an important and complex area of sci- entific computing, this work is motivated by the fact, that different concepts were developed during the last decades for the field of scientific computing. The great diversity of physical phenomena present in semiconductor devices themselves and in the processes involved in their manufacture make the field of TCAD extremely challenging. Each of the phenomena can be described by differential equations of vary- ing complexity. The development of several different discretisation schemes has been necessary in order to best model the underlying physics and to accommodate the mathematical peculiarities of each of these equations while transferring them to the discrete world of digital computing. -
HAIL: an Algorithm for the Hardware Accelerated Identification of Languages, Master's Thesis, May 2006
Washington University in St. Louis Washington University Open Scholarship All Computer Science and Engineering Research Computer Science and Engineering Report Number: WUCSE-2006-36 2006-01-01 HAIL: An Algorithm for the Hardware Accelerated Identification of Languages, Master's Thesis, May 2006 Charles M. Kastner This thesis examines in detail the Hardware-Accelerated Identification of Languages (HAIL) project. The goal of HAIL is to provide an accurate means to identify the language and encoding used in streaming content, such as documents passed over a high-speed network. HAIL has been implemented on the Field-programmable Port eXtender (FPX), an open hardware platform developed at Washington University in St. Louis. HAIL can accurately identify the primary languages and encodings used in text at rates much higher than what can be achieved by software algorithms running on microprocessors.

Hacker Culture & Politics
HACKER CULTURE & POLITICS COMS 541 (CRN 15368) 1435-1725 Department of Art History and Communication Studies McGill University Professor Gabriella Coleman Fall 2012 Arts W-220/ 14:35-17:25 Professor: Dr. Gabriella Coleman Office: Arts W-110 Office hours: Sign up sheet Tuesday 2:30-3:30 PM Phone: xxx E-mail: [email protected] OVERVIEW This course examines computer hackers to interrogate not only the ethics and technical practices of hacking, but to examine more broadly how hackers and hacking have transformed the politics of computing and the Internet more generally. We will examine how hacker values are realized and constituted by different legal, technical, and ethical activities of computer hacking—for example, free software production, cyberactivism and hactivism, cryptography, and the prankish games of hacker underground. We will pay close attention to how ethical principles are variably represented and thought of by hackers, journalists, and academics and we will use the example of hacking to address various topics on law, order, and politics on the Internet such as: free speech and censorship, privacy, security, surveillance, and intellectual property. We finish with an in-depth look at two sites of hacker and activist action: Wikileaks and Anonymous. LEARNER OBJECTIVES This will allow us to 1) demonstrate familiarity with variants of hacking 2) critically examine the multiple ways hackers draw on and reconfigure dominant ideas of property, freedom, and privacy through their diverse moral 1 codes and technical activities 3) broaden our understanding of politics of the Internet by evaluating the various political effects and ramifications of hacking. -

Thanks also to Matthew Westcott for helping me to understand TR-DOS a little better. ZXF magazine delights in reporting on the achievements of the members of the Spectrum community and is indebited to them all for their efforts. In particular, ZXF could not have achieved its current distribution without the hosting offered by Martijn van der Heide at www.worldofspectrum.org, whose own contribution to the Spectrum scene goes well beyond the easily measurable.

You think that new technology is great - of course you do - but ever since you packed away that old Spectrum in a box and taped up the lid something has most definitely been missing. At last you understand you were turning your back on more than just an obsolete computer. The good news is that you don't have to fish the box out from under the bed just yet (or lament its sale on ebay or at the local car boot): the Spectrum is one of the most emulated computers (if not the most emulated computer) on the planet and the quality of its emulation is just superb. -

Control Flow
Control Flow The control flow of a program is the way an execution moves from statement to statement. The textbook breaks it down into: Sequencing (do the next thing) Selection (pick something to do, e.g. if , switch) Iteration (repeat something, e.g. while, for) Recursion Unstructured (e.g. goto) Roche (USNA) SI413 - Class 23 Fall 2011 1 / 12 Unstructured flow: GOTO In the beginning, there was GOTO. And GOTO was good. Directly jumps from one place (the goto) to another (the label) Corresponds exactly to machine code Very efficient Can cause some problems. Roche (USNA) SI413 - Class 23 Fall 2011 2 / 12 Good Use of Goto? Say we want to print a vector, comma-separated, like “1, 2, 3”. This solution prints an extra comma! vector< i n t >v; // ... i n t i = 0; w h i l e (i<v.size()){ cout <<v[i] << ”, ”; ++i; } cout << endl; Roche (USNA) SI413 - Class 23 Fall 2011 3 / 12 Goto Problems They don’t play well with scopes. (Restricting to local gotos avoids this.) Can be used to cook up “spaghetti code” — hard to follow. Hard to know where we are in the program, i.e., hard to reason about the program’s correctness/performance.

Msc THESIS Exploiting the Reconfigurability of Ρ-VEX Processor for Real-Time Robotic Applications
Computer Engineering 2016 Mekelweg 4, 2628 CD Delft The Netherlands http://ce.et.tudelft.nl/ MSc THESIS Exploiting the Reconfigurability of ρ-VEX Processor for Real-Time Robotic Applications Muhammad Muneeb Yousaf Abstract Autonomous mobile robots generally have limited computational power on-board, and they have to perform their tasks in real-time in order to interact with their surroundings effectively. Therefore, there is a need to utilize the available computational capabilities ef- ficiently. The ρ-VEX is a run-time reconfigurable VLIW processor. CE-MS-2016-10 This unique processor allows separation of its issue lanes to form independently operating processing cores. Switching between these configurations during run-time allows optimizing the computing re- sources for the task(s) it is performing. In this project FreeRTOS is ported to the ρ-VEX processor and a control layer is developed. FreeRTOS manages the applications based on given real time parameters. The control layer decides the number of active cores (hardware contexts) and issue width of each core to best match the processing requirements of the applications. In this way, FreeRTOS and the control layer together can reconfigure the number of active cores at run-time. This is a very unique feature of this thesis project and can not be found in any other multicore implementation of FreeRTOS. The control layer along with FreeR- TOS provides the user a facility to run applications under real-time constraints and with the best possible efficiency. In order to evaluate the performance, the overhead of the FreeRTOS is quantified and a performance comparison is made between several configurations of this system. -
Introduction Making and Hacking
Introduction Making and Hacking Annika Richterich and Karin Wenz “While hacking is a wonderful way of viewing the world, ‘making’ was a more positive framing for customizing and changing the world.” (DOUGHERTY 2014) In August 2014, hackerspaces in the Netherlands issued an open letter to the Dutch Public Prosecution Service (PPS): in this document, members of hacker communi- ties from Amsterdam, Heerlen, Utrecht and other cities called upon the govern- mental institution to revise the definition of ‘hacking’ as presented on its website (Walboer et al. 2014). While the PPS described it as “breaking into computers without permission”, the hackerspace members highlighted that hacking refers to citizens’ creative engagement with technologies. Opposing the reduction of hacking to illegal activities, they described hacking as exploration of technological possibilities and boundaries in unforeseen, innovative ways. Even though this particular initiative was started in the Netherlands, the letter echoes wider, historical as well as ongoing negotiations regarding the meanings and origins of hacking. It seems closely related to earlier requests such as an open letter to the Wall Street Journal which was written more than 20 years ago by Richard Stallman (presumably). In this letter, the founder of the Free Software Foundation states: There’s nothing shameful about the hacking I do. But when I tell people I am a hacker, people think I’m admitting something naughty – because newspapers such as yours misuse the word ‘hacker’, giving the impression that it means ‘security breaker’ and nothing else. You are giving hackers a bad name. (Raymond 1996: 532) While one cannot find any explicit reference to this letter on Stallman’s own website, similar statements were made in his article ‘On Hacking’ (n.
