Acceleration of Applications with FPGA-Based Computing Machines: Code Restructuring
FACULDADE DE ENGENHARIA DA UNIVERSIDADE DO PORTO Acceleration of Applications with FPGA-Based Computing Machines: Code Restructuring Tiago Lascasas dos Santos Mestrado Integrado em Engenharia Informática e Computação Supervisor: João M. P. Cardoso, PhD Co-supervisor: João Bispo, PhD July 31, 2020 c Tiago Santos, 2020 Acceleration of Applications with FPGA-Based Computing Machines: Code Restructuring Tiago Lascasas dos Santos Mestrado Integrado em Engenharia Informática e Computação Approved in oral examination by the committee: Chair: Prof. João Paulo de Castro Canas Ferreira, PhD External Examiner: Dr. José Gabriel de Figueiredo Coutinho, PhD Supervisor: Prof. João Manuel Paiva Cardoso, PhD July 31, 2020 Abstract Field-programmable gate arrays (FPGAs) can be used to accelerate performance-critical programs from a wide range of fields and still providing energy-efficient solutions. Programs written in high level languages, such as C and C++, can be compiled to FPGAs through High-level Synthesis (HLS). Although FPGAs benefit the most from parallel and data-streaming applications, efficient compilation to FPGAs is a problem for both tools and developers. Most applications do not follow these patterns, and extensive code restructuring and the use of HLS directives need to be applied to a program in order to take advantage of FPGAs. Code restructuring and the use of HLS directives often needs to be manually performed by an experienced developer, and as such there is a need to automate this process. This dissertation proposes a framework that automatically optimizes C code via directives, using a source-to-source compiler on a stage prior to HLS. This optimization is primarily applied by strategies that select, configure and insert directives on the code to be input to an HLS tool, e.g., Vivado HLS, in order to synthesize more efficient hardware accelerators. -

Locks and Raspberries: a Comparative Study of Single-Board Computers for Access Control
UPTEC F 16013 Examensarbete 30 hp April 2016 Locks and raspberries: a comparative study of single-board computers for access control Andreas Romin Abstract Locks and raspberries: a comparative study of single-board computers for access control Andreas Romin Teknisk- naturvetenskaplig fakultet UTH-enheten Over the past decade, there has been a drastic development of the single-board computer market. These computers are now in a position where they can compete Besöksadress: with classic embedded hardware. Such fast improvement has led ASSA ABLOY, a Ångströmlaboratoriet Lägerhyddsvägen 1 well-known lock and security company, to see value in replacing some of their Hus 4, Plan 0 existing access control hardware with an off-the-shelf single-board computer. Therefore, a comparative study of single-board computers was performed for this Postadress: company. Some of the compared properties were price, performance (i.e. CPU, Box 536 751 21 Uppsala memory, USB, network, operating temperature and power consumption) and other relevant information such as operating systems, open/closed source hardware and Telefon: future availability. Information and testing data from nine different computers was 018 – 471 30 03 compiled and analyzed. This data was then used to determine the best-suited Telefax: candidates that could possibly replace the current access control hardware. They 018 – 471 30 00 were chosen in accordance to three different categories: performance, power consumption and open source hardware. The ODROID C1+, the Raspberry Pi A+ Hemsida: and the A20 OLinuXino Lime2 proved to be the best candidates for these three http://www.teknat.uu.se/student categories respectively. Furthermore, it was also concluded that the company behind a computer is just as important as the computer itself, where the best company in this study was determined to be Olimex. -

Reactos Suspends Development for Source Code Review - Linux.Com Reactos Suspends Development for Source Code Review by - February 1, 2006
8/20/2020 ReactOS suspends development for source code review - Linux.com ReactOS suspends development for source code review By - February 1, 2006 Author: Stephen Feller The ReactOS team has suspended development to do a code review amid concerns that stolen code from the world’s most used OS found its way into the project. ReactOS, the 10-year-old project to create a functional, free, and open source version of Windows NT, suspended development on January 27 after a meeting to discuss whether leaked code had been added to the project’s code base. The OS also will not be available for download while developers perform a full review of the 3 million or so lines in the ReactOS code base. A letter posted to the ReactOS Web site included three specific tasks developers will take on as a result of the concerns: Clarify the ReactOS Intellectual Property Policy Statement requirements for clean room reverse engineering to conform to those required by US law; audit the ReactOS code base and rewrite any code that was not implemented along the clarified guidelines; and require developers contributing major code to the project to sign a document that says they agree to the project’s policies. According to Steven Edwards, the recently elected project coordinator for ReactOS, developers on the project have raised the possibility that a developer had reverse-engineered a part of the Windows code in violation of US copyright and trade secrecy laws and practices. Leaks of parts of the source code for Windows 2000 and NT have been circulating on the Internet for a few years, but “there is nothing in the code base that we believe is a copy and paste from a leaked bad source,” Edwards said. -
A Crack on the Glass Evaluation of Consumer Windows OS Security Architecture and Its Feasibility As a Potential Isolation Provider for "Qubes Windows Lite"
A crack on the glass Evaluation of consumer Windows OS security architecture and its feasibility as a potential isolation provider for "Qubes Windows Lite" “Well, dreams, they feel real while we're in them right? Its only when we wake up then we realize that something was actually strange.” -- Cobb, Inception Abstract In this paper we describe our attempt at creating Qubes Windows Native Isolation system, which is a collection of isolated application containers. We discuss the project requirements, what technical means are needed to implement such system and why the available Windows APIs and system architecture is not appropriate for the task. Rafał Wojdyła, Invisible Things Lab [email protected] Page 1 1. Introduction to Qubes OS Qubes OS strives to provide strong desktop security by isolation [1]. Having separate domains dedicated to different tasks helps to mitigate potential attacks – a PDF exploit coming from an untrusted site that compromises “public” domain will not affect “work” domain provided they are properly isolated. Qubes R2 is built on top of a Linux host and Xen hypervisor – domains are implemented as lightweight VMs administered from the trusted one, traditionally called dom0. This of course implies we trust that Xen-provided isolation is good, but one needs to start somewhere. The next iteration of Qubes is built on top of the Odyssey framework [2] – the goal of which is to decouple Qubes core from Xen. Qubes Odyssey uses the libvirt [3] project to implement a hypervisor abstraction layer. That means we can replace Xen with a different virtual machine manager (VMM) – Hyper-V, Virtual Box, VMWare or others. -

Partial Array Self-Refresh in Linux
Partial Array Self-refresh in Linux Henrik Kjellberg, E05 [email protected] March 7, 2010 Abstract Partial Array Self-refresh is a technique to turn o the memory self- refresh from parts of a memory if it is not used, to reduce the power consumption during idle mode. In this paper I will start with describing what Partial Array Self- refresh is. I will briey describe the memory management in Linux and how it works. I will describe some dierent approaches that can be used to accomplish Partial Array Self-refresh in a Linux environment and then implement one of the approaches. I will also describe what else has to be done to achieve good results from Partial Array Self-refresh in the form of defragmentation and anti-fragmentation. 1 2 Contents 1 Introduction 6 2 Previous work 6 3 Aim of the thesis 7 4 Memory system overview 7 4.1 Paging . 7 4.2 Non-Unied Memory Access . 8 4.3 Virtual memory . 8 4.4 Linux . 8 4.4.1 The Buddy Allocator . 9 4.4.2 The SLAB allocator . 10 5 Design analysis 11 5.1 Disabling of allocations . 12 5.1.1 Memory hotplug . 12 5.1.2 Pre-validate power down . 13 5.2 Defragmentation . 13 5.3 Anti-fragmentation . 14 6 My implementation 15 7 Evaluation 17 7.1 Partial Array Self-refresh (PASR) feasibility . 17 7.2 Overhead . 18 8 The future 19 9 Conclusions 21 10 Acknowledgements 22 Appendix A: Tools 23 A.1 Procfs . 23 A.2 Pasr-info .
