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. -

High Performance Web Servers: a Study in Concurrent Programming Models
High Performance Web Servers: A Study In Concurrent Programming Models by Srihari Radhakrishnan A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Master of Mathematics in Computer Science Waterloo, Ontario, Canada, 2019 c Srihari Radhakrishnan 2019 Author’s Declaration I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract With the advent of commodity large-scale multi-core computers, the performance of software running on these computers has become a challenge to researchers and enterprise developers. While academic research and industrial products have moved in the direction of writing scalable and highly available services using distributed computing, single machine performance remains an active domain, one which is far from saturated. This thesis selects an archetypal software example and workload in this domain, and de- scribes software characteristics affecting performance. The example is highly-parallel web- servers processing a static workload. Particularly, this work examines concurrent programming models in the context of high-performance web-servers across different architectures — threaded (Apache, Go and µKnot), event-driven (Nginx, µServer) and staged (WatPipe) — compared with two static workloads in two different domains. The two workloads are a Zipf distribution of file sizes representing a user session pulling an assortment of many small and a few large files, and a 50KB file representing chunked streaming of a large audio or video file. -

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. -

Introduction to 64 Bit Intel Assembly Language Programming for Linux
Introduction to 64 Bit Intel Assembly Language Programming for Linux Introduction to 64 Bit Intel Assembly Language Programming for Linux Ray Seyfarth October 27, 2011 Ray Seyfarth School of Computing University of Southern Mississippi Hattiesburg, MS 39406 USA Seyfarth, Ray Introduction to 64 Bit Intel Assembly Language Programming Includes index.

This work may not be translated or copied in whole or in part without the written permission of the copyright holder, except for brief excerpts in connection with reviews or scholarly analyses. Preface The Intel CPU architecture has evolved over 3 decades fr om a 16 bit CPU with no memory protection, through a period with 32 bit processors with sophisticated architectures into the current series of processors which support all the old modes of operation in addition to a greatly expanded 64 bit mode of operation. Assembly textbooks tend to focus on the history and generally conclude with a discussion on the 32 bit mode. Students are introduced to the concepts of 16 bit CPUs with segment registers allowing access to 1 megabyte of internal memory. This is an unnecessary fo cus on the past. With the x86-64 architecture there is almost a complete departure from the past. Segment registers are essentially obsolete and more reg ister usage is completely general purpose, with the glaring exception of the repeat-string loops which use specific registers and have no operands. Both these changes contribute to simpler assembly language program mmg. There are now 16 general purpose integer registers with a few spe cialized instructions. -
