Master Thesis
Faculty of Computer Science and Management Field of study: COMPUTER SCIENCE Specialty: Information Systems Design Master Thesis Multithreaded game engine architecture Adrian Szczerbiński keywords: game engine multithreading DirectX 12 short summary: Project, implementation and research of a multithreaded 3D game engine architecture using DirectX 12. The goal is to create a layered architecture, parallelize it and compare the results in order to state the usefulness of multithreading in game engines.

Wielowątkowość jest postrzegana jako trudne zadanie do wdrożenia i nie jest w pełni rozwinięta. Programiści często unikają jej, ponieważ do prawidłowego wdrożenia wymaga wiele pracy. Według mnie wynikający z tego wzrost wydajności jest warty tych kosztów. Ponieważ nie ma wielu silników gier, które w pełni wykorzystują wielowątkowość, celem tej pracy jest zaprojektowanie i zaproponowanie wielowątkowej architektury silnika gry 3D, a także przedstawienie głównych systemów używanych do stworzenia takiego silnika gry 3D. Praca skupia się na technologii i architekturze silnika gry i jego podsystemach wraz ze strukturami danych i algorytmami wykorzystywanymi do ich stworzenia. -

An Examination 1 Running head: AN EXAMINATION OF THE BENEFITS OF USING OPEN SOURCE An Examination of the Benefits of Using Open Source Software in Schools Charles E. Craig, Jr. Tennessee Tech University July 21, 2011 An Examination 2 Abstract This research is an examination of ways that open source software can bring educational value and significant cost savings to K-12 schools. Existing case studies and other research are examined. Particular attention is given to K-12 schools which have implemented the free and open source Linux operating system to replace Microsoft Windows on older computers, as well as schools which have replaced Microsoft Office with OpenOffice.

Annex I Definitions
Annex I Definitions Free and Open Source Software (FOSS): Software whose source code is published and made available to the public, enabling anyone to copy, modify and redistribute the source code without paying royalties or fees. Open source code evolves through community cooperation. These communities are composed of individual programmers and users as well as very large companies. Some examples of open source initiatives are GNU/Linux, Eclipse, Apache, Mozilla, and various projects hosted on SourceForge1 and Savannah2 Web sites. Proprietary software -- Software that is distributed under commercial licence agreements, usually for a fee. The main difference between the proprietary software licence and the open source licence is that the recipient does not normally receive the right to copy, modify, redistribute the software without fees or royalty obligations. Something proprietary is something exclusively owned by someone, often with connotations that it is exclusive and cannot be used by other parties without negotiations. It may specifically mean that the item is covered by one or more patents, as in proprietary technology. Proprietary software means that some individual or company holds the exclusive copyrights on a piece of software, at the same time denying others access to the software’s source code and the right to copy, modify and study the software. Open standards -- Software interfaces, protocols, or electronic formats that are openly documented and have been accepted in the industry through either formal or de facto processes, which are freely available for adoption by the industry. The open source community has been a leader in promoting and adopting open standards. Some of the success of open source software is due to the availability of worldwide standards for exchanging information, standards that have been implemented in browsers, email systems, file sharing applications and many other tools. -
