The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Booting Linux Really FastParthey, Daniel 11 April 2006 (has links) (PDF)
Diese Arbeit untersucht die Dauer von Bootvorgängen auf Linux-Systemen vom Einschalten des Rechners bis zur Benutzeranmeldung. Zeitintensive Abschnitte des Bootvorganges werden untersucht und Methoden zur Beschleunigung diskutiert. Dies beinhaltet eine Analyse verschiedener BIOS Versionen, der Kernel-Initialisierung und unterschiedliche Ansätze, Dienste zu starten. Es werden Startvorgänge eines gewöhnlichen Desktop-Systems mit einem eingebetteten VIA EPIA-ML-6000EA Mini-ITX System verglichen. / This research project evaluates startup times of the linux boot process from power-on until user login. Time consuming parts of the boot process are investigated and methods how to speed up the whole process are discussed. It includes an analysis and comparison of different BIOSes, the kernel startup sequence and different approaches to start user space services. This project also compares the startup times of everyday desktop systems with the EPIA-ML6000EA Mini-ITX board, an embedded x86-compatible system.

ESPGOALSchneider, Timo, Eckelmann, Sven 18 May 2011 (has links) (PDF)
Optimized implementations of blocking and nonblocking collective operations are most important for scalable high-performance applications. Offloading such collective operations into the communication layer can improve performance and asynchronous progression of the operations. However, it is most important that such offloading schemes remain flexible in order to support user-defined (sparse neighbor) collective communications. In this work, we describe an operating system kernel-based architecture for implementing an interpreter for the flexible Group Operation Assembly Language (GOAL) framework to offload collective communications. We describe an optimized scheme to store the schedules that define the collective operations and show an extension to profile the performance of the kernel layer. Our microbenchmarks demonstrate the effectiveness of the approach and we show performance improvements over traditional progression in user-space. We also discuss complications with the design and offloading strategies in general.

Chemnitzer Linux-Tage 2010Demierre, Andéol, Eggers, Monika, Garbe, Anselm R., Groß, Thomas, Jaenisch, Volker, Jung, Marco, Knopper, Klaus, Lang, Jens, Luithardt, Wolfram, Noble, Howard, Obst, Marcus, Pucklitzsch, Thomas, Schlittermann, Heiko, Schumacher, Stefan, Seidel, Philipp, Spillner, Josef, Tang, Kang, Walle, Bernhard, Wetzel, Ulrich 16 April 2010 (has links) (PDF)
Die Chemnitzer Linux-Tage fanden am 13. und 14. März 2010 auf dem
Campus der Technischen Universität Chemnitz statt. Neben den Präsentationen
im Foyer zogen vor allem die Vorträge über 2500 Besucher zur 12. Auflage
der Veranstaltung.
Der Band vereint den Inhalt von 15 Hauptvorträgen und die Abstrakts von
76 weiteren Beiträgen und stellt damit einen Überblick über das weit
gefächerte Programm der Veranstaltung dar. / The Chemnitz Linux Days took place at the campus of the Chemnitz University
of Technology. Besides the presentations at the foyer the lectures were
first of all attractive for more than 2.500 visitors.
This volume contains the content of 15 main lectures and abstracts of 76
further talks and hence gives a survey of the broadly based program
of this event.
