Design and Implementation of the Spad Filesystem
Patočka, Mikuláš ; Zavoral, Filip (advisor) ; Matyska, Luděk (referee) ; Badica, Costin (referee) ; Višňovský, Stanislav (referee)
This thesis describes design and implementation of the Spad filesystem. I present my novel method for maintaining filesystem consistency - crash counts. I describe architecture of other filesystems and present my own design decisions in directory management, file allocation information, free space management, block allocation strategy and filesystem checking algorithm. I experimentally evaluate performance of the filesystem. I evaluate performance of the same filesystem on two different operating systems, enabling the reader to make a conclusion on how much the performance of various tasks is affected by operating system and how much by physical layout of data on disk.

Scripting of Common Information Model
Mrázik, Martin ; Višňovský, Stanislav (advisor) ; Adámek, Jiří (referee)
This work investigates how system management applications could be rapidly developed with management protocols defined by Distributed Management Task Force (DMTF) and open-source programming languages. The focus is on Common Information Model (CIM), Web Based Enterprise Management (WBEM) and scripting languages. CIM and WBEM are briefly described and the basic terminology of these standards and their infrastructure is introduced. Goals such as object-oriented mapping, shell enablement or generating documentation for CIM classes are discussed. Similar work in this area with their strengths and weaknesses are covered. Requirements for a scripting language are stated and Python is selected for this work with a discussion of some of its more interesting features. Later, Python mapping of Common Information Model is defined with the focus on Python features and conventions. As a proof of concept a prototype mapping (called powerCIM) is implemented and a few examples of management scripts are provided demonstrating the synergy with other open-source projects and libraries such as IPython or PyQt.
