Comparison of Distribtued File System Features
Tomec, Martin ; Kašpárek, Tomáš (referee) ; Szőke, Igor (advisor)
This work deals with comparsion of distributed filesystems Ceph, Lustre and Kosmos FS. General properties of these systems are summarized here, including method of their installing, configuring and launching. Testing tools and test sets are described in the next part. Performance and abilities of these systems were tested on a network of nine computers. Last part contains analyses and evaluation of results, figuring out bottleneck of these systems. Lustre seems to be the best of these systems.

Porting of RedirFS on Other OS
Czerner, Lukáš ; Čejka, Rudolf (referee) ; Kašpárek, Tomáš (advisor)
This thesis describes preparation for porting as well aw porting itself of RedirFS Linux kernel module to FreeBSD. Basic differences between Linux and FreeBSD kernels are described as well as differences in implementation of the Virtual Filesystem, crucial part for RedirFS. Further there are described possibilities and different approaches to implementation RedirFS functionality to FreeBSD. Then, the possibilities are evaluated and ideal approach is proposed. Next chapters introduces required functionality of the new module as well as its solutions. Then the implementation details are described so the reader can very well understand how the new module works and how the required functionality is implemented into the module.

Using GPU for HPC
Máček, Branislav ; Szőke, Igor (referee) ; Kašpárek, Tomáš (advisor)
Recently there was a significant grow in building HPC systems. Nowadays they are building from mainstream computer components. One of them is graphics accelerators with GPU. This thesis deals with description of graphics accelerators. It examines possibilities usage. GPU chip has hundreds simple processors. This thesis examine possibilities how to benefit from these parallel processors. It contains description of several testing applications, discuss results from experiments and compares them with another components used for HPC.

Management Application for Touristic Routes in OSM
Švaňa, Petr ; Michal, Bohumil (referee) ; Kašpárek, Tomáš (advisor)
Bachelor thesis deals with alalysis of Czech Tourist Club hiking routes and checking their data validity in OpenStreetMap internet map source. In the resulting application has user at his disposal visialized OpenStreetMap data and implemented gadgets to simplify the control of these data. First, introduction to this topic is discussed including information about both data model, that OpenStreetMaps uses, and mapping of the tourist trails. Second, analysis of current ways for map data checking along with development of the application, that can bring these controls into practice are concerned. In following chapters, created implementation of the application with detailed manual can be found.

Own OSM Map Generator Appliance - Online
Fabčinová, Dominika ; Novotný, Tomáš (referee) ; Kašpárek, Tomáš (advisor)
Thesis analyzes steps of creating maps from OpenStreetMap data. It examines tools, that can be used to perform those steps, evaluates them and their variations with the goal of choosing one suitable to be used in implementation. Then it implements the entire proposed solution using the selected tools from obtaining the data, through rendering map images, to serving them to end users. The procedure is documented thoroughly. It shows how to insert your own layers to the map, in this case counour lines and walking trails and how to search for routes.

Coordinate System Conversion Options for Web Application
Fiala, Marek ; Michal, Bohumil (referee) ; Kašpárek, Tomáš (advisor)
The aim of this work is to find and compare tools and libraries for conversion of coordinates between Coordinate System WGS84, S-JTSK, UTM zone 33N and Pseudo-Mercator, which could be used in Web Application. Found options are then tested with focus on speed and accuracy of conversion. The main result of this work is list of usable possibilities for coordinate system conversion including comparison of performance and accuracy and its advantages and disadvantages.

Own OSM Map Generator Appliance - Offline
Hnilica, Přemek ; Novotný, Tomáš (referee) ; Kašpárek, Tomáš (advisor)
Goal of this thesis is to show reader a complete overview about possibilities of processing map data from project OpenStreetMap, to show each step of generating off-line map and describe its advantages and disadvantages. Next goal of this thesis is to implement one processing pipeline for generating offline map including contour lines and hiking trails.
