High Performance Applications on Intel Xeon Phi Cluster
Kačurik, Tomáš ; Hrbáček, Radek (referee) ; Jaroš, Jiří (advisor)
The main topic of this thesis is the implementation and subsequent optimization of high performance applications on a cluster of Intel Xeon Phi coprocessors. Using two approaches to solve the N-Body problem, the possibilities of the program execution on a cluster of processors, coprocessors or both device types have been demonstrated. Two particular versions of the N-Body problem have been chosen - the naive and Barnes-hut. Both problems have been implemented and optimized. For better comparison of the achieved results, we only considered achieved acceleration against single node runs using processors only. In the case of the naive version a 15-fold increase has been achieved when using combination of processors and coprocessors on 8 computational nodes. The performance in this case was 9 TFLOP/s. Based on the obtained results we concluded the advantages and disadvantages of the program execution in the distributed environments using processors, coprocessors or both.

Efficient Transport of Electronic Mail with Microsoft Exchange Plugin
Jakubis, Tomáš ; Homoliak, Ivan (referee) ; Kováčik, Michal (advisor)
This project discusses optimization of e-mail and SMTP traffic in proprietary product of Microsoft Exchange 2013 in regard of marine industry. The goal is at first to analyze the requirements of this service on slow and unreliable network connections, SMTP traffic and then the product itself. Afterwards it defines specification for the final product and prepares the test environment. Design and implementation of transport agent using Exchange Management Shell is described for synchronization of two installations of Microsoft Exchange 2013; and focuses on emerged problems during the development, discusses different approaches and possible solutions. Testing shows various shortcomings of found solution. Finally, analysis of final solution shows possible future improvements and a need of security upgrade before applying to production environment.

Algorithms for advance production planning and scheduling
Kršák, Pavol ; Kaczmarczyk, Václav (referee) ; Pásek, Jan (advisor)
Bachelor‘s thesis analyzes solution of operational problems of production planning. Pur- pose of the thesis is presentation of operational problems of production planning and following proposal and implementation of planning algorithms in language C# on specific planning problem. By the presentation of the problematic is listed company „COMPAS automatizace s.r.o.”, which enabled implementation of the project. The thesis analyzes planning methods and process of their implementation. More specifically the thesis ana- lyzes evolutionary algorithms, expert systems in planning and deterministic planning via linear programming. In third chapter is described in more details planning program of production of coffee blends, which was provided by COMPAS company. Like a next, the thesis describes specifically proposal of solving based on evolutionary principle. The solving consists of the model of technology designed to production of coffee blends and ActionList. ActionList represents a set of rules that are governed by model. Then ru- les are defined undergone an evolutionary process in an effort to find better solution the existing. Applied features implemented in the system COMES to repurpose by the imple- mentation of module COMES Modeller are developed together with detailed description in the fourth chapter.

Model of MOSFET transistor in program SystemVision
Michálek, Branislav ; Brančík, Lubomír (referee) ; Kolka, Zdeněk (advisor)
This bachelor thesis deals with modeling of MOS transistor. The theoretical part of the thesis is dedicated to analysis of basic MOSFET structure and operation, basics of modeling in general, descriptions of SPICE models LEVEL1 and LEVEL3 and model parameters extraction by using the optimization technique. The realization part is dedicated to creation of static models for DC analysis for three specific MOS transistors in the form of netlist used in SPICE circuit simulators, using the model parameters, which have been obtained by using the optimization technique in Matlab. Validity of realized models is then verified by comparing of its characteristics, obtained from simulation in SystemVision program, with characteristics from transistor’s datasheets.

Hardware Acceleration of Cipher Attack
Okuliar, Adam ; Slaný, Karel (referee) ; Vašíček, Zdeněk (advisor)
Hardware acceleration is often good tool to achieve significantly better performance of processing great ammount of data or of realization of parallel algoritms. Aim of this work is to demonstrate resoluts of using FPGA circuits for implementation exponentially complex algorithm. As example haschosen brute-force attack on WEP cryptographic algorithm with 40-bit long key. Goal of this work is to compare properties and performance of software and hardware implementation of choosen algorithm.
