IDE for SCADA Development at CERN
Mareček, Matěj ; Holík, Lukáš (referee) ; Křivka, Zbyněk (advisor)
Cílem této magisterské práce je navrhnout a implementovat IDE (integrované vývojové prostředí), které zvýší efektivitu a bezpečnost vývoje pro SIMATIC WinCC Open Architecture. Tato práce je založena na výzkumu provedeném týmem z Technické univerzity v Eindhovenu a splňuje požadavky pocházející ze SCD sekce v CERN (Evropské organizace pro jaderný výzkum). Vyvinuté IDE je postaveno na platformě Eclipse, přičemž pro syntaktickou analýzu, linkování a sémantickou analýzu kódu používá Xtext framework. IDE nabízí také podporu pro nově vytvořený programovací jazyk, který umožňuje programátorům jednoduše nadefinovat šablonu pro konfigurační soubory používané WinCC OA. Interpret tohoto nového jazyka je schopen provést syntaktickou analýzu šablony a konfiguračního souboru a rozhodnout, zdali konfigurační soubor odpovídá šabloně. Praktickým výstupem této práce je integrované vývojové prostředí, které podporuje vývoj WinCC OA aplikací v CERN a periodicky provádí analýzu kódu těchto aplikací napsaného v jazyce Control script.

Automatic Comparison of Static Analysis Outputs on Different Versions of Programs
Kompová, Radmila ; Müller, Petr (referee) ; Vojnar, Tomáš (advisor)
This thesis aims at development of a tool support for comparing the output of static analysis applied to different versions of program source codes. The thesis also comprises a discussion of three opensource static analyzers of the C source code. Based on this discussion, one of these analyzers, Cppcheck, was chosen for the implementation of the designed tool. The static analyzer's outputs, obtained for various versions of a specific program, are compared on the basis of the context of the line at which an error was found. The patch utility is used for comparing the appropriate contexts. Detected errors are classified into three groups: new, old, and fixed errors. A web interface allowing an easier-to-follow presentation of the results is also provided. The designed tool set has been successfully tested on three opensource projects, including the Linux kernel, Coreutils and CPython.

Static Analysis of C Programs in Sparse and Similar Tools
Nagy, Martin ; Peringer, Petr (referee) ; Vojnar, Tomáš (advisor)
Software verification is steadily becoming important for software developers and companies to ensure software quality. However, the problem of writing a good static code analysis tool often stems from the lack of a good compiler front-end. To solve this problem, we try to analyse and document an existing tool called Sparse to empower software verification researchers with a ready, stable solution for their projects. Additionally, we also talk about Mygcc and it's new approach to integrate with existing compilers.

Bobox Runtime Optimization
Krížik, Lukáš ; Zavoral, Filip (advisor) ; Parízek, Pavel (referee)
The goal of this thesis is to create a tool for an optimization of code for the task-based parallel framework called Bobox. The optimizer tool reduces a number of short and long running tasks based on a static code analysis. Some cases of short-running tasks cause an unnecessary scheduling overhead. The Bobox scheduler can schedule a task even though the task does not have all input data. Unless, the scheduler has enough information not to schedule such task. In order to remove such short-running task, the tool analyses its input usage and informs the scheduler. Long-running tasks inhibit a parallel execution in some cases. A bigger task granularity can significantly improve execution times in a parallel environment. In order to remove a long-running task, the tool has to be able to evaluate a runtime code complexity and yield a task execution in the appropriate place. Powered by TCPDF (www.tcpdf.org)
