Letko, Zdeněk. "Analýza a testování vícevláknových programů." Doctoral thesis, Vysoké učení technické v Brně. Fakulta informačních technologií, 2012. http://www.nusl.cz/ntk/nusl-261265.
Full textAbstract:
V disertační práci je nejprve uvedena taxonomie chyb v souběžném zpracování dat a přehled technik pro jejich dynamickou detekci. Následně jsou navrženy nové metriky pro měření synchronizace a souběžného chování programů společně s metodologií jejich odvozování. Tyto techniky se zejména uplatní v testování využívajícím techniky prohledávání prostoru a v saturačním testování. Práce dále představuje novou heuristiku vkládání šumu, jejímž cílem je maximalizace proložení instrukcí pozorovaných během testování. Tato heuristika je porovnána s již existujícími heuristikami na několika testech. Výsledky ukazují, že nová heuristika překonává ty existující v určitých případech. Nakonec práce představuje inovativní aplikaci stochastických optimalizačních algoritmů v procesu testování vícevláknových aplikací. Principem metody je hledání vhodných kombinací parametrů testů a metod vkládání šumu. Tato metoda byla prototypově implementována a otestována na množině testovacích příkladů. Výsledky ukazují, že metoda má potenciál vyznamně vylepšit testování vícevláknových programů.

Vašíček, Ondřej. "Adaptér OSLC pro analýzu softwaru." Master's thesis, Vysoké učení technické v Brně. Fakulta informačních technologií, 2021. http://www.nusl.cz/ntk/nusl-445498.
Full textAbstract:
Cílem této práce je poskytnout snadný způsob, jak rozšířit analyzační nástroj o rozhraní splňující standard OSLC. Takové rozhraní umožňuje jednoduchou integraci nástrojů s jinými nástroji nebo systémy, umožňuje jejich vzdálené použití skrze webové služby a umožňuje je jednoduše propojit s databází pro databázové dotazy a pro perzistentní uložení dat. Toto je dosaženo návrhem a implementací OSLC adaptéru pomocí sady nástrojů Eclipse Lyo. Adaptér používá jako rozhraní doménu OSLC Automation a je dostatečně univerzální na to, aby skrze toto rozhraní pokryl funkcionalitu většiny analyzačních nástrojů za pomocí jejich stávajících rozhraní na příkazové řádce. Tato práce poskytuje úvod k OSLC, Eclipse Lyo a souvisejícím konceptům. Dále tato práce definuje požadavky a odlišnosti různých analyzačních nástrojů a diskutuje návrh adaptéru a faktory, které ovlivnily návrhová rozhodnutí. A nakonec prezentuje implementovaný adaptér a jeho vyhodnocení pomocí automatizované testovací sady a pomocí experimentů s řadou analyzačních nástrojů. Nejvýznamnější ukazatel hodnocení vytvořeného adaptéru je to, že už teď je používán v praxi pro přidání OSLC rozhraní k nástrojům ANaConDA, Perun, Spectra (všechny tři vyvíjené na VeriFIT) a HiLiTE (Honeywell).

Full textAbstract:
Contracts for concurrency describe required atomicity of method sequences in concurrent programs. This work proposes a dynamic analyzer to verify programs written in Java against contracts for concurrency. The analyzer was designed to detect violations of parametric contracts with spoilers. The proposed analyzer was implemented as an extension to the RoadRunner framework. Support for accessing the method arguments and return values was added to RoadRunner as a part of the solution. The analyzer was fully implemented and verified on a set of testing programs.

Full textAbstract:
Finding concurrency bugs in complex software is difficult. As a contribution to coping with this problem the thesis proposes an architecture for a fully automated dynamic detection and healing of data races and atomicity violations in Java. Two distinct algorithms for detecting of data races are presented. One of them is a novel algorithm called AtomRace which detects data races as a special case of atomicity violations. The healing is based on suppressing a recurrence of the detected problem and can be performed by introducing an additional synchronization or by legally influencing the Java scheduler. Basically forces certain parts of the code to be executed atomically. The proposed architecture uses bytecode instrumentation to be able to track and influence the execution. The architecture and algorithms were implemented and tested on multiple case studies.

Full textAbstract:
In this work, we focus on improving the forest automata based shape analysis implemented in the Forester tool. This approach represents shapes of the heap using forest automata. Forest automata are based on tree automata and Forester currently has only a simple implementation of tree automata. Our first contribution is replacing this implementation by the general purpose tree automata library VATA, which contains the highly optimized implementations of automata operations. The version of Forester using the VATA library participated in the competition SV-COMP 2015. We further extended the forest automata based verification method with two new techniques - a counterexample analysis and predicate abstraction. The first one allows us to determine whether a found error is a real or spurious one. The results of the counterexample analysis is also used for creating new predicates which are used for the refinement of predicate abstraction. We show that both of these techniques contribute to an improvement over the early approach.

Konečný, Filip. "Relační verifikace programů s celočíselnými daty." Doctoral thesis, Vysoké učení technické v Brně. Fakulta informačních technologií, 2012. http://www.nusl.cz/ntk/nusl-261262.
Full textAbstract:
Tato práce představuje nové metody pro verifikaci programů pracujících s neomezenými celočíslenými proměnnými, konkrétně metody pro analýzu dosažitelnosti a~konečnosti. Většina těchto metod je založena na akceleračních technikách, které počítají tranzitivní uzávěry cyklů programu. V práci je nejprve představen algoritmus pro akceleraci několika tříd celočíselných relací. Tento algoritmus je až o čtyři řády rychlejší než existující techniky. Z teoretického hlediska práce dokazuje, že uvažované třídy relací jsou periodické a~poskytuje tudíž jednotné řešení prolému akcelerace. Práce dále představuje semi-algoritmus pro analýzu dosažitelnosti celočíselných programů, který sleduje relace mezi proměnnými programu a~aplikuje akcelerační techniky za účelem modulárního výpočtu souhrnů procedur. Dále je v práci navržen alternativní algoritmus pro analýzu dosažitelnosti, který integruje predikátovou abstrakci s accelerací s cílem zvýšit pravděpodobnost konvergence výpočtu. Provedené experimenty ukazují, že oba algoritmy lze úspěšně aplikovat k verifikaci programů, na kterých předchozí metody selhávaly. Práce se rovněž zabývá problémem konečnosti běhu programů a~dokazuje, že tento problém je rozhodnutelný pro několik tříd celočíselných relací. Pro některé z těchto tříd relací je v práci navržen algoritmus, který v polynomiálním čase vypočítá množinu všech konfigurací programu, z nichž existuje nekonečný běh. Tento algoritmus je integrován do metody, která analyzuje konečnost běhů celočíselných programů. Efektivnost této metody je demonstrována na několika netriviálních celočíselných programech.

Full textAbstract:
V dnešní době jsou vícevláknové programy běžné a s nimi i chyby v souběžnosti. Během posledních let bylo vytvořeno mnoho technik pro detekci takovýchto chyb, a i přesto mají vývojáři softwaru problém nalézt správné nástroje pro analýzu svých programů. Důvod je jednoduchý, fungující neznamená vždy praktický. Hodně nástrojů implementujících detekční techniky je obtížně použitelných, přizpůsobených pro konkrétní typy programů nebo synchronizace, nebo špatně škálují, aby zvládly analyzovat rozsáhlý software. Pro některé typy chyb v souběžnosti dokonce ani neexistují nástroje pro jejich detekci, i přesto že vývojáři softwaru na tyto chyby často narážejí ve svých programech. Hlavním cílem této práce je navrhnout nové techniky pro detekci chyb ve vícevláknových programech. Tyto techniky by měly být schopny analyzovat rozsáhlé programy, umožnit detekci méně studovaných typů chyb v souběžnosti, a podporovat širokou škálu programů s ohledem na to, jaké programové konstrukce používají.

Marková, Monika. "Finding groups of the similar variables with statistical software SAS and SPSS." Master's thesis, Vysoká škola ekonomická v Praze, 2007. http://www.nusl.cz/ntk/nusl-10417.
Full textAbstract:
My diploma thesis focuses on the comparison of possibilities of the statistical software SAS and SPSS in the area of the factor and cluster analysis and the multidimensional scaling. They deal with the methods for identifying groups of the similar statistical values (variables). The ascertained relations among the variables can serve to decrease the proportion vectors of the variables, which describe the individual monitored objects (statistical units), which helps us to apply other various methods, for example the regression or discriminant analysis. By one of the ways for finding the similarity of variables in the cluster analysis or the multidimensional scaling is searching for their relations. Whereas the base of the factor analysis is the formulation of the relation between two variables by means of the covariances, eventually Pearson correlation coefficient, it is possible to use also coefficients of correlation for the cluster analysis and the multidimensional scaling, in some case other measures. The thesis describes mainly the command syntax of the procedures implemented in SAS and SPSS. The meaning of the individual parametres and the partial specifications of each command are explained. The results gained by various types of analyses are compared on the basis of the real dataset. The possibilities of the statistical software SAS and SPSS are evaluated in the conclusion and it is referred to their advantages or disadvantages. The attention is also paid, for example, to the form of the input dataset, to the quaility of outputs or to the partial methods.

Full textAbstract:
This diploma thesis aims at the development of agile software projects of an existing company. The main goal of this dissertation has been to identify and analyze the most frequent current problems of the company, then to summarize their impact and to propose the best possible way of dealing with them. As an integral part, the aim of the dissertation has also been the creation of an internal knowledge base which can help to prevent those problems from happening in future projects and to share mutual experiences. To fulfil this goal, it has been necessary to learn all the problems of the agile software development, to know the most widely used agile methodologies and some latest facts and recent trends in the area of agile projects. It has also been necessary to carry out the SWOT analysis of the company and analyze the results of the internal agile development survey. The next thing which had to be done was the identification and description of the most frequent problems of agile development projects and the assessment of the categories of projects which occur in the company and linking the problems with each of the categories. The content of the internal knowledge base was created to correspond with the results of my diploma thesis. The contribution of this dissertation is the identification and assessment of the most fre-quent problems of agile projects of an existing company, identification of possible impacts and recommendation of possible solutions. The other contribution is the identification of the project categories which are linked to the identified problems. Last but not least, the main benefit of this thesis is the creation of a new internal project management knowledge base which will help to share the experience among all the projects and in this way it will help to prevent the spread of these problems. This diploma thesis is divided into two main parts, theoretical and practical. In the theoretical part, there is a definition of "agile methodologies", a description of their typical examples and statistics as well as modern trends in the area of the development of agile projects. The practical part is divided into four chapters. They contain the results of the company's SWOT analysis and the results of the internal agile development survey. Then there is a presentation of the identified agile development problems, their possible impact and the recommendation how to deal with them. There is a full description of all the identified categories of projects and their identified problems with their assessment criteria as well as time-proven ways how to effectively deal with them. The last chapter contains and internal project management knowledge base which has been done by myself. The knowledge base may be very useful in the project management now and in the future.
