Efficient Techniques for Program Performance Analysis
Pavela, Jiří ; Fiedor, Jan (referee) ; Rogalewicz, Adam (advisor)
Tato práce představuje optimalizační techniky zaměřené na proces sběru výkonnostních dat v rámci výkonnostní analýzy a profilování programů v nástroji Perun. Rozšíření architektury a implementace těchto nových optimalizačních technik v nástroji Perun (a převážně pak v jeho modulu Tracer) zlepšuje jeho škálovatelnost a umožňuje tak provádět výkonnostní analýzu i nad rozsáhlými projekty. Zaměřujeme se především na zvýšení přesnosti sběru dat, redukci množství instrumentovaných bodů programu, omezení časové režie procesu sběru dat a výkonnostního profilování, snížení objemu sbíraných dat a velikosti výsledného výkonnostního profilu. Optimalizace je dosažena pomocí aplikace statistických metod, množství technik statické a dynamické analýzy (případně jejich kombinací) a využitím pokročilých možností a schopností nástrojů SystemTap a eBPF. Na základě vyhodnocení provedeného na dvou vybraných projektech a množství experimentů můžeme konstatovat, že se nám úspěšně podařilo dosáhnout značné optimalizace u téměř všech sledovaných metrik a kritérií.

Server for Continuous Integration
Šajdík, Michal ; Fiedor, Tomáš (referee) ; Lengál, Ondřej (advisor)
Tato práce obsahuje popis následujících témat: jaké technologie a principy jsou potřebné pro vytvoření kontinuálního integračního serveru, již existující řešení, proč je potřeba jeden vytvořit a jak integrovat kontinuální integrační server, který byl vytvořen během této práce, na základě informací uvedených v této práci, do pracovního prostředí. Tato práce také ukazuje efekty a některé vedlejší účinky způsobené správnou a nesprávnou konfiguraci uvedeného serveru pro kontinuální integraci. Uvedený server pro kontinuální integraci je také schopen běžet na MS Windows 10 a Linuxu, aniž by bylo nutné přizpůsobit konfiguraci pro konkrétní operační systém.

Usage of automated regression tests in continuous integration of web application
Kolpakova, Alexandra ; Buchalcevová, Alena (advisor) ; Veselka, Marcel (referee)
This bachelor thesis focuses on the implementation of automated regression tests into the practice of continuous integration in the development of a web application. The main goal of the bachelor thesis is to design and implement a system of continuous integration including testing for the purpose of deploying a web application on the test environment. Specific objective is to characterise the concept of continuous integration, exploration of principles and practices of continuous integration, characteristics of regression tests and the process of automation of test cases, design of system for use of continuous integration and consequently its practical verification. The theoretical part of the thesis is focused on the introduction to the practice of continuous integration, its characteristics and principles. The following section describes the testing process, especially different levels and types of tests. The practical part introduces a proposed system for the use of continuous integration in software development. It continues with analysis and design of test cases processed according to the functionality of the web application. The implementation of the proposed system is followed by the implementation of automated tests. The output of the thesis is the elaborated scheme for automated deployment of the web application on the test environment in the practice of continuous integration and a usable resource containing the procedure for implementing regression tests into the process of continuous integration.

Virtualization utilization for automatic infrastructure creation for web application testing
Nepejchalová, Radka ; Vasilenko, Alexandr (advisor) ; Rostislav , Rostislav (referee)
The main aim of this thesis is to approximate some of the currently used techniques and principles within software development. Nowadays, great emphasis is placed on efficiency and quality of teams. Adopting the principles of continuous integration brings multiple benefits, especially for complex projects where many developers work at parallel. There is a greater need to integrate increasing generated code and make sure that the newly formed unit keeps functional. One of the main principles of the continuous integration is regular testing possibly revealing the problems that might occur during production deployment. However, such testing can be very expensive and using virtualization can be the key to reduce these costs. Testing new versions of applications can be made very easily using virtualization. Part of the work is devoted to all these previously mentioned parts. The practical part is then devoted to demonstrate solutions of real problems.

Software Development with Continuous Delivery
Molnár, Dávid ; Rychlý, Marek (referee) ; Křivka, Zbyněk (advisor)
Purpose of this work is to make the reader familiar with the principles of Continuous Delivery. Among them belongs automated deployment, frequent and repeatable delivery, versioning of applications and infrastructures configuration. These principles allow the develop-ment team to deliver the product very effective and ensure that customers get the ordered product in time and the fastest way possible. In the focus is the Windows platform, automatization and encryption of sensitive data. We will learn how to solve the problem of versioning relational databases and how to ensure working migration of database schema and data. Part of the work is a description, how to introduce Continuous Delivery in a team.

Continuous Integration System for the k-Wave Project
Nečas, Radek ; Kešner, Filip (referee) ; Jaroš, Jiří (advisor)
The main goal of this thesis is to describe the implementation of continuous integration into the k-Wave project. The thesis focuses primarily on the version written in the C/C++ language with the usage of the OpenMP library which typically runs on supercomputers. Accordingly, many of popular workflows and approaches ought to be adapted, a few more created. The outcome of the thesis is a complete solution with real and practical usage. The author provides design, tools selection, runtime environment administration and configuration for each one of the used services. Software implementation of the basic framework is used in order to utilize running tests on the supercomputers. Furthermore, the implementation of chosen types of regression and unit tests are performed. Realisation is based on Gitlab and Jenkis services that are running on separated Docker containers.

Dynamic Workflow Extension for Jenkins
Sviták, Jiří ; Burget, Radek (referee) ; Letko, Zdeněk (advisor)
The main of the master's thesis has been to implement a plugin for Jenkins, which enables flow control of launching Jenkins jobs by using business processes. Project jBPM 5, which is based on Business Process Model and Notation 2.0, has been used for business processes. Two sample business processes have been drafted and successfully tested to demonstrate functionality. The main output of this thesis is the jBPM plugin for Jenkins released under free license.

Integration of Jenkins CI with Undertow
Barteček, Jakub ; Letko, Zdeněk (referee) ; Müller, Petr (advisor)
This master's thesis deals with replacement of the servlet container in Jenkins CI with server Undertow. In the thesis, general information about programs, which are related to this topic, are described and current state of the servlet container is analyzed. The result is newly created servlet container for Jenkins CI. Both versions of the Jenkins CI were performance tested and the new version gave better results.
