DCSN: Platform for Distributed Computing in Small Networks
Háva, Jakub ; Marek, Lukáš (advisor) ; Falt, Zbyněk (referee)
This thesis describes the platform for distributed computing in small networks. The platform should be very easy to use and suitable for deployment typically in one local network. The implementation follows the client-server architecture and the communication between client and server is based on Remote Method Invocation. The server is responsible for tasks distribution and other computation management. The client receives commands from a user, mediates communication with the server and is also used for the processing of tasks received from the server. The user submits a computation project consisting of two parts: a zip archive containing data files and a JAR archive containing a configuration file together with Java classes needed for the computation on the user data. The user is allowed to query the project state, pause, download or abort the project computation. Powered by TCPDF (www.tcpdf.org)

Monitoring Tool for Distributed Java Applications
Háva, Jakub ; Parízek, Pavel (advisor) ; Hnětynka, Petr (referee)
The main goal of this thesis is to create a monitoring platform and library that can be used to monitor distributed Java-based applications. This work is inspired by Google Dapper and shares a concept called "Span" with the aforementioned project. Spans represent a small specific part of the computation and are used to capture state among multiple communicating nodes. In order to be able to col- lect spans without recompiling the original application's code, instrumentation techniques are highly used in the thesis. The monitoring tool, which is called Distrace, consists of two parts: the native agent and the instrumentation server. Users of the Distrace tool are supposed to extend the instrumentation server and specify the points in their application's code where new spans should be created and closed. In order to achieve high performance and affect the running appli- cation at least as possible, the instrumentation server is used for instrumenting the code. The Distrace tool is aimed to have a small foot-print on the monitored applications, should be easy to deploy and is transparent to target applications from the point of view of the final user. 1
