Description
| - Fyzikálne experimenty vysokých energií v posledných rokoch napredujú smerom distribuovaného výpočtového modelu v snahe paralelizovať výpočty nad enormným množstvom dát, ktoré sa zvyšuje z roka na rok. Za účelom optimalizácie využitia všetkých dostupných zdrojov je potrebné čeliť i otázke efektívneho presunu a rozmiestnenia dát v distribuovanom prostredí. V tejto práci predstavíme model založený na programovaní s obmedzujúcimi podmienkami a reprezentáciu najdôležitejších vlastností reálneho prostredia. Budeme sa zaoberať i metódami zúženia prehľadávaného priestoru a predvedieme ich vzájomné porovnanie. Plánovač implementovaný za využitia knižnice Choco porovnáme tiež so simulátorom Peer-2-Peer siete. Na základe výsledkov sa použitie modelu zdá byť sľubné a dáva predpoklady na ďalšie rozšírenia.

- For the past decade, High Energy and Nuclear Physics experiments have been heading towards a distributed computing model in an effort to concurrently process tasks over enormous data sets, that have been increasing in size as a function of time. In order to optimize all available resources, it is necessary to face also the question of efficient data transfers and placements. In this work a model tackling this issue, based on Constraint Programming technique (CP) is introduced, as well as the representation of most important aspects of a real life scenario such as the sharing of infrastructure both when it comes to networking or storage. Methods for reducing a search tree and their side by side comparison are shown. Performance of scheduler based on Choco library is compared also with a Peer-2-Peer network simulator. Based on the preliminary results, using the CP model seems to be promising and gives good expectations for ongoing extensions.
