Abstract:V tem diplomske delu smo preverili uporabo razpršenih omrežij za namen vzporedne obdelave kombinacijskih problemov, ki so definirani s Catalanovimi števili. Osredotočili smo se na razpršena omrežja na javanski platformi z uporabo principa razmreži/privedi z ogrodjem GridGain. Razvili smo več vzporednih algoritmov za preiskovanje iskalnih prostorov, katerih velikost je določena s Catalanovim številom (Catalanov prostor). Pri tem smo uspeli doseči vidno pohitritev izvrševalnega časa preiskovalnega algoritma. Pri naših meritvah je največja pohitritev znašala , pri na vozliščih. Dodatno smo predlagali drugačen pristop k delitvi opravil na vzporedno izvajajoče se posle in izenačevanju obremenitve.

Title:GRID COMPUTING AND ITS APPLICATION ON COMBINATORIAL PROBLEMS
Abstract:In this thesis we investigated the use of grids for parallel processing of combinatorial problems defined by Catalan numbers. We focused on java grids using the (Google) map/reduce paradigm with the GridGain open cloud platform. We implemented several parallel algorithms for conducting a search sweep of the problem spaces defined by Catalan numbers (Catalan space). We managed to achieve a noticeable search algorithm speedup with a maximum factor of , at on grid nodes. We also suggested an alternative approach to grid load division and balancing.
Keywords:grid computing, parallel processing, map/reduce, java platform, combinatorics, Catalan numbers
