Abstract

Umrežavanje ugradbenih računalnih platformi sastojalo se od istraživanja i proučavanja uvjeta kako bi se program za izračun sažetka istovremeno pokrenuo na više platformi i kako bi platforme međusobno surađivale tijekom izvršavanja tog programa. Za pokretanje programa na distribuiranom sustavu, odabrana je MPI implementacija otvorenog koda, Open MPI. Takva MPI implementacija zahtijevala je i distribuirani datotečni sustav stoga je postavljen mrežni datotečni sustav (NFS) kako bi platforme imale pristup istim datotekama tijekom izvršavanja programa. Izmijenjen je i računalni kod programa John the Ripper (verzija jumbo) u svrhu distribuiranog izvršavanja programa i korištenja programabilne logike prilikom izvršavanja programa. Konačan rezultat rada je postignuta linearna skalabilnost prilikom dodavanja platformi u sustav.

Abstract (english)

The connection of embedded systems consisted of researching and studying the terms of how the password hashing program could be simultaneously run on multiple platforms and how those same platforms would interact between themselves during the execution of the program. Executing programs on distributed system was achieved using the open source MPI implementation – Open MPI. This implementation required a distributed file system, so for that purpose a network file system (NFS) was used. NFS provided access to shared files for all platforms during the program execution. John the Ripper (jumbo version) program has also been altered with the purpose of distributed program execution and use of a programmable logic during that execution. The final result of the thesis was linear scalability upon adding a platform into the system.
