Computer Network Department IFP SB RAN was founded in 1997 on the base of Computer Systems Library created in the middle of 1960 years. In the collective of the Department a conception of computer systems (CS) with programmable structure was formulated. Main subjects of scientific and applied investigations of the Department are: potential and structural robustness of distributed scalable multiprocessor systems; system selfdiagnostics of distributed CS with multiple failures; fault-tolerant parallel algorithms of information processing in CS with massive paralllelism; system and applications software of robust distributed computer systems and networks.
