1. Application of Parallel Computing to the Simulation of Chaotic Dynamics AndrewKostousov, Ural State University

2. Forest-Fire model – empty site – tree

3. What do we need for model investigation Perform simulation on large fields To increase the ‘resolution’ of the model Obtain very long time series To discover the laws of rare events

4. Why to use parallel computers Large fields do not fit in memory of a single processor Acquisition of long time series using single processor takes impermissible amount of time
