Objective The aim of this project is to undertake large-scale Monte-Carlo(MC) simulations using various types of computing equipment, including special purpose computers designed and constructed at Moscow, and Delft as well as large-scale computer facilities in Jülich and Delft. In particular, the prototype computer at the Landau Institute, implementing a very efficient cluster-flip MC algorithm (Wolff algorithm) for lattice models with discrete degrees of freedom (such as Ising models), is based on a new type of architecture with a very high performance/cost ratio. That machine is used to study critical slowing down in pure and dilute models, and critical phenomena in random Ising models. With a 'complementary' workstation at the Landau Institute, various tasks can be performed, such as testing of the algorithm implemented on the special purpose computer, visualization of results, data analysis and other numerical investigations. Experiences obtained with that machine will be applied in constructing a new special purpose computer to obtain highly accurate results on the three-dimensional Ising model, especially near its critical point. Those activities will be complemented by the know-how of the Delft group in designing and running special purpose computers, including experience with various random number generators. An on-going co-operation with mathematical physicists in St. Petersburg on that topic is to be integrated into the joint research in the future. In particular, in the joint research project, supposedly good shift register random number generators are tested to identify possible hidden correlation.The outstanding computer facilities of the Jülich Research Centre and Delft Technical University will be used for complementary testing of algorithms and for exploring a wide range of simulation applications in fields such as surface physics and superconducting materials.
