Parallel implementation of fine-grain algorithms in WinALT system

A brief description of a simulation system for algorithms and structures with fine-grain parallelism WinALT is given. The distinguishing features of the system are a visual construction and debugging of models as well as its orientation to a wide range of algorithms and structures with fine-grain parallelism rather than only to a cellular automaton along with its certain extensions. The existing subsystem of parallel execution, which is capable to execute models using a cluster of Windows hosts, is considered. The requirements to a new implementation of the subsystem for parallel execution are formulated. This new implementation is oriented to a wide range of modern parallel computers including hybrid clusters. The architecture of the subsystem is proposed. Its modes of parallel execution are considered. The plans of further development of the system are outlined.
