Abstract

Fine-grained process synchronization methods in multi-processor distributed memory systems with time- constraint centralized control are discussed in the paper. Synchronization methods are presented which enable a non-blocking synchronization of processes in many processor clusters in parallel for the needs of a global control subsystem. They can be used for efficient synchronization of processes in programs with non-deterministic control structures. The proposed solutions are applied for the control of parallel programs execution according to a new paradigm. It is based on the dynamic look-ahead inter-processor connection setting and assures time transparency of connection reconfiguration control during program execution.
