Zusammenfassung:An integrated software architecture for a highly parallel multiprocessor system having multiple tightlycoupled processors (10) that share a common memory (14) efficiently controls the interface with and execution of programs on such a multiprocessor system. The software architecture combines a symmetrically integrated multithreaded operating system (1000) and an integrated parallel user environment (2000). The operating system distributively implements an anarchy-based scheduling model for the scheduling of processes and resources by allowing each processor (10) to access a single image of the operating system (1000) stored in the common memory that operates on a common set of operating system shared resouces (2500). The user environment (2000) provides a common visual representation for plurality of program development tools that provide compilation, execution and debugging capabilities for multithreaded user programs and assumes parallelism as the standard mode of operation.
