Topia!: Computers: Software: Operating Systems: Parallel (5)
See Also:
PEACE - Process Execution And Communication Environment: OS family, true object-oriented design, from GMD FIRST. Emphasis: performance, configurability, portability. Originally part of research on massively parallel systems, showed promise for other uses, became basis for several projects at FIRST and elsewhere. Paramecium - Simple, flexible, adaptable, extendable, object-based microkernel OS; goals: support parallel programming and explore tradeoffs between user processes and kernel boundaries. Services provided by objects named in a per process name space. Cosy - Goal: scalability of highly parallel multicomputer systems. Based on small microkernel that does process management, interprocess communication; all other services are processes out of kernel. Processes and address spaces orthogonal, so Cosy process is like thread in other OSs. Hardware dependencies concentrated in areas of kernel for portability. Parallel Systems Group - University of Toronto researchers working on all aspects of parallel systems: computer architecture, OSs, compilers, performance evaluation, applications. Home of Hurricane and Tornado OSs, Hector and NUMAchine multiprocessors.
