Functional divisions in the Piglet multiprocessor operating system

Steve Muir, Jonathan Smith
1998 Proceedings of the 8th ACM SIGOPS European workshop on Support for composing distributed applications - EW 8  
These changes prompted the development of Piglet, an asymmetric multiprocessor operating system. Piglet partitions processors into functional groups in order to better utilise multiple processors.  ...  As multiprocessor computer systems become more commonplace, and peripherals are built with on-board CPUs, we believe that new operating system models are required to make the most e cient use of such systems  ...  Piglet applies the idea of functional division to partition work between itself and the general-purpose operating system (the host O.S.) which hosts users and applications.  ...

The ALIEN active loader provides safe access to these knobs to modules which operate on the network element.  ...  The Piglet lightweight device kernel provides a "virtual clock"-like scheduling discipline for network traffic, and exports several tuning knobs with which the clock can be adjusted.  ...  Acknowledgements We'd like to thank Bill Marcus for his help in writing some of the original ANEP code, and Mike Hicks for the discussions and tools he provided us for performance analysis.  ...

High‐intensity, focused ultrasonic fields

Leif Bjørnoø
1988 Journal of the Acoustical Society of America  
The maps of energy propagation, sound pressure and particle velocity, as well as the formation of vortices, will be shown. Specific applications in many areas of acoustics will be summarized.  ...  Radiation and propagation of sound energy represents fundamental knowledge in all subfields of acoustics and vibration.  ...  a multiprocessor configuration.  ...

more even division of labor between application and network processors of the former approach, (ii) the benefits of SMP and cluster-based TCP servers reach 18% and 30% respectively, in the scenarios we  ...  TCP Server is a system architecture aiming to offload network processing from the host(s) running an Internet server.  ...  We study the impact of separation of functionality not only for a bus-based multiprocessor system, but also for a switch-based cluster of dedicated processors.  ...
