In order to provide location-transparent remote execution, Sprite associates with each process a distinguished home node, which provides kernel services to the process throughout the process's lifetime.
Based on the measured performance results, the SPIRIT-μKernel architecture is practical and appealing due to its low overheads of kernel services and the support for dependable integration of real-time applications via scheduling algorithm.
Traditionally the course emphasizes classical operating systems topics: concurrency, facilities for storage, communication, and protection, kernel services and structure, architecture/OS interaction, distributed systems, and practical application of operating system concepts in real operating systems.
host_get_clock_service - Return a send right to a kernel clock's service port.
The design goals for the Blue Matter architecture include separating the complexities of the parallel implementation on a particular machine from those of the scientific simulation as well as minimizing system environmental dependencies so that running an application within a low overhead kernel with minimal services is possible.
There are different approaches for configuring and composing unbundled DBMS services: kernel systems, customizable systems, transformational systems, toolkits, generators and frameworks [40].
We discuss the deployment of this network on the city kernel and some related services exposed to urban actors.
We describe a variety of interesting and significant ways in which triggers have been put into practice, and we classify trigger applications along two dimensions: "handcrafted" versus "generated", and "kernel DBMS" versus "DBMS services" versus "external applications".
Monolithic kernels implement all the services in the kernel, while microkernels have a small kernel combined with user daemons implementing services.
