....Inc. 2 Symposium on Microkernels and Others Kernel Architectures USENIX Association 1. Introduction The technology of distributed systems [1] 2] has grown and matured since the early eighties [3]. Today it is used to support applications based on the UNIX 1 operating system interface [4] 5] and also new features such as lightweight processes and Inter Process Communications with message passing. Over the same period personal computers became widely used. These computers offer graphical ....

....the Synthesis emulator of UNIX carries very low overhead (because of dynamic code generation) Modular kernels with abstract interfaces . Apertos and other kernels that have a completely abstract interface. Mention the implementation limitations of these kernels. Other modular kernels. Chorus [7] and Mach [1] Contrast between a pure message based implementation (Mach) and a multiple implementation kernel (Chorus) If possible, show the cost of a modular kernel without dynamic code generation. Maybe talking to Apple people (Finlayson) Discuss the use of dynamic optimization, such as ....

....thread scheduler including multiple scheduling policies, real time synchronization mechanisms and a memory resident memory object manager. 2.1. 2 Chorus The Chorus microkernel is a capability based operating system developed by Chorus Syst emes in France and based on earlier research in INRIA [103]. Chorus has an objectoriented design and is written in C . The Chorus microkernel is designed with distribution and efficiency as its primary goals [89] The abstractions used to represent processing entities in Chorus are called actors and threads. Actors are tied to a given site and define an ....

.... memory system can be used to improve efficiency of message transmission within a site, by mapping pages out of one address space and into the other [89] Unlike the Mach microkernel, Chorus was developed with an emphasis on distribution in environments with networks of loosely coupled processors [79, 103]. Distribution is integrated at the lowest levels of Chorus. Chorus also provides the notion of port groups. Port groups enable a process to send a message to a group of ports providing a service, to any one member of the group, or to a service provider on a particular node. The units in the ....

....by existing systems. 6 Related Work Many of the individual optimization techniques and kernel structuring ideas discussed in this paper have been studied in other contexts. Coarse grain modularity has been studied in the context of microkernel based operating systems such as Mach [1] Chorus [33] and V [9] Mach, for example, offers an encapsulated kernel, in which kernel resources and services are hidden behind a port message based interface [5] The facilities that allow dynamic linking and loading of servers into the address space of a running Chorus kernel are also related to our ....
