Abstract: |
In the dissertation we focus on the topic of distributed shared memory (DSM) in modern operating systems. We take into consideration new operating systems, usually based on the microkernel architecture, as well as existing industry-standard operating systems and their middleware services. Concerning DSM, we try to figure out its desired capabilities and attributes in order to be able to build medium- to large-scale distributed applications. The results of the dissertation can be summarized as follows:
1.We have designed a microkernel for distributed operating systems with DSM as its key communication abstraction.
2.We have designed a tool for exploring and evaluating networked systems on a single host by making modifications to the kernel of an existing operating system and introducing the concept of virtual hosts.
3.We have designed a memory coherence protocol offering causally consistent DSM using IP multicast for coherence traffic.
4.We have developed an application of the designed coherence protocol by building a DSM using the .NET Framework.
