Performance Analysis of Distributed Data Base Systems
In this paper we briefly present the design of a distributed relational data base system. Then, we discuss experimental observations of the performance of that system executing both short and long commands. Conclusions are also drawn concerning metrics that distributed query processing heuristics should attempt to minimize. Lastly, we comment...

Distributed Data Mining in Peer-to-Peer Networks
Distributed data mining deals with the problem of data analysis in environments with distributed data, computing nodes, and users. Peer-to-peer computing is emerging as a new distributed computing paradigm for many novel applications that involve exchange of information among a large number of peers with little centralized coordination. Peer-to-peer file...

Applying Mainframe Experience to the Distributed Environment
Mainframes and distributed systems, previously looked at as separate entities, are now rapidly coming together into a single, distributed IT environment. As a result, people from two previously separate and very different cultures - mainframe and distributed - are coming together to architect, develop, and manage the resulting unified infrastructure....

Proportional Service Allocation in Distributed Storage Systems
Fully distributed storage systems have gained popularity in the past few years because of their ability to use cheap commodity hardware and their high scalability. While there are a number of algorithms for providing differentiated quality of service to clients of a centralized storage system, the problem has not been...

Towards a Multi-Perspective Assessment of Scalability of Distributed IT Services
Scalability is an important issue in distributed IT service design and should be addressed at least from technical and economic perspectives. The paper presents a conceptual framework that addresses scalability from these two perspectives. To explore scalability of distributed services, the framework employs a value model and UML deployment model...

Short Paper: Troubleshooting Distributed Systems Via Data Mining
Through massive parallelism, distributed systems enable the multiplication of productivity. Unfortunately, increasing the scale of available machines to users will also multiply debugging when failure occurs. Data mining allows the extraction of patterns within large amounts of data and therefore forms the foundation for a useful method of debugging, particularly...
