Software and hardware failures may lead to loss of valuable data. Replication, is indinsbensable in ensuring data survaivability and availability. Data is replicated among multiple basic storage units - servers or disks. Although replication copes with loss of data, it fails to provide consistency guarantees when multiple processes access different replicas concurrently. To assess the state of the replicated data, researchers proposed various levels of consistency semantics. Atomicity is the strongest and most precise consistency semantic, and therefore the most difficult to supply in a distributed, asynchronous, failure prone setting.

Several solutions proposed atomic read or write storage implementations. However, the inherent complexity of atomicity led these approaches to incorporate excessive communication between the clients and the data replicas, deteriorating the operation latency of every read or write operation. This project investigates the operation latency of read and write operations of atomic register implementations that support multiple writers and multiple readers (MWMR). Such implementations comprise building blocks for more complex Distributed Storage Systems (DSS). Also, they can be used directly to implement distributed file systems, which are interesting on their own right.

In summary this work aims to investigate:

(a) Is it possiple to devise algorithms implementing MWMR atomic registers with low operation latency?

(b) What is the practicality of such algorithms in the context of experimental simulations and implementations in planetary scale networks?

Welcome

Welcome to the website of the Department of Computer Science at the University of Cyprus. The Department has experienced significant growth over the last few years with strong groups in artificial intelligence, computer architecture, computer networks, data management, graphics and virtual reality, internet computing, software engineering and theoretical computer science. The Department offers a Bachelor degree in Computer Science with 7 different specializations as well as a number of Master degrees and a Ph.D. degree in Computer Science.

The Department has a strong research infrastructure comprising high-performance clusters and storage area networks, cloud computing facilities, smart-phones and sensing devices and virtual reality equipment. Since 2005, our Department has been involved in more than 160 research projects funded from both the European Union and the Cyprus Research Promotion Foundation with total funding of over 21.5 million euros.
