CS Other Presentations

Department of Computer Science - University of Cyprus

Besides Colloquiums, the Department of Computer Science at the University of Cyprus also holds Other Presentations (Research Seminars, PhD Defenses, Short Term Courses, Demonstrations, etc.). These presentations are given by scientists who aim to present preliminary results of their research work and/or other technical material. Other Presentations serve as a forum for educating Computer Science students and related announcements are disseminated to the Department of Computer Science (i.e., the csall list):

Abstract:
A distributed shared storage (DSS) space is a fundamental service to ensure availability, survivability and accessibility to cloud data. A major challenge in DSS is to maintain consistency when data may be accessed concurrently by multiple processes. COLLABORATE had the goal to develop shared storage solutions, that provide strong consistency guarantees, while supporting large data objects, and tolerating a number of host failures. To achieve efficiency of the service we introduced fragmentation strategies of the large objects and examine how those techniques may affect the consistency of the object. To accommodate host failures, we proposed the use of two external services: (a) a storage device monitor, called Drivenest (www.drivenest.com), which is able to present the status of storage devices and predict soon-to-fail drives, and (b) a reconfigurable service that replaces failing hosts without interrupting the normal operation of the DSS. We implemented and deployed the proposed solutions in both emulated and read time environments. We run various experimental scenarios and put our solutions into the test. Our outcomes will be presented and analysed to question the applicability of such solutions into practical settings.
