Sparse matrices are pervasive in many Computational Science and Engineering (CS&E) applications. There is a significant number of storage formats used to represent sparse matrices. This paper presents a performance evaluation of storage formats for the main kernel of iterative methods for numerical linear algebra, namely matrix-vector multiplication.(More)
Data replication is an important research area, as reliable access to data makes up the base of most of IT services. High operation availabilities, low operation costs and data consistency are major target conflicts in almost every data replication research. In this paper, we introduce a data semantics and data encoding-based data replication strategy(More)
Cyber physical systems are complex systems which monitor, sense or interact with the environment, gather information with the help of different types of sensors or mobile devices, propagate the sensed data to a processing unit via WAN, LAN, MANET, VANET or overlay network, the processing unit process, analyze and store the received data, and based on the(More)
