Salvatore Distefano received, in October 2001, the master's degree in computer engineering from the University of Catania. In 2006 he achieved the PhD degree on advanced technologies for the information engineering from the University of Messina. His research interests include stochastic modeling, performance evaluation, reliability techniques, parallel and distributed computing and software engineering. During his research activity he participated to the development of the WebSPN, ArgoPerformance and GS3 tools. He has been involved in several national and international research projects. He is member of international conference committees and he is on the editorial boards of several international journals on dependability and distributed computing topics. At this time, he is an assistant professor at Politecnico di Milano. He is a member of the IEEE.
Antonio Puliafito is a full professor of computer engineering at the University of Messina, Italy. His interests include parallel and distributed systems, networking, wireless and Cloud computing. He has contributed to the development of the software tools WebSPN and ArgoPerformance. He is coauthor (with R. Sahner and K.S. Trivedi) of the text entitled Performance and Reliability Analysis of Computer Systems: An Example-Based Approach Using the SHARPE Software Package, edited by Kluwer Academic Publishers. He is also the responsible of two big Grid Projects (TriGrid VL and PI2S2) funded by the Sicilian Regional Government and by the Italian MIUR, respectively. He is currently a member of the general assembly and of the technical committee of the Reservoir and Vision, IP projects funded from the EU to explore the deployment and management of IT services and data across different administrative domains. He is also the main investigator of the Italian PRIN2008 project Cloud@Home, trying to combine cloud and volunteer computing. He is a member of the IEEE.
Kishor S. Trivedi holds the Hudson Chair in the Department of Electrical and Computer Engineering at Duke University, Durham, North Carolina. He was the Duke-Site Director of an National Science Foundation Industry-University Cooperative Research Center between NC State University and Duke University for carrying out applied research in computing and communications. He has served as a principal investigator on various AFOSR, ARO, Burroughs, DARPA, Draper Lab, NEC, IBM, DEC, Alcatel, Telcordia, Motorola, NASA, NIH, ONR, NSWC, Boeing, Union Switch and Signals, NSF, Cisco, Huawei, NATO, JPL and SPC funded projects and as a consultant to industry and research laboratories. He was an editor of the IEEE Transactions on Computers from 1983-1987. He was on the editorial board of the IEEE Transactions on Dependable and Secure Systems. He is a codesigner of NASA's HARP, IBM's SAVE, SHARPE, SPNP, Boeing's IRAP and SREPT modeling packages. He is the author of a well known text entitled, Probability and Statistics with Reliability, Queuing and Computer Science Applications. He is a fellow of the IEEE.
