Abstract: |
Private Virtual Cluster (PVC) is middleware project targeted to “Instant Grid”. It can be defined as
combination of Grid, P2P and VPN approaches targeted to allow simple deployment of distributed
applications over different administration domains. It is currently under development. The target
system will be fault-tolerant, scalable, autonomous, and dynamic. PVC is actually a Peer To Peer (P2P)
network serving Grid/Parallel application. It relies on two different entities: a software peer and a
resource broker. After a general overview of PVC this presentation will show the design of the
distributed brokering system. It performs a set of operation as the peer enrollment in the virtual
network, the peer lookup and several others. Its design is based on a Distributed Hash Table (DHT) and
an overview of the functionalities of DHTs will also be shown. The DHT is used as distributed data
structure and another component is delegated to interact with the actual peer. A reference Java
implementation of the broker is currently under debugging. The test phase will be performed on
Grid5000. Finally, the immediate future works include the addition of a resources reservation system. |
Bio: |
Roberto Podesta' was born
in Genoa in 1977. He got a Ph.D. in Computer Science and Communication
Technology from the University of Genoa in 2007. In the same university
he served also as research assistant, lecturer, and associate
researcher. During his activity he cooperated with the GRIDS Lab
of the University of Melbourne (Australia) and with some industrial
research division of enterprises as Telecom Italia and Marconi-Ericsson.
In October 2007 he joined the Grand-large project at the INRIA
section in Orsay (France) as research fellow supported by the
European Research Consortium for Informatics and Mathematics (ERCIM). His main research interests include distributed and heterogeneous computing systems and technologies, and, in particular, Peer to Peer architectures, Grid-, and Autonomic- Computing. |
