Presentation of UTIC Laboratory
The Research Unit of Technologies of Information
and Communication (UTIC) of the University of
Tunis is created in 2000. The activities of UTIC
are  focused  on two main topics      
E-learning and e-accessibility
High performance and  grid computing

Research Topic 1
E-learning and e-accessibility

• Improve efficiency of e-learning tools and
  environments
• ? PERSO project automatic personalization of
  courses in e-learning systems
• Create a barrier-free learning environment for
  students with disabilities.
• improve accessibility to ICT of people with
  disabilities and special needs.
• ? WEBSIGN project an environment for
  communication with deaf people using sign
  language via the web.

Research Topic 2
High performance and  grid computing

• Parallel algorithms and scientific applications
• Grid and peer to peer technology
• Middleware and algorithmic for grid computing
• Deployment of large scale applications

Objectives of GTRS (1)

• Deploy an academic Tunisian Grid for Scientific
  Research.
• An infrastructure to federate resources between
  Tunisian researchers based on Peer to peer
  Technology.
• Exploit resources available in academic
  institutions (generally under used).
• Create an experimental platform for research and
  the multidisciplinary cooperation between
  researchers.

Objectives of GTRS (2)

• Offer to Tunisian researchers a set of computer
  resource geographically dispersed.
• A power of calculation, an enormous
  storage space and many services always
  available. 
• Exploit the power of calculation of a big number
  of computers in order to give the illusion of a
  very powerful virtual computer.
• Encourage the large scale experimentation,
  validation of the research works and theoretical
  models proposed by the researchers.

Peer to Peer systems

• Definition1 of a P2P system
• peer-to-peer computing is the sharing of
  computer resources and services by direct
  exchange between systems .
• Definition 2
• peer-to-peer refers to a class of systems and
  applications that employ distributed resources to
  perform a critical function in a decentralized
  manner.

Peer to Peer systems

• Characteristics
• The peer-to-peer concerns a class of
  applications which require hardware or human
  resources available on the Internet.
• ? Two types of peer-to-peer systems
• 1) Files sharing systems such as Gnutella,
  Napster and Kazaa, which knew a great success on
  Internet
• 2) Intensive computation oriented systems,
  equivalent to computational grids, such as
  SETI_at_Home and XtremWeb.

Architecture of GTRS (1/3)

• GTRS Grid computing based on Peer-to-Peer System
• Middleware XtremWeb-CH
• Architecture different from EumedGRID
• Composed of 3 fundamental elements
• Coordinator
• Relay
• Worker

Recent research

• Interoperability between GTRS and EumedGrid

21
Needs of interoperability

• Convergence of peer-to-peer and Grid computing is
  a natural outcome of recent distributed systems
  philosophy.
• Based on the mutual benefits that Grid and P2P
  systems seem to offer to each other
• The two approaches will eventually converge,
  especially when Grids reach the "inter-grid".

21
22
Interoperability

• This integration can improve the two platforms by
  offering the possibility to support users
  applications, initially designed to be deployed
  on GTRS (resp. EumedGrid) to be run on EumedGrid
  (resp. GTRS).
• This task will integrate the resources used
  locally in GTRS to the whole EumedGrid.
