TNGrid : Tunisian National Grid
The TNGrid project is an initiative of the
research lab. of Technologies of Information and
Communication (LaTICE) at the Higher School
of Sciences and Technology of Tunis (ESSTT) of
the University of Tunis
TNGrid offers an open and free Tunisian National
Grid for researchers
The grid computing platform is based on
institutional resources and volunteer
participations.

participating in EUMEDGRID projects
coordinated by INFN (Italy) since 2006 .
We have a Registration Authority, managed
by Mohamed Jemni, with INFN CA
We are setting up the TNGrid CA
(Certification Authority) and to be fully
operational just after our accreditation
process with EuGridPMA.

Interoperability of clouds
Various criteria
Description and application deployment:
various APIs owners!
Architecture: centralized, hierarchical &
distributed
Mechanisms of resource management: access
to resources and task scheduling.
Security: multiple security mechanisms
How to normalize all these criteria?

SLA management
(Auto Trader)
SLA: Service Level Agreement, a contract
agreement between the client and service
provider
The step of negotiation is necessary between the
client and supplier
Research
New Scheduling models taking into account economic
constraints
Auto traders to establish the negotiation phase
