What is the future ...

Collaborative working ...
Grids for Complex Problem Solving , 29 January 2003
• Networks– need good connectivity at “low” price
– QoS is a mandatory feature (need to dedicate BW according to criticality of data streams i.e. video or RT needs)
• Grid Middleware– security is probably the most important issue in the
context of VOs
– but directory services, data management, scheduling and brokering are obviously important (eBusiness)
Anatomy of the system ...

• Applications– at the client level: need for light client (mobile
users)
– applications coupling (soft/soft or soft/hard) requires some specific middleware
• data-fusion
• data-mining
– powerful GUI• 3D RT capabilities
• multi-modal GUI
Anatomy of the system ...

• Current grids are static, need to be more dynamic– virtual organization can be O(2) to O(1000)
– lifetime from minutes to years
– admin policies shall cross the domains
– dynamic behavior (membership, status, …)
– scalable in term of administration
– resource discovery
– innovative license management policy

• Security is a MAJOR concern
– how to efficiently protect our data while granting specific access to our resources to providers/suppliers ?
– need to have a fine grain access policy while granting access to community that can be large

“Research” issues
Grids for Complex Problem Solving , 29 January 2003
– Manageable (interoperable/scalable) security solutions for VOs
– Need for a set of standard industrial applications (e.g. CAE, PDM, 3D imagery) to be “gridified” (vertically integrated) with grids (the foundations are there, but the applications aren’t using them!)
– Need for generic enabling VO services such as community accounting & billing services and industrial strength basic collaboration services

– WANTED: distributed operating systems “à la” Mosix or Kerrighed. A “Grid Virtual Machine” providing a compact & common set of protocols !
– Convergence of Grid computing & cycle stealing approach (more than P2P) in order to accommodate high performance collaborative applications
– Integration of Knowledge Based Engineering tools within generic/specific Grid based Problem Solving Environments

Questions ?
Is your company already
using Grid technologies ?
Are your design processes collaborative
& made of multiple participants ?
What do you see as the main
barrier for using Grid computing ?
