2. Agenda Mobile grid features User & instrumentation requirements
RINGrid project overview, current status and identified instrumentation
Prototype & requirements verification
Network infrastructure
Future possible areas of cooperation with EU-Indian partners

3. Mobility in grid
“Anytime, anywhere” access to resources available in the grid
Mobile Grid is a platform that should address mobility issues:
Mobile user Fixed grid resource
Fixed user Mobile grid resource
Only remote access to rare and high-value instrumentation considered

4. General architecture Thin client Java & web browser required only
Scenarios submitted using SSA application
All computations on the „server” side – transparently for user

5. Mobility & interactivity
Thin client
Java & web browser required only
Scenarios submitted using SSA application
All computations on the “server” side
Data stored in Digital Library (data sharing)
Support for interactive tasks
Separate secure VNC (Virtual Network Computing) session manager for every application serving instrument
User session sustainability
Compression of the VNC session images for low quality connections

6. Security Implemented solutions Web site access through HTTPS protocol
WS based security through encoding SOAP (Simple Object Access Protocol) messages
User certificates and proxy authentication policy
Existing policies
DMS (Data Management system) policy for access to data repository and digital library
GAS (Grid authorization service) with built–in RAD (Resource Access Decision) – authorization security model
RAD example policy: getAuthorizationDecision (User, Resource, Submit job)

7. Scenario submission application
VLAB version
EXPReS project example

8. EXPReS Telescopes are usually separated by thousands of kilometres
VLBI is a technique, in which physically independent and widely separated radio telescopes observe the same region of sky simultaneously, in order to generate very high-resolution continuum and spectral-line images of cosmic radio sources
Telescopes are usually separated by thousands of kilometres
Data from each telescope are digitally sampled and stored locally, using high-capacity magnetic tape systems and magnetic disk-array systems
Data are sent and correlated at the central point (JIVE – Joint Institute for VLBI in Europe)
The total flow of data into the central processor is approximately Terabytes per single observation, after processing this is reduced to Gbytes

9. e-VLBI
pilots
Current status of the e-VLBI Proof-of-Concept Telescope Network connections. Five telescopes are connected to their NREN, GEANT & ultimately JIVE at 1 Gbps (Jodrell Bank & Cambridge – UK; Westerbork –NL; Torun – PL; Onsala – SE). Arecibo (USA) is connected at 155 Mbps.

10. User & instruments requirements
Incorporate scientific instruments to become a part of the Grid
Make middleware and underlying technologies transparent for users
Avoid losing sessions while moving around e.g. start an experiment on a workstation at work and finish it on a laptop at home
Low computational requirements on the user side – whole computations on the “server“ side
… And others discovered in the nearest future
Most of these aspects regarding networking and grid have to
be studied - one of the aims of the RINGrid project

12. RINGrid - overview
RINGrid stands for Remote Instrumentation in Next- generation Grids
