1 Mobility aspects in remote
instrumentation Damian Kaliszan Norbert Meyer, Marcin Lawenda, Dominik Stokłosa, Marcin Okoń, Tomasz Rajtar Poznań Supercomputing and Networking Center, Poland New Delhi, December 15th, 2006

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 Call: FP Infrastructures-7 Specific Support Action Contract no Duration: 18 months, from October 2006 – March 2008

13 RINGrid Objectives: Identification of instruments and user communities, definition of requirements Synergy between remote instrumentation and next-generation high-speed communications networks and grid infrastructures Trend analysis and recommendations for designing next- generation remote instrumentation services Promoting egalitarian access to European e-Infrastructure opportunities Dissemination of project results to scientific and business groups of users Collaboration with other projects e.g. GridCC, EXPReS, int.eu.grid and groups e.g. e-IRG

14 Countries targeted Other EU member states, EU candidate countries,
The RINGrid project aims at enhancing scientific cooperation with: Other EU member states, EU candidate countries, Countries in Latin America Poland, Austria, Italy, Romania, Bulgaria, UK Mexico Brazil Chile India in the future?

15 Division of work – current status
WP1 - Project management WP2 - Identification of instruments and user communities, definition of requirements – results: end of Dec 2006 WP3 - Evaluation and requirements for infrastructures WP4 - Future emerging trends and recommendations WP5 - Dissemination, standardisation and cooperation with other projects WP6 - Prototyping and verification

16 Identified infrastructure 1/2
Preliminary identified instruments from different scientific domains Europe: bioorganic chemistry, radio astronomy, spectroscopy, satellite communication, telecommunication, high-voltage engineering, environment quality assessment and pollution control Latin America: material science, laser scan microscopy, diffractometer, food processing Poland Scientific field: Biooganic Chemistry Equipment Varian UNITY 300MHz NMR spectrometer BRUKER AVANCE 600MHz NMR spectrometer Radio Astronomy 32m Radio Telescope in P iwnice, Poland

17 Identified infrastructure 2/2
Brazil Scientific field: Material Science at LNLS Equipment Synchrotron Light Source  – 11 beam lines JEOL High Resolution Transmission Electron   Microscope (HR-EM), model JEM 3010 URP JEOL Field Emission Scanning Electron Microscope (FEG-SEM), model JSM-6330F JEOL Low Vacuum Scanning Electron Microscope (LV-SEM), model JSM-5900LV Optical Astronomy at LNA 4.1 m optical telescope at Southern Astrophysical Research Telescope  (SOAR), Cerro Pachón, Chile  Full list available on the RINGrid project web site

18 RINGrid – network infrastructure
Topology of RedCLARA Topology of GEANT2 155 Mbps backbone ring (BR, AR, CL, PA, MX) Spur links from 10 to 45 Mbps to other countries 622 Mbps link from Brazil to GÉANT in Madrid

19 Verification & prototype environments
Testbeds: PSNC Virtual Laboratory (http://vlab.psnc.pl/) GridCC (www.gridcc.org) CLARA (www.redclara.net) Objectives: Specification and working out of ‘use cases’, which match the profile of requirements set by the previous work packages Preparation of prototype installations Execution of tests and collection of remarks concerning results achieved and user experiences, documenting all relevant information in a formal report Analysis of the verification process results and production of a coherent list of recommendations for instrumentation grid infrastructures

20 Future collaboration with EU-Indian partners
EU-India high-speed communication links for students and researchers opened (October 2006), State-of–the-art on high-speed networks and grid infrastructure as a base for possible future collaboration, Rediscovering new instrumentation that could be incorporated to the grid environment eScience & Digital libraries aspects Establishing contacts between scientists from EU and India – searching for new user groups and capability of extending RINGrid community Cooperation with ERNET Worldwide approach – large number of facilities (instrumentations)
