1 “ National Knowledge Network and Grid - A DAE Perspective ” B.S. Jagadeesh Computer Division BARC. India and CERN: Visions for future Collaboration 01/March/2011

2 Our Approach to Grids has been an evolutionary approach Anupam Supercomputers To Achieve Supercomputing Speeds –At least 10 times faster than the available sequential machines in BARC To build a General Purpose Parallel Computer –Catering to wide variety of problems –General Purpose compute nodes and interconnection network To keep development cycle short –Use readily available, off-the-shelf components

3 ANUPAM Performance over the years

4 ‘ANUPAM-ADHYA’ 47 Tera Flops

5  Processing ( parallelization of computation)  I/O ( parallel file system)  Visualization (parallelized graphic pipeline/ Tile Display Unit) Complete solution to scientific problems by exploiting parallelism for

6 Snapshots of Tiled Image Viewer

7 We now have, Large tiled display Rendering power with distributed rendering Scalable to many many pixels and polygons An attractive alternative to high end graphics system Deep and rich scientific visualization system

8 Post-tsunami: Nagappattinam, India (Lat: ° N Lon: ° E) This one-meter resolution image was taken by Space Imaging's IKONOS satellite on Dec. 29, 2004 — just three days after the devastating tsunami hit. 1M IKONOS Image Acquired: 29 December 2004 Credit "Space Imaging"

9 So, We Need Lots Of Resources Like High Performance Computers, Visualization Tools, Data Collection Tools, Sophisticated Laboratory Equipments Etc. “ Science Has Become Mega Science” “Laboratory Has To Be A Collaboratory” Key Concept is “Sharing By Respecting Administrative Policies”

10 User Access Point Resource Broker Grid Resources Result GRID CONCEPT

11 Grid concept (another perspective) Many jobs per system One job per system Two systems per JOB Many systems per JOB View all of the above as Single unified resource -- Early days of Computation -- Risc / Workstation Era -- Client-Server Model -- Parallel / Distributed Computing -- Grid Computing

12 LHC Computing LHC (Large Hadron Collider) has become operational and is churning out data. Data rates per experiment of >100 Mbytes/sec. >1 Pbytes/year of storage for raw data per experiment. Computationally problem is so large that can not be solved by a single computer centre World-wide collaborations and analysis. –Desirable to share computing and analysis throughout the world.

13 LEMON architecture

14 QUATTOR Quattor is a tool suite providing automated installation, configuration and management of clusters and farms Highly suitable to install, configure and manage Grid computing clusters correctly and automatically At CERN, currently used to auto manage nodes >2000 with heterogeneous hardware and software applications Centrally configurable & reproducible installations, run time management for functional & security updates to maximize availability

16 Nationwide networks like ANUNET, NICNET,SPACENET did exist Idea is to Synergize, Integrate and leverage to form National Information Highways Take everyone onboard (5000 institutes of learning). Provide quality of service.Outlay of Rs 100 crores for Proof of Concept Envisaged applications are: Countrywide Classrooms, Telemedicine, E-Governance, Grid Technology ….. National Knowledge Network
