Cluster <strong>Computing</strong> <strong>and</strong><strong>Visualization</strong> on GridPresentation for4th <strong>Garuda</strong> Grid Partners’ Meet @ Bangalore 2008Dr. C.S.KumarAssociate Professor, ME Dept
Introduction of Lab• A computational <strong>and</strong> visualization facility forscientific applications• The computational facility created to meet therequirements of CORAL <strong>and</strong> IIT Kharagpur• Initial support through IBM’s SUR grant of USD 50K<strong>and</strong> IIT Kgp support of similar amount• To be scaled up with the computational needs thefaculty, researchers <strong>and</strong> students increase on thenetworkC S Kumar @ IIT Kgp, , <strong>Garuda</strong>Partners’ Meet 2008

Digital Video Online• IIT Kgp has vast repository of educational material onDigital Video hosted at Centre for EducationalTechnology (CET)• Over 140 courses with 30-40 hrs per course is online• Several of these are made available through NPTEL• Now some of these can be pre-viewed onhttp://10.130.0.8 as a <strong>Garuda</strong> IP address• Video available as streaming CIF MPEG2 (768 mbps)• H.364 (mpeg-4 4 part 10) 4 CIF (1 mbps) also beingcoded – (decoding may require licences)• Full access details can be worked out with CET at IITKharagpurC S Kumar @ IIT Kgp, , <strong>Garuda</strong>Partners’ Meet 2008
Other educational tools beingdeveloped• Learning management system based on moodle forcourse management is being developed.• Remote Classroom using Access Grid is setup on a testbed.• High Definition Video / Digital Video transport based liveevent streaming made available (using multicast) – 30mbps b<strong>and</strong>width : very useful for live broadcast ofsurgical sessions <strong>and</strong> virtual reality laboratories withaugmented reality• Virtual Labs for 11 courses being readied – remotelyoperable labware <strong>and</strong> highly interactive simulations indifferent fields of CSE, ECE, EE <strong>and</strong> ME being madeavailable initially.C S Kumar @ IIT Kgp, , <strong>Garuda</strong>Partners’ Meet 2008
Access Grid for collaboration• A Grid communication middleware basedframework for collaboration (current versionGlobus 3)• Uses scalable multicast network technology formultiple sites (not limited to 1+4 / 1+5 etc as inMCU)• Multiple display technology can be leveraged• High definition video can be added• Additional use specific components can benstalled.C S Kumar @ IIT Kgp, , <strong>Garuda</strong>Partners’ Meet 2008

Access Grid experiment using QoS TestBedC S Kumar @ IIT Kgp, , <strong>Garuda</strong>Partners’ Meet 2008
Current status• Setup created under a QoS network project <strong>and</strong>experiments are on with Access Grid <strong>and</strong> lowb<strong>and</strong>width QoS networks• High b<strong>and</strong>width multicast access with campusLAN• Experience <strong>and</strong> technology can be ported to<strong>Garuda</strong> Grid for multi-site use• Some remote site infrastructure planning isrequiredC S Kumar @ IIT Kgp, , <strong>Garuda</strong>Partners’ Meet 2008
