Grid Colombia Workshop with OSGWeek 2 Startup Rob Gardner University of Chicago October 26, 2009
Welcome! • I am happy to be joining Jose for another week of learning and working with Grids • This week will be a bit different: • Aimed towards the site administrator • Fewer presentations (very few) • More hands-on
My background • I’m a high energy physicist but have been working on various grid projects for nearly a decade (!) • Computer science projects: PPDG, GriPhyN & iVDGL • Grid infrastructure: Grid3, OSG and WLCG • My science community has been the CERN ATLAS Collaboration, and its Software and Computing projects • For the last few years: • OSG Integration and Sites coordinator • Facility Integration Program manager for USATLAS • Manager of an ATLAS Tier 2 (+2kCores, 0.5 PB,10G) • You’d think I’d have some good answers by now
Launching a Grid Colombia • Phase I: • preparations in advance of the in-person workshop • Phase II: • workshop on scientific computing on Grids and Grid prototype building (that’s this workshop!) • Development of a program of work • Phase III: • deployment of production facilities across multiple sites in Colombia
Second Week’s Goal • Build a prototype Grid Colombia gc2 gc1 gc3 GOC GCO gc4 gc5
Site Architecture • Each site will be the equivalent to this • Condor • Globus: gram, gridftp • User interface (local & grid) • Ganglia monitor
The OSG: a simple site VDT middleware Includes gLite components
The OSG: a typical Tier 2 site STORAGE .. the hardest part dCache system; others: XROOTD, Lustre, GPFS, HDFS (Hadoop)
GOC services (I) • GOCs are facilities usually provided at the national level as part of a NGI (National Grid Infrastructure) • They can host services for more than one “Grid Facility” • Services as part of EU-based EGI, etc (EELA) • Services as part of an OSG-like Grid • (as yet, OSG only has one GOC but peers with GOCs in EGEE as part of WLCG)
GOC Services (II) • There are many services provided by the GOC • Organizational (registration db, web portals) • Security (RA) and Operations (tickets, calls) • Technical services (hosted grid central services) • Here we will focus on technical services • Information service based on ReSS • CEMon Aggregator + BDII • Gratia (Accounting) • RSV (Resource validation monitoring)
Sites, Central Services & Users … Sites Users & VOs GOC
Virtual Organizations (VO) • Virtual Organizations are communities of researchers with shared interests and resources • We will use the OSGEDU VO • We will learn how to: • Request certificates (for real) • Retrieve & install them (host + browser) • User, hosts, service • Gain entry into the OSGEDU VO • Use the OSGEDU VOMS on GridCo site
Teams • Will divide into teams: • Site builders • Build a small cluster with Condor, an OSG compute element, storage element (GridFTP), worker nodes, a grid user management system • GOC team • Install, configure, validate central “goc”-like services such as an information system
Organization • We’ll start each day with team reports from previous day • Will have a lecture each morning focusing more in depth on a component • Teams must “validate as you go” • To make certain services & configuration are correct • Teams must “document as you go” • So you’ll have a record of what you did here to reproduce in your own lab
