1. Grid Colombia Workshop with OSG Week 2 Startup Rob Gardner University of Chicago October 26, 2009

2. 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 2

3. 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  3

4. 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 4

5. Second Week’s Goal Build a prototype Grid Colombia 5 GOC GCO GOC GCO gc2 gc1 gc3 gc4 gc5

6. Site Architecture Each site will be the equivalent to this Condor Globus: gram, gridftp User interface (local & grid) Ganglia monitor 6

7. The OSG: a simple site 7 VDT middleware Includes gLite components

8. The OSG: a typical Tier 2 site 8 dCache system; others: XROOTD, Lustre, GPFS, HDFS (Hadoop) STORAGE.. the hardest part

9. 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) 9

10. 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) 10

11. Sites, Central Services & Users 11 Sites GOC … Users & VOs

12. 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 12

13. 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 13

14. 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 14
