  1. JRA1 – Annual Activity Report Francisco Brasileiro Universidade Federal de Campina Grande – UFCG (Brazil) Diego Scardaci Istituto Nazionale di Fisica Nucleare – INFN (Italy) TB + EAC Meeting Bogotá, 23.02.2009

  2. TJRA 1.1: Coordination of the Activity • All tasks are followed closely by either the activity manager or his deputy • Communication channels need to be improved • Skype meetings between manager and his deputy at least once per month • Fortnight e-mail summary reports from CIEMAT staff • FB shall establish a permanent communication channel with SA1 management • DS shall do the same for NA3 Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 3

  3. TJRA 1.2: Development of Infrastructure-oriented Additional Grid Services TJRA1.2.1: Seed Resources Sharing OurGrid 4.1.4 has just been released Includes authentication and XMPP-based communication Support for X.509 certificates Support for privacy Application level and resource level security specification Available at http://www.ourgrid.org/ andhttps://forge.eu-eela.eu/projects/ourgrid-eela/ First site already operational at UFCG Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 5

  4. TJRA 1.2: Development of Infrastructure-oriented Additional Grid Services TJRA1.2.2: Porting of gLite to Microsoft Windows platforms Windows port of gLite UI and Computing Element is ready and available at: https://forge.eu-eela.eu/projects/grid2win/ Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 6

  5. TJRA 1.2: Development of Infrastructure-oriented Additional Grid Services TJRA1.2.3: Interoperability between gLite and OurGrid We have moved from a “bridging” approach to a co-existence one OurGrid provides a good interface to run bag-of-tasks gLite is appropriate to support the execution of tightly-coupled applications BoT jobs should be submitted to the best-effort grid, draining these jobsout from the cluster’s queue Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 7

  6. TJRA 1.2: Development of Infrastructure-oriented Additional Grid Services TJRA1.2.3: Interoperability between gLite and OurGrid Guide available in the EOC site for helping administrators of gLite-based sites to install the OurGrid middleware in co-existence with gLite Guide available to install standalone OurGrid-based sites Guide available to write OurGrid jobs Public portal available for testing OurGrid-enabled applications without the need to install the software http://portal.ourgrid.org/ Status and statistics services for the best-effort infrastructure yet to be deployed as a core service See http://status.ourgrid.org/ Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 8

  7. TJRA 1.2: Development of Infrastructure-oriented Additional Grid Services TJRA1.2.4: Application and VO compliant execution environments through virtualization CIEMAT staff allocated to this task had to concentrate on other affairs during the last four months of 2008 Management expects to profit from a face-to-face meeting during the 1st EELA-2 conference to get this activity moving at the CIEMAT side We took advantage of synergy that exists between TJRA1.2.3 and TJRA1.2.4 to reach our milestone OurGrid sites can run customized virtual machines that support the software required by a given VO Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 9

  8. TJRA 1.3: Development of Application-oriented Additional Grid Services • Digital Archives • GSAF is available in a stable version • https://forge.eu-eela.eu/projects/gsaf/ Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 10

  9. TJRA 1.3: Development of Application-oriented Additional Grid Services • Secure Storage Service • Available in a stable version • https://forge.eu-eela.eu/projects/securestorage/ Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 11

  10. TJRA 1.3: Development of Application-oriented Additional Grid Services • Cooperative workflows and tagging • Prototype available for tagging data of Environmental Science Applications • This is a product of the SegHidro Project • Relies on a centralized database for tags • http://opendapmetafinder.lsd.ufcg.edu.br/ • Working on a distributed version • JF’s MSc dissertation Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 12

  11. TJRA 1.3: Development of Application-oriented Additional Grid Services • Additional application-driven grid services • GFAL Java API • The GFAL library presents a Posix interface for the I/O operations • gLibrary/DRI • gLibrary/DRI extends gLibrary, a system with a easy-to-use web front-end designed to save and organize multimedia assets on Grid-based storage resources • SAGE: Storage Accounting • SAGE is a system to measure the usage of storage resources in a gLite based grid infrastructure and make this data available to DGAS (the accounting system of gLite) to account the storage at higher levels • WatchDog • Watches the status of a running job when it runs on a working node • Utilities • A set of utilities that allow users to easily manage gLite Services Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 13

  12. TJRA 1.3: Development of Application-oriented Additional Grid Services • Multiple Middleware Installation • Instruction to install on a single computer a "super" Grid User Interface having clients both for gLite and Globus Toolkit 4 (GT4): https://grid.ct.infn.it/twiki/bin/view/EELA2/SuperUserInterface • Instruction to install on the machines of a single cluster both a gLite Computing Element and a GT4 job allocation manager thus making a "super" Grid Computing Element: https://grid.ct.infn.it/twiki/bin/view/EELA2/SuperComputingElement • We will provide support to Site-Admins for multiple middleware installation • OurGrid co-existence is compatible with multiple middleware resource centres Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 14

  13. TJRA 1.4: Middleware Repository • EELA-Forge Site: • Forge is available at https://forge.eu-eela.eu/ • Customized for EELA-2 • Two project categories • Services for the Applications • Services for the Infrastructure Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 15

  14. Status of forthcoming actions • Accomplishment of MJRA1.2: prototypes running in the validation infrastructure • Was delayed due to the unavailability of this infrastructure • DJRA1.1: Annual Activity Report • FB and DS have agreed on the template and on the division of tasks; first version should be available in the first week of March • MJRA1.4: Prototype of the gateway to transfer jobs from gLite to OurGrid and vice-versa • This milestone has been affected by the change of focus from interoperability to co-existence • Running gLite BoT jobs in OurGrid should be straightforward • We can develop a new OurGrid Broker that is able to parse gLite .jdf files • Running OurGrid jobs on gLite is less interesting,now that the OurGrid-based infrastructure is ableto use the gLite-based one in an opportunistic way Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 16

  15. JRA1 Resources • JRA1 Section in EELA-2 web site • Contains a summary of the activity goals and points to the Wiki site • https://www.eu-eela.eu/ • JRA1 Wiki Site • Contains descriptions and links for each JRA1 services • https://grid.ct.infn.it/twiki/bin/view/EELA2/JRA1Services • EELA-Forge Site • All released software • https://forge.eu-eela.eu/ Bogotá, EELA-2 TB+EAC Meeting, 23.02.2009 17
