Organization of Operations Site registration New sites register themselves by opening a ticket in the support system using the same form as used in EGEE for GOC-DB registration. Sites which are not part of testbed, are also registered in GOC-DB to become candidates for production. Sites adapt EGEE policy for a joining site. This includes mode of operations, announcements as well as security policies and contacts. Updates and upgrades Smaller updates are installed by sites upon being published with EGEE broadcasting tools. Large scale updates (new release of middleware, operating system changes, urgent security updates) are centrally coordinated. Testbed systems test new releases and updates before installed on production sites. EGEE ROC Meeting, Karlsruhe, 5th February 2007

Organization of Operations Support system Local use: RT (request tracker) system at http://support.balticgrid.org/ For tickets which span further than just BalticGrid we use GGUS. Production sites also respond to tickets opened centrally through GGUS. RT used for both site support as well as user support. Operations meetings Joint meetings with SA1, being a weekly VRVS meeting through discussion of active issues as well as a round table discussion going through all sites SLA-s All Baltic NREN-s have signed an SLA agreement with BalticGrid to provide the level of networking neede by the project (first time in Europe for Grids) EGEE ROC Meeting, Karlsruhe, 5th February 2007

EGEE ROC Meeting, Karlsruhe, 5th February 2007 Infosites portal Was originally designed to do more intensive stress testing to see problems which don’t show up during quick SAM tests Is gathering data about sites and provides that in an easy format http://infosite.balticgrid.org/infosite/ EGEE ROC Meeting, Karlsruhe, 5th February 2007

EGEE ROC Meeting, Karlsruhe, 5th February 2007 Accounting issues RGMA stability causing serious concern Accounting information almost never up to date incomplete publishing number of views with different caching periods We had serious problems gathering the accounting data for the first review JRA1 of BalticGrid has studied different accounting systems and chosen DGAS as a potential alternate accounting system DGAS test servers being installed as we speak Will try as seamless as possible integration with gLite and will share the experience EGEE ROC Meeting, Karlsruhe, 5th February 2007

EGEE ROC Meeting, Karlsruhe, 5th February 2007 SL4 and IA64 A lot of sites waiting for SL4 upgrade possibility Not only WN and UI, but also other services like WMS, RB, BDII Some hacking has allowed to run some of the services already now, but these are dirty hacks In addition BalticGrid has quite a number of clusters on IA64 architecture and would like to see when they will be able to join gLite middleware (currently running LCG 2.7) A timeline to the future would be appreciated EGEE ROC Meeting, Karlsruhe, 5th February 2007

EGEE ROC Meeting, Karlsruhe, 5th February 2007 Tutorials Used to use Gilda for tutorials during summerschool had a clash of three separate events on Gilda causing problems for students Now we use BalticGrid testbed for tutorials as well as some smaller clusters All Hands Meeting in Riga in October ‘06 already used the infrastructure with good results We plan to extend the usual tutorials with more advanced gLite demonstraction like parametric jobs as well as data management Should help users to their first steps with real applications as these will no doubt use more than just hello world EGEE ROC Meeting, Karlsruhe, 5th February 2007

Plans for the coming year Official targets 2M computing hours 100 users (already met in year 1) 10 disciplines 6 application codes 20 international collaborations 2 certified sites per country by end of project (done) Concentrating on better support infrastructure ticketing system now as a primary method rotating shifts for ticket watch Better application support more advanced tutorials to help users get the real feeling of the power of Grid Specialized groups who visit scientists and help them to port their application to Grid And of course better collaborations with associated projects, but I think we are doing already pretty good there EGEE ROC Meeting, Karlsruhe, 5th February 2007

EGEE ROC Meeting, Karlsruhe, 5th February 2007 Conclusions BalticGrid and EGEE very similar EGEE Northern ROC Manager and BalticGrid Project Director the same person Helps a lot in communications between the two projects In most cases EGEE infrastructure for central services is being used GGUS ticketing GOC-DB Most sites registered in EGEE as well Same middleware of course Will experiment around with some tools and provide the feedback back to other related projects DGAS BalticGrid infosites Tycoon for computing SLA enforcement (far future) EGEE ROC Meeting, Karlsruhe, 5th February 2007
