Steve Burke (I have not included email address since they are available here http://www.gridpp.ac.uk/members/, please add your self in if you are not there http://www.gridpp.ac.uk/website/gridpp-contacts.html ) + Current LCG is LCG2_0_0 released Wed Apr 7, there are no changes at all other than the version number and the architecture (tier 1 change only) from the previous release lcg2_20040225_1700. + Is it worth having a LCG Getting Started Page on GridPP. This was thought to be useful to have a single page with a few links and nothing else. http://lcgdeploy.cvs.cern.ch/cgi-bin/lcgdeploy.cgi/lcg2/ and docs/lcg2-install-notes.txt. Is the place to start. + Site Status and Reports. o Imperial and London (Dave C, Owen M) Last pre-LCG2.0.0 installed and in reality this is the same thing so nothing to do at this time. Owen Maroney is currently visiting other sites in london, helping and hoping to have the 5 london sites within LCG. o Oxford and South (Rhys Newman) 20 brand new machines have arrived and will be installed now within LCG at Oxford. Experiance gained to be spread then across South Grid. Cambridge is already within LCG. o Birmingham Want to convert current EDG machines to LCG2 machines. o RAL-PPD Starting to install LCG at previous equivalent tag. 4 nodes installed. No problems installing. (Just another LCFG install). o Bristol From Chris Brew 20 nodes for a test cluster in EDG now could go to LCG but no one obvious to do it. Possibly other babar nodes could join in the longer future. o Edinburgh Trying to get front ends together, front ends arriving in a week or two. o Glasgow LCG 2.0.0 installed including lcfg, ce, se, wn, ui all at 2.0.0. Now following the paper work to join LCG2. o Durham 8 front ends available. Plan a manual install of LCG2 in upcoming weeks. The LRM of choice is sun grid engine for which job managers exist. Information providers needed though for this. Dave Colling expresed intrest for LESC who also use SGE. Some 40 nodes running batch would idealy be joined to LCG in time. o Manchester LCFG and CE at LCG2 since yesterday will continue. o Lancastor 26 nodes for LCG2 in the short term. o Liverpool, 500 nodes possible. AOB + General questions about number of boxes. Are all these service nodes required CE, SE, ... ? Comments made that the CE and SE can easily fill up their CPU anyway. + Dave Colling said that frontend boxes form Gridpp were forthcoming for grid interfaces. + Question from Rhys. Where should I looks to see overall architecture document? Lots of blank faces but suggestions of EDG architecture documents and possibly EDG papers in the future. (Perhaps someone could provide links) + GridPP Map. GOC There should be a UK view of Grid resources. Dave Kant and GOC plan to add a UK view of LCG resources. Sites following the LCG install procedure will be added to the map automatically. http://goc.grid-support.ac.uk/, follow the monitoring link from there. + Matt, Which testbed for HEP production work? LCG2 is the definitive answer and to some point at least LCG2 is the same as EGEE production anyway but LCG2 is what exists today and has the longest future. + Santanu. A question about different hardware within the batch workers and how this should be represented in information system. .. You can't , GLUE assumes all hardware is the same. Select some middle ground perhaps with the exception of memory where you should publish the smallest memory available. Next meeting will take place in 3 weeks on the 6th May 2004 at 14:00, I'll post an agenda.
