Summary of comments following the USAG 20090402 meeting notes' publishing http://indico.cern.ch/materialDisplay.py?materialId=minutes&confId=55267 ========================================================================= These comments are taken into consideration in the new OLA for TPMs http://indico.cern.ch/materialDisplay.py?materialId=0&confId=57766 draft. * The TPM decentralisation advantages are: . more scalable . closer to the users * Neverteless, there will, probably, never exist as many TPM teams as EGI NGIs, so the decentralisation model will be full of exceptions. * EGI.org must supervise and coordinate the NGI TPM teams and provide a central TPM role in addition. * TPMs are not just ticket dispatchers but real Grid generalists. NGIs must build this knowledge or get others to provide this service for them. * It is important to decentralise without fragmenting! * Dedicated, infrequent shifts will always be necessary. * The most serious support problems are due to the, often, poor middleware quality, a situation likely to get worse in EGI as there is no channel to influence that. Glite figures by S. Burke: 997 patches in total, of which 132 were rejected, 181 were obsoleted by a replacement and 435 are in production). * All the effort invested so far in monitoring and support are proof of failure for the Grid. * Scheduling a EDG/EGEE I,II,III catharsis meeting would be useful. * As the COD work is also being decentralised use common tools and procedures where possible. ------------------------------------------------------------------------ Comments mostly by Steven Burke, Ron, Jeff, Vera, Dimitris, Helene, Fred, John Gordon (in no particular order) assembled by Maria on 2009-04-28
