<br />
N.B.: As with many others I missed the start of the meeting because of<br />
20cm of snow overnight. I had to join by EVO in the morning.<br />
<br />
===GGUS===<br />
<br />
Talk summarised improvements in GGUS system (improved availability).<br />
<br />
More frequent tests of alarm system, now managed by GGUS team. Some<br />
discussion of how often (once a week, regular is too often, but should<br />
test after changes to system).<br />
<br />
==Technical Forum==<br />
<br />
Main issue has been about multi-user pilot jobs. Maatren summarised<br />
the issues and discussion so far, this is the useful URL:<br />

<br />
Philippe Charpentier proposes links to descriptions of the experiment<br />
frameworks so that people can understand what is involved. Much more<br />
worried about data security. Considers<br />
<br />
Are we fudging established security policy (Steve Newhouse)?<br />
<br />
PC - policy was decided without scrutiny of frameworks. Why no review<br />
of middleware itself?<br />
<br />
Kors - in favour of fixing all security holes; but most worried about<br />
putting extra hurdles in the way of analysis at a critical<br />
time. Maarten/John - this supports option 4, while gaining<br />
experience.<br />
<br />
Michele Jouvin proposes reviewing questionnaires in a pre-GDB.<br />
<br />
In addition: other working groups are proposed, related to data<br />
management in the main.<br />
<br />
===JSPG Policies===<br />
<br />
Some feedback on user registration - often good suggestions which have<br />
been incorporated and helped to simplify and generalise the policies.<br />
<br />
New policies for AUP and Site Registration have been<br />
circulated. Comments by end of January.<br />
<br />
===Middleware===<br />
<br />
Proposal to drop gLite 3.1 two months after gLite 3.2 version has been<br />
demonstrated to be 'good working service'.<br />
<br />
I asked about the impact on code portability by encouraging a<br />
development/build monocoluture. Oliver and others thought there was no<br />
so great an impact. There seems to be little demand for gLite on other<br />
platforms.<br />
<br />
CMS would like a 32 bit version of the UI on SL5.<br />
<br />
Proposal to rationalise the meta package versions to be more<br />
meaningful.<br />
<br />
===OSG===<br />
<br />
Updated on OSG activities, mainly within WLCG context.<br />
<br />
===Expt Reports===<br />
<br />
====ALICE====<br />
<br />
Prioritised SL5 (almost done) over CREAM CE (not done).<br />
<br />
====ATLAS====<br />
<br />
Basically happy, but concerns about CASTOR at CERN. Need<br />
improvements in SRM monitoring and would like to see discussion about<br />
future of storage.<br />
<br />
====CMS====<br />
<br />
First talk from new CMS computing coordinator, Ian<br />
Fisk. Generally happy with computing operations. Some discussion about<br />
requirements on WNs for cache space - 20GB per core. On high N core<br />
machines will hit i/o limits.<br />
<br />
====LHCb====<br />
<br />
Detailed list of problems seen, but nothing catastrophic. Still<br />
forced to download data to WN at dCache sites because of some dcap<br />
bugs.</div>Graeme stewart
