6. Scientific Linux (1)  Launched 10 years ago when the conditions had changed  Now they have changed again (agreement between Red Hat and CentOS) – we need to (re-)act  Clear, enlightening presentations  Passionate discussion  My own conclusion: HEP community strongly prefers to take a common approach

7. Scientific Linux (2)  Very constructive discussion on Tuesday with Connie Sieh, Jarek Polok, Tim Bell, HM  CentOS still not stable enough – too early to take firm decisions on SL  HEP should try and participate in CentOS discussions and decisions  Launch Scientific SIG with contributions by (at least) FNAL and CERN  Each team to build respective SL release when RHEL 7/CentOS 7 get released  Both teams to observe and maintain active dialogue  Review of situation, possibly decision at fall HEPiX meeting

8. Board Meeting (1)  Current and next meetings  Working groups  IPv6: plea to attend WLCG pre-GDB in June  Benchmarking: see report.

Yaim replacement to be considered  Bit preservation: see report  Energy efficiency: despite active effort, no positive echo. Go into passive (observing) mode
