6. 28-Apr-03D.P.Kelsey, CHEP03 report6 Observations (DPK) In general, well organised, but … –Program difficult to follow (too many versions!) –Parallel speakers not identified Plenary was in a very large theatre –Front half was less comfortable So everyone sat at the back –Difficult to ask questions – few microphones Parallel sessions were (often) more interactive –But so many of them! CHEP used to aim for mix of physicists, computer scientists and Industry – not sure it achieves that so well these days Wireless network worked well –Sign-on to UCSD web to get access to DHCP and router –Network problems one morning Speakers that day got the best attention!

7. 28-Apr-03D.P.Kelsey, CHEP03 report7 The Wenaus Summary I attended (some of) Parallel streams 1 and 2 (GRID) –Don’t intend to give a summary of those today So will show some of Torre Wenaus’ Summary slides (See separate link from HEP SYSMAN web page).
