ACAT = Advanced Computing and Analysis Techniques in (High-Energy) Physics Research
Originated as "Artificial Intelligence is High Energy Nuclear Physics. The AIHEP92 conference was the first time WWW was presented outside of CERN (World Wide Web - An information infrastructure for High-Energy physics).
Location was spectacular
Program was (of course) heavily slanted to LHC. Lots of stuff on Root.
Surprisingly little emphasis on GRID (taken for granted – or everyone is sick of talking about it?)
