From: Ernst, Michael [mailto:[log in to unmask]] Sent: Tuesday, October 16, 2007 8:28 AM To: Gardner, Rob; [log in to unmask] Cc: Ernst, Michael Subject: DRAFT Agenda for Tier-2/Tier-3 Meeting at SLAC Rob, Wei, Please find a first draft of the agenda below. -- Michael The concept is based on the idea to divide the meeting into 3 parts 1.) Day 1: Overview talks and discussions 2.) Day 2: Hands-on with tutorials and demos 3.) Day 3: Site reports and summary discussions & planning Day 1 -------- Overview talks and discussions 9:00 LHC and ATLAS Status (J. Shank) 9:30 Facilities Status & Plans (M. Ernst) 10:00 ? 10:30 Coffee 11:00 Facilities Integration Program (R. Gardner) 12:00 - 14:00 Lunch Production & Physics Analysis in ATLAS 14:00 Production & Analysis process and functional requirements at U.S. ATLAS Tier-2 and Tier-3 centers 15:00 Running Physics Analysis on local and grid computing resources - some examples Day 2 -------- For day 2 I propose to cover for themes. The agenda details have to be worked out. Fabric Hardware (it was obvious how interested attendees in Bloomington were in this area) - Compute Servers - OS choices (32/64 bit, etc) - Installation management - Disk Subsystems o Configuration, resilience, performance, etc ... suitable in the context of Tier-2 & Tier-3 centers, Sizing of Tier-3's relative to physics analysis tasks and expected funding profile Fabric Services - Batch (Condor, PBS) functionality and configuration examples - Storage Management Systems for Tier-2 and Tier-3 centers o Xrootd (Ofer Rind, BNL) o dCache (Neha, FNAL and OSG) Hands-on installation and configuration - Data Transfer Optimization o Report from WG (Shawn) * Findings / Analysis * Mechanisms to improve the performance OSG Grid Middleware - Setting up a CE - Hands-on w/ installation & configuration - Installation and usage of client tools - The OSG Information System - how it works and what's in there (US) ATLAS Services - Installing and using o Distributed Data Management Tools * DQ2 and Pandamover * LRC o PanDA Workflow Management System o ATLAS Software * Demo for PanDA based installation - Running the entire Physics Analysis chain w/ PanDA, PROOF & Xrootd o A full demonstration based on a "real" analysis scenario The hands-on sessions will require some pre-requisites, i.e. some machines at either/and/or BNL, UC, SLAC we can use to do the installations and demos. Day 3 (9:00 - 13:00) 9:00 - 11:20 Site reports 11:20 - 13:00 Summary Discussion & Planning Please let me know what you think and add/change/remove as you see things fit. Thanks, Michael
