•Distributed Computing and Data Management based in Australia(Tom Fifield, Martin Sevior) and Korea (Kihyeon Cho, JungHyun Kim, Soonwook

Hwang, Sunhil Ahn, Taesang Huh) ... with support from China (Wenjing Wu, Yan Liang Han [ 韩艳良 ]), Japan (Go Iwai [ 岩井剛 ]), Poland (Rafal Grzymkowski, Milosz Zydbal), Slovenia (Marko Bracko) USA (Leo Piilonen, David Asner, David Cowley, Brian Ermold, Michael Peterson) and all the people on the nextslide

•Thanks to Ruth Pordes (OSG VO creation), Brian Bockelman and Burt Holzman (EGI interoperability, getting things running), and Douglas Olsen (OSG security).

•Thanks to the DIRAC team, without whom this would not be possible.

B and B-bar meson pairs are produced

Flight a short length, then decay into light stable particles

Beautiful measurement of Matter-Antimatter asymmetry

But…

Too small for Observed Universal Matter-Antimatter difference!

Belle II – Upgrade

New experiment to increase the intensity of the accelerator by a factor 50!

will collect 50x more data

Start up 2014-2015

3 PB data (KEK, PNNL) => 150 PB data (GRID, gLite, OSG)

Search for Physics beyond the Standard Model withPrecision measurements

•Proposal to DOE funded till June 2012•Proposal to DOE for continued fundingin preparation•BASF installed on NW-ICE cluster•7 racks of 27 compute nodes (8 cores)•Priority use of ½ of 1512 cores•Validated MC produced for Exp43, Exp45•140 TB disk / 1 PB tape storage for•Belle data/MC populated via FTP

Approval for Belle computing to occupy new Computer Science Facility (CSF)900 TB disk acquired/deployed for Belle 1

Future:Additional servers (up to 400 cores)Large data transfer from Japan

Intention to become OSG Grid Site

Belle Computing at PNNL : Status 7/5/11

The Grid

EGI-OSG Interoperable VO - 13 countries

Jobs submitted using DIRAC (of LHCb fame)

Input defined by Metadata queries (powered by AMGA) Works on the idea of a 'Project' – collection of jobs, different data

per job, same analysis code Data source in Japan, distributed worldwide on demand

50PB raw by 2016, with lots more derived/simulation data

Belle II Status

Japan remains committed to Belle II

Official groundbreaking ceremony Nov. 18th, 2011

(Many dignitaries from around the world in attendance)

Data expected in 2015

Outlook to 2012

Great Japan EarthQuake (March, 2011) Still looking for help!

Finding grid-skilled people is a challenge (Tom Fifield 90% => 10%)

Building experiment-specific software Busy arranging resources, signing MoUs

~60 institutes to organise 1st delivery of equipment for our “Tier 0” Q1 2012

5PB storage (+5PB for original Belle) As many cores as budget will allow

Virginia Tech incorporated into OSG Pacific NorthWest National Lab starts process to join OSG Belle data “liberated” => plan for deployment late 2011 Look to develop grid/OSG and analysis tools for Belle by early 2012
