QuickSim overview

Purpose: simulate detector effects for physics study Components:

VTX, IT, TPC, CAL Model for tracker

circular trajectory parabolic trajectory With multiple scattering, without energy loss Equally spacing sampling

Model for Calorimeter EM signal by e/, HD signal by hadron, muon no signal Segmented calorimeter. Lateral spreads are generated by an analytic form.

Detector configuration is determined by input ASCII file.

Common data sample (Jun06)

Full simulation data sample for detector stuides Data sets: dec05, mar06, may06, jun06 Links available at http://ilcphys.kek.jp/soft/ A kind of data

Single , k0L, , 0, e-, at 1 – 500 GeV : 1K or 10k events E+e- uds quarks pair, ccbar, bbar at 91.18, 200, 350, 500, 10k-20k events Cain background data E+e- ZH lepton + qqbar, 4-jet, 2-jet events at 350 GeV

Producing data as much as possible. Statistics limited by CPU resources.For example, with Xenon 3GHz

Uds 91.18 GeV : 10 k events : 11.7 CPU days/17GB Uds 500 GeV: 10k events(~O(10 1/fb)): 37.7 days/34GB CAIN 10 bunch data: 48GB

Towards GRID

Needs for GRID At each institutes, computing resources are hidden behind

firewall Current solutions

WEB/FTP : needs to transfer data inside fire wall to outside VPN : Can make a direct connection, but not efficient to

transfer large data Future solutions (hope)

Share data by Data GRID Middle ware:

– EU – LCG, NA – OSG, Belle Other GRID system– ECFA group: Developed ILC VO on LCG– KEKCC: Development – new middle ware. Will support LCG.

How to proceed– Define ILC VO using KEKCC hardware + disks for ILC

Trying to connect to Tohoku and Kobe First use will be to share CAIN data Collect information from outside Japan
