FrameworkUnified class design in order to minimize user-written codeUnified class interfaces

Jupiter

5A.Miyamoto at HDCMeeting (1-Oct-2004)

Jupiter Features:

Modular structure for easy update, install/uninstall of sub-detectors Powerful base classes that provide unified interface to

facilitate easy (un)installation of components by methods such as InstallIn, Assemble, Cabling

Help implementation of detailed hierarchiral structures.This helps to save memory size.

Minimize user-written source code by– Automatic naming system & material management– B-field compositions for accelerators

Input 　 : HEPEVT, CAIN (ASCII) or generators in JSF. Output

– Output class allows extrnal methods. Using this mechanism, it can output ASCII flat file and JSF/ROOT fie.

Core developper: K.Hoshina and K.Fujii

Meetings & ML

Since last July, We had two Jupiter developers workshop

Each about ~ 1 week Participants : A.Miyamoto, K.Fujii (KEK), and students from Ko

be, Niigata, Tsukuba, GUAS Regular TV meetings in Tuesday afternoon

Create a mailing list, acfa-sim-j@jlcux1.kek.jp To discuss technical details ( in Japanese )

The host system for developments is jlclogin.kek.jp CVS Master repository : jlclogin:/proj/soft/CVSMASTER

Note: CVS repository of Jupiter and Satellites are updated very frequently A set of libs/execs : jlclogin:/proj/soft/Release/x.xx ( x.xx=1.00 as of June 1, new set will be created soon )

For a remote user, Daily snap shots of CVS repository: http://jlccvs.kek.jp/snapshots/ The Web interface to CVS, http://jlccvs.kek.jp/ Remote access to the CVS repository

CVS access is out of order, due to a security problem.We will restart after the system update, if there is a request.

Or use CVSup ( see http://jlccvs.kek.jp/cvsup/ )

Calorimeter in Jupiter

An accuracy of simulated results depends on precision of Calorimeter geometry.

In the currenet version, we are implementing an ideal geometry to know ultimate performance pointing tower structure, no crack between towers > 100 layes of absorbers and sensors Mini-tower can be defined within tower to small cell structure.

Simulate with a small cell structure and merge cell signals appropriately at later analysis stage to save CPU and storage space.

Tower geometry, materials and granularity can be modified easily.

Current status: Geometry are implemented. Studying performances such as

CPU time, Output data size, Energy response, etc Tower structure

How to build and run Jupiter

You will need, ROOT, JSF, Geant4, CLHEP, …(?)

Get JUPITER source from CVS Set environment parameters, such as JUPITERROOT

See jlclogin:/proj/soft/Release/x.xx/setup.bash for example

Then do “make” at the Jupiter top director. To run, type

$ Jupiter…prompt> /run/beamOn 100 Read pythia_event.data and

hit information is written in a file, hit.dat

17A.Miyamoto at HDCMeeting (1-Oct-2004)

Status of Jupiter

We have spent ~two months to implement fine structures of Calorimeter.

Status CAL tower of ~170 layers of 4cmx4cm tower

~9000sec to generate 100 ZH events at 350 GeV Output data size exceeds 2G Bytes at ~0.5K events

– Need to reduce output data size or JSF update to support multiple-file output

– Without output, run more than 5000 events 1cmx1cm tower

Takes 2 hour for geometry initialization ECAL energy resolution

~19%/Sqrt(E), if this is due to large cut-off, CPU time may be increased in order to get reasonable resolution

Satellites

19A.Miyamoto at HDCMeeting (1-Oct-2004)

Sattelites: IO, Metis, Leda Sattelites are event reconstruction module for simulated data.

IO – Input / Output module set Convert Jupiter output to ROOT object

Though ASCII file JSFJ4 ( Run Jupiter in JSF frame work and convert)

METIS – Monte Calro Exact hit To Intermediate Simulated Output Module set for simulated data reconstruction

Includes – HitMaker : Exact hit to smeared hit– TrackMaker : Track reconstruction– ClusterMaker: Cal. Cluster reconstruction– PartcleFlowObjectMaker : Make Particle Flow Object

Leda – Library Extension for Data Analyis Library for reconstruction

Includes– Kalman filter package, etc.

22A.Miyamoto at HDCMeeting (1-Oct-2004)

Status of Metis

Current aim is to prepare a minimum set of Metis module for studies of Particle Flow Algorithm.

Novice users will be able to do physics analysis using information of PFO classes.

As a first step, a cheated track fitter and cluster maker, etc are in preparation in order to know an ultimate performance.

We are developing basic classes now.

Each modules are independent, thus shall be easy to implement different reconstruction algorithm according to interests
