Software Updates

Offline analysis code is located in

the SPD account on the LXPLUS cluster

(standard password). Other

software available by mail request –

also installed in the lab computers

October 8, 2002 P. Nilsson, SPD General Meeting 4

Threshold Scan Analysis – M.C. Version

Selectable number of chips (1-10)

Many changes in the underlying ROOT macros (25 files)

ROOT menu

Ex. Threshold distributions

(PostScript file are automatically

generated)

In collaboration with Carmen, Alex, Peter and Mike

VME Interface(s) for the Digital PILOTIN DEVELOPMENT

Will be ready this week

- hopefully

Decoder Tool

For decoding raw data and consistency checks

Given a Test Beam raw data file as input, it creates a web page

with graphical hit information for a selectable number of events

Test Beam 2002 Web – elogbookElectronic logbook with connections to

Microsoft Access database via

ASP/VBScript – supplement to paper

logbook, not yet replacement

HOWEVER

Compared to paper logbook, elogbook is in

many ways superior

E.g. easy access – world wide but can be IP

restricted, no need to make paper copies,

searchable, cheap color pictures!!!, etc..

Offline AnalysisIn collaboration with Karoly Banicz

• Code written by Karoly• Major upgrade from last year (3 planes N planes)• NEW: Can now be run in batch mode that will disable the histogram displays and the interactive root session

lxplus > bsub TestBeam –batch input.parJob <141374> is submitted to default queue <8nm>

To view status of submitted job:lxplus > bjobs 141374JOBID USER STAT QUEUE FROM_HOST EXEC_HOST JOB_NAME SUBMIT_TIME141374 pnilsso EXIT 8nm lxplus063 lxbatch545 *h input.par Oct 5 21:01

Output data file is stored where specified in the input.par file. When the job is finished, LSF will send an email to the user.

• Code is stored in the SPD account on the LXPLUS, in the ~/analysis/release directory. Will only run on a Linux system• Information/help on how to run the analysis code can be found in the accompanying README file

Offline Analysis – Analyzed Files

Status of the offline analysis can be found

on the Test Beam web

Analyzed files are stored in the SPD

account on the LXPLUS cluster

Offline Analysis - Efficiency

UNDER INVESTIGATION…

Elusive FIFO shifts prevent us from making nice plots

Handpicked burst with no obvious shift show an efficiency of ~99.6%
