In order to assess both the computing needs of physicists analyzing
BaBar data and the capabilities that exist within the collaboration
for performing BaBar analysis away from SLAC, the CCG is conducting
a survey.  Full and accurate response to this survey will allow us to set
computing priorities so as to better address your needs and those of
BaBar as a whole.  Thanks in advance for your help.
 

Physics analysis activity

Please indicate in the following table what percentage of the access to
primary physics analysis data by people from your institute falls into each
category.  How you weight the activity of individuals in your group is
up to you.  By construction the sum of all entries in the table should
total 100%.
 
 

computing resources data format	SLAC	institute/ regional centre
Objectivity micro	40%	10%
Kanga	40%	10%
PAF
other (specify)

To what extent do you need access, for PHYSICS ANALYSIS (code
development and calibration are addressed elsewhere in this survey), to more
detailed information than that contained in the microDST (e.g. the RECO
or RAW information)?  20% other than micro.

Which data visualization and histogramming tools are used in your
group ( PAW / ROOT / PAF / other )? 90% PAW, 10% ROOT

Which utility packages do you use for kinematics, etc.
( BetaTools / PAF / other c++ tool / FORTRAN tool )? BetaTools

For the analysis activity done at SLAC, does your group use its own
workstations for accessing data (via locally stored data sets) in
addition to using the central SLAC resources?  If yes, how much of your
SLAC based analysis activity is done on these workstations? Yes, 25%
 

Core and subsystem code development and calibration

What event store data (raw/rec/esd/tag) do you use for code testing,
algorithm development and/or calibration?  All used.

Is any of the calibration work done exclusively on esd (micro)?  No

Where do you access this data (i.e. where is it stored)? SLAC central systems.

How much of the core and subsystem code development and calibration
work in your group is performed on your own computing hardware?  25%
 

BaBar computing hardware available at your institute

On what platform(s) do/will you perform BaBar computing at your
institute?

SUN

What resources (cpu, disk and tape storage) are available for BaBar
analysis at your home institute?  Include all equipment that is
already funded.

E450
3 x 400 MHz CPU
2.5 Gb memory
1 Tb disk
35 Gb DLT7000

BaBar software installation at your institute

If you have BaBar software installed at your home institute:

We are currently in the process of setting our system up and installing  Babar software.

- When did you first install BaBar software?
- Is objectivity installed?   Not yet.
- How much manpower was needed to install BaBar software at your institute?
- What is the most recently installed BaBar release?
- Do you maintain multiple releases?
- How often do you update releases?
- How much manpower is needed to update a release?
- Have you produced any MC samples (not necessarily as part of the BaBar central production)? No
- Have you validated the MC samples produced at your institute (i.e. checked that they give identical
    results on well-defined test samples)?

How much manpower is available to support BaBar software installation
and updating at your home institute?
20% of one person's time.

Data storage at your institute

What types of BaBar data have you imported, and in what quantity?  For
each data format listed below please indicate one of:
   T = small test samples,
   S = meaningful subsets of the total dataset (e.g. skims),
   A = most or all of the dataset (e.g. the isPhysics stream).

None imported yet. Answers reflect our plans.

   Objectivity micro  T and S
   Kanga files      T and S
   PAF files
   Other
 

Data import to your institute

Does your group use the standard data distribution tools?  Which ones?

Plan to import through RAL

Does your group perform its own skims at SLAC in order to import data?

No
 

General items

The BaBar site computing contact list (SITECON) is very outdated.
Please give the name of the most appropriate person at your institute
for contact regarding BaBar computing issues.

What additional feedback or questions do you have for the CCG?

None
