**Ian Hinchliffe (Lawrence Berkeley Laboratory)**

Migration to the LCG Genser Project for Herwig and Pythia was completed
In January 2004. The Pythia version migrated to 6.220 and older versions
dropped. Output of all event generators to AthenaPool is fully
operationa l at the end of January. The ATLAS system if Units was
migrated to MeV/mm as completed in January 2004. This change affected
all of the WBS items under 2.1.

Work began on making Sherpa (fully C++ generator) available in February.
After interaction with the Sherpa authors this code was made available
to the collaboration in March 2004. The EvtGen (b-decay) package became
available in February 2004 and will be used in production in DC2.

Implimented the Cascade event generator in March 2004. This is based on
a more sophisticated version of the QCD parton model and is optimized
for processes of low mass.

First version of Jimmy made available in February 2004. This is an
add-on package to Herwig that is needed to properly describe underlying
events. A migration to Herwig 6.505 was necessary and was completed in
March. Jimmy entered validation at the end of March with the intent that
it be used ion DC2. More involvement of physicists in the validation of
this tool is needed before it can be used for large scale event
production.

Validation for event generation for DC2 started In February 2004. This
web site can be consulted for details. http://phyweb.lbl.gov/\~ianh/dc/.

During this quarter, major effort was directed towards establishing the
software for the Combined TestBeam and Data Challenge 2. The production
release for the simulation and digitization phase (Release 8.0.0) of DC2
went as on schedule. Validation of this release is ongoing and several
bug-fix releases are ongoing based on the findings of the validation
exercise. Once a robust release is produced, this will be used for the
simulation production exercise. Work in ongoing to establish all the
reconstruction software components - This release is expected end of
June and to be used both by the DC2 reconstruction exercise and the
Combined Test Beam.

The major U.S. deliverable in Core software during this phase included
the delivery of pile-up support, event mixing and pool based persistency
for Event Data Objects.

An Analysis Tools group was formed with K. Assamagan from BNL leading
the group. This group has had several meetings and a workshop to develop
and deploy a framework for physicists to perform their analysis. A
prototype framework with associated software tools is expected to be
available together with the DC2 reconstruction release.

**Joe Boudreau (University of Pittsburgh)**

Our top priority during Jan-Mar 2004 was to connect the GeoModel
detector description to the simulation, and to test that it was usable
in DC2. The detectors which were involved were: the entire inner
detector, and the muon chambers. A decision was taken to not use the
GeoModel description of calorimeters DC2. In January the entire inner
detector could be translated into G4, and interoperate with sensitive
detectors (the name given to classes which produce hits from true
particle trajectories). However, the validation of the hits thus
produced took until approximately the beginning of March. The muon
chambers (in January) existed but had not been translated into G4. We
carried this out translation, assured interoperability with G4, and then
did an extensive set of validations as with the inner detector.

The chief validation done in all detector subsystems is hit-relocation;
that is, checking that hits which were produced from a translated
geometry can be re-located in space using the same geometry. This is
done not only visually but also using high-statistics residual plots. A
partial log of these activities can be found here:
http://agave.phyast.pitt.edu/cgi-bin/machlog.pl?nb=dd&action=view&page=last
(one should start here and reverse through the time sequence of
activities). The Jan-March activities appear to have been successful,
and now all of the tracking detectors will take their description from
GeoModel in DC2.

**Note #1**  Significant progress has been made in the deployment of an
Analysis Framework. A prototype is expected to be deployed for DC2 by
June 2004

**Note #2**  A prototype implementation has been released. A more mature
software release is not yet deployed and a separate milestone is
assigned to reflect iteration.

**Note #1**  This activity is partly covered under Distributed Analysis
Tools and a prototype is expected to be deployed for use in DC2.

**Note #2**  This is work is partly covered under Grid Tools and
Services to provide monitoring of jobs submitted on the Grid. No
capability within Athena exists due to lack of any assigned resources.

**Note #3**  The integration has been delayed due to lack of manpower.
Work on standalone distributed file replication services are in progress
and needs to be completed before integration with Athena can be
established.

**2.2.3 Database** **David Malon (ANL)**

Progress in all areas has been noted in the detailed milestone reporting
contained in the subsections. Delays, when they have occurred, are
largely due to reprioritization as functionality requirements for Data
Challenge 2 and the 2004 combined test beam have become clearer.

NOVA milestones will need to be revisited in the coming months as the
new ATLAS-wide geometry database project takes shape. An expected
LHC-wide distributed database deployment project will also change
database servers and services milestones. These planning adjustments
will likely be made late in the July-September reporting period.

The U.S. ATLAS database effort was augmented in the current reporting
quarter by the addition at Argonne of Jack Cranshaw, who brings HEP
database expertise based upon previous CDF experience.

P. Nevski (BNL) serves as the ATLAS GEANT3 Coordinator.

S Rajagopalan (BNL) is the overall ATLAS LAr software coordinator. He
coordinates activities in the LAr sub-system domain and closely
collaborates with other sub-system group such as the Tile and Trigger
groups.

F. Luehring (Indiana) serves as the TRT Software coordinator and is the
Inner Detector software librarian. Luehring also is served ATLAS
software release coordinator for the end of the quarter when he replaced
Goldfarb (Michigan see below).

D. Costanzo (LBL) serves as the Pixel GEANT4 simulation and digitization
coordinator. Costanzo serves as the ATLAS Digitization and ROD
Processing Coordinator for the Inner Detector. Costanzo serves as the
overall ATLAS-wide digitization coordinator.

S. Goldfarb (Michigan) is the muon system software coordinator. Goldfarb
served as ATLAS software release coordinator during part of the quarter.

M. Leltchouk (Nevis) serves as the LAr simulation coordinator.

P. Loch (Arizona) continued to work on the simulation of the FCAL
prototype modules for the combined testbeam simulation. Loch also
provided some coordination with the other detector communities for the
GEANT4 simulation of the FCal and the combined testbeam.

P. Nevski (BNL) continued to provide GEANT3 simulation support. The
basic maintenance and support continues to be needed during the GEANT3
to GEANT4 transition stage.

F. Luehring (Indiana) maintained the TRT GEANT3 simulation. He also
coordinated work on the GEANT4 TRT simulation and use of GeoModel in the
TRT simulation.

D. Costanzo (LBL) helped lead the ATLAS GEANT4 based simulation
deployment. In preparation for Data Challenge 2, Costanzo simulated
several thousand events to ensure that the ATLAS offline software was
ready for production. Costanzo actively participated to this activity
both managing it and contributing on the technical side of the work.

D. Costanzo (LBL) continued code maintenance for the pixel simulation in
GEANT4 and the C++ digitization package used by both the pixels and SCT.
Costanzo also maintained the GeoModel code for the Pixel detector.

K.Benslama, M. Leltchouk, J. Parsons, W. Seligman (Nevis) also completed
a number of tasks to prepare LAr GEANT4 simulation to work within Athena
for use in Data Challenge 2. The region production cuts for all liquid
argon calorimeters were introduced and tested. The EM barrel, EM endcap,
and cryostat codes were checked and updated. Validation of LAr
simulation was done for releases 7.7.0, 7.8.0, and 8.0.0. A bug in EMEC
hit identifier calculation for Z\<0 have been found and fixed. Plans for
validation of the physics models in GEANT4 were discussed at LAr
Software Working meeting held on 23 February 2004
(http://agenda.cern.ch/fullAgenda.php?ida=a04847) where Leltchouk spoke
on: \"EMEC/HEC G4 Validation Plans\". The fast-shower-model code for the
EM barrel integrated to the LAr GEANT4 simulation.

J. Boudreau and V. Tsulaia (Pittsburgh) worked to connect the GeoModel
detector description to the simulation, and to test that it was usable
in Data Challenge 2. In January the entire Inner Detector could be
translated into GEANT4 using the GeoModel description of the detectors,
and interoperate with sensitive detectors (the name given to classes
which produce hits from true particle trajectories). However, the
validation of the hits thus produced took until approximately the
beginning of March. Boudreau and Tsulaia also carried out the GeoModel
to GEANT4 translation for the Muon system, assured interoperability with
GEANT4, and then did an extensive set of validations as with the Inner
Detector.

K. De and M. Sosebee (Texas Arlington) Finished processing simulation
and re-digitization of 120k top events for high eta physics study.
Sosebee generated these events (2400 data files generated) using U.S.
ATLAS resources, including BNL, Boston, Indiana, Texas Arlington and
PDSF (LBL/NERSC).

improvements. Loch also did routine maintenance work and bug fixes for
the full FCAL reconstruction.

P. Loch (Arizona) also contributed design aspects and code to the
implementation of the new event data model in the liquid argon
reconstruction software domain.

D. Costanzo (LBL) helped lead the work on adapting the ATLAS
reconstruction to work with events produced by the new GEANT4 based
simulation. In preparation for Data Challenge 2, Costanzo reconstructed
several thousand GEANT4 events to ensure that the ATLAS offline software
was ready for production. Costanzo actively participated to this
activity both managing it and contributing on the technical side of the
work. This work lead to having a robust, functional reconstruction that
worked with GEANT4 events and was ready for final optimization before
the start of Data Challenge 2.

S. Goldfarb (Michigan) contributed to the ATLAS Muon Reconstruction by
coordinating work on and planning development of the Moore
Reconstruction Program. His work focused on the move to a tracking event
data model that is common with the Inner Detector Group and on the
converters needed to produce common output objects (tracks) to be used
by the combined reconstruction.

M. Leltchouk, W. Seligman (Nevis) continued their work on LAr
calibration hits. They tested methods of energy classification in GEANT4
using a toy calorimeter Monte Carlo and the created a prototype for
calibration hits in the HEC. The status of this work was reported at the
Calorimeter Calibration meeting held on 26 January 2004
(http://agenda.cern.ch/fullAgenda.php?ida=a04335) where Leltchouk spoke
on \"Methods of hadronic shower energy classification in G4\" and
Seligman spoke on \"Status of calibration hits in LArG4\". A talk about
this work was also given at the LAr Software Working meeting held on 23

K. Assamagan (BNL) was appointed the ATLAS Analysis Tools coordinator
during this quarter.

D. Costanzo (LBL) was appointed ATLAS-wide Physics Software validation
coordinator during this quarter.

A. Savine (Arizona) continued to study the electronic calibration system
and developed code to classify channels by their reflection pulse shape.

P. Loch and A Savine (Arizona) also started to get involved into the new
physics analysis tools working group. They mainly provided relevant
input to the design discussion at a dedicated workshop at London late
March.

K. Assamagan (BNL) has been named the ATLAS Analysis Tools coordinator.
Assamagan is coordinating the effort in the development of a framework
that allows physicists to perform physics analysis. An initial prototype
the analysis framework is expected to be ready for Data Challenge 2.

D. Damazio and F. Paige (BNL) are also involved in analyzing SUSY and
Z→ee data samples to validate the simulation and reconstruction
software.

K. Baker and T. Shin (Hampton) continued the simulations of graviton
production and decay in ATLAS with an aim to making the connection to
Dark Energy/Cosmological Constant. We updated our simulations from
release 6.5.0 to 8.2.0 in order to interface with the Physics Analysis
Tools (PAT) Working Group. This group plans to use our work and results
as one of the Use Case examples in filling and using Analysis Object
Data (AOD\'s).

Y. Gao and L. Lu (SMU) have been working on testing new analysis
strategy to search for new particles at LHC with detailed simulation.
The idea is based on Gao\'s preprint hep-ex/0310011.

R. Engelmann (Stonybrook) did an analysis of 100,000 Higgs (130 GeV) → 4
lepton (electron and muon) events doing the full chain Pythia, GEANT3,
Athena Reconstruction and PAW ntuple analysis.

**2.2.4.5 Trigger** **Frederic Luehring (Indiana University)**

W. Wiedenmann and H. Zobernig (Wisconsin) created and tested several
prototypes for the High Level Trigger (HLT) code repository. Regular
builds and releases will be made available based on corresponding
Online-, Dataflow- and Offline-releases.

W. Wiedenmann and H. Zobernig (Wisconsin) worked on integration of muon
and electron/gamma slice. The work included setting up and testing the
selection slices from the available releases and studying deployment
procedures for the combined testbeam. A working meeting was held to
review the status of multithreaded software for the Level-2 trigger. The
main effort then concentrated on integrating the muon selection slice
with the Level-2 development environment \"athenaMT\" (multi-thread
implementation of Athena). After a debugging and testing phase of about
two weeks, the selection slice was running successfully in athenaMT. A
large effort went into making the code thread safe. During the debugging
and testing phase many software issues were identified both on the
infrastructure and algorithm level. The electron/gamma selection slice
T2CALO was integrated in the Level-2 environment with offline release
8.0.1

W. Wiedenmann and H. Zobernig (Wisconsin) tested the muon selection
slice on distributed dataflow system. A distributed data flow system was
set up on the HLT testbed with recent software releases. This was done
to fully test the muon and electron/gamma selection slices in a
realistic trigger setup for the testbeam. A series of meetings was
started to follow up this muon integration effort and to bring together
on a regular basis all contributing parties.

in the event display, including a wired 3D view and lego plots.

F. Luehring (Indiana) spent a week at CERN organizing the simulation of
TRT for this summer's combined testbeam.

D. Levin (Michigan) has developed a package MUTRAK that is used for H8
and cosmic ray test stand data analysis. MUTRAK is standalone set of
routines that decodes the data for a variety of formats (from MiniDAQ or
from H8), generates drift time spectra, hit distributions and measures
such parameters as maximum drift time, T0s, rise and fall times, chamber
and ASD electronics noise, and relative tube/channel efficiencies. In
tracking mode it performs an auto-calibration, generates RT functions
and track display, residual and resolution measurements. A placeholder
exists for it in the ATLAS CVS repository - although the software is not
yet installed.

M. Leltchouk and W. Seligman (Nevis) continued to work on special
calibration hits for the combined testbeam GEANT4 simulation.

Y. Gao, L. Lu, and R Stroynowski (SMU) worked on a note on the LAr
testbeam entitled "Electron identification and e-pi separation with
barrel Module P15" (ATL-LARG-2003-013).

R. Engelmann (Stony Brook) worked on cluster corrections in the EM
barrel using the summer 2002 P13 testbeam data, which were reconstructed
with the EMTB package by LAPP into ntuples. The LAPP package for the
analysis of these ntuples is being used to generate cluster corrections
to be compared with LAPP talks. This package will also be used for the
current CTB runs with the LAPP/Stonybrook corrections incorporated into
the CBT Athena package.

**2.3 Subsystem Manager\'s Summary** **Bruce Gibbard (Brookhaven
National Laboratory)**

As of the end of the reporting period facility fabrics at both the Tier
1 and Tier 2\'s as well as the wide area network were fully ready for
the beginning of DC2. Work in the area of Grid Tools and Services and
Production were making good progress but delivery of final versions and
the start of DC2 will be delayed by the late delivery of the DC2
applications software.

The second quarter saw the Tier 1 facility achieve full operational
capacity to support ATLAS Data Challenge 2. With significant upgrades to
the Linux Farm and the storage systems, the facility is now operating at
approximately 5% of the expected scale for 2007. The Tier 1 staffing was
significantly increased with three new hires (two of whom will start at
the beginning of the third quarter). This brings the Tier 1 staffing to
a total of 7.5 FTEs.

**2.3.1.1 Management/Administration** **Richard Baker (Brookhaven
National Laboratory)**

During the quarter, recruitment efforts were successful with the hire of
three new staff members. Gabrielle Carcassi started work in February and
will focus on integrating Grid authorization into the Tier 1 fabric. Xin
Zhao and Zhenping Liu are expected to start in April, 2004. Xin will
focus on direct support of ATLAS Data Challenge 2 and Zhenping will work
on Grid integration of the Tier 1 storage systems.

**2.3.1.2 Tier 1 Fabric Infrastructure** **Richard Baker (Brookhaven

**Note #1-3**  DC2 will startup late due to delays in ATHENA software
release.

**2.3.5.1 Software Acceptance** **Kaushik De (University of Texas at
Arlington)**

ATHENA acceptance: The production group has run some tests with
pre-production ATHENA releases. During this quarter, we are primarily
waiting for the DC2 version of the ATHENA software to become available.
Work is continuing on the pile-up software by Pavel Nevski.

GTS acceptance: Nurcan Ozturk and Mark Sosebee have done some initial
alpha tests of the GCE client. We are waiting for the first beta
versions to test real jobs on the grid using the new Windmill-Capone
system.

Windmill acceptance: We received various versions of Windmill, the
supervisor software for the automatic production system, which were
tested and improved. Wensheng Deng, Nurcan Ozturk, Mark Sosebee and
Horst Severini worked on Windmill testing.

The first functional Windmill system, version 0.4, capable of running a
single job queue, was released on February 4th by Kaushik De. This was
tested thoroughly by the production group.

Windmill version 0.5 with multi-queue capabilities was released on
February 23rd.

Windmill version 0.6 was released on March 8th. This version was
integrated with the Oracle production database for the first time. It
also contained a grid job simulator, Rocinante to test automated
production. Thousands of simulation jobs were run for testing and
debugging.

Windmill version 0.7 was integrated with the DC2 data management system,
Don Quichote, and released on March 15th. At this stage we started
testing and debugging simple real jobs on the grid.

All the Windmill and rocinante software in this quarter were developed
and tested by the U.S. production team. Windmill is a common production
framework for international ATLAS - this system will be used by all
groups/grid in ATLAS for DC2.

**2.3.5.2 Deployment of Software Services** **Kaushik De (University of
Texas at Arlington)**

Deployment and testing of software services on the GRID3 (testbed) sites
was carried out by Ed May. Work continued with new releases of GRID3
infrastructure and GCE clients.

**2.3.5.3 Validation and Hardening** **Kaushik De (University of Texas
at Arlington)**

Ed May, Horst Severini and various site managers continued work on
validation and hardening of the testbed sites. The software acceptance
team provided valuable feedback on validation and hardening of the
Windmill and GCE systems.

**2.3.5.4 Operations** **Kaushik De (University of Texas at Arlington)**

During the first quarter of 2004, operations continued on two fronts -
support for physics groups using DC1 software, and installation,
development and testing of the new DC2 software. Routine maintenance and
management of resources at all the grid testbed facilities, in support
of production, was also carried out.

We welcome the addition of Wensheng Deng and Xin Zhao to the DC2
production effort. Wensheng and Mark Sosebee are in charge of DC2
operations, while Xin is responsible for software installations and
validation.

The largest sample produced during this period was a 120k event high eta
top sample. A typical job from this sample took half a day to complete.
1200 such jobs were completed using the grid testbed at BNL, BU, IU, UTA
and LBNL. 1200 additional jobs were also produced (with almost a factor
of 10 shorter run times) at central etas. Finally, the 1200 file high
eta sample was redigitized on the grid. Mark Sosebee at UTA carried out
this production exercise, using the DC1 GRAT software. Additionally,
almost a 1000 low eta samples were produced using the new GCE software,
by the GTS group, as a preliminary test for DC2 preparations, but using
the DC1 versions of ATHENA.

The top data production produced over 8,000 files, all of which were
registered and moved using Magda. Verification of these files and the
entire dataset was ongoing at the end of the quarter. We expect to
complete verification and transfer the files to CERN in early April
using Magda.

The second major task by the operations team was development and testing
of the DC2 production system. Over 30,000 simulated jobs were run with
the Windmill system during this quarter, the vast majority of which were
run in the U.S. All members of the production team contributed to this
effort.

Mark Sosebee and Wensheng Deng continued cleanup of DC1 files from
testbed sites.

**2.9 Subsystem Manager\'s Summary** **Jim Shank (Boston University)**

Activities in this quarter were driven by two high level milestones: The
ATLAS Data Challenge 2 (DC2) and the Combined Test Beam (CTB). Both of
these are scheduled to start in May, 2004. Our facilities, both Tier 1
and the proto-Tier 2's funded by iVDGL, were ramped up considerably in
preparation for DC2. Significant new hardware acquisitions occurred at
University of Chicago, Indiana University and Boston University using
iVDGL funds. In addition, our T1 center at BNL ramped up hardware and
support personnel for DC2. Our Grid Tools and Services (GTS) area
activities were all focused on getting the new ATLAS production system,
in which we will be demonstrating large-scale grid interoperability,
fully functional. Our software effort was concerned with getting the
functionality for DC2 as well as the CTB. One notable achievement in the
software area for DC2 is the incorporation of the US developed, GeoModel
as the sole mechanism for simulation, the major component of the first
phase of DC2. Our DB software development team was busy with
deliverables for both DC2 and CTB.
