Update on NSF-ITR Proposal

Bjørn S. Nilsen

The Ohio State University

Ultimate Purpose

• To get the needed computing resources for LHC-RHI in the US.– Hardware

• CPU, Disk-Tape Storage, Local-National-International Networking, Room/Building.

– Software• AliRoot, CMS-Off line, Grid-middle ware (distributed

computing).

– Support• Personal to maintain and run these systems.• Personal to develop the Grid interfaces.

NSF-ITRInformation Technology

Research• 3 Categories 5 years max,

– Small ($500K, Odds Good),– Medium ($5M, $1M/year, Odds middling),– Large ($15M, $3M/year, Odds poor).

• No $ for Federal employees of other agencies.

• $ Equipment < $ Personal (Not an infrastructure program).

NSF-ITRProposal

• 5 Year $3-4M Medium Project.

• Support for ALICE only.

• Core team, OSU, OSC, NCSU.

• 3+ Postdocs for 5 years.

• Hardware placed at OSC.– 60% or more for Hardware.

– Mostly gotten in last 3 years.

• 2 Year $500K Small Project.• Support for ALICE only.• Core team, OSU, OSC.• 2 Postdocs for 2 years.• Hardware

– Use OSC resources via OSC computing grants.

– maybe add some tapes, and workstations.

• Get Hardware in 2004 from other Sources.

BackgroundGrid Activities

USAPPDG, GriPhyN/iVDGL

– ATLAS, & CMS + well represented.– Good connections to Globus &

Condor teams– Improved connections to CERN

needed.– No ALICE connections, being

established now.– Funding

• 2000 GriPhyN $15M 5 years,• 2001 iVDGL $13.65M 5 years,• PPDG $3.1M 1 year?.

EuropeDataGrid / DataTag– ALICE, ATLAS, CMS & LHCb

+ well represented.– Good connections with CERN.– Poor connections with Globus &

Condor teams, their software in use.

– Funding• DataGrid €10M• PPARC GRID €30M.• INFN GRUD €30M• DataTag €4M.

LHCUSAGrid

CMS-RHI• Well connected to DataGrid-

DataTag

• CMS HEP full participants in PPDG, GriPhyN, iVDGL.

• PPDG, GriPhyN, & iVDGL will be integrated into CMS framework by HEP, PPDG, GriPhyN, & iVDGL people.

• Need hardware and people to do RHI software development.

ALICE-USA• Well connected to DataGrid-

DataTag• Connections with PPDG, GriPhyN,

iVDGL to be established.• Need support to integrating PPDG,

GriPhyN, & iVDGL products into ALICE framework.

• Need people and facilities to do this integration.

• Need more hardware and people to do RHI software development.

GriPhyN/iVDGLmeeting

• Mostly internal matters.• General GriPhyN Grid development – VDT• Many CS people unfamiliar with how physics is done.

– User interface – Web.– Talk about using Objectivity – not CERN supported.

• iVDGL takes VDT & disseminates, maintains, and supports it.• First iVDGL meeting.

– Working on Organization.– First year, hardware and <2 cs FTE, later years manpower.– Order of 20% $ goes to hardware.

• iVDGL requested draft MOU’s from “external experiments”. Specifically Federico & Bjørn for ALICE.

iVDGL ALICEMOU

• Get ALICE in the US Grid Game!• Too late to become members of iVDGL/PPDG.• What to do?

– Be recognized as an active partner external “Experiment”– Establish a solid working relation with iVDGL.– Get good support for iVDGL, including PPDG & GriPhyN=VDT.– Be represented on selected iVDGL boards/working-groups

(Steering committees, Oversight committees, and the like).– Get access to iVDGL test bed for ALICE Grid tests.– Supply iVDGL with resources via OSC and NERSC.– Share ALICE technology (AliEn, AliRoot, ALICE Proof

applications).

ALICE SoftwareActivities

• Continue evolutionary development of AliRoot framework.• After intensive physics testing, we have stopping further development

with GEANT 4 Monte Carlo.• Integration of the FLUKA Monte Carlo.• Starting development of a Geometric modeler & data base.• An ALICE distributed data catalog and production framework

developed, AliEn (Grid in reverse).• First ALICE full scale production started

– Test production of pp-Pythia events completed.– Pb-Pb production starts 10/24/01

• AliRoot 3.06 released 10/10/01– Patched update released 10/24/01 (requires ROOT 3-02-02).

Conclusion

1. ALICE production is underway using existing technologies.

2. We have a chance to get involved with iVDGL if we act soon.

3. ITR proposal for short term funding is in the works

4. Still much work to be done.
