The SciDAC Program is alive and well

and needs you to … Present some scientific results - “tied” to SciDAC Demonstrate the benefits of working

collaboratively (together and with the Computer Scientists)

Help make the case for increased funding for the next stage of the program, Hardware and Networking Infrastructure (Topical Computing centers in your terms)

Budgets across Office of Science

In FY2000 request was for $60M growing rapidly to $120M/ year

FY2001 actual budget – total of $57.3M ASCR $37.4 M (~ $3.15M -> HENP) BES $ 1.9 M BER $ 8.0 M FES $ 3.0 M HENP $ 6.9 M

FY2002 pretty much flat-flat

High Energy and Nuclear Physics SciDAC Program

The HENP SciDAC program consists of 5 projects Science and Simulation of Particle Accelerators

• complex and expensive tools used throughout DOE for scientific discovery

Supernova Science (2 projects)• to discover the fundamental mechanisms of these complex natural

systems Lattice Gauge Theory calculations

• to test and explore the Standard Model (QCD) and to interpret NP and HEP experiment results

Particle Physics Data Grid (joint with ASCR)• Collaborative tools for large geographical dispersed researchers

needing access to data and computing resources

2/1/2002 SciDAC Lattice All-Hands Meeting, Jlab Slide 11

High Energy and Nuclear Physics SciDAC Yearly Budgets

The HENP SciDAC projects Science and Simulation of Particle Accelerators

• $1.8M + $0.8M ASCR

Supernova Science (2 projects)• $1.25M/year + $0.4 M ASCR

• $ 0.52M/year + $0.12M ASCR

Lattice Gauge Theory calculations• $1.85M/year + $0.13M ASCR

Particle Physics Data Grid (joint with ASCR)• $1.44 M + $1.7M ASCR

SciDAC Project Portfolio – other offices

Basic Energy Sciences ($2M) Bunch (~ 11 ) of small

awards

Biological and Environmental ($8M) Climate (~15 sub-

awards)

Fusion ($3M) 5 projects (1 carry-over)

ASCR ($37M) 6 Grids & Portals 5 Networking 7 Integrated Software

Infrastructure Centers (ISIC)

“Glue” money for integrating science projects with the ISIC and helping with other Computer Science holes

Some hardware

Recent Principal Investigator (PI) meeting

Was to be a grand kickoff meeting in Sep. 9/11 derailed that

Held Jan 16/17 in Washington DC area

Chance for Support and interest of Jim Decker Foster collaboration – use ISICs, cross

fertilization

Challenges for HENP SciDAC

Extend our traditions of huge international collaborations for experimental science into Theory and Computational Science work in multi-disciplinary teams, build community codes to

deal with the size and complexity of the problems apply innovative math and computing techniques and

algorithms to problems work effectively together (Collaborative Tools/Grid)

Strive for science deliverables soon and harness all the human and computing resources to meet the science goals

2/1/2002 SciDAC Lattice All-Hands Meeting, Jlab Slide 15

Challenges for HENP SciDAC

Evolve the scientific codes to run on the multi-Teraflop computers of tomorrow Portable, scalable codes that can use today’s

resources for scientific discovery and be prepared for the next generation of computing resources

Well layered, structured and supported community-wide codes

Instrumented codes to optimize performance and understand the type of computers that will meet the needs in the most cost effective manner

2/1/2002 SciDAC Lattice All-Hands Meeting, Jlab Slide 16

Presentations from 2 of the HENP SciDAC projects

Both have gone a long way in forming true multi-disciplinary collaborations with strong ties to applied mathematicians and computer scientists

Both have scientific goals with some short-term results expected, that they will tell you about Shedding New Light on Exploding Stars: Terascale

Simulations of Neutrino-Driven Supernovae and their Nucleosynthesis (Mezzacappa – PI)

Advanced Computing for 21st Century Accelerator Science and Technology (Ryne, Ko – PIs)

2/1/2002 SciDAC Lattice All-Hands Meeting, Jlab Slide 17

SciDAC center for Supernova Research (Woosley – PI)

Funding for 2 labs and 2 universities

Good start on multi-disciplinary team Many applied math

and computing challenges

Synergy with other projects?

Impact of a supernova on an adjacent star

2/1/2002 SciDAC Lattice All-Hands Meeting, Jlab Slide 18

National Computational Infrastructure for Lattice Gauge Theory (Sugar- PI)

Huge strides made in collaborative approach + starting to work with computer scientists on performance

metrics and optimization of code

Accurate computations of important scientific constants requires tens of Tflop years Need highly cost-effective Topical Computing Centers for

Lattice QCD – aiming at below $1/Mflop and targeting two different machine architectures – (1) Custom built for QCD and (2) Commodity PC Clusters with low latency networking

Results from PI meeting

HENP Posters were a great success

HENP Presentations went down very well Material from Mezzacappa presentation used by

senior ASCR person in recent talkVery good HENP visibility

Many mentions in others talks. Every ISIC effort strongly driven by an HENP application

Many connections to Computer Science effortsNice words from Ed Oliver
