7 UCSD SAN DIEGO SUPERCOMPUTER CENTER Fran Berman Who are SDSC’s “customers”? What role does digital data play in their research?

8 UCSD SAN DIEGO SUPERCOMPUTER CENTER Fran Berman Major Earthquakes on the San Andreas Fault, 1680-present 1906 M 7.8 1857 1680 M 7.7 How dangerous is the San Andreas Fault? Researchers use geological, historical, and environmental data to simulate massive earthquakes. These simulations are critical to understand seismic movement, and assess potential impact. Simulation results provide new scientific information enabling better Estimation of seismic risk Emergency preparation, response and planning Design of next generation of earthquake-resistant structures Results provide information which can help in saving many lives and billions in economic losses ? Data and Simulations -- TeraShake

9 UCSD SAN DIEGO SUPERCOMPUTER CENTER Fran Berman TeraShake Visualization Simulation of Southern of 7.7 earthquake on lower San Andreas Fault Physics-based dynamic source model – simulation of mesh of 1.8 billion cubes with spatial resolution of 200 m Simulated first 3 minutes of a magnitude 7.7 earthquake, 22,728 time steps of 0.011 second each Simulation generates 45+ TB data Project leadership: Tom Jordan (SCEC), Bernard Minster (SIO) Reagan Moore (SDSC), Carl Kesselman (ISI)

10 UCSD SAN DIEGO SUPERCOMPUTER CENTER Fran Berman Resources must support a complicated orchestration of computation and data movement 47 TB output data for 1.8 billion grid points Continuous I/O 2GB/sec 240 procs on SDSC Datastar, 5 days, 1 TB of main memory Data parking of 100s of TBs for many months “Fat Nodes” with 256 GB of DS for pre-processing and post visualization 10-20 TB data archived a day Finer resolution simulations require even more resources. TeraShake being scaled to run on petascale architectures TeraShake Data Choreography Parallel file system Data parking “ I have desired to see a large earthquake simulation for over a decade. This dream has been accomplished.” Bernard Minster, Scripps Institute of Oceanography

11 UCSD SAN DIEGO SUPERCOMPUTER CENTER Fran Berman TeraShake at Petascale – A qualitative difference in prediction accuracy creates even greater data infrastructure demands Estimated figures for simulated 240 second period, 100 hour run-time TeraShake domain (600x300x80 km^3) PetaShake domain (800x400x100 km^3) Fault system interaction NOYES Inner Scale200m25m Resolution of terrain grid 1.8 billion mesh points 2.0 trillion mesh points Magnitude of Earthquake 7.78.1 Time steps 20,000 (.012 sec/step) 160,000 (.0015 sec/step) Surface data 1.1 TB1.2 PB Volume data 43 TB4.9 PB Estimates courtesy of the Southern California Earthquake Center Petascale platform will allow much higher resolution for very accurate prediction of ground motion

12 UCSD SAN DIEGO SUPERCOMPUTER CENTER Fran Berman Data as a driver – the Protein Data Bank: A resource for the global Biology community The Protein Data Bank Largest repository on the planet for structural information about proteins Provides free worldwide public access 24/7 to accurate protein data PDB maintained by the Worldwide PDB administered by the Research Collaboratory for Structural Bioinformatics (RCSB), directed by Helen Berman January 2007 Molecule of the Month: Importins Complex of 3 proteins which aids in protein synthesis by ferrying molecules back and forth between the inside and the outside of the nucleus through tube- shaped nuclear pores Growth of Yearly/Total Structures in PDB 1976-1990, roughly 500 structures or less per year 2006: > 5000 structures in one year, >36,000 total structures Each structure costs roughly 200K to generate. 2006 holdings will have cost roughly $80B in research investment

13 UCSD SAN DIEGO SUPERCOMPUTER CENTER Fran Berman How Does the PDB Work? Data collected, annotated and validated at one of 3 worldwide PDB sites (Rutgers in US). Infrastructure required: 20 highly trained personnel and significant computational, storage and networking capabilities. SDSC machine room Search Fields FLAT FILES Remote Applications DB INTEGRATION LAYER Query Result Browser Query Result Browser Structure Explorer Structure Explorer FTP tree (downlo ad ) SearchLite CORBA Interface KEYWORD SEARCH DERIV ED DATA CORE DB BMCD WWW User Interface New queries New tools New queries Infrastructure: PDB portal served by cluster at SDSC. PDB system designed with multiple failover capabilities to ensure 24/7 access and 99.99% uptime. PDB infrastructure requires 20TB storage at SDSC PDB accessible over the Internet and serves 10,000 users a day (> 200,000 hits) H. Berman estimated that in 2005, more than $1B of research funding was spent to generate the data that were collected, curated, and distributed by the PDB.

20 UCSD SAN DIEGO SUPERCOMPUTER CENTER Fran Berman Increasing Need to Sustain Digital Data for the Foreseeable Future UCSD Libraries Digital State and Federal records The Entertainment Industry The Private Sector The Public Sector Researchers and Educators

21 UCSD SAN DIEGO SUPERCOMPUTER CENTER Fran Berman What data is the most valuable? Key criteria Irreplaceable Longitudinal Used by many Expensive Needed in the future Culturally or scientifically meaningful … Federal records Data needing rescue Irreplaceable data Time-series Reference collections

22 UCSD SAN DIEGO SUPERCOMPUTER CENTER Fran Berman Key Challenges for Digital Preservation What should we preserve? What materials must be “rescued”? How to plan for preservation of materials by design? How should we preserve it? Formats Storage media Stewardship – who is responsible, and for how long? Who should pay for preservation? The content generators? The government? The users? Who should have access? Print media provides easy access for long periods of time but is hard to data-mine Digital media is easier to data-mine but requires management of evolution of media and resource planning over time

23 UCSD SAN DIEGO SUPERCOMPUTER CENTER Fran Berman Preservation and Risk Entity at risk SizeWhat can go wrongFrequency Minimum number of replicas needed to mitigate risk Administrative support FTEs File~2 MB Corrupted media, disk failure 1 year 2 copies in single system System Admins Tape~200 GB + Simultaneous failure of 2 copies 5 years 3 homogeneous systems + Storage Admin System~10 TB + Systemic errors in vendor SW, or Malicious user, or Operator error that deletes multiple copies 15 years 3 independent, heterogeneous systems + Database Admin + Security Admin Archive~1 PB + Natural disaster, obsolescence of standards 50 - 100 years 3 distributed, heterogeneous systems + Network Admin + Data Grid Admin Less risk means more replicants, more resources, more people
